Answer:
The numbers are 21 and 33
Step-by-step explanation:
54/2=27
27-6=21
27+6=33
Step-by-step explanation:
The formula is<em> y=mx+b</em>, with <em>m</em> representing the slope, <em>x</em> representing the <em>x </em>coordinate, and<em> b</em> representing the y-intercept. Since -⅓ is the slope, that means that the equation starts off as y=-⅓. We know that the y-intercept is where the line meets the y-axis, so the y-intercept is 9. Since 9 (the y-intercept) is being added, that means the equation is y=-⅓+9.
Answer:
y=-⅓+9
With 3 you will have 9pi
With 13 you will have 169pi
So 169/9 so 18,8
Answer:
Step-by-step explanation:
15x = 3·5·x
30y = 2·3·5y
The common factors are 3 and 5.
Greatest common factor = 3·5 = 15
change 90 minutes to hours = 90 minutes * 1 hour/60 minutes = 1.5 hours
1/2 ton / 1.5 hours = x tons /4 hours
use cross products
1/2 * 4 = x * 1.5
divide by 1.5 on each side
1/2 *4/1.5 =x
2/1.5=x
4/3
They will clear 4/3 tons
