Zach and Ginny are building model cars. Ginny's car is 2 more than 3 times the length of Zach's car. The sum of the lengths of both cars is 30 inches. Write an equation to determine the lengths of Zach's and Ginny's cars.
3x + 2 = 30
x + 2 + 3x = 30
2x + 3 = 30
x + 2x + 3 = 30

Answers

Answer:

x + 2 + 3x = 30

Step-by-step explanation:

Both lengths are unknown, but Ginny's car length is described in terms of Zach's car length, so we choose a variable for Zach's car length.

Let x = Zach's car length.

Zach's car length is x.

"Ginny's car is 2 more than 3 times the length of Zach's car."

Ginny's car length is 2 + 3x.

Add the lengths:

x + 2 + 3x

"The sum of the lengths of both cars is 30 inches."

x + 2 + 3x = 30

Answer: x + 2 + 3x = 30

Point A is located at -0.75 and point B is located at 0.25 on a number line. Which expression shows how to find the distance between points A and B?

A. |–0.75| – 0.25

B. |–0.75 + 0.25|

C. |–0.75 – 0.25|

D. |0.75 – 0.25|













Answers

Answer:

Should be C sorry if not

Step-by-step explanation:

When I do the math in my head I take the distance between 0.75 and 0 and the distance between 0.25 and 0 and add them together giving me the distance between the two points. To get that distance you would subtract the two numbers from each other with the absolute value brackets on the outside of the equation so it will not make the negative a positive. If the negative is a positive, it would make it 0.50 which would be incorrect. The distance between the two points here would be 1.0 if that was the equation. That is a way I used to figure out equations like this when I was younger. Take it for what it is worth.

Let the unknown side be x

4 : 5 : x = 36 : 45 : 63

Divide LHS by 9

4 : 5 : x = 4 : 5 : 7

Since you may see x and 7 are same. So, the missing side is 7.

Answer:

Step-by-step explanation:

[tex]\frac{AB}{PQ} = \frac{BC}{QR}[/tex]                      #1 Find same sides  

So, [tex]\frac{4}{36} =\frac{BC}{63}[/tex]                 #2 fill it in.

36BC= 252                 #3 Cross multiply.

[tex]\frac{36BC}{36}[/tex]= [tex]\frac{252}{36}[/tex]                      #4 Divide by 36

BC= 7                           #5 Here's your answer!

If you want to check, plug the sides in.

[tex]\frac{4}{36} =\frac{5}{45} =\frac{7}{36}[/tex]

Once the first three spots are filled, you’re left with only one choice for the last spot.

Step-by-step explanation:

[tex] \frac{2}{25} \times \frac{10}{11} [/tex]

[tex] \frac{2}{5} \times \frac{2}{11} = \frac{2 \times 2}{5 \times 11} [/tex]

The given information is,

Let's find the required solution,
