Answer:
17
Step-by-step explanation:
since you are subtracting a negative number it reverses, so you actually ADD the two together
so, 12 1/2 + 4 1/2
add the whole numbers first;
12+4=16
then fractions:
1/2 + 1/2= 1
then all together;
16+1=17!
Solution: We are given that the population of Virginia is 8 million.
Let x be the population of Nevada.
We are given population of Virginia is 2.8 million less than 4 times the population of Nevada.




The first step is to on both sides.
add 2.8
The second step is to on both sides.
divide 4
The population of Nevada is million.
2.7
28x+86≤200 because for supplies they divide the rest of money. that means, 200-28=172 so 172/2=86 now we gonna find the value of x.
28x+86≤200 i am gonna subtract 86 both of side 28x+86-86≤200-86 to get value of x.
28x≤114 divide 28 both of side to get value of x so it will be x≤4
