Answer: 125 minutes to make tests for five classes, $2388 in two months, and 4800 women to 3,600 men

1 class: 25 minutes

5 classes: [tex]25[/tex] × [tex]5[/tex] [tex]= 125[/tex] minutes

[tex]\frac{3582}{3}=\frac{x}{2}[/tex]

[tex]\frac{7164}{3}=\frac{3x}{3}[/tex]

[tex]2,388 = x[/tex]

[tex]x= 2,388[/tex]

[tex]\frac{8}{6}=\frac{x}{3600}[/tex]

[tex]\frac{28,800}{6} =\frac{6x}{6}[/tex]

[tex]4,800=x[/tex]

[tex]x=4,800[/tex]

Answer: n = 27

Step-by-step explanation: n in (-oo:+oo)

(1/3)*n = 9 // - 9

(1/3)*n-9 = 0

1/3*n-9 = 0 // + 9

1/3*n = 9 // : 1/3

n = 9/1/3

n = 27

Answer:

50

Step-by-step explanation:

180 - 90+40 = 50

Answer:

Answer: 50 degrees

Step-by-step explanation:

using this knowledge, you can make the following equation:

90 + 40 + x = 180

130 + x = 180

now subtract 130 from both sides.

x = 180 - 130

x = 50°

$ 410

hi there !

80% ................. $328

100% .................$ x

x = 100×328/80

= 32800/80

= $ 410

Good luck !

Answer:

x+3/5

Step-by-step explanation:

f(x)=x-3/5

y=f(x) let

y=x-3/5

put x at y and y at x

then,

x=y-3/5

y=x+3/5

f(x) inverse is x+3/5

Answer:

there are no solutions

Step-by-step explanation:

HERE ARE THE STEPS IN CASE U NEED EM :)

Step 1: Simplify both sides of the equation.

−8(n+5)=−44−8n

(−8)(n)+(−8)(5)=−44+−8n(Distribute)

−8n+−40=−44+−8n

−8n−40=−8n−44

Step 2: Add 8n to both sides.

−8n−40+8n=−8n−44+8n

−40=−44

Step 3: Add 40 to both sides.

−40+40=−44+40

0=−4

Answer:

D) Emerson must earn at least a 94 on his final test to earn an “A” in his class

Step-by-step explanation:

We calculate this using mean in this format:

Test Scores / # of Test ≥ 90 (which is an A)

Substitute:

(92 + 86 + 88)+ x / 4 ≥ 90

Add:

266 + x / 4 ≥ 90

Get Rid of the Denominator:

(4) 266 + x / 4 ≥ 90 (4)

Multiply:

266 + x ≥ 360

Isolate x (Subtract 266 From Both Sides):

x ≥ 94

This means that x (His final test score) has to be greater than (above) or equal to 94. A term for greater than or equal to is “at least.” Hope this helps :)

Answer:

it is in this order

Step-by-step explanation:

D E A B C your welcome! and good luck

[tex]x + y = 6y[/tex]

Subtract the sides of the equation minus 6y

[tex]x + y - 6y = 0[/tex]

[tex]x - 5y = 0[/tex]

[tex] - 5y + x = 0[/tex]

[tex]a = - 5[/tex]

[tex]b = 1[/tex]

[tex]c = 0[/tex]

Answer:

60 seconds.

Step-by-step explanation:

We have been given that Maria train can go around the track in 10 seconds. Alma train can go around the track in 12 seconds.

To find the number of seconds after which both trains will cross the finish line together the first time we will find LCM of 10 and 12. LCM will give us the smallest positive integer that is divisible by both 10 and 12.  

Multiples of 10 are: 10, 20, 30, 40, 50, 60, 70,...    

Multiples of 12 are: 12, 24, 36, 48, 60, 72, 84,..  

We can see that least common multiple of 10 and 12 is 60, therefore, it will take 60 seconds for both trains to cross the finish line together the first time.

Answer: 9 years

Step-by-step explanation:

Simple interest = PRT/100

where

P = principal = $2450

R = rate = 3.5%

T = time = unknown

Interest = $3221.75 - $2450 = $771.75

Simple interest = PRT/100

$771.5 = ($2450 × 3.5 × T)/100

$771.5 = $8575T/100

8575T = 771.5 × 100

8575T = 77150

T = 77150/8575

Time = 8.99 years = 9 years

Answer:

x=9

Step-by-step explanation:

2/3x-1=5

Add 1 to each side

2/3x-1+1= 5+1

2/3x = 6

Multiply each side by 3/2

2/3x*3/2 = 6*3/2

x = 9

Answer:

x=9

Step-by-step explanation:

You add one to both sides, multiply 3 to both sides (to further isolate x), and then divide by 2 on both sides. When you substitute back in, both sides of the equation are equal to each other.

The value of n that makes the equation [tex](13 + 4i) + n = 0[/tex] true is (d) -13 - 4i.

The equation is given as:

[tex](13 + 4i) + n = 0[/tex]

Remove brackets

[tex]13 + 4i + n = 0[/tex]

Subtract 13 from both sides

[tex]13 - 13 + 4i + n = 0 - 13[/tex]

Evaluate like terms

[tex]4i + n = - 13[/tex]

Subtract 4i from both sides

[tex]4i -4i + n = - 13 -4i[/tex]

Evaluate like terms

[tex]n = - 13 -4i[/tex]

The equation cannot be further simplified.

Hence, the value of n is (d) -13 - 4i

Answer:

first one D (–13 - 4i)

second B (1)

on egde

Step-by-step explanation:

Answer:

The fractions are not equivalent. If you cross multiply 65 x 2 = 130 and 4 x 13 = 52. 130 > 52. Set them as a proportion. [tex]\frac{65}{4} = \frac{13}{2}[/tex]

They are not equal.

For 65/4 you cannot divide it by 2 and then get 13/2. You would get 32.5/2.

32.5/2 is not equal to 13/2

Start at (0,0). To get to the other point, you must move up 8 units and move to the right 6 units.

slope = rise/run = (change in y)/(change in x) = 8/6

Or you could use the slope formula

m = (y2-y1)/(x2-x1)

m = (8-0)/(6-0)

m = 8/6

Normally I would reduce, but your teacher has decided not to.

8/6 reduces to 4/3 when you divide both parts by 2.
