To multiply rational expressions you just multiply tops and multiply the bottoms so
5/2x+1 * 6/x = 30/2x^2+x
Answer:Hope this helps!
Number 1 = 2 and 1/8
Number 2 = 6 and 3/40
Number 5 = 4 and 2/6
Number 6 = 15 and 1/3
Step-by-step explanation:
2x-y=1 is also equal to y=2x-1 so then plug in 1 or x and so on to create a table
Answer:
when both bottom numbers on a fraction are the same at the lowest form
Step-by-step explanation:
example: 2/4 + 6/8 the common denomenator is 8 as both numbers go into it and you only have to times by 2 so answer would be 10/8 which is also 1 2/8
Answer:
balloons= 9
candles= 8
Step-by-step explanation:
let the number of balloons be x
and candles be y
So
15x+8y=192----------1
x+y=17--------------2
from 2, x= 17-y
put x= 17-y in 1
15( 17-y)+8y=192
255-15y+8y=192
solve for y
-7y=192-255
-7y=-63
x=63/7
x=9
put x= 9 in 1
9+y=17
y= 17-9
y=8.
