What value of x is in the solution set of 2x. 3 > 11 - 5x?
a. -3
b. 0
c. 2
d. 4
Answer:
i think option d
Answer:
The answer is D : 4.
Step-by-step explanation:
=2x-3>11-5x
=2x-3+5x>11
=7x-3>11
=7x>11+3
=7x>14
=7x/7>14/7
=x>2
By simplifying the problem, you can see that "x" must be greater than 2. Therefore, eliminating all other possible answers that are shown, but 4.

Answer:
(-1, -7)
Step-by-step explanation:
Solve by graphing.
Graph the two equations together.
The lines intercept at (-1, -7).
Hope this helps.
Answer:
Solution: (-1, -7)
Step-by-step explanation:
6x - 1 = 3x - 4
Subtract 3x from both sides;
3x - 1 = -4
Add 1 to both sides;
3x = -3
Divide both sides by 3;
x = -1
Substitute x into the equation;
y = 3(-1) - 4
y = -3 - 4
y = -7

You have a bag with 6 green marbles, 15 blue marbles, 8 red marbles, 1 yellow
marble. What is the probability (as a decimal rounded to three places) of pulling
out a red marble?
Answer:
0.267 or 26.7%
Step-by-step explanation:
The probability of an event happening is calculated by dividing the favorable outcomes by all outcomes:
The sum of all events (marbles) is 6 + 15 + 8 + 1 = 30
The number of favorable events is 8
Therefore, the probability is 8/30 ≈ 0.267 or 26.7%

=======================================================
Explanation:
Look through the table to see when f(x) = g(x)
This happens when both are equal to 1, which is in the fourth row, or when x = -1.
In other words,
f(-1) = 1g(-1) = 1So f(-1) = g(-1)
We can then say the solution to f(x) = g(x) is x = -1.
Jayson buys a car and pays by installments. Each installment is $567 per month.
After 48 months, Jayson owes $1,250. What was the total price of the vehicle?
================================================
Explanation:
Each installment or payment is $567 per month.
If 48 months go by, then Jayson has paid 48*567 = 27,216 dollars.
If he still owes $1250, then this means he will pay back a total of 27,216+1,250 = 28,466 dollars.

For every 242424 meals Momoka prepared for customers last night, she prepared 222 meals for employees. Momoka prepared 156156156 meals. How many meals did Momoka prepare for customers and for employees last night?
9514 1404 393
Answer:
13 meals for employees143 meals for customersStep-by-step explanation:
2/24 = 1/12 of the 156 meals were for employees. That is ...
156/12 = 13 meals . . . . for employees
The remaining 156 -13 = 143 meals were for customers.
For a soccer practice, the coach set up four cones, labeled W, X, Y, and Z, to mark the edges of the rectangular field.
Suppose the field is drawn on a coordinate plane, where the x- and y-values represent the position, in yards, from the center of the field, which is located at (0, 0). The location of the cones are as follows.
Cone W is located at (-38, -53).
Cone X is located at (-38, 53).
Cone Y is located at (38, 53).
Cone Z is located at (38, -53).
What is the perimeter of the field?
A.
38 yards
B.
364 yards
C.
8,056 yards
D.
182 yards
Answer:
Because there are fewer than 30 (not no more than 30) one of the answer i x+y < 30
Because he needs both small and large another answer is x>0 and not x 0
Finally because he need at least dozen large cones the last answer is y

