Equilateral triangle have the same side lengths. Perimeter = sum of all sides
(4x - 3) + (4x - 3) + (4x - 3) = 63
Remove parentheses
4x - 3 + 4x - 3 + 4x - 3 = 63
Combine like terms
12x - 9 = 63
12x = 72, x = 6
Solution: x = 6
Answer:
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=300 (1)
5x+8y=300*7
5x+8y=2100(2)
First, you can isolate x in (1):
x=300-y (3)
Now, you can replace (3) in (2):
5(300-y)+8y=2100
1500-5y+8y=2100
3y=2100-1500
y=600/3
y=200
Then, you can replace the value of y in (3) to find x:
x=300-200
x=100
According to this, the answer is that he should use 100 pounds of dried pineapple and 200 pounds of dried apricots.

The parallelogram shown below has an area of 72 units squared. The base is 6 and the other side is 13 Find the missing height.
Here is my answer:
Given:
The area: 72 units squared.
The base: 6 units
As we know that the area of the parallelogram is represented by below formula:
A = b*h where h is the height and b is the base
In this situation, we know:
72 = 6*h
<=> h = 12
So the missing height is 12 units
