Answer:
C. 10
Step-by-step explanation:
8.9a+15=104
8.9a=104–15 (–15)
8.9a=89 (÷8.9)
a=89/8.9
a=10
Step-by-step explanation:
Number on is base
Two is diameter
Three is radius and diamater
Five is cubic
Four is pi and radius
( pls excuse my spelling )
P=$2.25+5*$1.50=$9.75
The total cost to park for 5 hours is $9.75
The sum of the angles of any triangle is 180 degrees, so we get the equation:
x = 6
Hope that helps!
Answer:
(0,-1),(2,5)
Step-by-step explanation:
3x-y=1
0.5+2x-1=y
Substitute the equation of y into the other equation
3x-(0.5+2x-1)=1
3x-0.5-2x+1=1
collect like terms
-0.5+x=0
Solve for x
x(-0.5x+1)=0
0=-0.5x+1
-1=-0.5x
x=2 x=0
Back substitute into the other original equation and solve for y
3(2)-y=1
6-y=1
y=5
(2,5)
3(0)-y=1
-1(-y)=-1(1)
y=-1
(0,-1)
