The numbers are "x" and "y",
we suggest this system of equations.
x+y=24
x-y=15
solve by reduction method.
x+y=24
x-y=15
-----------------
2x=39 ⇒x=39/2=19.5
x+y=24
-(x-y=15)
-------------------
2y=9 ⇒y=9/2=4.5
The numbers are 19.5 and 4.5
To check
19.5+4.5=24
19.5-4.5=15
Let the number of pyramids be x, then
3(4)x = 576
12x = 576
x = 576/12 = 48
He can make 48 pyramids.
Step-by-step explanation:
Compounded monthly means n=12
Answer: The total cost was $1,682.70
Step-by-step explanation:
Before tax: $1,580
Sales tax: 6.50% or $102.70
After tax: $1,682.70
If we know that the angle on the left is 80° we know that the angle on the right is also 80°
We can subtract these from 360° and we are left with 200°
Since all four of the remaining angles are congruent we can divide our remaining 200° by 4
When you do that you get 50, meaning each remaining angle is 50°
Making x=50°
Hope this helped!
