Answer:
2/21
Step-by-step explanation:
2/7 ÷3
sorry if wrong
2/7 * 1/3
2/21
The ratio is 5:3
As the information tells us, for every 5 cups of water, there are 3 cups of rice. So no matter what, the ratio will always be 5:3.
Answer:
n=t²
Step-by-step explanation:
2²=4
3²=9
4²=16....
So the equation is n=t².
1a (you don’t necessarily need to include the 1, so you can just put “a” if you’d like).
Answer:
1: x=y-3 linear equation : y=x+3
2:y=-2x-3 linear equation : y=-2x-3
3: -4y+6 =2 linear equation : y=2-6/-4 ⇒ y=1
4:2/3 x-1/3y=2 , linear equation : y=2x-6
-1/3 y=2-2/3 x
y=-6+2x
13: 5x+25=y² not linear
y = √5x+25
14 : 8+y=4x linear y=4x-8
15: 9xy-6x=7 not linear
16: 4y²+9=-4 ⇒ y²=-4/4 -9/4 ⇒y=√-1-2.25 ⇒y=√-3.25 not linear
17: 12x=7y-10y linear : y=12x/-3 ⇒ y=-4x
18:y=4x+x linear y=5x
