Answer:

[tex]4x+7y=49[/tex]

Step-by-step explanation:

If you don't want to go through the slope-intercept form, you can easily see that two parallel line have their x and y coefficients in the same ratio, in our case 4:7. Let the new line be, then, [tex]4x+7y=k[/tex] and state that passes through our point: [tex]4(7)+7(3) = k \rightarrow k=49[/tex]

Riding 2 miles = $6.50

Riding m miles: C = 1.25m + 4

Step-by-step explanation:

(1.25)*(2) + 4 = $6.50

- If a 20-gallon bathtub is draining at a rate of 2.5 gallons, the max will be 20 gallons. Since it is water/etc, you cannot have negative water, so the least amount will be 0. We now have 0 ≤ ? ≤ 20

- What variable do we use? We are talking about gallons, so we will use g (gallons remaining) to get our answer of a, which is  0 ≤ g ≤ 20

[Second one, aka #11] is d

- I made the system

s - 18 = t

12s = 10t + 32

- Because one sport (s) has 18 less than one technology (t), so s - 18 = t. 12 sport (12s) has 32 more than 10 technology (10t) so if you add 32 to technology, you will get sport (12s = 10t + 32 )

The equivalent expression of (5ab)^3/30ab^-7 is 25 a^2b^10/6.

An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

here, we have

to determine the equivalent expression:

The expression is given as:

(5ab)^3/30ab^-7

Expand the numerator

(5ab)^3/30ab^-7

= 125 a^3b^3/30ab^-7

Divide 125 and 30 by 5

(5ab)^3/30ab^-7

=25 a^3b^3/6ab^-7

Apply the law of indices

(5ab)^3/30ab^-7

=25 a^(3-1) b^(3+7) /6

Evaluate the exponent

(5ab)^3/30ab^-7

=25 a^2b^10/6

Hence, the equivalent expression of (5ab)^3/30ab^-7 is 25 a^2b^10/6.

Step-by-step explanation:

Answer:

the volume is 50

Step-by-step explanation:

The volume of a pyramid is found by using the formula V = lwh/3

If you multiply 3 5 and 10 you get 150

Dividing 150 by 3 gives you 50

Answer:

c

Step-by-step explanation:

The equation that shows how to correctly calculate the probability of a late departure or an early arrival is  P(L∪E)=0.12+0.27-0.04.

Probability of late departure P(L) = 0.12

Probability of early arrival P(E) = 0.27

Probability of both a late departure and an early arrival P(L∩E)= 0.04

Probability is the measurement of the likelihood of an event.

P(L∪E)=P(L)+P(E)- P(L∩E)

Where P(L∪E) is the probability of a late departure or an early arrival.

So, P(L∪E)=0.12+0.27-0.04

Hence, the equation that shows how to correctly calculate the probability of a late departure or an early arrival is  P(L∪E)=0.12+0.27-0.04.

Vertical opposite angles

Answer:

14.2

Step-by-step explanation:

Answer: $9.48 or $9.47

Step-by-step explanation:

Total is $11.50 so far, discount is 20%. Add tax later to make it a little more simple.

20% can be written as 20/100 then simplified down to 1/5 So, another way to get the discount is to just divided $11.50 by 5, which is, $2.30, subtract it from $11.50 you get $9.20 as the new total. Time for the tax,

3% or 3/100 can be written as 0.03. Using this we can find the new cost by multiplying $9.20, which is, approximately 0.28, Add it, you get $9.48 or $9.47 depending on whether or not it wants you to round.

Answer:

$1968

Step-by-step explanation:

I'm not sure how to explain the equation but substitute 1968 for a variable.

Answer:

$1968

Step-by-step explanation:

so if 3 dozen is 1476 you want to divide that so it would be 1476/3 which is 492 if you take 492 and multiply it by 4 you'll get 1968

Main Differences Between Factor vs Multiple

Let us further discuss the difference between factor and multiple in the table below.

Basis of Comparison Factor Multiple

Definition It is a figure that gives a specific or definite outcome when it divides another figure It is the product of two whole numbers.

Results Less than or equal to such a specific figure Greater than or equal to the given figure.

Numbers of Result Limited Unlimited or continuous

Operation involved Division (÷) Multiplication (×)

Illustration If A divides B, A is factor of B If A is divisible by B and C, A is a multiple of B and C.

Difference Between Factor and Multiple: Conclusion

In conclusion, multiple vs factor concept is distinctive because the former uses multiplication (×) as a method of operation while latter uses division (÷). However, these two operations can be used together in a given equation or mathematical problem to get an expected outcome.

Though these two concepts are mostly taught in the elementary classes, they are inevitable in the arithmetic circus. One must be grounded in them and be sure of how they are applicable in every relevant equation. The good thing is that this guide has shown you their meanings, how to apply them, and the key discrepancies.

First there are 4 terms. I think/believe that there are 3 factors in the first term. And the answer to the last question is 16 or term 3.

Step-by-step explanation:

I hope this helps, plz mark me as brainlyest anyways I hope you get a good score on your test!!

Answer:

a. There are 4 terms in the expression

b. There are 3 factors in the first term.

c. The constant is 16.

8ab + 3b + 16 - 4a

A term is any signed number, a variable, or a constant  multiplied by a

variable or variables.

Therefore, the terms are 8ab,  3b,  16, and -4a. The terms are 4 in numbers.

The first term is 8ab .The first term has the factors 8 , a and b. This means the first term have 3 factors.

The term that is a constant is 16
