Answer:
Step-by-step explanation:
x = 3y.......(1)
x - 3y = 0 ....(2)
Substituting x in (1) into (2)
3y - 3y = 0

I got 25 (24.738634) sry if wrong
Answer:I think your Answer would be x=14 but I am not sure.
Step-by-step explanation:
2log 10 (x+86)=4
Determine the defined
2log 10 (x+86)=4,x >-86
Divide both sides by 2
log 10 (x+86)=2
Solve by converting the logarithm into exponential form
x+86=10 2
Evaluate the power
x+86=100
Move constant to the right
x=100-86
Subtract the numbers
x=14,x>-86
Check if the solution is in the defined range
SOLUTION
X=14
Step-by-step explanation:
For number 5 the answer would be <em>economy</em> because there is a <u>2 dollar difference</u> and the shampoo bottle has 20 more ounces then the <em>regular</em> bottle. The <u>2 dollar difference</u> changes the whole thing.
For number 6 the answer is still <em>economy</em> because you get more ounces in the bottle of shampoo for a <u>3 dollar difference</u> in the price.
