Equation for length:
l = 3w
l × w = 12
Substitute 3w into L.
(3w) × w = 12
4w = 12
w = 3
Substitute 3 into w to find the length.
l = 3w
l = 3×3
l = 9
The width is 3 and the length is 9.
Answer:
58 miles per hour
Step-by-step explanation:
divide 696 by 12 and you get 58
Answer:
(9,36)
Step-by-step explanation:
Substitute the 4x for the y in second equation.
Basically setting them equal to each other because the both have 'y='
4x = 8x - 36
-4x = -36 (subtract 8x from both sides)
x = 9 (divide by -4, both sides)
y = 4(9) (Substitute the x value into first equation)
y = 36
Answer:
1) 2/3
2) y= 2x+4
Step-by-step explanation:
For number one, use the formula 
.
Insert the given coordinates into the formula.
7-1/10-1= 6/9
Simplify 6/9.
6/9÷3= 2/3
For the second one, I used desmos calculator.
Hope this helps! :)
Complementary angles add up to 90
so if A and B are complementary....and A = 40, then B = 90 - 40 = 50.
supplementary angles add up to 180
so if B and C are supplementary, and B = 50, then C = 180 - 50 = 130
