18x + 9y use the distributive property to write an equivalent expression

Answers

Hey there!
It looks like you have another factoring question!
Using our definition of the distributive property:
a(b+c) = ab+ac
We need to factor our or greatest common multiple, which here is 9.
9 times 2x = 18x and 9 times y = 9y
We have:
9(2x + y)
Once again, using the distributive property, multiply it out and you'll get 18x and 9y.
Hope this helps!

PLEASE HURRY WILL MARK AS BRAINLIESTV- A committee at the neighborhood recreation center is planning their annual spring social. They have a budget of $295 to plan the event. They have already spent $225 on
various supplies. They still plan to purchase balloons to decorate the room at a cost of $0.65 per balloon. Which of the following inequalities represents the total number of
balloons, b, they can purchase and not spend over their budgeted amount?

Answers

Answer:

There are two inequalities that represent the total number of

balloons, b, they can purchase and not spend over their budgeted amount:

0.65b ≤ 70

0.65b + 225 ≤ 295

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Budget to plan the event = $ 295

Expenses on supplies so far = $ 225

Cost of each balloon = $ 0.65

2. Which of the following inequalities represents the total number of

balloons, b, they can purchase and not spend over their budgeted amount?

1. Let's find how much of the budget is still available:

Budget available = Budget to plan the event - Expenses on supplies so far

Budget available = 295 - 225

Budget available = $ 70

2. Let's find the inequality that represents the total number of

balloons, b, they can purchase and not spend over their budgeted amount.

Number of balloons ≤ Budget available/Cost of each balloon

Replacing with the values we know, we have:

b ≤ 70/0.65

0.65b ≤ 70

or we can write it also including the total budget this way:

Number of balloons  ≤ Budget to plan the event - Expenses on supplies so far /Cost of each balloon

Replacing with the values we know, we have:

b ≤ (295 - 225)/0.65

0.65b ≤ 295 - 225

0.65b + 225 ≤ 295

Rocky family recipe for macaroni and cheese makes 4 servings of 310 calories each. Rocky decided to make 1.5time the recipe. How many calories,are in rocky batch of Mac and cheese

Answers

There are 4 servings with 310 calories in each serving
310×4=1,240 calories altogether
Since any number times 1 is the number, you just focus on the .5
.5 is also (1)/(2) which is half of a number
1,240×.5=620
1,240+620=1,860
There are 1,860 calories in the batch

This is the more deconstructed, longer way in doing it
So an easier way is simply multiply 1,240×1.5=1,860
