6(-2.3x-5)+(4x+11)=

what is the answer

Answers

Answer 1
Answer: 6(-2.3x - 5) + (4x + 11)
-13.8x - 30 + 4x + 11
-13.8x + 4x - 30 + 11
-55.2x - 19

Answer: -55.2x - 19

First you distribute the 6 inside the parenthesis then add the like terms. Since you can't simplify -55.2x - 19 further you leave it as that. Hope that helps :)
Answer 2
Answer: I got 113 because I used a math app where you insert the equation and it tells you the answer so it might be wrong because it doesn't know what the variable x is (idk if that is a variable at all) sorry

The day after a national holiday, decorations were marked down 40%. Before the holiday, a patriotic banner cost $5.75. How much did the banner cost after the holiday? a. $1.15
b. $2.30
c. $3.45
d. $8.05

SHOW YOUR WORK PLEASE!!!

Answers

Answer:

The price after holiday is c. $3,45

Step-by-step explanation:

Patriotic banner cost $5,75

Mark down  (discount) is 40%

So,  the discount is $5.75 x 0,40= $2,3

The new price is the price before holiday P -

discount D

P¹= P-D

P¹=5,75-2,3

P¹= 3,45          

40% down means 60% of the original price is remaining
5.75 * .6 = $3.45
C. the banner cost $3.45

You mix 2/5 cup of red paint for every 1/4 cup of blue paint to make 1 5/8 gallons of purple paint. How much red paint and blue paint do you use

Answers

Answer=16 cups of red and 10 cups of blue

2/5=8/20=32/80
1/4=5/20=20/80
1 5/8gallons=26cups

32/80+20/80=52/80

26=x(52/80)
divide both sides by (52/80)
40=x
 In short, you multiply the mixture by 40 , so...

40*2/5=16cups of red
40*1/4=10cups of blue

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
