Use properties of multiplication to show why 4 x 50 = 8 x 25.

nikdorinn [45]

Given:

$4\times 50 =8\times 25$

To find:

The steps to prove the given statement by using the properties of multiplication.

Solution:

We have,

$4\times 50 =8\times 25$

Taking left hand side, we get

$LHS=4\times 50$

$LHS=4\times (2\times 25)$

$LHS=(4\times 2)\times 25$ (Associative property of multiplication)

$LHS=8\times 25$

$LHS=RHS$

Hence proved.

Thom’s restaurant bill is $45 and he leaves a 20 percent tip. What is the total cost for Thom’s meal?

Studentka2010 [4]

Answer:

$54

Step-by-step explanation:

$\frac{x}{45} = \frac{20}{100}$

To get x which is the 20% tip

1. 45×20 = 900

2. 900÷100=9

3. 9 is the tip

To get the total cost, you would have to add $9 to $45 which is $54.

What is the slope of the line that passes through the points (−8,−1) and (−6,−2)? Write your answer in simplest form.

4vir4ik [10]

Answer:

m = -1/2

Step-by-step explanation:

Recall that slope = (change in y) / (change in x).

Going from (−8,−1) to (−6,−2), x increases by 2 (because -6 - (-8) = 2), and

y decreases by 1. Thus, the slope here is

m = (change in y) / (change in x) = (-1) / 2 = -1 / 2

m = -1/2
