Answer:
(2x + 1)(5x - 6)
Step-by-step explanation:
(2x + 1)(5x - 6)
2x + 1 = 0
Subtract 1 from both sides;
2x = -1
Divide both sides by 2;
x = -1/2
5x - 6 = 0
Add 6 to both sides;
5x = 6
Divide both sides by 5;
x = 6/5
61. A survey asked students what classes they
have. Based on the results, the following
statements are all true.
• 34 students have Science
• 28 students have Math.
• 5 students have both Math and Science.
• 6 students have neither class.
How many students were surveyed?
Please help :((
Answer:
63 students.
Step-by-step explanation:
x students.
34 have science 28 have math 5 math and science 6 neither.
6 neither means there were at least 6 students so our number goes up to 6 students.
34 have science 28 have math 5 have both.
34-5 and 28-5

Answer:
me tooo plzzz some one slove this
What is the slope of the line?
Answer:
Its 1/1 or -1/-1
Step-by-step explanation:
Answer:
The slop of the line is 1
Step-by-step explanation:
To find slop of the line you look at rise over run, or the distance from one point to another up then across. In this graph, from the point (0,-3) to (1,-2) you go up one point and across one point. 1/1 = 1 so the slope is 1.
Suppose you go out to eat with a friend and your bill was $25.67. The local sales tax rate is 7% and you want to leave a 20% tip for the waitress. Calculate the 20% tip of $25.67. [tip]
( I need the tip)
Answer:
Umm I'm not sure is it 25...
Step-by-step explanation:
Answer:
Tip= $5.13
Step-by-step explanation:
You can crossmultiply and use the "Is/Of x %/100" method
= X/$25.67 x 20%/100
Cross multiply:
25.67 x 20 = 513.4
Xx100= 100X
To solve for X from here, divide both answers by 100
513.4/100= 5.13
100X/ 100 = X
So...
$5.13 = X

URGENT BRAINLEIST CHANCEWhich of the following expressions cannot be written as an integer?
-3 0
18/3
1.2 × 10 -2
√49
Answer:
1.2*10^-2
Step-by-step explanation:
-3^0 is 1, because anything to the power of 0 (except for 0) is always equal to 1. 1 is an integer, so this is not the answer.
18/3=6, and 6 is an integer, so this is not the answer either.
1.2*10^-2 = 1.2*0.01 = 0.012, which is not an integer, so this is the answer.
49 is an integer, so this is not the answer:
Therefore, the answer to this problem is 1.2*10^-2
Hope this helped!
Answer:
[tex]1.2*(10-2)[/tex] cannot be written as an integer.
Explanation:
Fractions and decimals are not integers. All whole numbers and natural numbers are integers.
You can immediately identify that [tex]1.2*(10-2)[/tex] cannot be written as an integer because the decimal is 1.2 and the only way it could become an integer is if it was multiplied by a number ending in 5 or with 5 as a factor (5,1 0, 15, 20, and so on). Also, it has a decimal point that isn't being multiplied by another decimal/fraction. In some cases, decimals or fractions multiplied by each other can equal an integer, but it's that's not the case in this instance.
However, if you couldn't identify this or you needed to check you answer, you could solve the expressions:
[tex]1.2*(10-2)\\1.2*(8)\\9.6[/tex]
9.6 is a decimal, therefore it is not an integer.
[tex]-3 + 0 = -3\\-3*0= 0[/tex]
I don't know if you were attempting to add or multiply, but in both cases, the sum and product equal an integer.
[tex]\frac{18}{3} = 6[/tex]
18 is divisible by 3, so you can assume that the quotient will be an integer. (3*6 = 18, to check your answer)
(To know if something is divisible by three, add the numbers of the dividend. If they equal a number that can be divided by three, you can assume that you'll get an integer and whole number.
For example: 1 + 8 = 9, 3*3 = 9)
[tex]\sqrt{49} =7[/tex]
The square root of 49 is 7. If you've memorized your square roots, you could identify quickly that the square root would be an integer. If you haven't it's okay, keep working on it!
I hope this helps!
Write an equation for the trend line shown
Answer:
y= -x + 225
Step-by-step explanation:
it has a negative slope so -x
it crosses the y axis at (0,225)

What was the first error that Andrea made?
O Andrea used the reciprocal of the slope.
Andrea made a computational error when she simplified m.
Andrea substituted incorrectly when she solved for b.
Andrea made a sign error when she solved for b.
Answer:
B.
Step-by-step explanation:
Can someone help me, please. :(
Answer:
The answer is C.
Step-by-step explanation:
It cannot be between 3 and 4 because 2/3 is less than 1. You cannot end up with a larger number than 3 in this case. Similarly, it cannot be less than 2/3 because you are multiplying it by 3, which is larger than your first number.
Therefore, it has to be between 3 and 2/3 because you are taking two thirds of 3, which is 2.

A farmer says that for every row of tomato seeds he plants, he can harvest 6.5 bushels of tomatoes. The farmer needs to harvest at least 52 bushels of tomatoes. What is the least number of rows of tomato seeds that the farmer will need to plant?
Answer:
8 rows
Step-by-step explanation:
The answer is 8 because 52 divided by 6.5 is 8
The least number of rows of tomato seeds that the farmer needs to plant is 8 row.
Given that, a farmer says that for every row of tomato seeds he plants, he can harvest 6.5 bushels of tomatoes.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
The farmer needs to harvest at least 52 bushels of tomatoes.
The number of rows of tomato seeds need to plant = 52/6.5
= 8
Therefore, the least number of rows of tomato seeds that the farmer needs to plant is 8 row.

Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1 3/5 doors. How many liters of paint are needed for 1 door? Draw a diagram to represent the situation, then find the answer.
Answer: 6
Step-by-step explanation: i know this it's hard to explain
It will take 1 3/4 gallons to paint the whole fence.
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find the expression of 3/4 divided by 1/8
3/4 x 8= 6
Therefore, The value of 7.89 divided by 2 is; 3.945
Now consider the gallons to paint the whole fence be x
1 1/4/x = 5/7
1.25/x = 5/7
then Cross multiply;
(5 × x) = (1.25 × 7)
5x = 8.75
x = 8.75/5
x = 1.75 = 1 3/4 gallons

I need help pleasssssseeeeeeeeeeeeeeeee
Answer:
Reflect across BC
Translate 4 units right
Translate 1 units down
Step-by-step explanation:
In order to receive DEF, you need to flip it across line BC. In order to find this out, just test what would happen if you flipped on the other sides. If you did that correctly, the other sides wouldn't be shaped the same as DEF.
Remember, translation is moving the ENTIRE triangle. Not just one particular point. In order to line up the two shapes correctly, you have to move the shape down one unit and across four units. To find this, you can simply just count it out. Remember, C has to reach to F. B has to reach to E. And A has to reach to D. Once you find how much you translate the graph, then you've found the answer.
