Answer:
x = 24.5
Step-by-step explanation:
the angles form a straight line, and a straight line equals to 180°
=> (5x + 8) + (3x - 24) = 180
=> 8x = 196
=> x = 24.5
Answer:
64x
Step-by-step explanation:
because 4 * 2 is in parenthesis, that means you multiply 8x by them.
8x (4*2)
8x (8)
64x
Answer:
x = -1
Step-by-step explanation:
Well start off by simplifying each rate:
17/15 --> can't be further simplified
68/60 = 34/30 = 17/15
So then, yes these rates are equivalent.
Also, you can divide 17/15 and 68/60 and compare the quotients.
Isolate the B. Note the equal sign. What you do to one side, you do to the other. Subtract C and A from both sides
B + A (-A) + C (-C) = D (-A) (-C)
B = D - A - C
B = D - A - C is your answer
hope this helps
