Answer:
55
Step-by-step explanation:
We are given the expression:
1/3z+10
We also are given z=135. Since z is equal to 135, we can substitute 135 in for z.
1/3(135)+10
Now, solve according to PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)
Multiply 135 by 1/3, or divide 135 by 3.
45+10
Add 45 and 10

Answer:A
Step-by-step explanation:
X+y+5=0
y=-x-5
If a solution exists y=y so we can say
x^2-9x+10=-x-5 add x+5 to both sides
x^2-8x+15=0 now factor
x^2-3x-5x+15=0
x(x-3)-5(x-3)
(x-5)(x-3) so x=3 and 5, using y=-x-5
y(3)=-8 and y(5)=-10
So the two solutions are:
(3,-8) and (5,-10)