David says that the numbers 2 and 4 are both composite numbers. Sarah says that 2 is a prime number and 4 is a composite number. Which statement explains who is correct?
Answer: Sarah is correct
Step-by-step explanation:
A composite number is referred to as a positive integer which is gotten when someone multiplies two positive integers that are smaller than the number. We should note that we should not use one while multiplying.
A prime number is a number that can only be divided when the number is being divided by one and itself. Examples are 2, 3, 7, 11 etc.
Based on the above analysis, 2 is a prime number while 4 is a composite number. Therefore, Sarah is correct.
Given h(x)=4x+4h(x)=4x+4, solve for xx when h(x)=0h(x)=0
Answer:
The value of x is -1 when h(x) = 0
Step-by-step explanation:
Given function is:
[tex]h(x) = 4x+4[/tex]
The function is a linear function with one input.
We have to solve for x when h(x) = 0 this means that we have to put h(x) = 0 and find the value of x.
So,
[tex]h(x) = 0\\4x+4 = 0[/tex]
Subtracting 4 from both sides
[tex]4x+4-4 = 0-4\\4x = -4[/tex]
Dividing both sides by 4
[tex]\\\frac{4x}{4} = \frac{-4}{4}\\x = -1[/tex]
Hence,
The value of x is -1 when h(x) = 0
Buckeye truck rentals has a daily rate of $59.99 plus $0.34/mile. Goodyear truck rentals has the same size truck for 58.95 plus $0.36/mile. At how many mile will the cost be the same?
Answer:
52 miles
Step-by-step explanation:
Step one:
given data
Buckeye truck rentals
daily rate of $59.99
plus $0.34/mile
let the number of miles be x
and the total charge be y
so
y= 0.34x+59.99---------------1
Goodyear truck rentals
daily rate of 58.95
plus $0.36/mile
let the number of miles be x
and the total charge be y
so
y= 0.36x+58.95---------------2
Step two:
Equate the two equations above to find x
0.34x+59.99=0.36x+58.95
collect like terms
59.99-58.95=0.36x-0.34x
1.04=0.02x
divide both sides by 0.02
x= 1.04/0.02
x=52 miles
Last month karmin made $480 working for 30 hours this month she will get a 15% increase in the amount she earns per hour what will be her hourly rate In dollars after the increase
Answer:
$18.40
Step-by-step explanation:
480/30= 16
$16 is the amount earned per hour
16×.15= 2.40
$2.40 is 15% increase in the amount she earns per hour
16+2.40=18.40
$18.40 is hourly rate in dollars after the increase

Which statement correctly compares the function shown on the graph wih the function y=5x + 5
Answer:
C the function on the graph has the same rate of change, but a lower starting point
Step-by-step explanation:
they both have the slope of 5, and the graph's y-intercept is -6. -6<5.
Answer:
I would say C. The function shown on the graph has the same rate of change but a lower starting points.
Step-by-step explanation:
I said C because if you look at the slope in the equation which is 5x and look at where the line intercepts the Y axis you can see that the rise if 5 (going up) and the run (going over) is 1 and that gives you the next point. But the 5 in the equation is higher than the starting point on the Y axis so that's why I chose the one that said the lower starting point.
hope this helps.
The sum of two numbers is 2490 and if 6.5 percent of one no. is equal to 8.5 percent of the other, then numbers are ?? Make sure it’s correct answer pls! 20 points for brainliest (also can u tell me how to mark someone brainliest?)
Answer:
The two number are :
x = 1411
y = 1079
Step-by-step explanation:
Let the two numbers = x and y
The sum of two numbers is 2490
x + y = 2490..... Equation 1
If 6.5 percent of one no. is equal to 8.5 percent of the other,
Hence:
6.5% of x = 8.5% of y
0.065x = 0.085y
Make x the subject of the Formula
x = 0.085y/0.065
x = 1.308y
We substitute 1.308y for x Equation 1
x + y = 2490..... Equation 1
1.308y + y = 2490
2.308y = 2490
y = 2490/2.308
y = 1078.8561525
y = 1079
x + y = 2490..... Equation 1
x = 2490 - y
x = 2490 - 1079
x = 1411
Graph the linear equation -x + 2y = 3 by identifying the x- and y-intercepts
Answer: Hopes this helpss
Step-by-step explanation:
to find the x intercept substitute in 0 for y and solve for x
To find the y-intercept, substitute in 0 for x and solve for y
x intercept (-3,0)
y intercept ( 0, 3/2)
There are 15 marbles in a jar: 4 red, 5 green, and 6 yellow. You select one marble and do not replace it. Then, you select another marble. Determine if these events are independent
The events of picking marbles from the jar is independent
An event is independent if the occurrence of one event does not depend on another event.
For example, if you toss a coin and it lands on its head. You then flip another coin and it lands on its tail. These two events are independent. The face the second coin lands on do not depend on which face the first coin lands on. Also, the face that the first coin lands on does not depend on which face the second coin lands on.
In this question, after the first marble is picked, you do not return the first marble into the jar. Then you pick a second marble. The colour of the second marble does not depend on the colour of the first marble you picked. This means that the events are independent.
