Step-by-step explanation:

To find 60% of people you just multiply .6 with the number you are trying to find 60% of. Like 100. 100 times .6 = 60.

Step-by-step explanation:

$ 3750 = truck rental; $125 per ton of sugar transported

C is cost; S is number of tons transported

Equation relating C to S would be a linear equation like y = mx + b

C = 125S + $3750

This equation would be graphed in the first quadrant only

you would start with your y-intercept at (0, 3750)

As x increases by 1, your y increases by 125 yielding these points:

(1, 3875) (2, 4000) (3, 4125) etc.

This shows that for each increase by one ton of sugar, the cost goes up $125

Answer:

$b=3A-a-c$

Step-by-step explanation:

$A=\frac{a+b+c}{3}$

Multiply both sides by 3

$3A=a+b+c$

Add $-b-c$ both sides

$3A-a-c=b$

$b=3A-a-c$

The length of a rectangle is represented by (2x2−5x+5)cm and the width is represented by (x2+4x−3)cm. What is the representation

Katarina [22]

Answer: $6x^2-2x+4$

Step-by-step explanation:

Given

The length of a rectangle is given by

$l=2x^2-5x+5$

and the breadth is given by

$w=x^2+4x-3$

Perimeter is the sum of the sides of rectangle

$\therefore \text{Perimeter P= }2(2x^2-5x+5+x^2+4x-3)\\\Rightarrow P=2(3x^2-5x+4x+5-3)\\\Rightarrow P=2(3x^2-x+2)\\\Rightarrow P=6x^2-2x+4$

Thus, the perimeter is given by $6x^2-2x+4$ .
