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
Answer:
270 ÷ 30 = 9
Step-by-step explanation:
9x3=27
90x3 = 270
27 ÷ 3 = 9
270 ÷ 30 = 9
90 x 3 = 270
30 x 9 = 270
Answer:
ok so i am just dividing it out the answer would be 0.42185792
Step-by-step explanation:
3.86/9.15=0.42185792
Answer:
381/90
Step-by-step explanation:
x = 4.2333.... ----------(I)
Number of digit after decimal is 2 ( 4 , 3). So multiply both sides by of equation 100
100x = 423.333..... (II)
One digit (3) is repeating.So, multiply by both sides of equation (I) by 10
10x = 42.333....... -----(III)
Subtract Equation (III) from (II)
(II) 100x = 423.333......
(III) <u>10x = 42.333......</u> {Subtract}
90x = 381
x = 381/90
