Answer:

[tex]\huge\boxed{\dfrac{4}{7};\ \dfrac{5}{8};\ 0.7;\ 72\%}[/tex]

Step-by-step explanation:

Two ways.

1. Convert to the decimal:

[tex]\dfrac{4}{7}=4:7=0.\overline{571428}\\\\\dfrac{5}{8}=5:8=0.625\\\\0.7=0.7\\\\72\%=\dfrac{72}{100}=0.72[/tex]

therefore

[tex]0.\overline{571428}<0.625<0.7<0.72}[/tex]

[tex]\dfrac{4}{7};\ \dfrac{5}{8};\ 0.7;\ 72\%[/tex]

2. Convert to the fractions with common denominator.

[tex]\dfrac{4}{7};\ \dfrac{5}{8}\\\\0.7=\dfrac{7}{10}\\\\72\%=\dfrac{72}{100}=\dfrac{18}{25}[/tex]

[tex]LCD=7\cdot8\cdot5\cdot5=1400\\\\\dfrac{4}{7}=\dfrac{4\cdot200}{7\cdot200}=\dfrac{800}{1400}\\\\\dfrac{5}{8}=\dfrac{5\cdot175}{8\cdot175}=\dfrac{875}{1400}\\\\0.7=\dfrac{7}{10}=\dfrac{7\cdot140}{10\cdot140}=\dfrac{980}{1400}\\\\72\%=\dfrac{72}{100}=\dfrac{72\cdot14}{100\cdot14}=\dfrac{1008}{1400}\\\\\dfrac{800}{1400}<\dfrac{875}{1400}<\dfrac{980}{1400}<\dfrac{1008}{1400}[/tex]

therefore

[tex]\dfrac{4}{7};\ \dfrac{5}{8};\ 0.7;\ 72\%[/tex]

Answer:

The slope is 6/7

Step-by-step explanation:

The slope is equal to (y₂ - y₁)/(x₂ - x₁)

Point 1 is (-2,1)

Point 2 is (5,7)

((7) - (1))/((5) - (-2))

(7 - 1)/(5 + 2)

6/7

The slope is 6/7

Answer:

The distance they drive before they stop is 98 miles.

Step-by-step explanation:

Since Ken and Donna are supposed to drive a total distance of 131 miles from Baltimore, MD to Richmond, VA for the wedding. If the first part of the journey is supposed to be 65 miles more than the second part. Let the second part be x miles. So, the first part is x + 65 miles

Since the total distance covered is 131 miles,

x + x + 65 = 131

adding the x's, we have

2x + 65 = 131

subtracting 65 from both sides, we have

2x = 131 - 65

2x = 66

dividing both sides by 2, we have

x = 66/2

x = 33 miles.

So, for the first part the distance travelled is x + 65 miles, so, x + 65 = 33 + 65 = 98 miles.  So, the distance they drive before they stop is 98 miles.

Answer:

Slope is - 2 because The slope-intercept form is y=mx+b where m is the slope value. In the equation y=-2x , the m value is - 2 .

Answer:

x= -16

Step-by-step explanation:

-2x+5=37

-2x=37-5

-2x=32

x= -16

Answer:

x= -16

Step-by-step explanation:

The goal in this problem is to get X on one side by itself.

We know that the opposite of subtraction is addition and the opposite of multiplication is division.

so to get 5 over to the right side, we need to subtract.

-2x+5=37 >>-2x= 37-5= 32

your problem now reads -2x= 32

We still have -2 on the left side and we need it to go to the right side so that X is by  itself. The opposite of multiplication is division, so we will need to divide

-2x=32÷-2 >> x=-16

Answer:

[tex]\boxed {a = 6}[/tex]

Step-by-step explanation:

Solve for the value of [tex]a[/tex]:

[tex]3 - 6a = 9 - 6a[/tex]

-Take [tex]-6a[/tex] and add it to [tex]-6a[/tex]:

[tex]3 - 6a + 6a = 9 - 6a + 6a[/tex]

[tex]3 - a = 9[/tex]

-Subtract both sides by [tex]3[/tex]:

[tex]3 - 3 - a = 9 - 3[/tex]

[tex]\boxed {a = 6}[/tex]

Therefore, the value of [tex]a[/tex] is [tex]6[/tex].

