Answers

Answer:

The Answer is 2 blue marbles.

Step-by-step explanation:

The numbers of blue marbles in the bag will be 2.

What is proportion ?

A proportion is an equation based on the equality of two ratios.

Here it is given that :

a bag contains = 10 red marbles

the ratio of red marbles to blue marbles is = 5:1

That is :

5 ratio of marbles is equals to = 10 marbles

now,

1 ratio of marbles is equals to = 2 marbles

Therefore, the numbers of blue marbles in the bag will be 2.

Answers

Answer:

1. x = 7

2. x = -5

Step-by-step explanation:

1. Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: 2*x+5*(6*x-9)-(179)=0

Pull out like factors 6x - 9 = 3 • (2x - 3)

(2x + 15 • (2x - 3)) - 179 = 0

Pull out like factors: 32x - 224 = 32 • (x - 7)

Solve: x-7 = 0

Add 7 to both sides of the equation = 7

2. Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: -40-(6*x-5*(-4*x-18))=0

Pull out like factors: -4x - 18 = -2 • (2x + 9)

-40 - (6x - -10 • (2x + 9)) = 0

Pull out like factors: -26x - 130 = -26 • (x + 5)

-26 • (x + 5) = 0

Solve: x+5 = 0

Subtract 5 from both sides of the equation: x = -5

What is the solution to 0.3(12x - 16) = 0.4(12 - 3x)?

Answers

Step-by-step explanation:

The solution is one-solution

.3(12x-16)=.4(12-3x) (you do the distributive property)

3.6x-4.8=4.8-.12x (you add 1.2 to both sides)

3.6x-3.6=4.8 (You add 3.6 to both sides)

3.6x=8.4 ( You divide 3.6 both numbers)

Joe can run 12 miles in 125 minutes. How many miles can he run in 230 minutes? (solve and explain the steps)

Answers

Answer:

Joe will run 22.08 miles in 230 minutes.

Step-by-step explanation:

Given that Joe can run 12 miles in 125 minutes.

so Joe running the miles in 1 minute is = 12/125 = 0.096 miles

unit rate = 0.096 miles/per minute

As Joe runs 0.096 miles in one minute.

Thus, in 230 minutes, Joe will run = 0.096 × 230 = 22.08 miles

Therefore, Joe will run 22.08 miles in 230 minutes.

The best estimate of the average rate of change for the function graphed over the interval 1 ≤ x ≤ 3 is 3.

What is Average Rate of Change of a Function?

Average rate of change of a function is defined as the rate at which the value of the function is changing with respect to the change in the input values.

The interval given is 1 ≤ x ≤ 3.

The graph of the function is given below.

It can be clearly seen that,

The y value corresponding to x = 1 is y = f(1) = 2.

So one point on the graph is (1, 2).

The y value corresponding to x = 3 is y = f(3) = 8.

So the other point on the graph is (3, 8).

Average rate of change over 1 ≤ x ≤ 3 = [f(3) - f(1)] / [3 - 1]

= [8 - 2] / [2]

= 6/2

= 3

Hence the best estimate for the average rate of change of function over the interval 1 ≤ x ≤ 3 is 3.
