Alex went to the grocery store and bought 5 avocados. He paid $10 and received $4.50 in change. How much did each avocado cost i
Delvig [45]

Answer:

$1.10

Step-by-step explanation:

We have been that Alex went to the grocery store and bought 5 avocados. He paid $10 and received $4.50 in change.

First of all, we will find amount paid for 5 avocados by subtracting $4.50 from $10.

\text{Amount paid for 5 avocados}=\$10-\$4.50

\text{Amount paid for 5 avocados}=\$5.50

Now, we will divide $5.50 by 5 to find cost of each avocado.

\text{Cost of each avocado}=\frac{\$5.50}{5}

\text{Cost of each avocado}=\$1.10

Therefore, the cost of each avocado is $1.10.

The square below has an area of 22 - 10.2 + 25 square meters.
ZanzabumX [31]

Answer:

x = 1.89

Step-by-step explanation:

Solve 22 - 10.2 + 25 to get 36.8 as the square's area.

Set up the equation 36.8 = (-10x + 25)^2 to represent the relationship between one side length and the area.

Reverse the equation to solve for x! Find the square root of both sides to cancel out the exponent. This gets you: 6.07 = -10x + 25.

Subtract 25 from both sides, then divide by -10 to get x by itself.

x = 1.89
