Answer:
1) 9
2) 7
3) -10
4) -54
5) -64
Step-by-step explanation:
It’s just basic substitution
Hope this helps!
35. is c : square root of 64 is 8 and the square root of 8 can be simplifed to 4 x 2, square root of 4 is 2
36 is d : Denominator of the fraction represents what it is being rooted by and the numerator is what the regular number is squared by.
System: x + y = 44; x = 2y + 2
Solve with substitution: x = 30; y = 14
x + y = 44
x = 2y + 2
Substitute 2y + 2 for x
2y + 2 + y = 44
3y + 2 = 44
Subtract 2 on both sides.
3y = 42
y = 14
Now substitute back in.
x + 14 = 44
Subtract 14 on both sides.
x = 30
