50 magazines

because ratio is division and 225/5 is 25 and you multiply the 2 by 25 and you get 50

There are 64 magazines in the library.

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.

We have to given that;

The ratio of books to magazines in the children's section at the library is 5: 2.

Let number of books = 5x

And, Number of magazines = 2x

Here, There are 225 books in the library.

Hence, We can formulate;

⇒ 5x + 2x = 225

⇒ 7x = 225

⇒ x = 32

Hence, Number of magazines = 2x

                                               = 2 × 32

                                               = 64

Answer:

y=5x+11

Step-by-step explanation:

You can solve this with the point-slope formula: y-y1=m(x-x1). The line is parallel; both slopes are equivalent.

First we have to rewrite the original equation, which is rewritten into y=5x+2 by subtracting -5x on both sides.

Next, plug in the coordinates we have into the point-slope formula (-2, 1), along with the slope from the original equation (5). To check, we can plug the coordinates back into the equation.

y-(1)=5(x+2)

y-1=5x+10

y=5x+11

Check:

(1)=5(-2)+11

1=-10+11

1=1

Step-by-step explanation:

Answer:

a. 21 = u1 + 6·d

b. 29 = u1 + 10·d

c. d = 2, u1 = 9

Step-by-step explanation:

a. The given parameters are;

The amount of therapeutic drug Kiri receives on her first at the hospital = u1 milligrams

The amount of drug increase received by Kiri each day = d

The amount of drug Kiri received on the seventh day = 21 mg

The amount of drug she received on the eleventh day = 29 mg

Therefore, we have an arithmetic progression with the formula for the nth term given as follows;

aₙ = a₁ + (n - 1)·d

Where;

a₁ = u1

n = The number of terms

Therefore, for the 7th day, the amount of drugs she receives, which is 21 milligrams, is given as follows;

a₇ = u1 + (7 - 1)·d = u1 + 6·d = 21

The equation for the amount of drugs she receives in terms of u1 and d on the seventh day is given as follows;

21 = u1 + 6·d

b. For the eleventh day, the amount of drugs she receives, which is 29 milligrams, is given as follows;

a₁₁ = u1 + (11 - 1)·d = u1 + 10·d = 29

Therefore, the equation for the amount of drugs she receives in terms of u1 and d on the  eleventh day is given as follows;

29 = u1 + 10·d

c. Therefore, we have two equations which are given as follows;

21 = u1 + 6·d................(1)

29 = u1 + 10·d..............(2)

Subtracting equation (1) from equation (2) gives;

29 - 21 = (u1 + 10·d) - (u1 + 6·d)

8 = 4·d

d = 8/4 = 2

d = 2

From equation (1), we have;

21 = u1 + 6·d = u1 + 6×2 = u1 + 12

21 = u1 + 12

21 - 12 = u1

∴ u1 = 9

d = 2, u1 = 9.

x=2.666 repeated

Step-by-step explanation: this is correct, pls mark brainliest.  take -4 and add it to the other side(+4). 6x=3x+8.  subtract 3x from 6x. 3x=8. take 3x and devide it on bolth sides. x=2.666 repeated

Answer:

x = 3/8

Step-by-step explanation:

6x -4 = 3x + 4

Step 1 - Add 4 on both sides

6x -4 = 3x + 4

+ 4 + 4

6x = 3x + 8

Step 2 - Subtract 3x on both sides

6x = 3x + 8

-3x -3x

3x = 8

Step 3 - Divide 3 on both sides

3x = 8

Answer:

This ladder will be long enough because the top of the roof is 15ft 9in and that's < 25

explanation:

470 = 29x+35

(x is number of birthday cakes)

subtract 35 from both sides,

435 = 29x

divide both sides by 29 to get x by itself,

15 = x

15 birthday cakes were made!

Answer:

35+29x=470 x=15 cakes

Step-by-step explanation:

3 35 represents rate for the oven and then 29 dollars per cake is the 29. 470 is the total amount of money you spent you just have to solve the equation from then to get x equals 15
