Answer:

71%

Step-by-step explanation:

She has 65% for 1st paper which have 120marks, we can calcule how marks she done:

120*0,65=78

On the 2nd pper she done:

80*0,80=64

The total marks was 120+80=200

She done 78+64=142

200—>100%

142—->x%

X=14200/200=71

Youth tickets(y) cost $2 for a ride, while adult tickets(x) cost $3. The amount of money earned is $54. If all the seats were fi
Paha777 [63]
There are no constants here. But we have x and y here.
We will create an equation which is:
2y+3x=54.
But we will also create a second equation which states the number of seats.
x+y=24.

Now we do the two-equation solving method.
2y+3x=54
-2(x+y=24)

2y+3x=54
-2x-2y=-48

x=6

To solve for y, plug in x into one of the original equations. Which one doesn't matter.

y+6=24
y=18

What is the solution to the equation 2(4-3x)+5(2x-3)= 20-5X2​
Alja [10]

Answer:

7-16x=10. I'm sorry I'm not good at math but it never hurts try, right?

Step-by-step explanation:

Multiply the parentheses first which would give you

8-6x+10x-15.

Next add 6x+10x which would give you

8-16x-15.

Then subtract 8-15 which would give you

7-16x=20-5x2. Then work the problem from there.

7-16x=20-10.

7-16x=10.
