Area of a trapezoid = ((a+b)/2) * h
a = x + x
b = z + z
h = y
A = ((4 + 12)/2) * 6
A = ((16)/2) *6
A = 8 * 6
A = 48
answer is B

Given:
Jing is helping the kindergarten teacher put together bags of crayons.
Each bag has 4 crayons, and 1/4 of the crayons in each bag are green.
What fraction of the crayons in 3 bags are green?
<u>Solution:</u>
1 bag contains number of crayons = 4
1 bag contains number of green crayons = 
Total number of bags = 3
Total number of crayons in 3 bags = 4
3 = 12
1 bag contains number of green crayons = 1
Total number of green crayons in 3 bags = 1
3 = 3
Fraction of the green crayons out of total = 3 out of 12 = 
Therefore, fraction of the crayons in 3 bags are green are 
Answer:
x+2x+6=87
Step-by-step explanation:
let x represent the first number. 2x+6 would represent the second number since it's 6 more than (which would be addition) twice the first number (so you'd multiply the first number (which is represented by x) by 2. then, you'd set up the equation to be equal to 87.
so, the equation would be:
x+2x+6=87
Answer:
5n-10 < 6n-8
n - is the variable that's stands for the unspecified number
step 1. ten is less than 5 times a number
step 2. LESS THAN SIGN :)
step 3. six times the number decreased by 8
......................
oh and if you're looking to simplify that problem I believe it would be worked out like this....5n-10<6n-8....subtract 5 from both sides....-10
