Answer:
Let p be the number of phones sold and a be the number of accessory sold.
9p + 4a = 253
a - p = 8
Step-by-step explanation:
He gets $9 for every phone and $4 for every accessory, so you can write this as
9p + 4a
Then he made a total of $253 do the new equation is
9p + 4a = 253
We are also given that he sold 8 more accessories than phones. So we can write this as
a = p + 8
rearrange that so that all the variables are to one side.
a - p = 8
Now you have the two equations needed to solve the for the variable. The question didn't ask me to solve for the variable so I'll leave it here.

Answer:
1 1/14 lbs
Step-by-step explanation:
We can use ratios to solve
2/3 crate 1 crate
----------------- = -----------------
5/7 lb x lbs
Using cross products
2/3x = 5/7 *1
Multiply each side by 3/2
3/2 * 2/3 x = 3/2 * 5/7
x = 15/14
x = 1 1/14
1)
neverminding how many grams or liters...or whatever unit for now
we know one bag of grass covered 1/6 of the lawn, "a whole" or 1, is 6/6
if 1 bag covers 1/6, to cover 6/6 is just 1/6 +1/6 +1/6 +1/6 +1/6 +1/6 , or 6 bags
2)
one can was enough for 1/4 of the sprayer, a full sprayer is 1 whole or 4/4, so 1/4 + 1/4 + 1/4 + 1/4 or 4 cans
3)
one potato gives enough for 1/3 for a lighbulb, again, 1 whole is 3/3, so 1/3 +1/3 +1/3 , so 3 potatoes
