30 kilograms of beans costs $5. How many kilograms of beans can you buy for $20?

Answers

Answer:

120 kg

the kilograms of beans which can by for $20 are

30*(20/5) = 30.4 = 120 (kg)

Answer: 120 kilograms

Step-by-step explanation:

We can buy 30 kilograms of beans for $5 dollars. We need to find how many kilograms of beans we can buy for $20.

The first step is to divide 20 by 5. Then, using the quotient, we can multiply it by 30 to see how many kilograms of beans we can buy for $20.

20 ÷ 5 = 4.

4 x 30 = 120.

Therefore, we can buy 120 kilograms of beans for $20.

Cool beans ;)

(25m + 22) + (9m) = ?​

Answers

Answer:

Step-by-step explanation:

Simplifying

25m + 22 = 9m

Reorder the terms:

22 + 25m = 9m

Solving

22 + 25m = 9m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-9m' to each side of the equation.

22 + 25m + -9m = 9m + -9m

Combine like terms: 25m + -9m = 16m

22 + 16m = 9m + -9m

Combine like terms: 9m + -9m = 0

22 + 16m = 0

Add '-22' to each side of the equation.

22 + -22 + 16m = 0 + -22

Combine like terms: 22 + -22 = 0

0 + 16m = 0 + -22

16m = 0 + -22

Combine like terms: 0 + -22 = -22

16m = -22

Divide each side by '16'.

m = -1.375

Simplifying

m = -1.375

A line that includes the points (-9, h) and (-8, 9) has a slope of 10. What is the value of h?

Answers

Answer:

-1

Step-by-step explanation:

Use the rule y2-y1 / x2-x1

y1 = h

y2 = 9

x1 = -9

x2 = -8

so you get

9-h / (-8) - (-9) = 10

cross multiply to get

9-h = 10

so -h = 10-9

so h = -1

Given that L is a linear function, L (5) = 100 and L (9) = 150.
a. Determine the value of L (13)

Answers

Answer:

L(13) = 200

Step-by-step explanation:

Linear function:

A linear function has the following format:

[tex]y = mx + b[/tex]

In which m is the slope(how much y changes when x changes by 1) and b is the y-intercept(value of y when x = 0).

Finding the slope:

L (5) = 100 and L (9) = 150.

The slope is given by the change in the output(L, which is equals to y in the general formula) divided by the change in the input(x).

Change in the output: 150 - 100 = 50

Change in the input: 9 - 5 = 4

Slope: [tex]m = \frac{50}{4} = 12.5[/tex]

So

[tex]y = 12.5x + b[/tex]

L (5) = 100

So [tex]y(5) = 100[/tex], which means that when [tex]x = 5, y = 100[/tex], and we use this to find b.

[tex]y = 12.5x + b[/tex]

[tex]100 = 12.5*5 + b[/tex]

[tex]b = 100 - 12.5*5[/tex]

[tex]b = 37.5[/tex]

So

[tex]L(x) = 12.5x + 37.5[/tex]

a. Determine the value of L (13)

L when [tex]x = 13[/tex]. So

[tex]L(13) = 12.5*13 + 37.5 = 200[/tex]
