Answer:
last test grade=x x ≥ 79 so 79%
Step-by-step explanation:
(84/5)+(88/5)+(95/5)+(104/5)+(x/5) ≥ 90
Simplify: (371/5)+(x/5) ≥ 90
Subtract (371/5) from both sides
Then you have (x/5) ≥ (79/5)
Then multiply both sides by 5 and you have x ≥ 79

14. 9(y - 4) - 7y = 5(3y - 2
step by step please
Answer:
y=-2
Step-by-step explanation:
9(y−4)−7y=5(3y−2)
(9)(y)+(9)(−4)+−7y=(5)(3y)+(5)(−2)
9y+−36+−7y=15y+−10
(9y+−7y)+(−36)=15y−10
2y+−36=15y−10
2y−36=15y−10
Step 2:
2y−36−15y=15y−10−15y
−13y−36=−10
Step 3:
−13y−36+36=−10+36
−13y=26

y=-2
Answer:
y=-2
Step-by-step explanation:
Simplifying
9(y + -4) + -7y = 5(3y + -2)
Reorder the terms:
9(-4 + y) + -7y = 5(3y + -2)
(-4 * 9 + y * 9) + -7y = 5(3y + -2)
(-36 + 9y) + -7y = 5(3y + -2)
Combine like terms: 9y + -7y = 2y
-36 + 2y = 5(3y + -2)
Reorder the terms:
-36 + 2y = 5(-2 + 3y)
-36 + 2y = (-2 * 5 + 3y * 5)
-36 + 2y = (-10 + 15y)
Solving
-36 + 2y = -10 + 15y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-15y' to each side of the equation.
-36 + 2y + -15y = -10 + 15y + -15y
Combine like terms: 2y + -15y = -13y
-36 + -13y = -10 + 15y + -15y
Combine like terms: 15y + -15y = 0
-36 + -13y = -10 + 0
-36 + -13y = -10
Add '36' to each side of the equation.
-36 + 36 + -13y = -10 + 36
Combine like terms: -36 + 36 = 0
0 + -13y = -10 + 36
-13y = -10 + 36
Combine like terms: -10 + 36 = 26
-13y = 26
Divide each side by '-13'.
y = -2
Simplifying
y = -2

A function is given. g(x) = 4 x + 7 ; x = 0, x = h (a) Determine the net change between the given values of the variable. Incorrect: Your answer is incorrect. (b) Determine the average rate of change between the given values of the variable. Incorrect: Your answer is incorrect.
Answer:
4hStep-by-step explanation:
We are expected to solve for the change given the following values of x
0,h
so we substitute x= 0 and x=h in the given expression, get the result, and subtract the results from each other
for x=0
[tex]g(x) = 4 x + 7\\\\g(0)=4(0)+7\\\\g(0)=0+7\\\\g(0)=7[/tex]
for x=h
[tex]g(x) = 4 x + 7\\\\ g(h)=4(0)+7 \\\\g(h)=4h+7 \\\\g(h)=4h+7[/tex]
The change would be
[tex]g(h)-g(0)= (4h+7)-7\\\\g(h)-g(0)= 4h+7-7\\\\g(h)-g(0)= 4h[/tex]

One number is 13 more than the product of 9 and another number. If the sum of the two numbers is 103, find the two numbers.
Answer:
x + y = 103 Subtract 2nd from 1st EQ
-10y = -90
y = 9 and x = 94 9%2A9%2B13
and...checking
sum = 103
Step-by-step explanation:
The two numbers are 9 and 94.
What are simultaneous equations?In mathematics, a set of simultaneous equation, also known as a system of equations or an equation system, is a set of equations for which common solutions are sought.
Let the two numbers be x and y.
Then according to question,One number is 13 more than the product of 9 and another number we have ,
13 + 9x = y
or,9x - y = -13...(i)
Also,the sum of the two numbers is 103. So we have,
x + y = 103 ...(ii)
Adding equation (i) and (ii) we get,
10x = 90
or, x = 9
Put the value of x in equation (ii), we get
9 + y = 103
or, y = 103 - 9
or, y = 94
Hence the two numbers are 9 and 94.

Tom worked 48 hours last week and gets time-and-a-half pay for overtime. His regular pay is $32 per hour. a) How much does he make for an hour of overtime?
Answer:
$48
Step-by-step explanation:
From the question we know that;
His regular pay is $32 per hour.
Tom worked 48 hours last week and gets time-and-a-half pay for overtime.
Time and a half pay = 1.5
Hence, if Tom works for an hour of overtime, his pay for his overtime is calculated as:
= 1.5 × $32 × 1
= $48
Therefore, he was paid $48 for one hour of overtime.
Point V lies between points U and W on line UW. The distance between U and V is 2x-4, and the distance between V and W is 4x+10. If UW = 9x – 9, what is UW in units?
Answer:
36UNITS
Step-by-step explanation:
If point V lies between U and W, then UV+VW = UW
given parameters
UV = 2x-4
VW = 4x+10
UW = 9x-9
Substituting the given functions in the formula first, we will have;
2x-4+4x+10 = 9x-9
6x+6 = 9x-9
Collect like terms
6x-9x = -9-6
-3x = -15
x = -15/-3
x = 5
Substitute x = 5 into UW.
Since UW = 9x-9
UW = 9(5)-9
UW = 45-9
UW = 36
