Step-by-step explanation:

Using the best fit equation y = 1.5x - 1

with x = 16 ( number of years since 2000 ), then

y = (1.5 × 16) - 1 = 24 - 1 = 23

AfilCa [17]

22 quarters= $5.50
10 dimes= $1.00

$5.50 + $1.00 = $6.50
I just did trial and error. I started with 20 quarters and made changes until it worked.

Substitute each given value of the variable to find which, if any, is a solution of inequality.

OlgaM077 [116]

Given:

The inequalities are:

a) $w$

b) $t>-25, t=-24, -25, -25.1, -27$

To find:

The solution of inequalities by substituting the given values.

Solution:

a) We have,

$w$

After substituting the given values one by one, we get

$-4.3$ False statement.

$-5.3$ False statement.

$-8.3$ True statement.

$-9$ True statement.

Therefore the solutions of $w$ are $w=-8.3, -9$ .

We have,

$t>-25, t=-24, -25, -25.1, -27$

After substituting the given values one by one, we get

$-24>-25$ True statement.

$-25>-25$ False statement.

$-25.1>-25$ False statement.

$-27>-25$ False statement.

Therefore, the solution of $t>-25$ is $t=-24$ .

X(5)+2=244<br>help pls<br>(^_^)

arsen [322]

Simplify both sides of the equation

5x+2=244

Subtract 2 from both sides

5x+2−2=244−2
5x=242

Divide both sides by 5

$\frac{5x}{5} = \frac{242}{5}$

Answer

$\: x = \dfrac{242}{5}$

$\: x = 48.4$
