Need help for 16) and 19) Solve each equation and check. Show all work please

Paladinen [302]

Step-by-step explanation:

You said the other one would be the last haha just kidding I'm glad to help.

16. $\frac{k}{2}=(-5)^2$

First, get rid of that parenthesis.

$\frac{k}{2}=25$

Now multiply both sides by 2 so that you can isolate k

$2(\frac{k}{2})=25*2$

$k=50$

19. $\frac{r}{3}=\frac{121}{11}$

This is a pretty easy one. If you didn't know, 121/11 is actually 11 :)

$\frac{r}{3}=11$

Simply multiply by 3 to isolate r :)

$3(\frac{r}{3})=11*3$

$r=33$

What is the first step to solve the equation the equation 19 - 7h = 63?

dusya [7]

Answer:

Subtract 63 from both sides

Step-by-step explanation:

we always have to try to clear the incognita that in this case is going to be h

First we

Subtract 63 from both sides

then

Divide by -7 on both sides

19 - 7h = 63

19 - 7h - 19 = 63 - 19

- 7h = 44

-7h/-7 = 44/-7

h = -44/7

Person A can make a cupcake in 5 minutes, Person B can make a cupcake in 9 minutes. In total they made 168 cupcakes. How many cu

Stolb23 [73]

Answer:

Person A made 108 cupcakes and person B made 60 cupcakes.

Step-by-step explanation:

Person A makes 1 cupcake in 5 minutes.

Say in x minutes A makes : $\frac{x}{5}$ cupcakes

Person B makes 1 cupcake in 9 minutes.

Say in x minutes B makes : $\frac{x}{9}$ cupcakes

Total cupcakes prepared by A and B in x minutes = 168

$\frac{x}{5}+\frac{x}{9}=168$

$\frac{14x}{45}=168$

$x=\frac{168\times 45}{14}=540$

So, cupcakes made by A = $\frac{540}{5}=108$

Cupcakes made by B = $\frac{540}{9}=60$

Person A made 108 cupcakes and person B made 60 cupcakes.

11. Justin needs to rent a car to go on vacation. EnvoCar charges $65 and $0.10 per mile. FreedomRide charges $80 and $0.05 per

Keith_Richards [23]

$envo \: car = 65 + 0.10(m)$

$freedom \: ride = 80 + 0.05(m)$

I honestly don't know how to do a)

$envo \: car = 65 + 0.10(250) = 90.00$

$freedom \: ride = 80 + 0.05(250) = 92.50$

He should rent from Envo Car because it would be cheaper.
