Answer:

14a + 70 + 84b

Step-by-step explanation:

Each term in the parenthesis is multiplied by 14, that is

= (14 × a) + (14 × 5) + (14 × 6b)

= 14a + 70 + 84b

Solve for w.<br> 3w = 3.84

Katen [24]

Answer:

w = 1.28.

Step-by-step explanation:

To find 'w', simply divide the answer by the coefficient.

$3.84/3=1.28$

$w=1.28$

REMEMBER: ANYTIME YOU SEE A COEFFICIENT AND A VARIABLE, YOU MUST MULTIPLY THE COEFFICIENT AND THE VARIABLE.

We can check our answer by multiplying.

$3*1.28 = 3.84$ .

Therefore, w = 1.28.

1. -28 = -3n + 5<br> what is n??<br> 2.5−n3=−4

STatiana [176]

Answer:

n=11

$n = \sqrt[3]{9}$

Step-by-step explanation:

Question 1:

The given equation is:

$- 28 = - 3n + 5$

Subtract 5 from both sides:

$- 28 - 5 = - 3n$

$- 33 = - 3n$

Divide boy sides by:

-3

$n = \frac{ - 33}{ - 3} = 11$

Question 2:

The given expresion is :

$5 - {n}^{3} = - 4$

Subtract 5 from both sides

$- {n}^{3}= - 4 - 5$

This implies that;

$- {n}^{3}= - 9$

${n}^{3}= 9$

$n = \sqrt[3]{9}$

Lisa collect rain water in a large barrel that weighs 25 pounds when there are 10 gallons of water in the barrel the total weigh

igomit [66]

We can model this situation with a linear equation. We know for our problem that the initial point is (0, 25), and the next point is (10, 108.4). To relate those points and find the slope of our linear equation, we are going to use the formula: $m= \frac{y_{2}-y_{1}}{x_{2}-x_{1} }$ . Notice that we know from our points that: $x_{1}=0$ , $y_{1}=25$ , $x_{2}=10$ , and $y_{2}=108.4$ . So, lets replace those values in our formula to find $m$ :
$m= \frac{108.4-25}{10-0}$
$m= \frac{83.4}{10}$
$m=8.34$

Now that we have the slope of our linear equation, we can use the point slope formula: $y-y_{1}=m(x-x_{1})$ to complete our linear equation:
$y-25=8.34(x-0)$
$y-25=8.34x$
$y=8.34x+25$
Or in function notation: $f(x)=8.34x+25$

We can conclude that the equation that matches this situation is $y=8.34x+25$ .
