-k + 4(k + 1) = 2k
-k + 4k + 4 = 2k
-k + 4k - 2k = -4
(-1 + 4 - 2)k = -4

It is all about rounding.
To estimate the product, round each value to 1 significant figure. For example, 46.7 rounds to 50, and 31.7 rounds to 30. The estimate of the product will be the product of these rounded values: 50·30 = 1500.

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
Consider the expression 8ab+3b+16-4a How many terms are there , How many factors are in the first term , which term is a constant ?
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.
More about the ratio and the proportion link is given below.

The population of a nearby town dropped from 7,500 to 6,000 in one year.
What was the percent decrease in the town's population that year?
Answer:5,600 - 3,500 = 2,100
2,100 is what percent of 3,500?
2,100 = X*3,500
X = 2,100 / 3,500
X = .60 or 60%

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.
