metal remaining. The equation 8.2x - 2.3x = 177 represents how much sheet metal is remaining and
the cost of the remaining amount. How much does sheet metal cost per square foot?
Sheet metal costs $ per square foot.
ANSWER=30
because if you 8.2-2.3 you get 5.9 and if you divide by 177 it is 30
hope it helps
Rewrite the function f(x)=4(x-2)²-8 in the form f(x)=ax²+bx+c.
Answer:
lma ooo how many times did you post
4x^2 - 16x + 8
Step-by-step explanation:
4(x-2)^2-8
4(x-2)(x-2)-8
4{x^2-4x+4}-8
4x^2 - 16x +16 - 8
4x^2 - 16x + 8
Three years ago, claire borrowed money from her father to pay for a class trip. She agreed to pay him 6% simple annual interest on the loan. Now she owes him 90$ in interest, plus the principal amount. How much did Clare borrow? The answer is 500, but how did you get that answer correctly? Step by step can u show me?
Answer:
Below
Step-by-step explanation:
6% simple annual interest on the loan for 3 years so 6x3=18
So the interest of the whole amount is 18%, so now you got to find what of 18% is 90
This looks like (initial amount)x(number)%=(final amount)
x=initial amount
number%=18
final amount=90
All percentages are just number%/100. So we have either 18/100, or .18 depending on how you want to work it.
So now we do 90÷0.18 which gives you the answer 500
can u help pretty pls and fast thank you

A principal of $2900 is invested at 6.25% interest, compounded annually. How much will the investment be worth after 14 years?
Answer:
$6774.4
Step-by-step explanation:
Given data
P=$2900
r= 6.25%
t= 14 years
A=???
The compound interest formula is given as
A=P(1+r)^t
substiute
A= 2900(1+0.0625)^14
A= 2900(1.0625)^14
A= 2900*2.336
A= $6774.4
Hence the final amount is $6774.4
What is the slope of this line?
(sorry for the quality.)
Answer:
slope = - 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 8,6) and (x₂, y₂ ) = (0, - 2) ← 2 points on the line
m = [tex]\frac{-2-6}{0+8}[/tex] = [tex]\frac{-8}{8}[/tex] = - 1
Solve 4+x/7=2 50 points

-7.2 as a mixed number.
Answer:
7 1/5
Explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
7.2=7.2/1
Multiply to remove 1 decimal places. Here, you multiply top and bottom by 10^1 = 10
7.2/1×10/10=72/10
Find the Greatest Common Factor (GCF) of 72 and 10, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 2,
7/2÷2/10÷2=36/5
Simplify the improper fraction,
=7 1/5
In conclusion,
−7.2=−7 1/5
Hope it helped. :)

Step-by-step explanation:
Carlos has 2 dollars more than half of the total amount of money his brother has. If x represents the amount of money Carlos's brother has, which expression can be used to represent this situation?
Answer:
[tex]y = 2 + \frac{1}{2}x[/tex]
Step-by-step explanation:
Given
Represent Carlos with y and his brother with x.
Analysing the statement one after the other:
Half of his brother's amount is: [tex]\frac{1}{2}x[/tex]
$2 more: means we add 2 to [tex]\frac{1}{2}x[/tex]
So, we have: [tex]2 + \frac{1}{2}x[/tex]
The above represent Carlos's amount.
So, the expression is:
[tex]y = 2 + \frac{1}{2}x[/tex]

A tree in leilas backyard has been growing for 3 1/5 years. It is 3/4 meters tall how many meters per year?
Answer:
The tree grew 15/64 meters per year.
Step-by-step explanation:
Given
Length of a tree = 3/4 metersTotal time taken by the tree to grow 3/4 taller = 3 1/5 or 16/5 yearsTo determine
Per year growth of the tree in meters
Per year growth of the tree in meters can be determined by dividing the total length of a tree i.e. 3/4 meters by the total time taken by the tree to get 3/4 taller.
Per year growth of tree = Total Length / Total time to grow
= 3/4 ÷ 16/5
= 3/4 × 5/16
= [3×5] / [4×16]
= 15/64 meters
Therefore, the tree grew 15/64 meters per year.

what does x equal in this equation -5x + 8 = -2
Answer:
x = 2
Step-by-step explanation:
-5x + 8 = -2
-5x + 8 - 8 = -2 -8
-5x = -10
-5x/5 = -10/5
-x = -2
x=2
Simplify the equation:
-5x = 2 + 8
-5x = 10
x = -2
