Answer:
The solution to the system of equations is 
.
Step-by-step explanation:
We are given a system of equations:
- We need to solve these by substitution, so we need to solve one equation for a variable and then substitute the value of that variable into the other equation.
- After doing this and solving for the opposite variable, we need to insert this into the original equation and solve for the initial variable.
- Therefore, to solve one of the equations, we will solve it to put it in slope-intercept form and solve for y. The easier equation to work with is equation two.
Now, we've solved for y. So, we can substitute this into either equation and solve for x.
Now, we substitute our value for x into one of the original equations and solve for y.
Therefore, the solution to our system of equations is:
Answer:
10c=h
Step-by-step explanation:
The graph showed 2h=20c
so h=10c
Answer:
2 cans
Step-by-step explanation:
Given that :
Radius of pool = 30 feets
Using the relation for the Area of a circle :
Area = pi*r^2
Thus,
Area of pool = 3.14 * 30^2
Area of pool = 3.14 * 900 = 2826feet²
Paints are sold in cans of 5 gallon
5 gallon of paint = 1500 feet²
Least number of 5 gallon can required :
2826 feet² / 1500 feet² = 1.884 cans
Hence,
Least number of 5 gallon can required = 2 cans
Answer:
l = 11.19 feet
Step-by-step explanation:
Given that,
The width of a roll of gasket material, b= 16 inches
We need to find the length needed to obtain 15 sq ft of the material.
We know that,
1 foot = 12 inches
⇒ 16 inhces = 1.34 feet
For a rectangular shaped object, area is given by :
A = l×b
So, the required length is 11.19 feet.
Answer:
distance around the triangle refers to the perimeter of that equilateral triangle so 35 + 35 + 35 = 105cm
