Answer:

46.75

Step-by-step explanation:

55% × 85 = 46.75

If you don't know what 55% is in decimal then it is 0.55. You also do this way and will give you the same answer.

0.55 × 85 = 46.75

Hope this helps, thank you !!

Answer:

46.75.

55x + 148/24

Explanation:

Answer:

C

Step-by-step explanation:

The domain of this function is [tex][-4,2][/tex], as it is shown in the graph that [tex]x[/tex] is only within this interval. The range of this function is [tex][-4,4][/tex], as the smallest value of [tex]y[/tex] is -4 and the largest value of [tex]y[/tex] is 4, and [tex]y[/tex] takes every possible values between them.

Answer:

C.  - ([tex]\frac{1}{3}[/tex] · [tex]\frac{1}{3}[/tex] · [tex]\frac{1}{3}[/tex] · [tex]\frac{1}{3}[/tex])

Step-by-step explanation:

-3 ^-4 = -1/3 ^4

This equal - ([tex]\frac{1}{3}[/tex] · [tex]\frac{1}{3}[/tex] · [tex]\frac{1}{3}[/tex] · [tex]\frac{1}{3}[/tex])

Answer:

d = 2

Step-by-step explanation:

14d - 22 +5d = 12d - 8

19d -22 = 12d - 8

      +22         +22

    19d = 12d + 14

  -12d   -12d

     7d = 14

    /7       /7

      d = 2

Answer:

d = 2

Step-by-step explanation:

Simplifying

14d + -22 + 5d = 12d + -8

Reorder the terms:

-22 + 14d + 5d = 12d + -8

Combine like terms: 14d + 5d = 19d

-22 + 19d = 12d + -8

Reorder the terms:

-22 + 19d = -8 + 12d

Solving

-22 + 19d = -8 + 12d

Solving for variable 'd'.

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

Add '-12d' to each side of the equation.

-22 + 19d + -12d = -8 + 12d + -12d

Combine like terms: 19d + -12d = 7d

-22 + 7d = -8 + 12d + -12d

Combine like terms: 12d + -12d = 0

-22 + 7d = -8 + 0

-22 + 7d = -8

Add '22' to each side of the equation.

-22 + 22 + 7d = -8 + 22

Combine like terms: -22 + 22 = 0

0 + 7d = -8 + 22

7d = -8 + 22

Combine like terms: -8 + 22 = 14

7d = 14

Divide each side by '7'.

d = 2

Simplifying

d = 2

x=5th test score

(88+85+100+86+x)/5=90

(359+x)/5=90

71.8+x/5=90

-71.8              -71.8

x/5=18.2

*5       *5

x=91

the fith test score has to be 91 in order for the average to be 90

Answer:

c (6)

Step-by-step explanation:

by the corresponding angles postulate, the angle above 20x-5 will be 65°.

20x - 5 + 65 = 180 they are supplementary angles (angles that add up to 180°)

20x + 60 = 180

20x = 120

x = 6

Answer:

16 1/2 gallons of water.

Step-by-step explanation:

Since 4 bottles can hold 8 gallons, and you need to know how much 10 can hold, you can multiply 4 and 8 times 2 so you get 8 and 16, and then if you choose 10 instead of 8 instead you would get the result of 10 bottles being able to hold 16 1/2 gallons of water.

I hope this helps you :D

Answer:n=2.3.5(n-2)+9=n=44.6

Answer:

yes, no, no, yes

Step-by-step explanation:

Plug in each point into both equations to see which ones fit.

For the first point, (4,1) it works for both equations.

1=-2( 4 ) + 9, 1= -8 + 9, 1=1

4( 4 )+2( 1 )=18, 16 + 2 = 18, 18 = 18

Do it for the rest of the points and plug them in and you get,

no for (5,-3) because -1 does not equal to -3

no for (6,0) because -3 does not equal to 0

(-5,19) is yes because 19=19 and 18=18

Please mark me brainliest

Answer:

No, they don't.

Step-by-step explanation:

I'm going to divide 18 by 9 and 30 by 20. If the quotients are the same, then we do have a proportion.

18 ÷ 9 = 2

30 ÷ 20 = 1.5

The quotients aren't the same. Same thing if you convert the fractions to decimals:

9 ÷ 20 = 0.45

18 ÷ 30 = 0.6

This means the two values do NOT form a proportion.

Hope this helps! Have a great day!

Answer:

No.

Step-by-step explanation:

9/20=18/30

9*30=20*18

120=360

Answer:

x = 4 and y = 10

Step-by-step explanation:

-5y + 8x = -18

5y + 2x = 58

First you will want to get rid of y from both equations, so you add both equations together.

You will get 10x = 40, then subtract 10 from both sides and you get x = 4.

Now substitute x as 4 in any of the equations to get y.

-5y + 32 = -18

-5y = -50

y= 10

Answer:

x = 4

y = 10

Answer: 1

Step-by-step explanation:

2+3 = 5

10 - 5 = 5

The x’s would be just 1 to make them equal since they don’t need to be multiplied

[tex]\frac{17}{27}[/tex]

Step-by-step explanation:

Given: Events A and B are such that [tex]P(A)=38\,,\,P(B)=27[/tex] and P(A∩B) = 17

To find: [tex]P(A|B)[/tex]

Solution:

Probability refers to the chances of occurrence of any event.

An event is described as an outcome of a random experiment.

A random experiment is an experiment for which outcomes cannot be predicted.

[tex]P(A|B)=[/tex] P(A∩B) ÷ P(B) = [tex]\frac{17}{27}[/tex]

Answer:

x^2-3x+4

Step-by-step explanation:

Answer:

x = -31

Step-by-step explanation:

2(x-5) = 3(x+7)       1. Use distributive property

2x - 10 = 3x + 21     2.  Add 10 on both sides

2x = 3x + 31            3. Subtract 3x on both sides

-x = 31                       4. Divide by -1

x = -31
