Answer:
2000 linear feet
becouse 21-19=2 so thats his profit per linear foot
and it costs him 4000 so to get that amount he has to sell 2000 because 2000×2=4000
Answer:
Sandra need to score at least <u>56%</u> in her fifth test so that her average is 80%.
Step-by-step explanation:
Given:
First 4 test scores = 87%, 92%, 76%,89%
Average targeted = 80%
We need to find the minimum score she needs to make on fifth test to achieve average of at least 80%.
Solution:
Let the minimum score she needs to make in fifth test be 'x'.
Total number of test = 5
Now we know that;
Average is equal to sum of all the scores in the test divided by number of test.
framing in equation form we get;
Multiplying both side by 5 we get;
Subtracting both side by 344 we get;
Hence Sandra need to score at least <u>56%</u> in her fifth test so that her average is 80%.
Answer:
2nd choice is correct.
Step-by-step explanation:
We need to find about which polynomial is represented by the algebra tiles.
so we just need to collect all terms written on tiles then combine them.
Notice that - means -1 and + means +1
Row wise terms are:
Now combine like terms:
Hence 2nd choice is correct.
<u><em>Answer: y=27 and 27=y *The answer should be positive sign.*</em></u>
Step-by-step explanation:
multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.
a*c=b*c
division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.
a/c=b/c for c≠0
multiply by 3 both sides of an equation.
3*2/3y=18*3
simplify.
18*3=54
2y=54
divide by 2 both sides of an equation.
2y/2=54/2
simplify by equation.
54/2=27
27*2=54
54/27=2
2*27=54
y=27
Hope this helps!
Thanks!
Have a great day!
The decimal form would be 5.29150262
