NEED HELP WITH 3 4 AND 5

Mathematics

56 x 33 = 1,848. First you do 3x6 which = 18. So you then put the one on top of the five and put the 8 under the equation because you will have to add it later. Then you do 3x5+1= 16 so your top row of numbers under the line that means equal is 168. Then you will do the same thing except you will add a zero on the second line before the other numbers. Finally, you add the two rows together and you get 1,848.

The tank at a gas station contained 400 gallons of gas. A tanker truck that contained 8,100 gallons of gas filled the station's
spin [16.1K]

Answer:

1300

Step-by-step explanation:

Let the amount put in the station's tank = x

4(400 + x) = 8100 - x                           Remove the brackets

1600 + 4x = 8100 - x                            Subtract 1600 from both sides

1600 - 1600 + 4x = 8100 - 1600 - x     Do the subtraction

4x = 6500 - x                                        Add x to both sides

4x + x = 6500 - x + x        

5x = 6500                                            Divide by 5

5x/5 = 6500/5                                      

x = 1300

1300 gallons were added to the station's tank.

A candy company puts 7 gumdrops in each bag. How many gumdrops will the company need to fill 9 bags?​
stiv31 [10]

Answer:

63

Step-by-step explanation:

In these 9 bags, each must have 7 gumdrops. So, we can add 7 nine times to itself. 7 + 7 + 7 + 7 + ... = 63

OR HERE'S A FASTER WAY *WINK WINK*

Instead of doing repeated addition, we can <u>multiply</u> 7 and 9 together.

<u>Why multiply?</u>

We're going to multiply 7 x 9 so that it means seven gumdrops for <em>each</em> of nine bags.

7 x 9 = 63.
