What is an equivalent expression for 4(2m + n)

Answers

Answer:

8m+4n

Step-by-step explanation:

4(2m+n)

you have to distribute 4 to 2m and n

so your answer will be

8m+4n

Hope this helped :))

Answer:

8m + 4n

Step-by-step explanation:

To find the answer, you should distribute the 4 on the outside of the parentheses to each of the terms inside the parentheses, which would get: 4(2m) + 4n.

Simplify 4(2m) by multiplying, which gets 8m.

The equation is then 8m + 4n, which cannot be added together because the variables are different.

x=64/2

x=32

Your friends shuffle the cards and then deal them. Select probability of getting a red card. Select probability of getting a spade card.

Answers

Answer:

1/2 ; 1/4

Step-by-step explanation:

Number of cards in a deck = 52

Number of red cards = 26

Number of spades = 13

Probability of event A :

P(A) = required outcome / Total possible outcomes

P( red card) = number of red cards / total cards in deck

P(red card) = 26 / 52 = 1/2

P(spade) = number of spades / total cards in deck

P(red card) = 13 / 52 = 1 / 4

Answers

Answer:

b=3, y=6

Step-by-step explanation:

Label the 2 equations:

2b +6y= 42 -----(1)

2b +4y= 30 -----(2)

(1) -(2):

(2b +6y) -(2b +4y)= 42 -30

2b +6y -2b -4y= 12

2y= 12

y= 12 ÷2 (÷2 on both sides)

y= 6

Susbt. y=6 into (2):

2b +4(6)= 30

2b +24=30

2b= 30 -24 (-24 on both sides)

2b= 6

b= 6 ÷2

b= 3

Answer:

y = 6, b = 3

Step-by-step explanation:

Since both equations have 2b in them, subtracting them gets you a quick result because the 2b-2b cancels out!

2b + 6y = 42

2b + 4y = 30

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

       2y = 12

         y = 6

Then 2b = 42 - 36 = 6, so b = 6/2 = 3

A chemist has a mixture with a temperature of 3.5°C. Then the chemist cools the mixture. The temperature changes by -14.2°C. What is the temperature of the mixture after it cools? Show your work.

Answers

Answer:

-10.7°C

Step-by-step explanation:

The change in the temperature is the difference between the initial  temperature and the final temperature. Let the initial temperature be T1 and the final be T2 then the change in temperature will be

= T2 - T1

Hence

-14.2 = T2 - 3.5

T2 = -14.2 + 3.5

= - 10.7°C

The temperature of the mixture after it cools is -10.7°C

Coffee café mix 90 pounds of coffee that cost six dollars per pound the types of coffee used to make this makes you cost seven dollars and four dollars per pound how many pounds of the seven dollar per pound coffee should be used in this mixture

Answers

Answer:

y =  60

Step-by-step explanation:

From the  information we get:

x  quantity of 4 dollars  coffee used in the mix

y  quantity of 7 dollars  coffee used in the mix

For the quantity of coffee to be sold a 7 $/pound  ( 90 pounds)

Then  6*90  =  540  $

Therefore

x  +  y  =  90     and

4*x  +  7*y  =  540

A two equations system we solve for x and y

y =  90  -  x

4*x  +  7* ( 90  -  x ) = 540

4*x  +  630 - 7*x  =  540

- 3*x  =  - 90

x = 30 pounds   and

y  =  90  -  30

y  =  60

We should use  60 pounds of the seven $ coffee

A school chorus has 90 sixth-grade students and 75 seventh-grade students. The music director wants to make groups of performers, with the same combination of sixth- and seventh-grade students in each group. She wants to form as many groups as possible.

Answers

Answer:

The music director could make 15 groups of performers with 6 6th grade students and 5 7th grade students in each group.

Step-by-step explanation:

Since in the question it is mentioned that

There is 90 6th grade students and 75 7th grade students

Now factor could be done in the following ways

90 = 2 × 45 = 2 × 3 × 15 = 2 × 3 × 3 × 5

75 = 3 × 25 = 3 × 5 × 5

Now the GCF of 90 and 75 is

= 3 × 5

= 15

So,

90 = 15 × 6

75 = 15 × 5

Hence, The music director could make 15 groups of performers with 6 6th grade students and 5 7th grade students in each group.

6) 23F-17=29
7) 2(3G+4)=56
8) H+9=0
9) 3(K-8)=96
10) 5M-5=0

Answers

Answer:

f = 2

g = 8

h = -9

k = 40

m = 1

Step-by-step explanation:

Equation 1:

23f - 17 = 29

Add 17 to both sides. This undoes the -17.

23f = 29 + 17

Add 17 to 29 to get 46.

23f = 46

Divide both sides by 23. This undoes the multiplication by 23.

f = 46/23

Divide 46 by 23 to get 2.

f = 2

Equation 2:

2(3g + 4) = 56

Divide both sides by 2. This undoes the multiplication by 2.

3g + 4 = 56/2

Divide 56 by 2 to get 28.

3g + 4 = 28

Subtract 4 from both sides. This undoes the +4.

3g = 28 - 4

Subtract 4 from 28 to get 24.

3g = 24

Divide both sides by 3. This undoes the multiplication by 3.

g = 24/3

Divide 24 by 3 to get 8.

g = 8

Equation 3:

h + 9 = 0

Subtract 9 from both sides. This undoes the +9.

h = 0 - 9

Any number subtracted from 0 gives its negation.

h = -9

Equation 4

3(k - 8) = 96

Divide both sides by 3. This undoes the multiplication by 3.

k - 8 = 96/3

Divide 96 by 3 to get 32.

k - 8 = 32

Add 8 to both sides. This undoes the -8.

k = 32 + 8

Add 8 to 32 to get 40.

k = 40

Equation 5:

5m - 5 = 0

Add 5 to both sides. This undoes the -5

5m = 0 + 5

Anything plus 0 gives itself.

5m = 5

Divide both sides by 5. This undoes the multiplication by 5

m = 5/5

Anything divided by itself gives you 1.

m = 1

3x + 7 = y-5
trying to find y

Answers

Answer: Simplifying

3x + 7 = y + -5

Reorder the terms:

7 + 3x = y + -5

Reorder the terms:

7 + 3x = -5 + y

Solving

7 + 3x = -5 + y

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-7' to each side of the equation.

7 + -7 + 3x = -5 + -7 + y

Combine like terms: 7 + -7 = 0

0 + 3x = -5 + -7 + y

3x = -5 + -7 + y

Combine like terms: -5 + -7 = -12

3x = -12 + y

Divide each side by '3'.

x = -4 + 0.3333333333y

Simplifying

x = -4 + 0.3333333333y
