Answer:

X is equal to -10

Step-by-step explanation:

#1. Multiply 6 to (1+x). Doing this makes this equation: 6+6x+x=-14

#2. Then add 6x and x to get: 7x+6=-14

#3. Then move 6 to other side of equation, while at the same time, changing it's absolute value: 7x=-14-6

#4. now you have: 7x=-20, now just divide 7 by -20 WooHoo! You finished it! you have: -2.85714285714 or 2 and 43/50.

Andrea bought 1 2/5 pounds of avocados at $4.20 per pound and 2 1/

guapka [62]

Answer:

$14.43¢

Step-by-step explanation:

We are given; $1\frac{2}{5}$ pounds, 1 pound = $4.20 and $2\frac{1}{4}$ pounds,1 pound = $3.80 that Andrea bought.

Now we need to find her total cost. To do that, we must first find the cost of the avocados. To do so, let us set up a graph. But before that is done, convert $1\frac{2}{5}$ to a decimal. It is 1.4. Now we can set up a graph.

<u>Avocados</u>

$\frac{4.2}{1}=\frac{x}{1.4}$

Switch sides

$\frac{x}{1.4}=\frac{4.2}{1}$

Apply rule: $\frac{a}{1}=a$

$\frac{x}{1.4}=4.2$

Multiply both sides by 1.4

$\frac{1.4x}{1.4}=4.2\cdot \:1.4$

Simplify

$x=5.88$

So, her cost for avocados is $5.88¢

Now we must first find the cost of the avocados. To do so, let us set up a graph. But before that is done, convert $2\frac{1}{4}$ to a decimal. It is 2.25. Now we can set up a graph.

<u>Asparagus</u>

$\frac{3.8}{1}=\frac{x}{2.25}$

Switch sides

$\frac{x}{2.25}=\frac{3.8}{1}$

Apply rule : $\frac{a}{1}=a$

$\frac{x}{2.25}=3.8$

Multiply both sides by 2.25

$\frac{2.25x}{2.25}=3.8\cdot \:2.25$

Simplify

$x=8.55$

So, her cost for asparagus is $8.55¢

<u>Total cost</u>

Now that we have found out how much both of the fruits Andrea bought costs, we need to sum it up (meaning add it) to find the total cost:

$5.88¢ + 8.55¢ =

5.88 + 8.55 = 14.43

Therefore, Andrea's total cost of the fruits is $14.43¢

Writing an Equation from a Table

Anastasy [175]

The equation of the line will be y = 4x. Then the correct option is A.

<h3>What is the equation of line?</h3>

The equation of line is given as

y = mx + c

Where m is the slope and c is the y-intercept.

Writing an Equation from a Table

A 2-column table with 6 rows. Column 1 is labeled x with entries 8, 12, 16, 20, 24, 28. Column 2 is labeled y with entries 2, 3, 4, 5, 6, 7.

Then at (2, 8) and (3, 12), we have

y – 8 = [(12 – 8) / (3 – 2)] (x – 2)

y – 8 = 4x – 8

y = 4x

Then the correct option is A.

20 how much metal is needed to smelt a cubical metal box with outer side 12 inches long if the thickness of its walls should be

guajiro [1.7K]

The volume of the metal box if the box was completely solid (V1), is:

V1=(12 inches)³
V1=1728 inches³

As there are 3 inches of metal on both sides, the widht if the metal box was not completely solid, is:

W=12 inches-(3 inchesx2)
W=6 inches

Then, the volumen of the no solid metal box is:

V2=(6 inches)³
V2= 216 inches³

Therefore, the volume of metal needed to smelt the cubical metal box, is:

V3=V1-V2
V3=1728 inches³-216 inches³
V3=1512 inches³

For brainily please help

steposvetlana [31]

Answer: b = 69

The slashes mean the opposite angles are the same. This is and isosceles triangle, which mean two sides are the same and one is not.

A triangle = 180

We know one angle is 42 and the other two angles are the same.

Subtract 42 from 180

180 - 42 = 138

Now the 138 is going to two sides but we know they are equal so we can divide 138 by 2

138 divided by 2 = 69

So b = 69
