Answer:
The value of r=
The value of x=
Step-by-step explanation:
Given that,
A) 
Now,
8(2r-2)=9(7r+10)
16r-16=63r+90
-16-90=63r-16r
-(16+90)=47r
-106=47r
r=
B) 
Now,
5(x+5)=9[3(x-2)-1]
5x+25=9[3x-6-1]
5x+25=9[3x-7]
5x+25=27x-63
25+63=27x+5x
83=32x
x=
Answer:
yes
Step-by-step explanation:
For which problems? Just number one or all?
Answer:
16:4 or 4:1
Step-by-step explanation:
Since it says cups to quarts, the first number in the ratio would be the cups which are 16. The next portion or the ratio is the quarts or 4.
Since a ratio is meant to show a relation between numbers or substances, this ratio would essentially show just that.
However, it could be simplified further by divided both sides by 4.
Hope this helps!
