Answer:
x = 10
y = 9
Step-by-step explanation:
First, you need to write two equations that represent the information given. I'm going to set the two numbers and x and y.
x - y = 1
x + y = 19
This turns it into a systems of equations. When you add the two equations, keeping everything on each side, you eliminate a variable, and solve for the other.
2x = 20
x = 10
Now, you'd plug x into either original equation.
(10) - y = 1
-y = -9
x = 10
I hope this helped!
Answer:
Grace could buy 1 or 2 bananas and not more than that and hence she cannot make the total count of fruits tleast 13.
Step-by-step explanation:
Cost of 1 banana = $0.5
Cost of 1 mango = $0.75
Total money Grace has = $7.25
Grace has decided to buy 8 mangoes costing = 8 \times 0.75
= $6
Grace has to buy a minimum of 13 mangoes and bananas altogether.
After Grace buy 8 mangoes , money remaining with her = 7.25 - 6
= $1.25
With the remaining money she has to buy bananas which cost her $0.5 each.
With $1.25 she can buy a maximum of 2 bananas only and the total number of fruits equals 10.
Hence it is not possible to buy 13 fruits altogether.

Answer:
25deg 55deg 100deg
Step-by-step explanation:
There are 180deg in a triangle. We know one angle is 30deg more and the other 75deg more than the smallest angle so we subtract that from 180.
180-75-30 = 75
We divide 75deg by 3 because there are 3 angles.
75/3 = 25
So we know the smallest angle is 25deg. We have to add 30deg to one angle and 75 to the other in oder to find the remaining angles.
25+30 = 55deg
25+75 = 100deg
So the angles are 25deg, 55deg, and 100deg.
