Step-by-step explanation:
17) 3x+5-12+4x+2x
3x+4x+2x +5-12
8x-7
if x =6
8*6-7 =48-7
= 41
18.) 9(3x-4y+8)
27x-36y+72
First lets convert the pints to cups.
1 pint = 2 cups
12 pints = ? cups
Now lets multiply to find out how many cups are in 12 pints.
12 × 2 = 24
24 cups in 12 pints.
Now lets look at the information we have.
4 cups of water per 9 servings
Now lets divide to see how many time 24 goes into 4.
24 ÷ 4 = 6
Now lets multiply:-
6 × 9 = 54
So, 54 servings of water fir in 12 pints of water.
Hope I helped ya!!!
20/10 is same as 20:10 so the whole number is 2
You have the value for y, so you substitute that equation for y, times three because there are three yS.
So you have: 2x + 3y = 10
2x + 3 x 2x + 4 or 2x + 3(3x + 4)
so the answer would be B, 2x + 3(3x + 4)
