Answer:
They are 5,6 and 7.
Step-by-step explanation:
Let the integers be x, x+1, x+2.
x + x + 1 + x + 2 = 2(x + 2) + 4
3x + 3 = 2x + 8
x = 8 - 3 = 5.
Answer:
B. 60
Step-by-step explanation:
There are a total of 200 students here, and 45% got Cs, to find how many got Cs, multiply 200 by 45%, or 0.45: 200*0.45 = 90, 90 people got Cs.
15% got Ds, multiply 200 by 15%, or 0.15 to get 30, 30 got Ds
The amount who got Cs minus the amount who got Cs is 90 - 30 = 60, 60 more students got Cs than Ds

Answer:
B
Step-by-step explanation:
First off, we see that x ≥ -2. That little horizontal line right under the > sign indicates that x is "greater than or equal to" -2. Because we want to include -2 in the solution set, the dot on the number line at -2 should be shaded in.
This already eliminates A and D.
Now, we're left to choose between B and C.
Well, we know that x is greater than or equal to -2, so possible values of x should be numbers that are more positive than -2, or that point in the positive direction. That's exactly what B illustrates, so that's our answer.
Answer:
Alabama: 1,700 sq miles
Florida: 12,000 sq miles
Hawaii: 4,500 sq miles
Michigan: 40,000 sq miles
Florida/Hawaii Difference: 7,500
Michigan/Alabama Difference: 38,300
Step-by-step explanation:
1.7 x 10^3 = 1,700
1.2x10^4=12,000
4.5x10^3=4,500
4.0x10^4=40,000
