Jordan drives for three hours at an average of 60 miles per hour what is the distance in miles he drives during that time
Answer:
d = 180 miles
Step-by-step explanation:
Given that,
The average speed of Jordan, v = 60 mph
Time, t = 3 hours
We need to find the distance he drives during that time. Average speed is equal to the distance divided by time taken.
v = d/t
[tex]d=v\times t\\\\d=60\times 3\\\\d=180\ \text{miles}[/tex]
So, the distance driven during that time is 180 miles.

It is Moesha's birthday. Her mom gives her $10, and her dad gives her $15. Moesha uses her gifts to buy a doll for $20.
Both expressions below represent how much money she has left.
Expression 1: $10+ $15 - $20
Expression 2: ($10+ $15) - $20
Why is expression 2 better than expression 1 in representing Moesha's situation?
A Expression 2 stresses that the doll could not be bought without parents' gifts.
B Expression 1 separates the money that Moesha got as gifts from the money that she spent.
C Expression 2 shows Moesha's parents gave her a doll.
D Expression 1 does not solve to the correct amount of money that Moesha has left.

What will be the return value of =SUM({10;15;20;25;30})?
Answer:
The return value is 100
Step-by-step explanation:
Given
[tex]=SUM({10;15;20;25;30})[/tex]
Required
Determine the return value
In Microsoft Office Excel, the sum of values is represented as:
[tex]=SUM({a_1;a_2;a_3;.....;a_n})[/tex]
This is interpreted as:
[tex]SUM= a_1;a_2+a_3+.....+a_n[/tex]
So, in the case of:
[tex]=SUM({10;15;20;25;30})[/tex]
The return value is:
[tex]Value= 10 + 15+ 20 + 25 + 30[/tex]
[tex]Value= 100[/tex]
Hence, the return value is 100

Find the solution to the system of equations: x + 3y = 7 and 2x + 4y = 8
1. Isolate x in the first equation:
2. Substitute the value for x into the second equation:
3. Solve for y:
4. Substitute y into either original equation:
5. Write the solution as an ordered pair:
x = 7 – 3y
2(7 – 3y) + 4y = 8
14 – 6y + 4y = 8
14 – 2y = 8
–2y = –6
y = 3
x + 3(3) = 7
(, )
Answer:
The solution to the system of equation is: (-2,3)
Step-by-step explanation:
We need to find the solution to the system of equations: x + 3y = 7 and 2x + 4y = 8
I am placing steps for each point given
1. Isolate x in the first equation:
First equation is:
x+3y=7
Isolating x:
x=7-3y
2. Substitute the value for x into the second equation:
Second equation is:
2x+4y=8
Putting value of x: x=7-3y
2(7-3y)+4y=8
3. Solve for y:
2(7-3y)+4y=8
Multiply 2 with terms inside the bracket
14-6y+4y=8
-2y=8-14
-2y=-6
y=-6/-2
y=3
So, we get value of y: y=3
4. Substitute y into either original equation:
Putting value of y: y=3 in equation 1
x+3y=7
x+3(3)=7
x+9=7
x=7-9
x=-2
So, we get value of x: x=-2
5. Write the solution as an ordered pair:
After solving the equation we get:
x = -2 and y = 3
The ordered pair is: (-2,3)
Answer:
-2,3
Step-by-step explanation:
Isolate x in the first equation:
Substitute the value for x into the second equation:
Solve for y

Answer:
x= -14
Step-by-step explanation:
-x+8+3x=x-6
2x+8=x-6
2x-x=-6-8
x= -14
The value of x in the equation is -14
How to solve the equation?We have:
-x+8+3x=x-6
Collect like terms
3x - x - x = -6 - 8
Evaluate the like terms
x = -14
Hence, the value of x in the equation is -14

Consider all seven-digit numbers that can be created from the digits 0-9 where the first and last digits must be even and no digit can repeat. Assume that numbers can start with 0. What is the probability of choosing a random number that starts with 4 from this group
Answer:
[tex]P_4= 0.2[/tex]
Step-by-step explanation:
From the question we are told that
Consider all seven-digit numbers
Created from the digits 0-9
Generally number of digits that starts with 6 is mathematically given as
The total amount of digits from 0-9(0,1,2,3,4,5,6,7,8,9 = 10
The total amount of even digits within 0-9 (0,2,4,6,8) = 5
The total amount of 3-digit numbers giving the first and last digits to be even = 5 * 10 * 5 = 250
The total 3-digit numbers giving the first digit is 4 and last digit is even = 1 * 10 * 5 = 50
Probability the number starts with 4
[tex]P_4 = \frac{50}{250}[/tex]
[tex]P_4= 0.2[/tex]
I need help with This one
Answer:
1 and 2
Step-by-step explanation:
If y was 1: -2 x 1 + 18 = -2 + 18
= 16 This works
If y was 2: -2 x 2 + 18 = -4 + 18
= 14 This works
If y was 3: -2 x 3 + 18 = -6 + 18
= 12 This does not work since -2y + 18 has to be greater than 12.

Work out the size of angle x.
47°
Answer:
133 degrees
Step-by-step explanation:
The angle 47 degrees is on a straight line, and the angles on a straight line add up to 180 degrees.
So, to find the angle parallel to 47 degrees, subtract 47 degrees from 180 degrees
180 - 47 = 133 degrees
Now, the relationship between the angle that is 133 degrees and the angle of x is that they are corresponding angles.
And corresponding anglea are the same.
Thereforw, x = 133 degrees