Answer:

35/6

Step-by-step explanation:

The result of dividing 5/6 by 1/7 is 35/6.

Here, we have,

To divide fractions, we can use the following rule:

To divide one fraction by another, we multiply the first fraction by the reciprocal of the second fraction.

In this case, we have:

(5/6) ÷ (1/7)

To find the reciprocal of a fraction, we simply flip the fraction by swapping the numerator and denominator.

Therefore, the reciprocal of 1/7 is 7/1.

Now, we can rewrite the expression as a multiplication:

(5/6) * (7/1)

Multiplying the numerators and denominators:

(5 * 7) / (6 * 1)

Simplifying:

35/6

Therefore, the result of dividing 5/6 by 1/7 is 35/6.

s14.98 + 92

Step-by-step explanation:

In order to make an expression for this word problem, all you have to do is follow along the steps in the problem:

s14.98 represents how many shorts Michele bought and how much they cost

8 * 11.50 represents how many shirts she bought and what they cost, but we need to simplify, so

8 * 11.50 = 92

Therefore, by adding the shorts and shirt together, we get the expression:

s14.98 + 92

Actually Welcome to the Concept of the Indices and BODMASS rule,

according to the BODMASS rule, we must always give high priority to the, parentheses "()" ,hence we will solve the bracket index powers first,

this we get as

Answer:

This is really simple, here i'll explain:

Step-by-step explanation:

41.2 x 1.5=

count how many spaces are after the decimal point.

for example, 41.2 has 1 space after the decimal point. The decimal 1.5 also has 1 space after the decimal point. So if you add the spaces it would be 2 because 1 + 1 = 2

After that, take away the decimal point, and just multiply like you normally would.

412 times 15

this would be 6180

after you do the multiplication, you will add the decimal point.

The decimal point will go in between 1 and 8 because there were 2 spaces after the decimal point in the numbers, and if you add them it would be 2 spaces.

Hope this helps!

Answer:

41.2×1.5=61.8. because you always have to line up the decimals.

It means -2/7 is to the right of -4

Step-by-step explanation:

It goes 3 to the positive side

and one down side

Answer: 28

-9^2 - (-6)^2 + 3 - 20

so follow order of operations

P = parentheses

E = exponents

D = divide

M = multiply

A = add

S = subtract

since there are no parentheses, do exponents

-9^2 = 81

-6^2 = 36

so now its

81 - 36 + 3 - 20

now follow order of operations

81 - 36 = 45

45 + 3 - 20

3 - 20 = -17

45 + -17 = 28

so your answer is 28

C. $0.19 per KWH

Step-by-step explanation:

The given data are;

KWH   [tex]{}[/tex]               Billing

578   [tex]{}[/tex]                 $109.82

1,033   [tex]{}[/tex]               $196.27

1,475   [tex]{}[/tex]               $280.25

1,754   [tex]{}[/tex]               $333.26

Therefore, we have the rate of change, m, given as follows;

m =(Change in the amount paid)/(Change in the electric usage in the same period)

For the first and second month, the rate of change is therefore;

m = ($196.27 - $109.82)/(1,033 - 578) = $0.19 per kWH

Between the first and third month, the rate of change is given as follows;

m = ($280.25 - $109.82)/(1,475 - 578) = $0.19 per kWH

Between the first and fourth month, the rate of change is given as follows;

m = ($333.26 - $109.82)/(1,754 - 578) = $0.19 per kWH

Therefore;

The rate of change is constant and is $0.19 per kWH
