Answer:
The answer is y = 8x - 25
Answer:
Multiply the first equation by 4.
Step-by-step explanation:
4(x+y=3) which gives
4x+4y=12
and
4x-y=7
Then subtract the two equations and the x variable will be eliminated.
Answer:
10 / 28
Step-by-step explanation:
Answer:
9.5
Step-by-step explanation:
Using the pythagorean theorem a^2+b^2=c^2, we can say that 3^2+b^2=10^2.
Simplify and you get 9+b^2=100. Subtract 9 from both sides and you get b^2=91. When you take the square root you get 9.53939... round to the nearest tenth and the missing side is 9.5.
45.5% (another way to write 45 1/2 %
= .455 or 455/1000
Reducing by 5 we get 91/100
How did I get 91/100? I divided 455/1000 by 5 (numerator and denominator) And I got 91/100
