Answer:
-40 °F = -40 °C
Step-by-step explanation:
(1) F = 1.8 C + 32
If the Fahrenheit and Celsius temperatures are the same, then
(2) F = C Substitute (2) into (1)
C = 1.8C + 32 Subtract 1.8 C from each side
C – 1.8 C = 32 Combine like terms
-0.8C = 32 Divide each side by -0.8
C = -32/0.8
(3) C = -40 Substitute (3) into (1)
F = 1.8(-40) + 32
F = -72 + 32
F = -40
So, -40 °F = -40 °C
The thermometer below shows that -40 °F = -40 °C.
Answer: y= (-1/5)x -4
First move the x over t the other side of the equation. Now we have 5y=-x-20. Next divide everything by 5 to get y= (-1/5)x -4
23,457 - 19,436 = 4,021
23,457 + 4,021 = 27,478
total income next year - 27,478
Answer:
the longest side is 25
Step-by-step explanation:
the equation would be x+ x+1 + 7 for the 3 sides of the triangle
x + (x+1) + 7=56
combine like terms
2x+8 = 56
subtract 8 from each side
2x = 48
divide by 2
x = 24
the sides are
x=24
x+1 = 25
7
the longest side is 25
