Answer:

b = 7

Step-by-step explanation:

108 = -2(-5 - 7b)

Distribute -2 to the terms inside the parenthesis:

108 = 10 + 14b

Subtract 10 from both sides of the equation to isolate 14b:

108 - 10 = 10 + 14b - 10

98 = 14b

Divide 14 on both sides of the equation to solve for b:

$\frac{98}{14} = \frac{14b}{14}$

7 = b

A store is having a sale on jelly beans and almonds. For 6 pounds of jelly beans and 2 pounds of almonds, the total cost is $12

CaHeK987 [17]

Solution:

Let each pond of jelly beans cost $x.

and each pond of almonds cost $y.

Then we can write

$6x+2y=12.......(i)$

$3x+5y=15.....(ii)$

Now solve these two equations together using substitution we get

$3x=15-5y$

$30-10y+2y=12\\
\\
-8y=12-30\\
\\
-8y=-18\\
\\
y=2.25\\
\\
3x=15-5y=15-5*2.25=3.75\\
\\
x=1.25$

Hence each pond of jelly bean cost 1.25$

Each pond of almond costs 2.25$
