Answer:

Step-by-step explanation:

So the diagram shows the weight of each puppy in pounds.

Each dot is a puppy.

The first dot is at 1/4 pounds meaning you have one dog that weights that much.

At the other end, you have 3 dots at 3/4 pounds meaning you have one dog that weights that much.

The heaviest puppy is 3/4 and the lightest is 1/4.

So dividing 3/4 / 1/4 = 3/4 * 4 = 3.

So 3 times as great

Please hurry. Solve the equation

Lelu [443]

The value of x is $5\sqrt[3]{25}$ .

Solution:

Given expression is $-7=8-3 \sqrt[5]{x^{3}}$ .

Switch both sides.

$8-3 \sqrt[5]{x^{3}}=-7$

Subtract 8 from both side of the equation.

$8-3 \sqrt[5]{x^{3}}-8=-7-8$

$-3 \sqrt[5]{x^{3}}=-15$

Divide by –3 on both side of the equation.

$$\frac{-3 \sqrt[5]{x^{3}}}{-3} =\frac{-15}{-3}$

$\sqrt[5]{x^{3}}=-5$

To cancel the cube root, raise the power 5 on both sides.

$(\sqrt[5]{x^{3}})^5=(-5)^5$

$x^3=3125$

To find the value of x, take square root on both sides.

$\sqrt[3]{x^3}=\sqrt[3]{25}$

$x=5\sqrt[3]{25}$

Hence the value of x is $5\sqrt[3]{25}$ .

A line segment has endpoints (-2,-3) and (4,4). Find the length of the segment and find the midpoint.

\\\\\\
d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}

Answer:

B, E, F

Step-by-step explanation:

A. 4x and 5 + x

B. 2b + b and 3b

C. 3x and 3 + x

D. a ÷ 1/3 and 1/3 a

E. a ÷ 1/3 and a × 3

F. 1a and a

_____

<em>Comment on the above</em>

ax is multiplication of x by 'a'. a+x is addition. They are different operations.

x/(1/3) is not the same as x(1/3). Multiplication and division are different operations.
