2 x -2 x 2 = -8
+ 3 x -3 x 3 = -9
- (-2) x 2 = -4
+ 4 x 5 x 2 = 40
- (-2) x 2 = -4
So then -8 + (-9) - (-4) + 40 - (-4) = 31
Glad I can help :)
Answer:
-5
Step-by-step explanation:
To solve for z, divide both sides of this equation by -0.25:
1.25
z = ----------- = -5
-0.25
Answer:
y = 2^{x}
Step-by-step explanation:
Given the above data for x and y.
From the algebraic expression;
y = 2^{x}
We can deduce that the value of y is equal to two (2) raise to the power of x.
When x = 1, y = 2
y = 2^{x}
y = 2^{1}
y = 2
When x = 2, y = 4
y = 2^{x}
y = 2^{2}
y = 4
When x = 3, y = 8
y = 2^{x}
y = 2^{3}
y = 8
The above calculations can be used to determine the other values of y with respect to x.
Answer:
N = R - 7

5
Step-by-step explanation:
R=5n+7
subtract 7 from both sides
5n = R-7
divide both sides by 5
n = R-7

All the corners of a rectangle is equal to 90 degrees. So you need to set (x-1) and (2x+10) equal to 90 and then solve for x.
(x - 1) + (2x + 10) = 90
<em>Combine the like terms...
</em>3x + 9 = 90
<em>Subtract both sides by 9...
</em>3x + 9 - 9 = 90 - 9
3x = 81
<em>Divide both sides by 3...
</em><em>3x = 81
</em>(3x) / 3 = 81 / 3
x = 27
