Answer:
A 2:3
Step-by-step explanation:
6y:9y
We can divide the ratio by 3y on both sides, since 3y goes into both numbers
6y/3y: 9y/3y
2: 3
Answer:
705
Step-by-step explanation:
141 words in 2 minutes means 70.5 words in a minute
70.5 × 10 = 705 words in 10 minutes
Just multiply 9x9 then mutiply the answer by 9 and there you go
Answer:
7x-4y=-8.........(i)
y=3/4x-3........(ii)
Putting the value of y in eqn(i)
7x-4y=-8
or, 7x-4(3/4x-3)=-8
or, 7x-3x+12=-8
or, 4x=-8-12
or, x=-20/4
x=-5
again,
putting the value of x in eqn(ii)
y=3/4x-3
y=-5(3/4) -3
y=-15/4 -3
y=-3/4
x=-5
y=-3/4
