Find the GCF of 32a, 48b, and 16ab
andriy [413]
16 is the answer. All 3 numbers can be divided by 16 at most. It can’t be 16a because 48b does not have a. It can’t be 16b because 32a does not have b.

4x + 2y = -12 3x + y = -10 please help system by substitution.
padilas [110]

Answer:

(-4, 2)

Step-by-step explanation:

4x+2y=-12

3x+y=-10

Start by dividing the first equation by 2 to simplify it...

2x+y=-6

Then, subtract -2x from both sides to isolate y...

y=-2x-6

Substitute -2x-6 for y in the second equation...

3x-2x-6=-10

Combine like terms...

x-6=-10

Add 6 to both sides

x-6+6=-10+6

x=-4

Plug -4 in for x to solve for y:

3(-4)+y=-10

-12+y=-10

Add 12 to both sides

-12+12+y=-10+12

y=2

(x,y)=(-4,2)

A rectangular field is four times as long as it is wide. If the perimeter of the field is 520 yards, what are the field's dimens
juin [17]

Answer:

Width = 52 yards

Length = 208 yards

Step-by-step explanation:

(2 * 4x) + 2x = 10x

10x = 520

x = 52

52 * 4 = 208

(208 * 2) + (52 * 2) = 416 + 104 = 520 yards

Your welcome!
