we simply divide the 3/4 by the 8 students.

$\bf \cfrac{3}{4}\div 8\implies \cfrac{3}{4}\div \cfrac{8}{1}\implies \cfrac{3}{4}\cdot \cfrac{1}{8}\implies \cfrac{3}{32}$

Each student gets 1/8 of the cake.

we multiply 1/8 and 3/4. To do that we multiply the numerators together and the denominators together. This gives (1*3)/(8*4) =3/32 of the cake

6(m + 2 + 7m)

Inga [223]

Part A: 6 ( 8m + 2) and 48m + 12

Part B: 48m - 48m = 12 - 12

Part C: 6 (10) = 6(10)

<h3>How to determine the expressions</h3>

1. The two expressions could be gotten thus;

6(m + 2 + 7m)

Collect like terms in the bracket

6 ( 8m + 2) ⇒ first expression

6(m + 2 + 7m)

Expand the bracket

6m + 12 + 42m

Collect like terms

6m + 42m + 12

48m + 12 ⇒ second expression

Part B:

6(m + 2 + 7m) = 48m + 2

Expand the bracket

6m + 12 + 42m = 48m + 2

Collect like terms

48m - 48m = 12 - 12

0 = 0

Part C:

Let the expression from A be 6 ( 8m + 2)

6(m + 2 + 7m) = 6 ( 8m + 2)

Let the number be m = 1

Substitute the values

6(1 + 2 + 7(1) ) = 6 (8(1) + 2)

6 ( 1 + 2 + 7) = 6 (10)

6 (10) = 6(10)

Paul's car holds at most 17 gallons of gas. Now it has 9 gallons. Explain how to find the amount of gas he needs in liters. Use

yulyashka [42]

Answer:

30.08 liters of gas.

Step-by-step explanation:

Given:

Paul's car holds at most 17 gallons of gas.

Now it has 9 gallons.

Question asked:

Explain how to find the amount of gas he needs in liters.

Solution:

Capacity of Paul's car = 17 gallons of gas.

Now it has = 9 gallons of gas.

He need more = 17 - 9 = 8 gallons of gas.

Now, we have to convert it into liters:-

As we know:

Given:

1 gallon = 4 quarts ( Unitary method )

8 gallons = $4\times8=32\ quarts$

Now, we will convert it into liters:- ( Unitary method )

1 quart = 0.94 liters

32 quart = $0.94\times32=30.08\ liters$

Thus, he needs 30.08 liters of gas.

What values are needed to make each expression a perfect square trinomial?

serg [7]

Answer:

1) 1 2)100 3)6.25.

Step-by-step explanation:

Any trinomial is of the form ax^2+bx+c .

To make the expression a perfect square we take half of b term then square it Add $(\frac{b}{2})^2$ This is what we add to make the expression a perfect square.
