Answer:
35+7-3x4=30
Step-by-step explanation:
35+7=42 42-12= 30 so the starting number is 35.
Answer:
<u>140 in^2</u>
Step-by-step explanation:
Finding the volume
Length = 4
Width = 7
Height = 5
V = w h l = 7 x 5 x 4 = 140 in^2
Answer:
<u>The number is 170</u>
Step-by-step explanation:
Let's solve for x, this way:
x = A number that decreased by 20% of itself, the result is 136
20% = 0.2
x - 0.2x = 136 (Like terms)
0.8x = 136
x = 136/0.8 (Dividing by 0.8 at both sides)
x = 170
Let's prove that x = 170 is correct
170 - 0.2 (170) = 136
170 - 34 = 136
136 = 136
We proved that x = 170 is correct
First, find the area of the triangle. The height is 9 and the base is 33. So, multiply the base times height, which is 297. Now, divide 297 by 2. This equals 148.5. Secondly, find the area of the rectangle. Multiply the length times the width. 38•20= 760. Now, add the areas of the two shapes. 148.5+760= 908.5. So, 908.5 is your final answer. :)
Hope this helps!
