<h3>Answer: b+5a</h3>

Explanation:

The commutative property of addition is where we can add two numbers in any order.

The general equation is x+y = y+x

A more concrete example would be something like 2+3 = 3+2 since both sides simplify to 5.

For 5a+b, it is the same as b+5a. We swap the two terms.

The measure of the angle x is 117 degrees

<h3>Line geometry.</h3>

To determine the value of x in the given diagram, we will use the alternate angles theorem

The value of x is expressed as shown;

p + q= x

If the value of p = 51, then;

51 + q. = x

Determine the value of. q

q = 108 - 42

q = 66

Determine the value of x

x = 66 + 51

x = 117 degrees

Hence the measure of the angle x is 117 degrees

Elena went to the store where you can scoop your own popcorn and buy as much as you want.she brought 10 ounces of spicy popcorn

kifflom [539]

Answer:

A. 4 ounces

Step-by-step explanation:

Given that Elana paid $2.50 for 10 ounces of popcorn, let x be the amount popcorn a dollar will buy.

Thus we have:

$2.50 = 10 ounces

$1 = x

Cross multiply

$2.50 × x = 10 ounces × $1

Divide both sides by $2.50

($2.50 × x)/$2.50 = (10 ounces × $1)/$2.50

x = (10 ounces)/2.50

x = 4 ounces

Therefore, you can buy 4 ounces of popcorn per dollar

(8.5H)Which situation represents 1 point

<h3>The cost of purchasing baby chicks at $4.50 per chick represents proportional relationship</h3>

<em><u>Solution:</u></em>

in a proportional relationship, one variable is always a constant value times the other.

y = kx

Where, k is a constant

<em><u>Option 1</u></em>

The cost of purchasing hay for $26 a bale with a delivery charge of $30

Cost = $ 26 a bale + 30

This does not forms a proportional relationship

<em><u>Option 2</u></em>

The cost of purchasing baby chicks at $4.50 per chick

Let "x" be the number of chicks

Therefore,

$cost = 4.50 \times x$

Thus, this forms a proportional relationship

<em><u>Option 3</u></em>

The cost of purchasing fencing at $29 a linear foot with an installation fee of $300

cost = $ 29 a linear foot + 300

This does not forms a proportional relationship

<em><u>Option 4</u></em>

The cost of renting a backhoe for $79 per hour with a non-refundable deposit of $300

cost = $ 79 per hour + 300

This does not forms a proportional relationship
