Answer:
x=32/7
Step-by-step explanation:
7x-2(1)=30 Plug in 1 as y and simplify.
7x-2=30 Add 2 on both sides of the equation.
<u>+2 +2</u>
7x=32 Divide both sides of the equation by 7.
<u>/7 /7</u>
x=32/7
Hope this helps...have an amazing day (｡･∀･)ﾉﾞ

Answer:
(0,0)
Step-by-step explanation:
Let's put this in standard form in our minds.
Standard form of a circle is (x-h)^2 + (y-k)^2 = r^2.
(h,k) is the center, and r is the radius.
x^2 + y^2 = 121
(x-0)^2 + (y-0)^2 = 121
We can just think about this like they have a secret 0 as the h and k! The center is just (0,0). Good luck in your math class:)
Answer: $3.69
Step-by-step explanation:
Laura bought 4 1/3 bushels of apples.
Firs convert this to an improper fraction for easier calculation:
= 13/3 bushels of apples.
If cost $16 altogether, individually they must cost:
= Cost / Quantity purchased
= 16 ÷ 13/3
= 16 * 3/13
= $3.69
<em>Note: You can divide by a fraction by multiplying the inverse of that fraction. </em>
