Answer:
97+18+20=97+38=135
Step-by-step explanation:
97+(3×6)+(5×4)=
97+18+20=
97+38=135
I think the answer is 7×(3×5)=(7×3)×5
Supplementary angles are angles that add up to 180 degrees.
Angle 1 = x
Angle 2 = x + 10
Since they are supplementary, we can set then equal to 180
x + x + 10 = 180
Combine like terms
2x + 10 = 180
Subtract 10 from both sides
2x = 170
Divide both sides by 2
x = 85
Angle 1 = 85 degrees
Angle 2 = 85 + 10 = 95 degrees
Answer for the first box = -31.67
Answer for the second box = 17.22
===============================================
Work Shown:
Plug in F = -25 and solve for C
F = (9/5)C+32
-25 = (9/5)C + 32
(9/5)C + 32 = -25
(9/5)C = -25-32 ... subtract 32 from both sides
(9/5)C = -57
C = (5/9)*(-57) ... multiply both sides by 5/9, its the reciprocal of 9/5
C = -31.667 approximately
C = -31.67 rounding to 2 decimal places
This shows that -25 degrees F converts to roughly -31.67 degrees C.
-----------------
Repeat the same basic steps, but now use F = 63
F = (9/5)C+32
63 = (9/5)C+32
(9/5)C+32 = 63
(9/5)C = 63-32
(9/5)C = 31
C = (5/9)(31)
C = 17.222 approximate
C = 17.22
----------------
If the temperature ranges from -25 degrees F to 63 degrees F, then this converts to the range of roughly -31.67 degrees C to 17.22 degrees C
Answer:
e=2
Step-by-step explanation:
14e-7-3=6+6e
14e-10=6+6e
14e-6e=6+10
8e=16
e=2
