You subtract the number (5) on the other side of the = sign from the number on the side of the = sign. and divide (-5a) by the number you subtracted before. So untimely- 5-5= 0 ÷ -5a = 0

Answer:

3,520 yds in 2 hours

Step-by-step explanation:

5,280:1 ; 1 mile an hour is 5,280 feet in an hour

10,560:2 ; 2 miles in 2 hours is 5,280+5,280 (10,560) feet in 2 hours

3 ft = 1 yd ; every 3 feet is a yard, so divide 10,560 by 3

10,560/3 = 3520 yds ; Jorge can walk 3,520 yds in 2 hours

OleMash [197]

Yes.  Changing the the word problem into a function, you get 30x=y.

30 = Fixed Length

x = width

y = area

No matter what width (x) you choose, the area (y) is going to be a multiple of 30 (the fixed length) because with two numbers being multiplied, if there is a fixed number that will always be the multiple and not the multiplier.  For example, 10 multiplied by every number 1-10 is going to be a multiple of 10.

10x1=10, 10x2=20, 10x3=30, etc

So if Tom chooses any of these widths (x) 5, 10, or 15, y (the area) will be a multiple of 30.

30(5)=150

30(10)=300

30(15)=450

So as we double 5 to get 10, our outcome is doubled 150 to 300 and so forth.  Hope this helps.

25 x (5 - 2) ➗ 5 - 12
joja [24]

Answer: 3

Step-by-step explanation:

25 x (5 - 2) ➗ 5 - 12

Applying the rule of BODMAS

- Solve task in bracket first

25 x (5 - 2) ➗ 5 - 12

= 25 x (3) ➗ 5 - 12

= 75 ➗ 5 - 12

- Solve task of division next

75 ➗ 5 - 12

= 15 - 12

= 3

Thus, the answer is 3
