Answer:

1.8 gallons would be used.

Step-by-step explanation:

TOTAL AREA TO BE PAINTED:

     2 x 10 x 20  +   2 x10x 16 = 720 ft2

720 ft2 / 400 ft2 /gal = 1.8 gal

Which expression is equivalent to 2 (t-4) +1. A 2t-5 B.2t-7 C. 2t-9 D. 2t -3
seraphim [82]

Answer: 2t + -8

Step-by-step explanation: Let's simplify this problem using the distributive property.

The first thing we want to do is change this minus to plus a negative.

Now we can distribute or multiply this 2 times

each of the terms inside the set of parentheses.

So we get 2(t) + 2(-4) and this simplifies to 2t + -8.

2t + -8 is the same thing as 2t -8.

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
swat32
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!  :)
