U just have to find original amount (100%) and that is the amount he made last week.
First, we're going to convert the mixed number into a/n improper fraction.
(4 × 8 ) + 4 = 36/8
Now we're going to divide 36/8 by 4/8 since 4/8 = 1 lap.
36 / 4 = 9.
That is how we get our answer, 9 laps.
Our final answer is 9 laps.
Hope this helps!~
Answer:
5 1/3 x+8 1/2 =3 1/3 ?
the correct answer is -1.774
Step-by-step explanation:
51/3x + 81/2=31/3 In order to find x, we follow BODMAS rule
so we have,[ 51/3] x + 81/2 =31/3
we have 51x/3 + 81/2=31/3
we collect the like terms;
51x/3= 31/3- 81/2
finding the lcm
51x/3= 2[31} - 3{81}/6
51x/3= 62-243/6
51x/3= -181\6
by using cross multiplication
we have;
6{51x}= 3{-181}
306x = -543
divide both sides by 306
we have;
x = - 1.774
check your answer from
306x=-543
306{-1.774}= -543
-543= -543
Answer:
10x-6
Step-by-step explanation:
Answer:
14x+30y-20
Step-by-step explanation:
14(x+y)=14x+14y
14y+y=15y+15y=30y
and there is no like terms for -20 and 14x so the answer is
14x+30y-20
