Together sarah and max brought in 24 cookies to share with the class. Sarah brought in 7 cookies. Write an equation to find out how many cookies brought in.

Answers

Answer:

The answer is;

x = 24 -7 or 7 + x = 24

Sarah brought in 7 cookies. Max brought in 17 cookies. The both of them together brouhght in 24 cookies.

Step-by-step explanation:

Since the question is a little vague in understanding, I'm going to assume we are figuring out how many cookies Max brought in.

If you are asking for how many cookies Max brought in, you would need to isolate x and create an equation. For this you can either have x = 24 - 7 or

7 + x = 24.

The school owns 2 classroom sets of 30 calculators each, which students are required to have during their mathematics class. There are 2 calculators from one set and 6 calculators from the other set that are not available for use by the students because these calculators are being repaired. For which of the following class periods, if any, are there NOT enough calculators available for each student to use a school-owned calculator without having to share?

Answers

None since only 8 are being fixed and they have two sets of calculaters which is a grand total of 60 with the 8 calculators. Once the the 8 are are subtracted from the equation there would be 52 and there is less students in the classroom for each class leaving extra calculators to be used.

There's not enough information here.

Answers

Answer:

4353.5

Step-by-step explanation:

2 bedrooms and a living room, sorry I forgot to add that in, there's also 3 small windows and a large one

3 rooms

552*3 = 1656

small window = 539.50 * 3 = 1618.50

Large window - 2*539.50 = 1079

1656+1618.5+1079=4353.5

Answer:

J. $354

Step-by-step explanation:

There are three rooms (including the two bedrooms and one living room) that will have a ceiling fan in it. The price of one ceiling fan is $52.0 . $52 x 3= $156.

There are four windows, including one large one and three small ones. The price of one small curtain is $39.50. $39.50 x 3= $118.50 .

The price of one large curtain is double that of a small curtain. $39.50 x 2= $79.

Now, let's add this all up. $156 (3 ceiling fans) + $118.5 (3 small curtains) + $79 (1 large curtain) = $353.5

Round your answer to get $354.

Whats 3x9 + 10 x 36/6?

Answers

The solution to the expression 3 * 9 + 10 * 36/6 is 87

How to evaluate the expression

From the question, we have the following parameters that can be used in our computation:

3 * 9 + 10 * 36/6

Evaluate all the products in the expression

so, we have the following representation

3 * 9 + 10 * 36/6 = 27 + 360/6

Evaluate all the quotients in the expression

so, we have the following representation

3 * 9 + 10 * 36/6 = 27 + 60

Lastly, we have

3 * 9 + 10 * 36/6 = 87

Hence, the solution is 87

P = 1.48km = 1480m
P = 2l + 2w
l = 460
2l = 920
1480 - 920 = 560
560 = 2w
560 ÷ 2 = 280
280m = width or w
