Answer:
x=8 and y=53
Step-by-step explanation:
Given function:
- y=5x+13
- y=x+45
Find x:
- the two equation, the x and are breaked apart..
- so find a number that they can both equal to together and has the same y.
- multiply by 8..
·
- combine the terms for x and 13
- since x is 8 then if we add 8 with 45 it should be 53...
y is:
- this means that y=53.
Therefore, x=8 and y=53..
Answer:
Step-by-step explanation:
Circumference = C = 31.4 ft
We know that,
<h3>C = 2πr</h3>Where, r is the radius
31.4 = 2(3.14)r
31.4 = 6.28(r)
Divide 6.28 to both sides
31.4/6.28 = r
5 ft. = r
<h3>r = 5 ft.</h3>Now,
<h3><u>Finding area:</u></h3>A = πr²
A = (3.14)(5)²
A = (3.14)(25)
<h3>A = 78.5 ft²</h3>
