Given that 8 x − 3 y = 36 Find x when y = 3 Give your answer as an improper fraction in its simplest form.
Answer:
5.62
Step-by-step explanation:
8x-3y=36
8x-3×3=36
8x=36+9
x=5.62
Answer:
x= 45/8
Step-by-step explanation:
8x - 3y = 36
8x - 3(3) = 36
8x - 9 = 36
8x=45
x=45/8

Brianna used two congruent parallelograms and a square to create the figure.
What is the area of the figure Brianna created in square feet?
Answer Choices:
A: 27 ft²
B: 24 ¾ ft²
C: 67 ½ ft²
D: 33 ¾ ft²
Answer:
D. 33 3/4 ft²Step-by-step explanation:
The figure comprises of a square with side of 4 1/2 ft and two parallelograms with base of 4 1/2 ft and height of 1 1/2 ft
Total area is:
(4 1/2)² + 2(4 1/2)( 1 1/2) = (4 1/2)( 4 1/2 + 2(1 1/2)) = 9/2(9/2 + 3) = 9/2(15/2) = 135/4 = 33 3/4 ft²Correct option is D

2) -8(-8x - 6) = -6x – 22
Answer:
x = -1
Step-by-step explanation:
-8(-8x - 6) = -6x - 22 {Use distributive property}
(-8) * (-8x) - 6 *(-8) = -6x - 22
64x + 48 = -6x -22 {Add 6x to both sides}
64x + 6x + 48 = -22 {Subtract 48 from both sides}
70x = -22 -48
70x = -70 {Divide both sides by 70}
x = -70/70
x = -1
ANYONE HELP PLEASE<3
Answer:
y = (2/3)x + 7
Step-by-step explanation:
Slope intercept form is y = mx +b
1) We start off with y =
2) m = slope. Since we know that the slope is 2/3 we can plug it in. y = 2/3x
3) b is y-intercept which = 7.
Put it all together: y = 2/3 x + 7
whats the difference between slope and rate of change?
Answer:
Slope is the ratio of the vertical and horizontal changes between two points on a surface or a line
Step-by-step explanation:
If coordinates of any two points of a line are given, then the rate of change is the ratio of the change in the y-coordinates to the change in the x-coordinates.
The line with equation y = 2 x + 3 is reflected in the x -axis. Which of the following is the equation of the new line

The sides of a triangle measure 2x + 5, X – 4, and
3(2x + 1). What is the perimeter of the triangle?
Answer:
9x+4
Step-by-step explanation:
perimeter= sum of all sides
perimeter= (2x+5)+ (x-4)+ 3(2x+1)
= 2x+5+x-4+ 6x+3
= 2x+x+6x+5+3-4
= 9x+8-4
=9x+4
