Answer:
x = 3.6
B. {7.88}
Step-by-step explanation:

x · 10 = 6 · 6
10x = 36
10x ÷ 10 = 36 ÷ 10
x = 3.6

8 · x = 9 · 7
8x = 63
8x ÷ 8 = 63 ÷ 8
or x = 7.875
7.875 rounded to the nearest tenth is 7.88.
Surface area of the square pyramid = 217.8 in²
Solution:
Side length of the square = 9 in
Area of the square = side × side
= 9 in × 9 in
= 81 in²
Area of the square = 81 in²
Perimeter of the base = 4 × 9 in = 36 in
Slant height of the triangle = 7.6 in
Surface area of the square pyramid



= 217.8 in²
Surface area of the square pyramid = 217.8 in²
Answer:
-78
Step-by-step explanation:
-78 - 20 = -98 which is less than -37,
im sorry this answer might be wrong i tried my best
Answer:
D) 5
Step-by-step explanation:
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Divide 2 from all terms within the equation:
(2y)/2 = (10x - 8)/2
y = (10x)/2 - (8)/2
y = 5x - 4
Note the slope-intercept form:
y = mx + b
y = y
x = x
m = slope
b = y-intercept.
In this case, 5 is in place of m, or your slope.
D) 5 is your answer.
