Trina uses 1/2 of sugar and 3/4 cup of flour in a recipe. How many cups of sugar would she need if she uses 3 cups of flour?

Answers

Answer:

2\ cups\ of\ sugar

Step-by-step explanation:

we know that

Trina uses 1/2 cup of sugar and 3/4 cup of flour in a recipe

so

by proportion

Find how many cups of sugar would she need if she uses 3 cups of flour

((1/2))/((3/4))(cups\ of\ sugar)/(cups\ of\ flour)=(x)/(3)(cups\ of\ sugar)/(cups\ of\ flour)\n \n x=3*(1/2)/(3/4)\n \nx=2\ cups\ of\ sugar
2 cups. You have 4 servings of flour so you need 4 servings of sugar.

The difference of two numbers is 18. The sum of the two numbers is 62. Let x be the greater number,and let y be the lesser number

Answers

Answer:

  • x = 40
  • y = 22

Step-by-step explanation:

We know that:

  • x - y = 18
  • x + y = 62

Work:

  • x - y = 18

       x + y = 62

  • => (x + x) + (y - y) = (18 + 62)
  • => 2x + 0 = 80
  • => 2x = 80
  • => x = 40

To find y, let's use any equation in the "we know that" section.

  • => 40 - y = 18
  • => 40 - 18 = y
  • => 22 = y

Now, let's check our work by using the second equation.

Check:

  • x + y = 62
  • => 40 + 22 = 62
  • => 62 = 62 (Proved correct)

Hoped this helped.

In an inverse variation, what happens to the values of the two variables?a.
they are both constant
c.
as one value increases, the other increases
b.
they both decrease
d.
as one value increases, the other decreases

Answers

d.
as one value increases, the other decreases
This is because when both values are multiplied, you get a constant so if one is increased the other needs to be reduced so their product can meet up with the constant
