Answer:
16, 74
Step-by-step explanation:
3x +10 + 12x +50 = 90
15x + 60 = 90
15x = 90 -60
15x = 30
x = 30/15
x = 2
3x + 10 = 3*2 +10 = 6 +10 = 16
12x + 50 = 12*2 +50 = 24 + 50 = 74
The slope of a line is given by the ratio of the rise to the run of the line.
The value of, y is <u>4</u>
Reasons:
The given points on the line are; (-4, y), and (5, 7)
The slope of the line, = 
Required:
To find the value of <em>y</em>
<em />
Solution:
The formula for the slope is given as follows;
Where;
(x₁, y₁) = (-4, y)
(x₂, y₂) = (5, 7)
Which gives;
3·(7 - y) = 1·(5 + 4) = 9
21 - 3·y = 9
3·y = 21 - 9 = 12
The value of, y = <u>4</u>

Answer:
A.
Jada should have multiplied both sides of the equation by 108.
Step-by-step explanation:
-4/9=x/108
you must multiply both sides
108*-4/9 = x*108
=-9/4
Answer:
Area of Tamara room
=9556 square feet
Width
=813 feet
Length= 11.75 feet
Total area= 19794 square feet
480 square feet will not be enough
Step-by-step explanation:
Dimensions of Tamara's room to the nearest whole numbers
Area of Tamara room
=9556 square feet
Width
=813 feet
For the length
Length*width= area
Length= area/width
Length= 9556/813
Length= 11.75
To the nearest whole number = 12 feet
The ceiling is 12 feet high
Let's calculate for the area of the combination
1)Height and width two times
2)Height and length two times
1).area = 12*813
= 9756
Then 9756*2= 19512
2). area= 12*11.75
= 141
Then 141*2= 282
Total area = 282+19512
Total area= 19794
