64 and 28 have a GCF of 4, since 64 = 4 x 16, 28 = 4 x 7, and 7 and 16 have no factors other than 1 in common. Knowing that, we can rewrite 64 + 28 as
4 x 16 + 4 x 7
and then use the distributive property to rewrite it again as
4 x (16 + 7)
Answer:

Step-by-step explanation:
To solve this, we have to plug in 1/3 for x:

Hi there!
Let's first determine the x-intercept. When dealing with an x-intercept we must realise the y-coordinates equal 0.

Add 21 to both sides.

Divide both sides by -2.

Therefore, the x-intercept is the point (10 1/2; 0).
--------------------------------------
Now let's continue with the y-intercept, which is easier. When dealing with an y-intercept we must realise the x-coordinates equal 0.

Therefore, the y-intercept is the point (0; -21).

X=14
Answer:
Okay!
Step-by-step explanation:
Let's solve for x
5x+2y=3
Step 1: Add -2y to both sides.
Step 2: Divide both sides by 5.
