Answer:

question 4. The right answers are 1,3 and 4

Question 5. No they are not balanced.

Step-by-step explanation:

1.

7/9 * 8 = 6  2/9

56/9 = 6 2/9

2.

8 + 11.5 = 20.5

19.5 ≠ 20.5

3.

23.42 - 8 = 15.42

15.42 = 15.42

4.

11 * 8 = 88

88 = 88

5.

40/8 = 6

40/8 ≠ 6

Answer:

181m - 38

Step-by-step explanation:

Hey there!

9(20m – 5) + (m + 7)

DISTRIBUTE

9(20m) + 9(–5) + m + 7

9(20m) + 9(–5)

9(20m) = 180m

9(–5) = -45

NEW EQUATION: 180 – 45 + m + 7

COMBINE your LIKE TERMS

(180m + m) + (–45 + 7)

“m” itself is understood as an invisible 1!

180m + m = 181m

–45 + 7 = –38

NEW EQUATION: 181m – 38

ANSWER: 181m – 38 ☑️

Good luck on your assignment and enjoy your day!

Answer:

$4750

Step-by-step explanation:

Simple interest is the interest calculated on the principal at a given rate for a time period.

The simple interest formula is given as,

SI = P x R x T / 100

P = principal

R = rate

T = time

Amount = SI + P

The amount Bertha will have in his account after 50 years is $4750.

Simple interest is the interest calculated on the principal at a given rate for a time period.

The simple interest formula is given as,

SI = P x R x T / 100

P = principal

R = rate

T = time

We have,

P = $1000

T = 50

R = 7.5%

A = SI + P

SI = (1000 x 7.5 x 50) / 100

SI = 1000 X 7.5 X 50 / 1000

SI = $3750

A = SI + P

A = 3750 + 1000

A = $4750

Thus,

The amount Bertha will have in his account after 50 years is $4750.

Answer:

7

Step-by-step explanation:

First expand 2/3 (9x-6) = 4 (x+2)+ 2 By doing 2/3 (9x - 6)/3

Which gives you 2/3 (9x - 6)

Then you factor it 2/3 (9x - 6) 6 (3x - 2) get 6 (3x - 2) / 3

then you divide 6/3 with 2

Getting 2 (3x - 2)

The use the distributive law

2 x 3x - 2 x 2

simplify the equation

6x - 4

expand 4 (x +2) + 2:   4x + 10

which then equals 6x-4=4x+10

add 4 to both sides

6x-4+4=4x+10+4

simplify

6x=4x+14

subtract 4x from both sides

simplify again

2x=14

divide both sides by 2

2x/2 = 14/2

simplify one last time and get the answer

x=7

Answer:

9

Step-by-step explanation:

we know by definition that

[tex]f^{-1}(f(x))=x\\\\f^{-1}(\frac{2x}{3})=x\\\\f^{-1}(x)=ax\\\\f^{-1}(\frac{2x}{3})=a(\frac{2x}{3})=x\\\\f^{-1}(x)=\frac{3x}{2}[/tex]

so now we evaluate

[tex]f^{-1}(6)=\frac{3*6}{2}\\\\=3*3\\\\f^{-1}(6)=9[/tex]

and if we want to do an extra step

[tex]f^{-1}(f(6))=6\\\\f^{-1}(\frac{2*6}{3})=f^{-1}(4)=\frac{3*4}{2}=6[/tex]

which works.

Answer:

5 minutes

Step-by-step explanation:

let the time after which two lines will have filled an equal number of barrels is 'X' minutes.

so, according to the question after 'X' minutes;

⇒ number of barrels in old conveyer line = number of barrels in new conveyer line

⇒ 40x + 2X = 10X  

⇒ X = 5

Answer:

1/4

Step-by-step explanation:

First, since the numerator is 7 you want to see how many times you can divide that.

So, you can only divide 7 by 7 1 time so that turns into 1.

Hence, your numerator is now 1 and denominator stays the same so its..

Answer:

option 4

Step-by-step explanation:

put like terms on either side

9x + 2a = 3a - 4x

subtract both sides by 2a

9x = a - 4x

add both sides by 4x

13x = a

divide both sides by 13

x = a/13

please give thanks, hit that heart button :)

Answer:

4.) a/13

Step-by-step explanation:

9x + 2a = 3a - 4x

9x + 4x = 3a - 2a

13x = a

13x/13 = a/13

x = a/13

Answer:

82.8

Step-by-step explanation:

24/.29

=82.75862

but you want it rounded so 82.8 is your answer

I hope this helps

Answer:

82.8

Step-by-step explanation:

Step 1: If 29% of a number is 24, then what is 100% of that number? Set up the equation.

24 over 29% = Y over 100%

Step 2: Solve for Y

Using cross multiplication of two fractions, we get

29Y = 24 x 100

29Y = 2400

Y = 2400 over 100 = 82.76

If you round 82.76 to the nearest tenth you get 82.8.

Answer:

$246.75

Step-by-step explanation:

11.75 x 21 = 246.75

hope this helps <3

Answer:

If the student worked 21 hours this month, she will earn $246.75.

Step-by-step explanation:

Let [tex]x[/tex] equal hours.

If the student earns $11.75 per hour, we can represent this with the expression:

[tex]11.75x[/tex]

If she worked 21 hours this month, then:

[tex]x=21[/tex]

With that information, we can substitute [tex]21[/tex] for [tex]x[/tex] in the initial expression:

[tex]11.75(21)[/tex]

Multiply:

[tex]246.75[/tex]

Therefore, if the student worked 21 hours this month, she will earn $246.75.

-

We can check our work by setting the initial expression equal to our solution:

[tex]11.75x=246.75[/tex]

Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]11.75[/tex]:

[tex]x=21[/tex]

Since this quotient matches the number of hours she worked, our solution is correct!

Answer:

The answer would be option 2) 51 miles/3 gallons.

Step-by-step explanation:

First, every 17 miles needs 1 gallon. If you add 17 more miles, it'll be 34 miles and you'll need a 2nd gallon, so you can already eliminate options 3 and 4. If you add another 17 miles and a gallon, it'll give you 51 miles 3 gallons. Option 1 would not be the answer because if you did 3/51, you'll get a whole different answer in decimals. So the only other option to choose from is option 2.
