Answer:
it would be 60
Step-by-step explanation
<em>4*5= 20 </em>
<em>8*5=40</em>
<em>12*5=</em><u> 60</u>
<u></u>
We multiply by 5 because if we divide 20/4=5, 40/8=5, 60/12=5.
Answer:
- The rate of planes: 926 km/h and 860 km/h
=========================
<h3>Given</h3>
- Two planes travel in opposite directions,
- One plane travels 66 km/h faster than the other,
- The distance between the two planes after 6 hours is 10716 km.
<h3>To find</h3>
- The rate of of each plane
<h3>Solution</h3>
The distance traveled by two planes in an hour is:
Let the rate of one plane be x, then the other plane's rate is x - 66.
The sum of two rates is the distance traveled in one hour:
- x + x - 66 = 1786
- 2x - 66 = 1786
- 2x = 1786 + 66
- 2x = 1852
- x = 1852/2
- x = 926
So the rate of one plane is 926 km/h and of the other plane is:
First one is 72 the second one is 20 the third one is 12 I can’t really see it so good luck
Answer:
21,000
Step-by-step explanation:
front end estimation requires you to take the front / first digit of each number in this expression and round.
if you don't know how to round, basically you take the next digit after the first one, (in 719 you take the 1) and determine if that's below or above 5. If below, then keep the original first number. If above, add one more to the first digit. If the number is five itself, it is most common to round up (so add one).
like 425 would round to just 400; and 676 would round to 700.
multiply 700 and 30
youd get 21000
Answer:
6+5*(10-8)=16
Step-by-step explanation:
Using BODMAS multiplication takes precedence over addition and subtraction so as it stands it would be calculated as 6 + (5*10) - 8. To get the answer 16 it would be 6 + 5(10 - 8) Solving the brackets first, this gives 6 + (5*2) which gives 16.
