Answer:
1.
d. (-14) + (-8)
2.
a. (-14) + 8
Step-by-step explanation:
(-14) - 8 is equal to (-14) + (-8) because we still add two negative values so the result wouldn't change.
(-14) - (-8) is equal to (-14) + 8 because there's two negative sign in front of 8 and two negative values multiplied makes a positive result.
Hey there!
ORIGINAL EQUATION:
0.75(2 + 6 x 4 - 2 × 7 - 2)
WORKING WITHIN the PARENTHESES:
2 + 6 x 4 - 2 × 7 - 2
= 2 + 24 - 2 × 7 - 2
= 26 - 2 × 7 - 2
= 26 - 14 - 2
= 12 - 2
= 10
NEW EQUATION:
0.75(10)
SIMPLIFY IT!
7.50 ≈ 7.5
Therefore, your answer should be: 7.5

Answer:
17148.59 in^3
Step-by-step explanation:
This volume is calculated as follows: V = (4/3)(3.14)(16 in)^3 = 17148.95 in^3
3x + 6 = 48 (alternate angles are equal)
- 6
3x. = 42
÷3
x = 14 degrees
180-48 - 2y + 5y-9 =180
123 + 3y = 180
-123
3y = 57
÷3
y = 19 degrees
Explanation:
To find the last angle on the top straight line, do:
180 - (the 2 given angles).
So, 180 - (3x + 16, which is 48 due to alternate angles being equal). Then, minus the 2y.
(180 - 48 - 2y) & simplify => 132 - 2y
This gives you the equation for the missing angle on our top straight line.
Thus, co-interior angles add to 180. So, we add the new equation (132 - 2y) to 5y - 9.
Simplify
=> 123 + 3y (because - 2+5 =3)
and put it equal to 180. Solve for y
Hope this helps!
