The difference between a number divided by 3 and 4 is 20

Rzqust [24]

Set the number to x.

$\frac{x}{3}-\frac{x}{4}=20$
$\frac{4x}{12}-\frac{3x}{12}=20$
$\frac{x}{12}=20$
$x=240$

Thus, the number is 240.

Help please!! Solve for y.

Nimfa-mama [501]

Answer:

y = 3 $\sqrt{7}$

Step-by-step explanation:

The 2 right triangles inside the right triangle are similar, then ratios of corresponding sides are equal, that is

$\frac{y}{9}$ = $\frac{7}{y}$ ( cross- multiply )

y² = 63 ( take the square root of both sides )

y = $\sqrt{63}$ = 3 $\sqrt{7}$

The slope of the line that passes through the points (-10,y) and (5, 2) is 2/5. What is the value of y?

Murrr4er [49]

Answer:

C, -4

Step-by-step explanation:

slope=change in y/change in x

$\frac{2 - y}{5 - ( - 10)} = \frac{2}{5}$

$\frac{2 - y}{5 + 10} = \frac{2}{5}$

multiply both sides by 2/5

$2 - y = \frac{2}{5} (5 + 10)$

simplify the right side. 2/5 × 5 = 2 and 2/5 × 10 = 4

$2 - y = 2 + 4$

$2 - y = 6$

bring y to the other side by adding y on both sides

$2 = 6 + y$

subtract 6 on both sides

$2 - 6 = y$

so y is -4

Explain and show your work, please.

It is given that aiden has purchased a 2 lb package, a 3 lb package, and a 4 lb package
The first step is to add these packages together
2+3+4 is 9
each turkey burger needs 1/3 lb of turkey, which also means that every pound of turkey aiden has can make 3 turkey burgers

Aiden has 9 pounds of turkey, so he can make 27 turkey burgers (3*9)

Hope this helped! If you still need help I can answer in comments
