The GCF of 72 is 60 is 12.
Answer:
Letter c
Step-by-step explanation:
You are distributing the 7 to each term in the parentheses.
7(8x) is 56 x
Here is the tricky part. You can think of it a couple of ways:
7(-4y) = -28y a positive times a negative is a negative.
or 7(4y) = 28 , but then remember that you are subtracting so it will become -28
7(6) = 56
56x - 28y +42
Answer:
a = 9
Step-by-step explanation:
-6a + 2a = -36
-4a = -36
a = -36/-4
a = 9
In order to graph y=-x+5, make a table and plug in values of x to find y. to find your points, use x,y.
x: 1 y: 4
x: 2 y: 3
x:3 y: 2
x: 2 y:1
these are the first four points for the first equation. to plug in, use ramdom numbers for x, such as 1, 2, and 3. y= -(1) +5
Answer:
x = 
Step-by-step explanation:
Given
+
=
( express the sum on the left as a single fraction )
=
( cross- multiply )
x(b + a) = ab ← divide both sides by (b + a)
x =
