Answer:

40

Step-by-step explanation:

If Whitney was driving x speed, her mother was driving x+5. Multiply that by the distance each traveled, and you have an equation that looks like this:

8(x+5) = 7(x)

Simplify it and you get:

8x + 40 = 7x

Now solve regularly:

8x-8x + 40 = 8x - 7x

40 = 1x

40 = x

Whitney's speed: 40

Her mother's speed: 45

Answer:

a taco is 1.25 and a drink is 0.95

Step-by-step explanation:

tacos = t

drinks = d

5t + 3d = 9.10

3t + d = 4.70

this is a simultaneous equation so times the first one by one and the second by 3 and then take them away from each other and solving to get

t = 1.25 and d=0.95

one drink is $0.95

one taco is $1.25

Hope this helps!!

What does c equal in thus equation I don't know for the life of me help is deeply appreciated 4(3+c)+c=c+4
Shkiper50 [21]

Answer:

-2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4(3+c)+c=c+4

(4)(3)+(4)(c)+c=c+4(Distribute)

12+4c+c=c+4

(4c+c)+(12)=c+4(Combine Like Terms)

5c+12=c+4

5c+12=c+4

Step 2: Subtract c from both sides.

5c+12−c=c+4−c

4c+12=4

Step 3: Subtract 12 from both sides.

4c+12−12=4−12

4c=−8

Step 4: Divide both sides by 4.

4c

4

=

−8

4

c=−2

what's the final volume of a gas with an initial volume of 75ml if the pressure decreases from 300ml to 200ml? A. 50.0ml B.112.5
aivan3 [116]
300 ml ... 200 ml
75 ml ... x = ?

If you would like to know what is the final volume of a gas, you can calculate this using the following steps:

300 * x = 200 * 75     /300
x = 200 * 75 / 300
x = 50.0 ml

The correct result would be A. 50.0 ml.
