Answer:
40/27
Step-by-step explanation:
-1/4(4/9-3x)-2/9=7/9
-1/9+3/4x=7/9+2/9
3/4x=9/9-(-1/9)
3/4x=9/9+1/9
3/4x=10/9
x=(10/9)/(3/4)
x=(10/9)(4/3)
x=40/27
Answer:
134
Step-by-step explanation:
670/5 = 134
d = b - 3 / 10
Step-by-step explanation:
b = 10d + 3
- Place +3 in the other side of the equal sign
- + 3 becomes - 3
- b - 3 = 10
- Divide both sides by 10 to make d the subject
- b - 3 / 10 = 10d / 10
- d = b - 3 / 10
Answer:
The man sold 190 tie-dyed T-shirts
Step-by-step explanation:
This problem can be modeled by a system of equations.
I am going to call x the number of tie-dyed T-shirts that the man sold and y the number of silk-screened shirts that he sold.
We have that he sold 5 times as many tie-dyed T-shirts as silk-screened shirts. So this gives us our equation 1)
1) x = 5y.
We also know that altogether, he sold 228 shirts. So this gives us our equation 2)
2) x + y = 228.
Now, we solve the system formed by equations 1) and 2)
x = 5y
x + 5y = 228
6y = 228
y = 38
x = 5*38
x = 190
So, in all, the man sold 190 tie-dyed T-shirts and 38 silk-screened T-shirts.
