First solve
3(5 + 6).
5+6=11
Now 3*11=33
So now which of the answers also=33?
8+9=17 so no
8+6=14 so no aswell
15+18=33 therefore this is correct. so your answer is c.
15+6=21 so no

Can i get some help :
Charra [1.4K]

Answer:

b = \frac{7}{12}

Step-by-step explanation:

b + \frac{2}{3} = 1 \frac{1}{4} ← change to an improper fraction

b + \frac{2}{3} = \frac{5}{4}

Multiply through by 12 ( the LCM of 3 and 4 ) to clear the fractions

12b + 8 = 15 ( subtract 8 from both sides )

12b = 7 ( divide both sides by 12 )

b = \frac{7}{12}

A bag contains only pink , black and yellow marbles the ratio is 8:7 the ratio of black to yellow is 1:5
igor_vitrenko [27]

The percent of black is 14% if the bag contains only pink, black and yellow marbles the ratio is 8:7 the ratio of black to yellow is 1:5

<h3>What is the ratio?</h3>

It is defined as the comparison between two quantities that how many times the one number acquires the other number. The ratio can be presented in the fraction form or the sign : between the numbers.

We have:

Pink to black = 8:7

Black to yellow = 1:5

Let's suppose the pink is 8x

Black = 7x

Yellow = 7(5x) = 35x

Percent of black = 7x(100)/(8x+7x+35x)

Percent of black = 14%

Thus, the percent of black is 14% if the bag contains only pink, black and yellow marbles the ratio is 8:7 the ratio of black to yellow is 1:5

So sorry for asking for so much help but I seriously don't understand what to do for this assignment

Answer:

I'll probably come back and do this later.

Step-by-step explanation:

<u>How to Round:</u>

If the number following the number you're going to round up is 5 or above, (5, 6, 7, 8, or 9), then round up. (E.X. 2<u>9</u> rounded up is 30. Since 9 is above 5, you will round up.

On the other hand, if the number following the number you're going to round is 4 or below, (4, 3, 2, or 1), you don't round up, instead you keep it the same, and if they're are decimals, you turn the following numbers to 0s. (E.X. 32.4536 rounded to the nearest hundredth (32.45<u>3</u>6) is 32.45. Since 3 is less than 4, you're not going to round up. The number in the hundredth's place stays the same (5), and the following rest turn to 0s. Leaving you with 32.45

Let me know if this helped. :)
