Answer:
-1/2
Step-by-step explanation:
We need to get a common denominator of 10
-4/5 *2/2 = -8/10
-8/10 +3/10
-5/10
Divide the top and bottom by 5
-1/2
The answer should be 9 if I’m not mistaken
Answer:
see below
Step-by-step explanation:
4(5 - 3x)
The first step is to multiply the 4 by each of the terms inside the parentheses
4*5 - 4*3x
20 -12x
Now subtract the products
20-12x
Step-by-step explanation:
x/5 + 7 = 16
x/5 = 16 - 7
x/5 = 9
x = 9×5
= 45
The best way to do this is to make up values for the sides.
Say the lengths of square B's sides are each 4 cm. That means A's sides are 2 cm.
So, the area of square B is 4^2 = 16 cm^2, and A's area is 4 cm^2. We can see the shaded area is half of A, so it's 2 cm^2.
What percent of 16 is 2?
2 / 16 * 100 = 12.5%
