Answer:
a = 43 / 30
Step-by-step explanation:
-7 ( 8a -9 ) = -23 + 4a
-56a + 63 = -23 +4a
-60a + 63 = -23
-60a = -86
a = 43 / 30
90 degrees
180 degrees
360 degrees
0 degrees
Answer:
Step-by-step explanation:
This might be easier to do in decimals. Let's try it.
3/5 = 0.6
1/10 = 0.1
rate = holes / hours
rate = 0.6/0.1
rate = 6 holes per hour
Try it with fractions.
rate =
Invert and multiply the 1/10
rate =
= 30/5 = 6
It's the same answer. Pick the method that you feel most comfortable with.
Answer:
(5, - 7 )
Step-by-step explanation:
A translation rule of
(x, y ) → (x + 1, y - 3 )
means add 1 to the original x- coordinate and subtract 3 from the original y- coordinate, that is
(4, - 4 ) → (4 + 1, - 4 - 3 ) → (5, - 7 )
