Write an equivalent expression for -6(-7+2z)
Explain in full steps

Answers

Answer 1

Answer:

42 - 12z

Step-by-step explanation:

We can find an equivalent expression by using distributive property

Distributive property: whenever there is a number outside of the parenthesis you multiply that number by whatever is in the parenthesis

So for -6(-7+2z) we would multiply the number outside of the parenthesis (-6) by what's inside of the parenthesis ( -7 and 2z )

-6 * -7 = 42

-6 * 2z = -12z

An equivalent expression would be 42 - 12z

Answer 2
42-12z

-6(-7+2z)
42-12z

Answers

Answer:

Jacob is 4 years old and his mother is 40 years old.

Step-by-step explanation:

Part 1: The linear equations are  and

Part 2: Solving the equations, we have,  and

Part 3: Jacob is 4 years old and his mother is 40 years old.

Explanation:

Part 1: Let j represent Jacob's age, and let m represent his mother's age.

It is given that, "Jacob's mother is three more than nine times as old as Jacob". Writing it as linear equation, we have,

It is also given that, "In eleven years, his mother will be five more than three times his age". Writing it as linear equation, we have,

Simplifying this, we get,

Thus, the linear equation is

The linear equations are   and

Part 2: Solving the linear equation, we get,

Substituting  in

Simplifying, we get,

Hence,

Substituting  in

Solving the equations, we have,  and

Lacy usually feeds 20 puppies at the shelter. How many ounces of food would 20 puppies need? (image attached)

Answers

Answer:

560

Step-by-step explanation:

140 ÷ 5 = 28

28 x 20 = 560

please mark me as brainliest and correct me if im wrong

You could either use the propotional method or unitary method, but I am going to be using the porpotional method since it is more quick.

Step 1

So first we would convert  the numbers givin into a fraction by putting 5 over 140 and 20 over x which is the question mark.

Step 2

Then we would cross multiply, so multiply numbers that are diagonal to each other .140 would multiply with 20 and 5 would multiply with x.

Step 3

After we multiply (we do not multiply 5 with anything so it is just 5)we would have the equation , x times 5=2800. Since  we need to isolate x we would take 5 and put it under 2800 so it would be 2800 divided by 5.

Step 4

After we divide 2800 by 5 we would have 560 which equals to x , making it the ounces needed to feed 20 animals at the shelter .

Summarise

To briefly explain this the way to find the answer would be 20x40 divided by 5.

Hope this helped :D

The sum of two consecutive integers is -92. Find the integers.

Answers

Answer:

x = -46.5

x + 1 = -45.5

Step-by-step explanation:

x + x + 1 = -92

2x + 1 = -92

      -1       -1

------------------

   2x = -93

   ----     ----

    2        2

   x = -46.5

x + 1

(-46.5) + 1

-45.5

Answer:

No solution

Step-by-step explanation:

We can set up an equation where x is the integer and x+1 is the next one

x+x+1=-92

2x+1=-92

2x/2=-93/2

x=-46.5

-46.5+1=-45.5

The problem is that integers do no include decimals so there is no possible whole number. This problem would be possible if it was consecutive odd integers.

Please help me i tried to do this but I really don't get this can somebody help? plsssssssssssssssssssssssssssssss(sorry for spam)

Answers

I’m not entirely sure how to answer this without a word problem, but from what I see, all you have to do is multiply the two numbers.
12 x 43= 516
5 x 88 = 440
8x 63= 504
7 x 28= 196
Usually, when you see a number followed by another number in parentheses, like here, that means to multiply.
12(43)=516
5(88)=440
8(63)=504
7(28)=196

What is the value of the expression shown below? 7 + (10 - 4 )^2 divided 4 x (1/2)

Answers

i’m pretty sure 21.5 because you do what is in parentheses first which is 10-4=6, then you square to equal 36 then add 7=43 and divide by 2 bc 4(1/2) is 2 and you get 43/2 which is 21.5

Answer:

43 / 2  = 21  1/2 = 21.5

Step-by-step explanation:

7+(10-4)^2/ 4 (12)        you can either multiply by  4(1/2)/4(12) or do the following

Subtract 4 from 10 to get 6.

7+6^2 / 4×(  1/2)  

Calculate 6 to the power of 2 and get 36.

7+36 / 4×(  1/2  )  

Add 7 and 36 to get 43.

43 / 4× 1/2  

 Multiply 4 and    1/2   ​ to get 2.

43 / 2  = 21  1/2 = 21.5

The dot plots below show the test scores of some mathematics students and some science students: Two dot plots are shown one below the other. The top and the bottom plots have the title Mathematics Students and Science Students respectively. Below the line for each dot plot is written Mark. The markings on each line are from 30 to 50 at intervals of 1. For the top plot there are two dots each for 34 and 40 and 1 dot each for 32, 33, 35, 37, and 39. For the bottom plot there are 2 dots each for 43, 46 and 49 and 1 dot each for 41, 42, and 47. Based on visual inspection of the dot plots, which group of students appears to have the larger average score? The mathematics students The science students Both groups are similar. Not enough information is available to draw a conclusion.

Answers

Answer:

Science students

When you find the average both plots using median, mean, or interquartile range, you will find that the score for the science students will always be greater than the score of the mathematics students. This is because none of the mathematics students scored higher than the science students, so the mean will always be greater.

MATHEMATICS :

Plot interval = 30 to 50

MEAN :

(34*2) + (40*2) + (32*1) + (33*1) + (35*1) + (37*1) + (39*1) = 324

Sample size, n = (2 + 2 + 1 + 1 + 1 + 1 + 1) = 9

Mean = 324 / 9 = 36

BOTTOM :

SCIENCE :

MEAN : (43*2)+(46*2)+(49*2)+(41*1)+(42*1)+(47*1) =

406

SAMPLE SIZE = (2 + 2 + 2 + 1 +1 +1) = 9

406 / 9 = 45.111

Fergus has 3 1/4 cups of oats

Therefore cups of oats left = 13/4 - 8/3

= 39/12 - 32/12

= 7/12 cups of oats left

She borrowed 1 cup of oats from neighbour

7/12 + 1/1

Why are the divisibility rules for 2, 3, and 5 very useful for determining prime and composite numbers

1. They are the smallest odd numbers
2. They add up to 10
3. They are prime numbers with nice divisibility rules
4. They multiply to 30
5. They can be multiplied together to make every number

Answers

Answer:

option 3.

Step-by-step explanation:

alright, ima explain each option.

1. "smallest odd numbers" 2 is an even number. that's out of the playing field.

2. "add up to 10" sure, they do add up to 10, but finding prime and composite numbers are all about division and multiplication.

3. this is true. 2, 3, and 5 are all prime numbers, and they have the nice divisibility rules. [ for 2, it has to be even, for 5, it has to end in 0 or 5, and 3 has to have the sum of its digits being divisible by 3. ]

4. they do multiply to 30, but this does not help break the composite numbers down.

5. we cannot make every number with just these. we can not multiply any other whole number to get 7 for per example, because it's a prime number.
