Answer:
Step-by-step explanation:
15 bags for $20 can be represented with 15/20
so x bags for $4 can be represented with x/4
now if you proportion it out (ricochet), 4x15 is 60, 60 divided by 20 is 3, so you can buy 3 bags of potatoes with $4.
OR
you could do 15/20 is 0.75
0.75 times 4 is 3, so $4 can buy you 3 bags.
<span>6a+14=-7-a
you simplify the equation to the form, which is simple to understand
<span>6a+14=-7-a
you move all terms containing a to the left and all other terms to the right.
<span>+6a+1a=-7-14
you need to simplify left and right side of the equation.
<span>+7a=-21
you divide both sides of the equation by 7 to get a.
<span>a=-3</span></span></span></span></span>
Answer:
X = 0
Y = -3
Step-by-step explanation:
In this situation you would choose elimination.
-6x+y=-3
7x-y=3
---------------
x = 0
plug back in to find y
(-6)(0) + y = -3
0 + y = -3
y = -3
plug in to other equation for double check
7(0) - (-3) = 3
0 + 3 = 3
3 = 3
Hope this helps
