Answer:
x = 12
Step-by-step explanation:
The 2 given angles form a straight angle and are supplementary, thus
10x - 20 + 6x + 8 = 180
16x - 12 = 180 ( add 12 to both sides )
16x = 192 ( divide both sides by 16 )
x = 12
Answer:
Step-by-step explanation:
First find the slope(m) between (0,-5) and (-5,-6)
m = = = =
y = x -5
I attached the graph. I used desmos.
Hope that helps!
Answer: (3,5)
Step-by-step explanation:
y=3x-4
2x-3y=-9
2x-3(3x-4)=-9
2x-9x+12=-9
7x=21
x=3
y=3(3)-4
y=5
Answer:
Width = 5
Length = 10
Step-by-step explanation:
Let x be the width of the rectangle
2x + 2(2x) = 30
x = 5
Width = 5
Length = 10
x = the number of people
8x + 120 = 320
[they charge $8 for each person(x) plus a fee of $120, and the total amount of money you have is $320]
Your answer is A
