Answer:

x=4

Step-by-step explanation:

2x+4=12

Step 1: subtract both sides by 4

4-4=0 and 12-4=8

Now you are left with 2x=8

Step 2: divide 2 on both sides

2/2=1x and 8/2=4

Therefore, x=4

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¢

Evaluate the following:<br><br> Options are:<br> -20<br> 0<br> 20<br> The integral diverges
victus00 [196]

Answer:

The integral diverges

Step-by-step explanation:

∫₋₁¹ 10/x² dx

There is a discontinuity in the function at x = 0.  Splitting this into two integrals:

∫₋₁⁰ 10/x² dx + ∫₀¹ 10/x² dx

-10/x |₋₁⁰ + -10/x |₀¹

∞
