For number 6, Tom's unit rate was 0.1254 per meter. Samma's unit rate 0.1299 per meter. So Samma had a faster unit rate by 0.0045.
For number 8:
$10.45 ÷ 5 = $2.90
So the unit rate is $2.90.
Hope this helps. :)
There are an infinite number of solutions given the information you provided. For every real value of x there will be a corresponding real value of y.
y=5x+7 Has not restriction upon the domain or range...
What is the value of y? 5x+7
Answer:
The Answer is 3 - sqrt7
Step-by-step explanation:
2/3 + sqrt7 the starting equation
You multiply it by the conjugate which is 3 - sqrt7
= 2(3 - sqrt7) / (3 + sqrt7) (3 - sqrt7) the equation after you multiply by 3 - sqrt7
(3 + sqrt7) (3 - sqrt7) = 2
= 2(3 - sqrt7) / 2 the equation after you simplify (3 + sqrt7) (3 - sqrt7)
Divide out the 2's
= 3 - sqrt7/1 the equation after you divide out the 2's
= 3 - sqrt7 is THE ANSWER
The answer is y=(1/20)x^2
It will cost $33.
Since wood cost $ .60 sq ft, you can assume she needs to buy 55 sq ft because she will need to buy enough to have 54.3 square ft.
55 x $ .60 = $33
$32.58 would be he total for the 54.3 sq ft and .42 cents would be for the left over .7 sq ft that she didn’t use
