Answer:
The equation that can be solved to find the number of nails in each box =
5x = 460
The number of nails in each box = 92 nails
Step-by-step explanation:
A carpenter bought 5 identical boxes of nails. She used 25 nails for a project and now has 435 nails left. Which equation can be solved to find the number of nails in each box.
Let the number of nails in each box be represented by x
Therefore our Equation =
5x = 25 + 435
5x = 460
Solving for x
5x/5 = 460/5
x = 92 nails
Therefore, the number of nails in each box = 92 nails
We know that she spent $39, and has 3/4 of the original amount left. Our goal is to find the original amount. We can use the equation. x - 39 = 3/4x. Once we subtract x on the left hand side, we get -39 = -1/4x. Once we multiply -39 by -4, we get 146. She originally had $156.
Answer:
16
Step-by-step explanation:
Shape C is A trapezoid
Area of trapezoid = 
where a and b = base lengths and h = height
The trapezoid has the following dimensions
base 1 = 3 units
base 2 = 5 units
height = 4 units
Using these dimensions we plug in the values into the formula stated above.
Hence the area of shape C = 16 square units
Answer:
h = 2.7 m
Step-by-step explanation:
ΔADE and ΔABC are similar, hence ratios of corresponding sides are equal
DE / BC = AD / AB, that is
h / 0.9 = 18 / 6 ( cross- multiply )
6h = 16.2 ( divide both sides by 6 )
h = 2.7
