= X/5+7/10-7/10=2.3-7/10
=x/5=1.6
X=8

Answer:

d) 13.11

Step-by-step explanation:

Forming the equation,

→ x ÷ 5.7 = 2.3

Now the value of x will be,

→ x ÷ 5.7 = 2.3

→ x = 2.3 × 5.7

→ [ x = 13.11 ]

Hence, the answer is 13.11.

Step-by-step explanation:

Suppose you are solving a real-world problem that contains fractions, mixed numbers, percents, and decimals. Why might it be helpful to convert all the values to one form? How would you determine which form to use?

Answers

It might be helpful to convert all the values to one form because:

1. You can't easily add or subtract values that are in a different form.

2. It is easier to visualize when working with greater than/less than problems.

______________________

I would determine which form to use based on the problem. For example, when dealing with dividing up slices of pie, it would be easiest for me to use fractions or mixed numbers, while in a problem involving how many blue buttons are in a bag of multicolored buttons it would be easiest for me to use percentages.

The total feet of fencing needed to cover the entire right-angle triangle will be 24 feet thus, option (B) is correct.

What is a triangle?

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.

As per the given,

The right angle triangle has been formed below,

The smaller side = 6 feet (base)

Bigger side = 10 feet (hyp)

By Pythagoras' theorem,

x = √(10² - 6²) = √64 = 8 feet

Therefore,total fencing = 6 + 10 + 8 = 24 feet.

Hence "The total feet of fencing needed to cover the entire right-angle triangle will be 24 feet".

What is equation modelling? What is a mathematical equation? What is the general equation of a straight line?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.The general equation of straight line is -

        y = mx + c

        for c = 0

       y = mx

        This represents the direct proportionality. Here, m is constant and -

        [m] = Δy/Δx, represents the rate of change.

Given is a linear graph as shown.

We can find the rate of change as -

m = (0 - 7)/(8 - 0)

m = -7/8

m = - 0.875

Therefore, the rate of change will be m = - 0.875.

I think that you divide those numbers
Since it’s takes 4 hours in 240 minutes you have to divide those numbers to get miles per hour. The answer is simple. Just imagine it’s like 24 divided by 4. What is it? It’s 6. But since it’s 240 not 24 it would be 60. So that means it’s 60 miles per hour. So divide 90 by 60 and get 1.5 or 1 and a half miles in fraction form. So it’s D.

Answers

Answer:

A and C

Step-by-step explanation:

Step 1: Replace x with 2.5 and see if it makes the equation correct.

A. |2 1/2 + x = 5| Since 2 and 1/2 is also written as 2.5, and 2.5+2.5=5, the solution makes this equation true.

B. |25x = 63| 25 x 2.5 equals 62.5, which does not make this equation true because 63 ≠ 62.5

C. |6.75x + 4.25x = 27.5| I Rewrite this equation as

(6.75 x 2.5) + (4.25 x 2.5) which can simplify to 16.875 + 10.625 and it does in fact equal 27.5, so this solution does make the equation true.

Step 2: Eliminate the equation(s) that aren't true, and then answer.

A and C are correct.

Cameron has 75% as many shirts as her brother. How many shirts does her brother have if Cameron has 9 shirts?

A. 3 shirts
B. 9 shirts
C. 12 shirts
D. 16 shirts

Answers

Answer:

The number of shirts that Cameron's Brother has is:

C. 12 Shirts

Step-by-step explanation:

Cameron has 75% as many shirts as her brother.

let the number of shirts Cameron has be= C

let the number of shirts Cameron's brother has be= B

Then, C=9 (Given)

Since,

Cameron has 75% as many shirts as her brother.

So,

     C=75/100 X B

     9=75/100 X B

     9X100/75=B

     B=9X100/75

     

75/100 can be reduced to the fraction 3/4,

                                                                     as 75= 25X3 and 100=25X4

Thus,

          B=9X100/75

          B=9X4/3

3 cancels 9 to leave 3,

Thus,

          B=3X4

          B=12

So,

     Answer=12 Shirts

      Number of shirts that Cameron's Brother has are 12

The answer is c: 12 shirts
