= 6x^2 + (15-8)x + 24
= 6x^2 + 15x - 8x + 24
= 3x( 2x+5 ) - 4( 2x+5 )

Charlie bought hamburgers today and drinks for his friends. Each burger cost $3.75 and each drink cost .50 cents. In total Charlie paid $25.50 for his order. Write an equation that represents the number of burgers he bought,h, and the number of drinks he bought ,d.
Answer:
3.75h + 0.5d = 25.50
Step-by-step explanation:
Let 'h' represent the number of hamburger.
Let 'd' represent the number drink.
From the question given:
We were told that a hamburger (h) cost $ 3.75.
Therefore, h number hamburger will cost = h × 3.75 = 3.75h
Also, we were told that a drink cost 0.50 cent.
Therefore, d number of drink will cost = d × 0.5 = 0.5d
In total Charlie paid $25.50 for his order i.e
Total cost of hamburger + total cost of drink = 25.50
Total cost of hamburger = 3.75h
Total cost of drink = 0.5d
3.75h + 0.5d = 25.50
Thus, the equation representing the number of hamburgers (h) and the number of drinks (d) that Charlie bought is given as:
3.75h + 0.5d = 25.50

Moretti's Ristorante & Pizzeria has two different soda sizes, Regular and Large. The Regular size soda is 22 ounces and the Large soda is 64 ounces. By what percent does the amount of soda increase between the different soda sizes? Round to the nearest percent
Answer:
280
Step-by-step explanation:
Given that:
The two different sizes of soda are:
Regular = 22 ounce
Large = 62 ounce.
The objective is to determine by what percent does the amount of the soda increase between the different soda size.
i.e. The ratio of the larger size in respect to the regular size:
So,
62/22 = 2.82
Thus in percent, the amount of the soda increase between the different soda size = 2.82 × 100%
= 282 percent
To the nearest percent, it is = 280

32 is 56% of what number?
Answer:
About 57.14285714, or 57 1/7 (400/7)
Step-by-step explanation:
Suppose the answer is x. This would mean that x multiplied by 0.56 (56%) would equal 32. To isolate x, you would have to divide both sides by 0.56, making the answer 32/0.56, or About 57 and 1/7

Step-by-step explanation:
From the Pythagorean Theorem
a^2 + b^2 = c^2
a = 1
b = ?
c = 2
1^2 + b^2 = 2^2
1 + b^2 = 4
b^2 = 4 - 1 = 3
b = sqrt(3)
Tan(30) = opposite / adjacent.
adjacent = sqrt(3)
Tan(30) = 1/sqrt(3)

the points on the table lie on a line FInd the slope of the line (x- (-2), 0, 2, 4) (y- 3,4,5,6)
Answer:
Slope= 1/2
Step-by-step explanation:
The slope of the given line is 0.5.
What is the slope of the line?The slope of a line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
The points on the table lie on a line, as follows;
x: (-2), 0, 2, 4
y: 3,4,5,6
To determine the slope of a line, you can use the formula:
(change in y)/(change in x)
As per the points in the table,
the change in x is (4-(-2)) = 6, and the change in y is (6-3) = 3.
Slope = (3)/(6)
Slope = 1/2
Apply the division operation, and we get
Slope = 0.5
Therefore, the slope of the line is 0.5.
