Ugh I hate these... Inverse property of multiplication.
Answer:
46
Step-by-step explanation:
5x = 3x - 2 + 34
5x = 3x + 32
2x = 32
x = 16
plug back in
3( 16 ) - 2
48 - 2
46

Step-by-step explanation:
You need to divide 70 by 2.5 equals 28. Than you need to times that by 9.5.
Answer:
(-2,-3) and (3,2)
Step-by-step explanation:
sub in x-1 into y
x^2 + (x-1)^2 = 13
x^2 + (x-1)(x-1)=13
x^2 + x^2 -2x +1 = 13
2x^2 -2x-12=0
solve for x by factoring (quadratic formula, product sum etc..)
x= -2 and 3
plug in those values into y=x-1 and solve for y
2/3 is the same 4/6
7/2 is the same as 21/6
4/6 + 21/6 = 25/6
So the answer is 25/6, not 25/5.
