Answer:
x = 11
Step-by-step explanation:
distribute: 4x - 28 = 27 - x
add x to both sides: 5x - 28 = 27
add 28 to both sides: 5x = 55
divide 5 to both sides: x = 11
Answer:
y = 8(.88)^x
y = 4.221855 for the fifth reduction
Step-by-step explanation:
We can use the formula
y =ab^x
where a =the initial value
b= 1 -percent decrease
a = 8 inches
b = 1-12%
= 1-.12
= .88
y = 8 (.88)^x
The fifth reduction is
y = 8 (.88) ^5
y = 4.221855
1. ( t + 8) (t - 6) t = -8 and 6
2. prime
3. (t - 16) (t + 3) t = 16 and -3
4. prime
5. (t + 15) (t - 2) t = -15 and 2
Answer:
x=y/12
Step-by-step explanation:
I took the variable and flipped it. Instead of solving for y inches, I solved for x feet.
Answer:
Step-by-step explanation:
Short Answer: No
2(12 - y) = 23- (2y - 1) Remove the Brackets on both sides
24 - 2y = 23 - 2y + 1 Combine like terms on the right
24 - 2y = 24 - 2y No matter what you do, the 2ys are going to cancel. When they do, the question goes with them.
You get 24 = 24 Which is true but not relevant.
The other answer you could use is there are an infinite number of answers.
Equality will be maintained, but there is no single answer that works.
