It is systems of equations.
Let cups=c and l=liters
7c + 3l = 9.8
<span>5l - 9c = 6 </span>
<span>35c + 15l = 49 </span>
<span>15l - 27c = 18 </span>
<span>62c = 31 </span>
<span>c = 1/2 pint </span>
<span>l = 2.1 pint </span>
<span>1 cup = 1/2 pint 1 liter = 2.1 pints</span>
Answer:
x = -4
Step-by-step explanation:
8x = 8 + 2(x-10) + 3x
simplify
8x = 8 + 2x - 20 + 3x
simplify again
8x = 5x - 12
subtract 5x from both sides
3x = -12
divide both sides by 4
x = -4

Step-by-step explanation:
Let Amara money be represented by a
Since Candace has $15 more than Amar. Therefore, Candace money will be = a + 15
Their total money will be 85 and this can be represented in an equation as:
a + (a + 15) = 85.
a + a + 15 = 85
2a + 15 = 85
2a = 85 - 15
2a = 70
a = 35
Amar money = $35
Candace money = $35 + $15 = $50
No they don't. 2/3=.67, 3/4=.75. 8-.75=7.25. 7.25/.67=10.82.... 87/8=10.88 :) hope this helps
