Answer:
Numbers are 28 and -15
Step-by-step explanation:
Mark first number X, and second number Y, then:
x-y=43
and
x+y=13
We get system of two equations. Solve it by add both them together:
x-y+x+y=43+13
2x=56
x=28 we get first number
x+y=13
28+y=13
y=13-28
y=-15
Answer:
4
Step-by-step explanation:
3*4+2=14
12+2=14

Answer:
Each stuydent must raise $15.61 to reach their goal.
Step-by-step explanation:
Their goal is 483.62, but they already have 218.25 so we subtract,
483.62 - 218.25 = 265.37
Since there are 17 students and they raise the same amount we need to divide by the amount of students to find out how much money each of them need to raise to add up to their goal.
265.37/17 = $15.61
