Answer:
balloons= 9
candles= 8
Step-by-step explanation:
let the number of balloons be x
and candles be y
So
15x+8y=192----------1
x+y=17--------------2
from 2, x= 17-y
put x= 17-y in 1
15( 17-y)+8y=192
255-15y+8y=192
solve for y
-7y=192-255
-7y=-63
x=63/7
x=9
put x= 9 in 1
9+y=17
y= 17-9
y=8.
Answer:
p = - 5i or p = 5i
Step-by-step explanation:
Noting 
= i
Given
p² = - 25 ( take the square root of both sides )
p = ± 
= ± 
= ± 5i
Thus
p = - 5i or p = 5i
Uh do you mean he earned $225 per week?
If yes, then he earned 45 per day.
Answer:
a right angle
Step-by-step explanation:
The best and most correct answer among the choices provided by the question is the second choice "a right angle"The formula for finding the slope of a line on a coordinate plane is (y2 - y1) / (x2 - x1), where (x2, y2) and (x1, y1) represent two distinct points on the line. This is also known as "change in y over change in x" or "rise over run."I hope my answer has come to your help. God bless and have a nice day ahead!
Answer:
x=28
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x+5+x−5=56
x+5+x+−5=56
(x+x)+(5+−5)=56(Combine Like Terms)
2x=56
2x=56
Step 2: Divide both sides by 2.
2x/2=56/2
x=28
