A pound of oranges cost x dollar => A pound of pears cost x+3 dollar
We have: 8x+4(x+3)=30 => 12x=30-12=18 =>x=1.5
5 pounds of pears cost: 5(x+3)=5(1.5+3)=5*4.5= 22.5 (dollar)
The answer to this question is 21
Assuming the two angles are supplementary, the angle measuring x is equal to 33.75, and the angle measuring 3x+45 is equal to 146.25.
Step-by-step explanation:
x+(3x+45)=4x+45=180
4x+45=180
-45 -45
4x=135
÷3 ÷3
x=33.75
3x+45=146.25
