Answer:
x=9.5, y=5.75
Step-by-step explanation:
2x-5=14, 3x+2y=40
focus on 2x-5=14 first:
2x-5=14 (add 5 to both sides) 2x=19(divide both sides by 2) x=9.5
Now subtitute x into the second equation and find y:
3(9.5)+2y=40(simplify) 28.5+2y=40(subtract 28.5 on both sides) 2y=11.5(divide both sides by 2) y=5.75
Answer:
99 marbles
Step-by-step explanation:
Let number of marbles with Alex be
Leanne has 1/2 as many marbles as Alex.
So,
Number of marbles with Leanne =
Number of marbles with Joachim =
Also, Alex has 36 more marbles than Joachim.
So,
Number of marbles with Alex = 36 + Number of marbles with Joachim
=
So,
So,
Number of marbles with Alex = 54
Number of marbles with Leanne =
Number of marbles with Joachim =
Total number of marbles =

Answer:
The midpoint is ( 1, -1.5)
Step-by-step explanation:
To find the midpoint
Add the x coordinates of the endpoints and divide by 2 to get the x coordinate of the midpoint
(5+-3)/2 = 2/2 = 1
Add the y coordinates of the endpoints and divide by 2 to get the y coordinate of the midpoint
(3+-6)/2 = -3/2 = -1.5
The midpoint is ( 1, -1.5)
