Answer:
$25.80
Step-by-step explanation:
you have to add 16.50 to -42.30
This balance is negative.
================================================================
Explanation:
Start with -42.30 and add on 16.50
-42.30+16.50 = -25.80 is the final balance
The negative balance means Marcos owes this amount of money to the bank. This is true even though he deposited $16.50; he would need to deposit another $25.80 to get out of debt (this is assuming that there aren't any other bank fees coming down the line).
We can think of -42.30+16.50 as 42.30-16.50, but then make the result negative since -42.30 has a larger absolute value compared to 16.50

Tyrell worked on
16 - 2(4 + 3x)
what do brackets mean ? they mean that this operation has to be done before everything else in the expression.
as this contains a variable, we cannot fully calculate it, true, but we need to keep this in mind and always treat the content of the brackets as one package.
so, whatever I do from the outside with one part of that package, I have to do also with all the other parts of that package.
so, the multiplication with -2 has to happen with both : 4 and 3x. not just with 4.
therefore, the correct simplification looks like
16 - 8 - 6x
8 - 6x or -6x + 8
Amelia multiplied correctly, but then made a mistake summing things up
10x - 3(4x + 1)
10x - 12x - 3
10x - 12x = -2x
I can't mix the pure constant -3 into the factors of x. that would be like the famous mixing of apples and oranges.
so, the result is
-2x - 3

Aria is ordering a taxi from an online taxi service. The taxi charges $4 just for the
pickup and then an additional $1.25 per mile driven. How much would a taxi ride
cost if Aria is riding for 2 miles? How much would a taxi ride cost that is m miles
long?
Answer:
Riding 2 miles = $6.50
Riding m miles: C = 1.25m + 4
Step-by-step explanation:
(1.25)*(2) + 4 = $6.50

Answer:
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

if you need 180g of flour for 24 cookies how much flour is needed for 200
Answer:
1500g
Step-by-step explanation:
First, divide 200 by 24 so that you can have a common ratio. This would get you 8.333... Then multiply 8.333... to 180. This would get you the answer of 1500 g. Hope this helps :)
The amount of flour to make 200 cookies will be 1500 grams.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
If you need 180g of flour for 24 cookies.
Let 'x' be the amount of flour. Then the ratio of the flour to cookies will be constant.
x / 200 = 180 / 24
x = 200 x 180 / 24
x = 1500 grams
The amount of flour to make 200 cookies will be 1500 grams.

The equation for line k can be written as 4x+7y=7. Line l includes the point (7,3) and is parallel to line k. What is the equation of line l?
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]
Give the slope-intercept form of the equation of the line that is perpendicular to –7x – 8y = 12 and contains P(–3, 1)
Answer:
(-7/8)
Step-by-step explanation:
the line is -7x -8y =12
its slope = -(-7/-8)= -7/8
it passes through P(-3, 1)
(y-1)=(-7/8)(x+3)
y-1 = (-7/8)x - 21/8
y = (-7/8)x -13/8

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

An airline gathers data on late departures and early arrivals over a month. It finds that the probability of a late departure is 12 percent, the probability of an early arrival is 27 percent, and the probability of both a late departure and an early arrival is 4 percent. Which equation shows how to correctly calculate the probability of a late departure or an early arrival? P(late departure or early arrival) = 0. 12 0. 04 P(late departure or early arrival) = 0. 12 0. 27 P(late departure or early arrival) = 0. 12 0. 27 â€" 0. 04 P(late departure or early arrival) = 0. 27 0. 04 â€" 0. 12.
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
What is probability?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.

whats is the difference between a factor and multiple
Answer:
a factor is a number that divides another number without leaving any remainder. , A multiple is a number that, when divided a certain of times by another number, no remainder is left.Step-by-step explanation:
Answer:
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.
