Answer:

9/25

Step-by-step explanation:

$\frac{3}{5x} - \frac{2}{3} = 1$

$\frac{3}{5x} = 1 + \frac{2}{3}$

by taking LCM,

$\frac{3}{5x} = \frac{3}{3} + \frac{2}{3}$

$\frac{3}{5x} = \frac{3+2}{3}$

$\frac{3}{5x} = \frac{5}{3}$

cross multiply

5x × 5 = 3 × 3

25x = 9

x = 9/25

hope this helps you!!

This table shows a proportional relationship between the number of cups of sugar and flour used for a recipe.

inna [77]

To find the answer for one cup of flour, divide the cups of sugar by the cups of flour. Here’s how it works.

Since we want the proportion for 1 cup of flour, we divide it by itself to get 1.

Thus, we need to have equal sides, so we divide the number of cups of sugar by the amount the cups of flour divided by.

So: 2.5/7.5=1/3

1 cup of flour is proportional to 1/3 cups of sugar.

Hope this helps!

Circle A was translated 3 units to the left and 4 units up to create Circle B. Which rule describes the translation that was app

kifflom [539]

Answer:

$B = (x - 3, y + 4)$

Step-by-step explanation:

Given

Represent the coordinates of circle A with (x,y)

Translation

Left = 3 units

Up = 4 units

Required

Determine the coordinates of B

When a point (x,y) is translated by h units left, the new point is: (x - h, y)

When a point (x,y) is translated by b units up, the new point is: (x, y + b)

So, when circle A is completely translated to B, the new points of B is:

$B = (x - h, y + b)$

In this case:

$h = 3\ and\ b = 4$

So:

$B = (x - 3, y + 4)$

Sarah graphed the solution to the inequality StartAbsoluteValue f + 3 EndAbsoluteValue less-than 9 on the number line.

sertanlavr [38]

Answer:

Correct option: first one.

Step-by-step explanation:

Let's analyse each option:

When f = 0, |0 + 3| < 9, which is true because 3 is less than 9.

This statement is true, and the value f = 0 in inside the solution graphed by Sarah.

When f = -12, |-12 + 3| < 9, which is true because 9 is equal to 9.

This statement is false, because the inequality uses a "less-than" symbol and not a "equal" symbol, so 9 < 9 is false

When f = 10, |10 + 3| < 9, which is true because 9 is greater than 13.

This statement is false, because 9 is not greater than 13.

When f = -14, |-14 + 3| < 9, which is true because 9 is greater than –11.

This statement is false, because the value of |-14 + 3| is 11 and not -11.

So the correct option is the first one.
