Answer:
d) 10
Step-by-step explanation:
x ÷ 
+ 8 = 13
substitute 10 for x:
⇒ 10 ÷ + 8 = 13
solve:
1) divide 10 by

Answer:
Cost of ordering t-shirts the same at both sides is 7
The cost is $85
Step-by-step explanation:
let x equal the number of tshirts
Hence:
15 + 10x = 50 + 5x
10x-5x= 50-15
5x = 35
35/5x
x = 7
Therefore the cost of ordering t-shirts the same at both sides is 7
The cost is $85
Answer:
y=3x+5
Step-by-step explanation:
- start by putting 18x on the other side of the equation
- to do this you have to subtract, so it will be -18x now
2. now you have -6y=-18x-30
3. now you need to divide -6 by -18 and -30 on the other side to get y by itself
4. this will leave you with y=3x+5 because 6 divided by 18 is three and 30 divided by 6 is five.
I hope this helps!!
