Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 4 h, and Car B traveled the dista
poizon [28]
The rate of Car A is x
The rate of Car B is x - 5

They travel the same distance. So we can make an equation:

4(x) = 4.5(x-5)

Solve for x.

4(x) = 4.5(x-5)
4x = 4.5x - 22.5

Subtract 4.5x on both sides

-0.5x = -22.5

Divide by -0.5 on both sides
x = 45

But we want the speed of Car B which is x - 5

So Car B's speed is 45 - 5 = 40

Your answer is 40

In your computation, approximate its value as 3.14.
andrey2020 [161]

Answer: d

Step-by-step explanation:

Find the area of the rectangle.

A=l*w\\A=(15in)(12in)\\A=180in^2

Find the area of the base of the semicircle.

A=\pi r^2

12 in would be the diameter, divide by 2 to get the radius.

\frac{12}{2}=6

Plug this into the formula.

A=(3.14)(6)^2\\A=113.04in^2

Since we do not have a full circle but a semi one instead, we must divide our result by 2.

\frac{113.04}{2}=56.52in^2

Add both areas.

180+56.52=236.52in^2

If 3 is added to a certain number, the results is 15 less than three times the number. Find the number
Harman [31]

Answer:

number = 9

Step-by-step explanation:

number = x

3 is added to a number = (x+3) result

3 times the number = 3x

15 less than three times the number = 3x-15

the results is 15 less than three times the number

x+3 = 3x -15

3x-x= 3+15

2x = 18

x=9

Solve the following 2 + 8 ÷ 2 x 3
mafiozo [28]

Answer:

<h2>14</h2>

Step-by-step explanation:

Solution,

Use the BODMAS Rule:

B = Bracket

O = Of

D = Division

M= Multiplication

A = Addition

S = Subtraction

Now,

Let's solve,

2 + 8  \div 2 \times 3

First we have to divide 8 by 2

= 2 + 4 \times 3

Calculate the product

= 2 + 12

Calculate the sum

= 14

Hope this helps...

Good luck on your assignment..

Can you show the working out as well please?​
Airida [17]

Answer:

BC = 60

Step-by-step explanation:

3X + X = 80      <---- X = BC

3X + X = 4X

4X = 80   <---- DIVIDE BOTH SIDES BY 4

4X ÷ 4 = X

80 ÷ 4 = 20

20 × 3 = 60
