First, you must understand the question. what % of 60 is 15, so I would write an equation to express this.

15 = 60x

From there, solve for x, so Divide by 60 on each side. The answer is 1/4, or 25%

A recipe calls for 1 1/4 cups of flour, 3/4 cup of white sugar, and 1/3 cup of brown sugar. The recipe makes 4 servings. How man
sleet_krkn [62]

Answer:

Cups of flour 5/16

Cups of sugar 3/16

5/8 more cups of flour we need for 6 servings

Step-by-step explanation:

Cups of flour

We need to divide the total of flour (1 1/4) in the total of servings (4)

=(1 1/4)/4

=5/16 cups of flour for servings

Cups of sugar

We need to divide the total of sugar (3/4) in the total of servings (4)

=(3/4)/4

=3/16 cups of sugar for servings

If the recipe is for 6 servings

You need to add more flour and sugar to complete 6 servings

1 1/4 flour=4 servings

x flour=6 servings

(1 1/4 flour*6 serving)/4 servings=x flour

x flour= 15/8 cups of flour

The difference

First 1 1/4 cups

Then 1 7/8

More cups of flour=5/8

Write the multiplicative inverse of <br>a) -13/19​
irga5000 [103]

Answer:

-  \frac{19}{13}

Step-by-step explanation:

the \: multiplicative \: inverse \: of \:  \\  -  \frac{13}{19}  =  -  \frac{19}{13}

Product of a number and its multiplicative inverse should be equal to 1.

So,

\bigg ( -  \frac{13}{19} \bigg)  \bigg ( -  \frac{19}{13} \bigg)

= \frac{13}{19}\times  \frac{19}{13}

=1

How do you complete solving two step equations
Gekata [30.6K]

Answer:

Here's a two step equation for example: 4.8y - 6.9 = 3.18

Step-by-step explanation:

How I solve it is using: Sadmep.

wth is that?

Well, it's pemdas backwards. You use this version for solving 2 step equations. But pemdas, not a two step equation.

But, how to solve it: Sadmep..S stands for subtraction...do I see it? Yes! So we are going to do inverse operations..what's the inverse of subtraction..Addition! So you are going to put an addition sign right under the subtraction, and put 6.9..now what you do to one side, you have to do to the other. So add 6.9 to 3.18. Now once you did that, you have to add, but you can't add the 6.9 and the 6.9, you have to cross it out, but you HAVE to hadd 3.18 and 6.9..so do that. So for right now your answer should be: 4.8y = 10.08...let's finish solving! Now since there are two unlike terms, when it comes down to literally this, you have to divide each side by the number with the variable. So: 4.8y divided by 4.8...and 10.08 divided by 4.8.. now remember what I said..4.8y divided by 4.8 are alike so you have to cross it out. But you HAVE to divide 10.08 by 4.8. And once you do that..:::: y = 2.1 ....see? easy and simple!
