you could either multiply straight away or you could simplify right then so that you wouldn't have to it later.
20/5 * 5/2
your answer would be 10 either way
Answer: in this question the easiest way to find an answer is by cross multiplying ....i hope i am right
Step-by-step explanation:
1 hour=25miles
9hours=x
cross multiply which will give u
1x=25x9
1x=225
x=
x=225miles
hope this helps
OR
1hour= 25miles
9hours=x
so u know in 9hours the miles swam will obviously will be more so if it is more less will divide
which will be=
×21 =225 miles
HOPE THIS HELPSSSSSSSSSS!!!!!!!!!!!!!
Answer:
B
Step-by-step explanation:
The inequality is
3x-5y>=10
You can substitute each of the choices in the inequality (on the left side) to see if the result is >=10.
A: 3(1)-5(4)=3-20=-17 not good.
B: 3(6)-5(-3)=18+15=33 good
Answer:
Step-by-step explanation:
take two points to find the equation:
(0,4),(-2,0)
y= 2x+4
domain is where the equation is defined ( x inputs)
Range is the set of values that correspond with the domain(y outputs)
the domain and the range are all real number
domain(-∞,∞) , range (-∞,∞)
.hello :
<span>2d−e=7....(1)
d+e=5.....(2)
(1)+(2) : 3d=12
d=4
subsct in (2) :
4+e=5
e=1
conclusion :
