Step-by-step explanation:
Answer:
Let's solve for x.
4x+2y=5
Step 1: Add -2y to both sides.
4x+2y+−2y=5+−2y
4x=−2y+5
Step 2: Divide both sides by 4.
4x

Let's solve for x.
−4x−5y=7
Step 1: Add 5y to both sides.
−4x−5y+5y=7+5y
−4x=5y+7
Step 2: Divide both sides by -4.

Answer:
5
Step-by-step explanation:
So the square root of 21 is 4.582...
If you round 4.582.. it is 5

Answer:
350 pairs
Step-by-step explanation:
If the ratio of Athletics, Boots, and Dress shoes is 5 to 2 to 3, it means that for every 2 pairs of Boots they have 5 pairs of Athletics shoes and 3 pairs of dress shoes.
So, if they have 70 pairs of boots, we can calculate the number of Athletics as:
And if they have 70 pairs of boots, the number of dress shoes are:
Finally, they have 70 pairs of boots, 175 pairs of athletics, and 105 pairs of dress shoes. It means that they have 350 pairs in total.
70 + 175 + 105 = 350
