Beth and joe won first place at the local talent show and shared the 50$ price equally they also gave some money to their friend

If they each kept the same amount of the $50 prize, then we divide $50 by 2 people, giving each of them $25 winnings. Your question is then a little confusing because it could be answered in two ways. Did they each keep $20.75 out of their $25 winnings, or did the two of them keep $20.75 in a combined total? Please read your question again to see which might be the case. I'm answering on the assumption that they each kept $20.75.

STEP 1:
divide total prize money by 2

= $50 ÷ 2
= $25 each won

STEP 2:
If they each kept $20.75

= $25 won - $20.75 each kept
= $4.25 each gave away

STEP 3:
multiply amount given away by 2 people
= $4.25 * 2 people
= $8.50 total given away

ANSWER: The total given to Romy is $8.50.

Hope this helps! :)

Answer:

1.) 9.2

2.)

625

633

the dealer

8.81

Step-by-step explanation:

I'm gonna assume that cm= compounded monthly

1.)

effective rate: .153/12= .01275

x= payments

$2590.67=300*\frac{1-(1+.01275)^{-x}}{.01275}\\.110103476=1-1.01275^{-x}\\.889896525=1.01275^{-x}\\\log_{1.01275}.889896525=-x\\x=9.207$

2.)

If there is no interest rate attached to financing through the deal the payment is just

37500/60 = 625

The monthly payment from the bank has a present value of 37500-3000=34500

and the effective rate is .039/12= .00325

$34500=x\frac{1-(1.00325)^{-60}}{.00325}\\34500=54.43234738x\\x=633.81$

Finally, the amount we save is just the difference

633.81-625=8.81

Find the value of each variable in the parallelogram

wlad13 [49]

Answer:

B= 90

C= 80

D= 100

Step-by-step explanation:

So let’s start with the bottom angles.

We know that the adjacent angles in a parallelogram add up to 180° so our equation would be $(b-10) + (b+10)=180$ . So let’s simplify it b and b are both the same variables so we will get 2b and -10 + 10 is 0 so we get the following equation $2b=180$ .

So now we divide 180 and 2 and we get 90 as b.

So one side will be 100 because of the +10 and the other 90 because of the -10.

Now for the next side.

$d+c=180$

So we know that b+10 is adjacent to c so 180-100 is 80, so 80 is c.

Now for d.

b-10 is 80 so 180-80 is 100, so d is 100.
