Just finished doing the math and the correct answer should be B: 5.3 Hope this helps:)
Answer: 3.3 per minute
Step-by-step explanation:
46.2 / 14.0 = 3.3
3.3 * 14.0 = 46.2
Hope this helps you!
Step-by-step explanation:
let the first number be x
let the second number be y
½ of the first number= ½x
Double the second; 2*y=2y
the sum... that is ½x+2y=14
Answer:
11. 135 mph
12. 40 Oz
13. 50 m
14. 2500
15. 240
i don't know 16
Step-by-step explanation:
11. 27 x 5= 135 mph
12. 24 : 6 x 10= 40 Oz
13. 1.5 : 3 x 100= 50 m
14. 40% = 1000
10% = 250 (1000 : 4 = 250)
100%= 2500 (250 x 10 = 2500)
15. 75% -> 25% = : 3
180 : 3 = 60
180 + 60 = 240
The answer should be f(x)=20(2.5)^x
How?
the graph crosses the f(x) axis at 20 but that's common in all 4 equations. However, when x=1, f(x)=50. We have to know try all the equations by substituting these values in ( both sides are equal).
f(x)=20(2.5)^x
substitute f(x)=50, x=1
50=20(2.5)^1
50=20*2.5
50=50
