Answer:
x=7.5
Step-by-step explanation:
To solve this, cross multiply
3/4=x/10
4*x=3*10
4x=30
Divide by 4 on both sides
x=7.5
Hope this helps! :)
Answer:
when y=3,X=15
here X is five times the value of y
so now when y= 5 then the value of X will be 25
hope you understand......
1:40.
1:40 is equal to 1/40, while 1:60 is equal to 1/60.
1/40 is the bigger fraction, so 1:40 is the correct answer.

Start with the expanded array:
then using the tool provided, make row operations until you find the solution:
r2 = r2-3r1
r3 = r3+2r1
r2 = r2*(-1/13)
r1 = r1- r2*5
r3 = r3+ r2*-3
r3 = r3*13/168
r2 = r2- r3*22/13
r2 = r2+ r3*6/13
Here you have a reduced array an therefore the answers to each variable are on each row:
