63 x 38 = 2394
63 x 10 = 630
600 x 3 = 1800
30 x 3 = 90
1800 + 90 = 1890
63 x 2 = 126
630 - 126 = 504
1890 + 504 = 2394
We see two parallel lines crossed by a transversal.
The two labelled angles are alternate interior angles, hence they are equal.
The equality allows us to equate the two expressions and hence solve for x.
8x-3=5x+42
transpose terms
8x-5x=42+3
solve for x
3x=45
so x=45/3=15.
This means 5x+42=5*15+42=75+42=117 degrees.
Reduce the numbers with 3. Any expression divided by 1 remains the same.
Step-by-step explanation:
i think you missed a decimal place for 8.5°
when temperatures drop it means minus
so
-7.5-5-8.5= -21°
Answer:
The first first in solving for x is do the distributive property to the left and right of the eqaution. Distribute 2 with 6x and 6. Distribute 3 with x and -4.
Step-by-step explanation:
PEMDAS states that you do things in the parenthesis first.
