R-9s=2 add 9s to both sides
r=2+9s making 3r-3s=-10 become:
3(2+9s)-3s=-10 perform indicated multiplication on left side
6+27s-3s=-10 combine like terms on left side
6+24s=-10 subtract 6 from both sides
24s=-16 divide both sides by 24
s=-16/24
s=-2/3, making r-9s=2 become:
r-9(-2/3)=2 perform indicated multiplication on left side
r+6=2 subtract 6 from both sides
r=-4
So s= -2/3 and r= -4
The answer is 412,987

Answer:
s = 65/3 pi
Step-by-step explanation:
The length of the intercepted arc is given by the formula
s =r*theta when theta is given in radians
r = 13
theta = 5 pi/3
Substituting what we know
s = 13 * 5 pi/3
s = 65/3 pi
Since we want an exact answer, we have to leave it in terms of pi and as a fraction
Answer:
Step-by-step explanation:
Let required amount be x
<u>Using the ratio to find x:</u>
- 1 1/2 ÷ x = 1/3 ÷ 1
- x = 1 1/2 × 3
- x = 3/2×3
- x = 9/2
- x = 4 1/2 cups
Answer:
25%
Step-by-step explanation:
To change a fraction to a percentage multiply the fraction by 100%, thus
× 100%
=
= 25%
