What is the solution of y= 4x + 6 when y= 18?

Answers

Answer:

18 = 4(3)+6

12 + 6

Step-by-step explanation:

the answer is 18 = 4(3)+6

because y is 18

Answer:

x=3

Step-by-step explanation:

[tex]18 = 4x + 6[/tex]

subtract 6 on both sides

[tex]12 = 4x[/tex]

divide both sides by 4

If f (2) = 60 – 5.
find x for f (x) = 13

Answers

Answer:

The required value of [tex]x[/tex] is [tex]\frac{3}{5}[/tex]

Step-by-step explanation:

Given,

f (2) = 60 – 5

      = (30 X 2) - 5

∴ f (x) = [tex]30x-5[/tex]

Again,

f (x) = 13 [given]

[tex]30x-5=13\\or, 30x= 13+5\\or, 30x=18\\or, x=\frac{18}{30} \\\\or, x=\frac{3}{5} \\[/tex]

∴[tex]x=\frac{3}{5}[/tex]

Verification:

f (x) = [tex]30x-5[/tex]

∴ f ([tex]\frac{3}{5}[/tex]) = (30 X [tex]\frac{3}{5}[/tex]) - 5

         = 18 - 5

         = 13

∴ The required value of [tex]x[/tex] is [tex]\frac{3}{5}[/tex]

During the month of June, Addison kept track of the number of days she saw birds in her garden. She saw birds on 18 days of the month. What is the experimental probability that she will see birds in her garden on July 1? (There are 30 days in June) HURRYYYYY PLEASE

Answers

Answer:

3/5

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

Experimental probability is based on the result of an experiment that has been carried out multiples times

experimental probability that she will see birds in her garden on July 1 = number of days she saw a bird in June / total number of days in June

A bag contains 25 red cubes, 15 green cubes, 12 blue cubes, and 8 yellow cubes. The cube is picked at random from the bag. Find each probability as a fraction is lowest terms

Answers

Answer:

25/70=red cubes

15/70=green cubes

12/70=blue cubes

8/70=yellow cubes

Step-by-step explanation:

you have to add up all the cubes together and get 70 so you have to see the possibility of getting each cube from the bag.

sorry if you get this wrong

Answer:

Step-by-step explanation: Alright so first add up how many cubes there are in total - 25 + 15 + 12+ 8 = 60. Then, each color cube is its number out of 60. So, for example, for 25 red cubes, it would be 25/60 as a fraction and that’s the probability as a fraction for the red cubes. So:

red = 25/60

green = 15/60

blue = 12/60

yellow = 8/60

then simply the fractions.

25/60 —> 5/12

15/60 —> 1/4

12/60 —> 1/5

8/60 —> 2/15

I hope that helped!

(19x + 3)° is an exterior angle of the triangle, then

11x - 2 + 9x + 1 = 19x + 3

20x - 1 = 19x + 3 ( subtract 19x from both sides )

x - 1 = 3 ( add 1 to both sides )

Amy is baking her famous pies to sell at the Town Fall Festival. She uses 32 ¼ cups of flour for every 1 ½ batches of pie that she makes. How many cups of flour would Amy use for 7 batches of pie?

Answers

Answer:

150-1/2 (150.5) cups of flour

Step-by-step explanation:

We know there is a ratio of 32.25 / 1.5 (32-1/4 cups of flour for every 1 1/2 batches of pie that she makes). X is the unknown (as we are trying to solve for flour) so we can set up the problem as such:

32.25    =     x  

1.5                 7

Now we cross multiply to solve:

1.5(x) = 7(32.25)

1.5x = 225.75  -- Simplify then divide both sides by x (to isolate the variable)

x = 150.5

Answer: She uses 32 ¼ cups of flour for every 1 ½ batches of pie

Let’s make it into whole numbers to start…

She uses 64 ½ cups of flour for every 3 batches of pie

She uses 129 cups of flour for every 6 batches of pie

She uses 129/6 cups of flour for every 1 batch of pie

She uses 7 x 129/6 cups of flour for every 7 batches of pie

= 150 ½ cups of flour
