f(x) = 4x +5 when f(x) = 17

Answers

Answer:

[tex]\huge\boxed{\sf x = 3 }[/tex]

Step-by-step explanation:

Given that

f(x) = 4x + 5

Put f(x) = 17

17 = 4x + 5

Subtract 5 to both sides

17 - 5 = 4x

12 = 4x

Divide 4 to both sides

12 / 4 = x

3 = x

x = 3

Answers

Answer:

x = 11 units

Step-by-step explanation:

Area of triangle = (base + base 2) * h *1/2

so (7 + x )* 7 * 1/2 = 63

63 x 2 = 126

126 / 7 = 18

18-7 = x

x = 11

Check

(7+11)* 7 * 1/2

18* 7 = 126

126 x 0.5 = 63

CORRECT!

A rectangle has a width that is 5 feet less than the length. The area of the rectangle is
126 square feet. Find the width of the rectangle. (Do not type units in the answer)

Answers

Answer:

Step-by-step explanation:

divide 63 in the ratio 2:5​

Answers

Answer:

18 : 45

Step-by-step explanation:

add the parts of the ratio, 2 + 5 = 7 parts

Divide the quantity by 7 to find the value of one part of the ratio

63 ÷ 7 = 9 ← value of 1 part of the ratio , then

2 parts = 2 × 9 = 18

5 parts = 5 × 9 = 45

Then 63 = 18 : 45 in the ratio 2 : 5

There are 320 students in a school. The ratio of the number of boys to the number of girls is 3:2. When some new boys and girls are admitted, the number of boys increases by 8 and the ratio of number of boys and girls changes to 4:3. Find how many new girls are admitted.​

Answers

320/5=64
64 x 3 = 192 (number of boys in the beginning)
64 x 2 = 128 (number of girls in the beginning)
192 + 8 = 200 (boys now)
200/4=50
50 x 3 = 150
150 - 128 = 22 (amount of girls added)
Number of girls added: 22

Answer:

Stain required to stain the ramp = 2 quarts

Step-by-step explanation:

Area of the wheelchair ramp to be stained = Surface area of the ramp - Area of the rectangular base

Surface area of the ramp = 2(area of the triangular base) + (perimeter of the base)(height)

Area of the triangular base = [tex]\frac{1}{2}(\text{Base})(\text{Height of the triangle})[/tex]

                                             = [tex]\frac{1}{2}(25)(\frac{25}{12})[/tex]

                                             = [tex]\frac{625}{24}[/tex] in²

Perimeter of the triangular base = [tex]25\frac{1}{12}+25+\frac{25}{12}[/tex]

                                                      = 25 + [tex]\frac{1}{12}[/tex] + 25 + [tex]\frac{25}{12}[/tex]

                                                      = 50 + [tex]\frac{26}{12}[/tex]

                                                      = 50 + [tex]2+\frac{2}{12}[/tex]

                                                      = [tex]52\frac{1}{6}[/tex] ft

Surface area of the ramp = [tex]\frac{625}{12}[/tex] + [tex](52\frac{2}{12})\times 5[/tex] - 25×5

                                          = [tex]\frac{625}{12}+\frac{3130}{12}-125[/tex]

                                          = [tex]\frac{3755}{12}-125[/tex]

                                          = 187.92 square feet

Since, 100 square feet area is covered by the stain = 1 quart

Therefore, 187.92 square feet will be covered by the stain = [tex]\frac{187.92}{100}[/tex]

= 1.8792

≈ 2 quarts

Jacie is serving steak and chicken she wants to have at least 20 pounds of meat. Steak is $8 per pound and chicken is $4 per pound . Jacie wants to spend at most 120 dollarss on meat

Answers

Answer:

She can get 10 pounds of steak and 10 pounds of chicken.

Step-by-step explanation:

As Jacie wants to have at least 20 pounds of meat, you can write the following  equation:

x+y=20, where

x refers to the pounds of steak

y refers to the pounds of chicken

Also, since the statement indicate that the steak is $8 per pound and chicken is $4 per pound and Jacie wants to spend at most 120 dollars on meat, you can write the following equation:

8x+4y=120

So, you have the following equations:

x+y=20 (1)

8x+4y=120 (2)

Now, you can solve for x in (1):

x=20-y (3)

Then, you can replace (3) in (2) and solve for y:

8(20-y)+4y=120

160-8y+4y=120

160-120=8y-4y

40=4y

y=40/4

y=10

Finally, you can relace the value of y in (3) to find x:

x=20-y

x=20-10

x=10

According to this, the answer is that she can get 10 pounds of steak and 10 pounds of chicken.

What is the range of a function and how do you solve for it?

Answers

More generally, if we want to find the full range of y=x2+1, we can solve for x (taking the inverse of the function) to get x=√y−1. Then, the range of f(x) is simply the domain of √y−1, because these are all the values where there is some x-value with f(x)=y.

A school board voted whether to adopt a new math text book.Those that voted yes outvoted those that voted no by a ratio of 5:1 if 18 total school board members voted in the meeting how many voted yes for new math books?

Answers

Answer:

Members that voted yes = 15 Members

Step-by-step explanation:

Members that voted yes : members that voted no = 5 : 1

Total ratio = 5 + 1 = 6

total school board members that voted = 18

how many voted yes for new math books?

Members that voted yes = 5/6 × 18

= 0.8333333333333 × 18

= 15 members

Members that voted yes = 15 Members

members that voted no = 1/6 × 18

= 0.1666666666666 × 18

= 3

Answers

To find the difference between two numbers you would subtract them.

You are told the first number is 7 and you want to find the different of 7 and a number, which is represented by the letter n.

To find the difference you would subtract n from 7, which would be written as 7 - n

The correct answer would be 2. 7 - n ( 7 minus n)

Answer: 7 - n (Look at the explanation to understand it clearly)

Normally you'll subtract this equation, but since there isn't a number but is a variable, you would have to rewrite it.

In this problem, we would represent n as the variable and 7 as the number. Rewrite it like this:

7 - n

Or you could say it like this:

A number decreased by 7.

"A number" would represent the variable.

Hence, your answer is 7 - n.
