<span>8 - 2b = -2/3(12b + 6)
8 - 2b = -8b -4
8 + 4 = -8b + 2b
12 = -6b
b = -12/6
b = -2
So, your final answer is b = -2</span>
Answer:

Step-by-step explanation:
we have the expression

Convert to vertex form

where
a is the leading coefficient
(h,k) is the vertex
Complete the square


Rewrite as perfect squares

so
The coefficient a =1
The vertex is the point (-2,-2)

Answer:
43.5 % decrease
Step-by-step explanation:
Take the original price and subtract the new price
850-480
370
Divide by the original price
370/850
.435294118
Change to percent form by multiplying by 100
43.5294118 % decrease
43.5 % decrease
Answer:
The answer is 61.4 L
Step-by-step explanation:
Using the formula of cuboid, V = l×b×h, to find the total amount of water contained :
l = 120cm
b = 40cm
h = 15cm
V = 15×120×40
= 72 000cm³
= 72 L
It is given that she uses 10.6L for shower. Then calculate the remaining water by substracting 10.6L from the original amount of water :
remaining = 72 - 10.6
= 61.4 L
