Answer:
y = -13.5
x = -10.5
Step-by-step explanation:
Hi there!
Let the two numbers be equal to <em>x</em> and <em>y</em>.
The difference of two numbers is 3 ⇒ x - y = 3
Their sum is - 24 ⇒ x + y = -24
Solve using elimination:
x - y = 3
x + y = -24
Add the two equations:
x + x - y + y = 3 - 24
2x = -21
x = -10.5
Solve for y:
-10.5 - y = 3
- y = 3 + 10.5
y = -13.5
I hope this helps!
The value of a is 72.74.
<h3>What is Probability ?</h3>
Probability is the study of likeliness of an event to happen.
It is given that
The mean 
of the distribution is 70
Standard deviation 
is 2
p( x<a) = 0.9147
a = ?
From Z table
For p ( p < 0.9147) , z = 1.37
a = 70+ 2*1.37
a = 72.74
Therefore the value of a is 72.74.

The numbers by themselves represent the amount of dollars spent (4 and 49), but since you don’t know the amount of money each candy bar cost, you would put the amount of candy bars and a variable next to it to then solve ($5 per bar)
