let 'x' represent the number of all the passes for the year
350 passes = 70% of all the passes
350 passes = 70% of x
0.70x = 350
by solving we find:
x = 500 passes
Answer:
-2x -10
Step-by-step explanation:
16x–18x–10
Combine like terms
-2x -10
One solution.
-20 divided by 5 is equal to -4. Unless both sides have the same number or one side has -=0 then it’s one solution
The given equations are:
5x - 2y = 88
3x + 4y = 58
Multiplying the 1st equation by 2, we get the new set of equations as:
10x - 4y = 176
3x + 4y = 58
Adding the two equations, we get:
10x - 4y + 3x + 4y = 176 + 58
13x =234
x = 18
Using the value of x in 1st equation, we get:
5(18) - 2y = 88
- 2y = 88 -5(18)
-2y = -2
y = 1
So, the solution of the equation is (18, 1)
Numbers 2, 4 and 5 are the correct answers.
Hope this helps!
