Answer:
9
Step-by-step explanation:
3/7 multiplied by 21 = 3/7 x 21 = 9 = 3/7 x 21/1 = 63/7 = 9
Or if you can't do the math - Think of a pizza with 21 slices . Now cut this pizza into 7 equal parts. You will find that each part contains exactly 3 slices. Now, eat 3 of these parts. With three slices in each part, you ate 9 slices - which is three sevenths of 21.
Answer:
ok
Step-by-step explanation:
1) 
= 1.5 because the numerator goes int the denominator 1 time and then you ahve left over 
which is .5 .
2) 
= 2.5 because the 5 goes into the denominator 2 times and then you have left over .5 .
3) 
= .25 because a 1 is divided by 4.
4) = .5 ; a 1 is divided by 2
5) 
= .75 because you have .25 x 3 .
6) 
= .2 because it is 1 divided by 5
7) 0.04 + 4.1 = 4.14
8) 6.93 - 1.2 = 5.73
Answer:
(a + 5)(a + 2)
Step-by-step explanation:
Consider that 2*5 = 10 (the constant term) and that 5a + 2a = 7a (the x term).
Then a^2 + 7a + 10 = (a + 5)(a + 2)
