Answer:
Total children = 52
Step-by-step explanation:
The question says that "The ratio of boys to girls in the school play is 5 to 8. There are 32 girls participating in the play. How many children participate in the school play?
"
Let there are 5x boys and 8x girls in a school play.
Total no of girls participating in the play = 32
ATQ,
8x = 32
x = 4
Boys = 5x
= 5(4)
= 20
Total children = boys + girls
= 20 + 32
= 52
Hence, there are 52 children participating in the school play.
3 outfits because there is three pants that can be grouped with 3 shirts and 3 ties.
Substitution method is used to solve the linear system of equations for one or more variables.
Consider the first equation y = 3x + 3 -----(1)
In equation (1) plug in y=x-1, we get
x -1 = 3x + 3
Add -3x on both side , we get
x-3x -1 = 3x-3x +3
-2x-1=0 + 3
Now add +1 on both sides, we get
-2x-1+1= 3+1
-2x + 0 =4
Now divide both side by -2
-2x/-2= 4/-2
X= -2
Now put x=-2 in the the second equation,
y=x-1
y=(-2)-1
y=-3
Solution(-2,-3)
36.75 - X= X
( not completely sure if this is correct pretty sure tho)
Answer:
23 over 15 or 1.533
Step-by-step explanation:
Group like terms:
1+(3/5+-1/15)
Find LCD:
1+9/15+-1/15
Combine numerators:
15/15+8/15
And you get 23/15
Simplified:1 8/15
Decimal: 1.533
