Answer:
its 78
Step-by-step explanation:
The unit rate in the equation is 20.
Option C) is the correct answer.
<u>Step-by-step explanation</u>:
Step 1 :
In the given equation y = 20x
where,
x ⇒ total number of hours for tutoring
20 ⇒ the cost per hour of tutoring
y ⇒ the total cost for total hours of tutoring
Step 2 :
Unit rate refers to the value per hour.
Here, the cost for 1 hour of tutoring is $20.
∴ The unit rate is $20 per hour of tutoring.
Answer:
x > -1 or x < -1
Step-by-step explanation:
For the first equation, 5x-29 > -3
Step 1: Move the constant to the right and change its sign
5x-29 > -34
5x > -34+29
Step 2: Calculate the sum
5x > -34+29
5x > -5
Step 3: Divide both sides of the inequality by <em>5</em>
5x > -5
x > -1
<em><u>Answer</u></em><em><u>:</u></em> -1
For the second equation, 2x+31 < 29
Step 1: Move constant to the right and change its sign
2x+31 < 29
2x < 29-31
Step 2: Calculate the difference
2x < 29-31
2x < -2
Step 3: Divide both sides of the inequality by 2
2x < -2
x < -1
<em><u>Answer</u></em><em><u>:</u></em> x < -1
Answer:
The answer will be: C: 2<em>t </em>+ 10
Step-by-step explanation:
You can check the answer by replacing <em>t </em>with any number.
Example:
I want to find the perimeter for 3 triangles. Here's how I would write the equation.
2(3) + 10 = 6 + 10 = 16
We can check by adding all the sides for three triangles.
2 + 2 + 2 + 5 + 5 = 16
Hope this helped :)
From second equation y = 8 - x so
7x + 2(8 - x) = -14
5x = -14 - 16 = -30
x = -6
and y = 8 - -6 = 14
Answer x=-6,y=14
