Step-by-step explanation:
1.8C + 32 would be ur expression
when C = 25
F = 1.8C + 32
F = 1.8(25) + 32
F = 45 + 32
F = 77 degrees <====
The answer for #2 is A
And the answer for #3 is B
Answer:
see below
Step-by-step explanation:
slope = (y₂ - y₁) / (x₂ - x₁) <=== formula
= (2 - (-7)) / (18 - 18)
= 9 / 0
= 0 <=== slope
Create a system of equations
x + y = 123
5x + y = 343
I use substitution
y = 123 - x
5x + 123 - x = 343
4x + 123 = 343
4x = 220
x = 55
Plug in
x + y = 123
55 + y = 123
y = 68
Check
5x + y = 343
5(55) + 68 = 343
275 + 68 = 343
343 = 343
The square root of 169 is 13 and 170 is 13.03
