The ratio of boys to girls in the class is 5:7. There are 36 children in the class. How many more girls than boys are there in the class? Use the tape diagram below to solve the problem.
Answer:
Step-by-step explanation:
ratio of 5:7 means that 5/(5 + 7) = 5/12 are boys and 7/(5 + 7) = 7/12 are girls
(5/12)(36) = 15 boys
(7/12)(36) = 21 girls
21 - 15 = 6 more girls than boys.

The work of a student to solve the equation 3(2x - 4) = 8 + 2x + 6
Answer:
false
Step-by-step explanation:
3(2×−4)=8+2×+6
Multiply 3 and 2 to get 6.
6(−4)=8+2×6
Multiply 6 and −4 to get −24.
−24=8+2×6
Multiply 2 and 6 to get 12.
−24=8+12
Add 8 and 12 to get 20.
−24=20
Compare −24 and 20.

Square the binomial (2x-4)^2
Answer:
4x^2 - 8x +16
Step-by-step explanation:
(2x - 4)^2 can be looked at like this (2x - 4)(2x - 4) which can then be foiled
4x^2 -8x + 16, I presume that there is no equals zero so I don't think I can use the quadratic formula.
Thus it is 4x^2 - 8x + 16.

Robert baked 6 pies to donate to a charity dinner before he ran out of sugar. With each additional cup of sugar he buys, he can bake 1 more pie.
Write an equation that shows how the total number of pies Robert can bake, y, depends on the number of cups of sugar he buys, x.
Y=
Answer:
y=4x+6
Step-by-step explanation:
slope intercept form y=mx+b
The total number of pies Robert can bake, y, depends on the number of cups of sugar he buys, x, according to the following equation:
y = 6 + x
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
According to the following equation, the total number of pies Robert may bake, y, is determined by the number of cups of sugar he purchases, x:
y = 6 + x
This equation can be read as: "The number of pies Robert can bake, y, is equal to the number of pies he baked before he ran out of sugar, which is 6, plus the number of additional cups of sugar he buys, x."
For example, if Robert buys 2 additional cups of sugar, he can bake a total of 6 + 2 = 8 pies.
If he buys 3 additional cups of sugar, he can bake a total of 6 + 3 = 9 pies, and so on.

negative two B subtracted by C plus four B plus three C
Answer:
First we should make this word problem into an equation.
. * (_poof_) *,
-2b - c + 4b + 3c There we go. . . much better.
Now we can simplify the equation by combining like terms.
( - 2b + 4b ) + ( - c + 3c ) = ( 2b ) + ( 2c )
So the simplified form of this would be 2b + 2c.

A golfer is hitting a ball up a hill. The height of the hill is represented by the function
y = 0.125x. The height of the ball is measured by the equation
y = –16x^2+56x. How much higher will the ball be when it lands than when it was initially hit?
Answer:
3.49 ft
Step-by-step explanation:
y = 0.125x
y = –16x^2 + 56x
Set the equations equal since the height of the hill
and the height of the ball must be the same
–16x^2 + 56x = 0.125x
Subtract 0.125x from both sides
–16x^2 + 55.875x = 0
Factor out x
x(–16x + 55.875) = 0
From the zero product rule
x = 0
and
–16x + 55.875 = 0
–16x = –55.875
Divide both sides by –16
x = 3.4921875
Diiference in height
3.4921875 - 0 = 3.4921875
3.49 ft

The variables x and y are related proportionally. When x = 8, y = 14. Find y when x = 48. When x = 48, y = what.
Y might be 84. Considering 6*8=48, it would probably be the same with Y, so 14*6=84.
Hopefully this is correct but sorry if it isn't.

Teddy has 23 boxes of juice packed and plans to pack 3 additional boxes each hour. Charley has 7 boxes packed and plans to pack 5 additional boxes each hour. The equation below represents when Teddy and Charley will have packed the same number of boxes, based on x number of hours.
23 + 3x = 5x +7
After how many hours will Charley have packed the same number of boxes of juice as teddy?
Answer:
8 hours
Step-by-step explanation:
23 + 3x = 5x + 7
- 3x -3x
23 = 2x + 7
-7 - 7
16 = 2x
16/2 = 2x/2
x = 8

A garden table and a bench cost $907 combined. The garden table costs $43 less than the bench. What is the cost of the
bench?
907 - 43 = 864 / 2 = 432: 907 - 432 = 475
The garden table costs $432.
The bench costs $475.
475 + 432 = 907

2) The school theater has 17 rows of seats. Each row has 53 seats. Which statement explains how to find the closest estimation of the total number of seats in the theater? A) 17 rounds to 10, 53 rounds to 50, and 10 = 50 = 500 seats. B) 17 rounds to 10, 53 rounds to 60, and 10 x 60 = 600 seats. 9. 17 rounds to 20, 53 rounds to 50, and 20: 50 = 1.000 seats. D) 17 rounds to 20, 53, rounds to 60, and 20 x 60 = 1,200 seats.
Answer: c.) 17 rounds to 20, 53 rounds to 50, and 20: 50 = 1.000 seats
Step-by-step explanation:
*5 or more, add one more. 4 or less, give it a rest (leave it alone)*
17 rounds to 20
(the 7 is used to boost the 1 to a 2 since its more than 5, making it 20)
53 rounds to 50
(the 3 is less than 4 so we leave the 5 as is, making it 50).
Therefore, 20x50 = 1000 seats or 20:50=1000
