Answer:
D. Subtraction property of equality
B. 6.5
Step-by-step explanation:
First blank:
The equation is x + 6.5 = 13.
To solve the equation, you want x alone on the left side, showing "x = some number." Since 6.5 is being added to x, you need to SUBTRACT 6.5. You must do the same operation to both sides of an equation, so you need to SUBTRACT 6.5 from both sides of the equation. What allows you to subtract the same number from both sides of an equation is the
<em>D. Subtraction property of equality </em>
Second blank:
Subtract 6.5 from both sides.
x + 6.5 = 13
x + 6.5 - 6.5 = 13 - 6.5
x = 6.5
<em>Answer: B. 6.5</em>
V =πr^2h
v= 3.14×27×27×15
v=34335.9
v= 34336
Answer:
Untraceable
Step-by-step explanation:
Given:
• Upper Base of trapezoid = 8 cm
,
• Lower base = 20 cm
,
• Length of one leg (also height) = 5 cm
,
• Length of other leg = 13 cm
Let's find the area of the trapezoid.
To find the area of the trapezoid, apply the formula:

Where:
A is the area
a is the length of upper base = 8 cm
b is the length of the lower base = 20 cm
h is the height = 5 cm
Plug in the values for a, b, and h to find the area, A:

Therefore, the area of the trapezoid is 70 cm^2
