Answer:
a
ethe answer is a becayse if you subtract 12 from 20 you would get 8 and thats answer.th
Step-by-step explanation:
If you're saying that a×b=c, and a and b are the same number, then you need to find the square root of 60, or a number that will equal 60 when multiplied together since c=60. 60 is not a perfect square, but 7 squared is 49 and 8 squared is 64. So, the answer is going to be 7.something. If you √60 into a calculator, you get 7.74597. The five rounds up the four in the hundredths place, so the square root of 60 is about 7.75

cost = 7
c = s*7
independent is s
dependent is c
Answer:
Pencil: $0.60 Rubber: $0.48
Step-by-step explanation:
Let the cost of a pencil be p and the cost of a rubber be r.
(Equation 1)
(Equation 2)
Divide both sides by 4:
Substitute this into Equation 1:
Multiply both sides by 4:
Divide both sides by 9:
Since r + p = 1.08,
Answer:
Step-by-step explanation:
eq. of a circle is (x-h)²+(y-k)²=r²
where center=(h,k)
and radius=r
so (x+2)²+(y+5)²=4²
