When multiplying by a number that is 1 with 0's on the end, you move the decimal to the right by how many zeros there are.

Because 10,000 has 5 0's, we move the decimal 5 places to the right.

8.88 => 88800

Which is the unknown quantity?<br> 8 2/3 yards/ $148.50 = 2 1/3 yards/ ?

xeze [42]

Answer: C. $39.98

Step-by-step explanation:

We have the following equation with mixed fractions:

$\frac{8\frac{2}{3}yards}{\$148.50}=\frac{2\frac{1}{3}yards}{?}$ (1)

A mixed fraction is the combination of an integer and a fraction, and to convert it into an improper fraction and be able to solve the equation more easily, we must do the following:

Mixed fraction: $a\frac{b}{c}$

Converting Mixed fraction to improper fraction: $\frac{(a)(c)+b}{c}$

So, for both mixed fractions we have:

$8\frac{2}{3}=\frac{26}{3}$

$2\frac{1}{3}=\frac{7}{3}$

Having this clear, let's solve the equation:

$\frac{26/3 yards}{\$148.50}=\frac{7/3 yards}{?}$ (2)

$?=\frac{7/3 yards}{26/3 yards}(\$148.50)$ (3)

Finally:

$?=\$39.98$

2x+y=21;y=-2x+21<br>please hurry I need this straight away

Nastasia [14]

Step-by-step explanation:

2x + y = 21

Solving

2x + y = 21

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1y' to each side of the equation.

2x + y + -1y = 21 + -1y

Combine like terms: y + -1y = 0

2x + 0 = 21 + -1y

2x = 21 + -1y

Divide each side by '2'.

x = 10.5 + -0.5y

Simplifying

x = 10.5 + -0.5y
