2 triangle+square=23
square=60/triangle
2 triangle+60/triangle=23
2 triangle^2+60=23 triangle
2 triangle^2-23 triangle+60=0
solving quadratic equation we get
triangle=15/2 , 4
15/2 is not possible so triangle=4
square=15

Answer:
(-4,5)
*View attached graph*
Step-by-step explanation:
y = -2x - 3
4y + x = 16
4y + x = 16
4(-2x - 3) + x = 16
-8x - 12 + x = 16
-7x - 12 = 16
+12 + 12
-7x = 28
/-7 /-7
x = -4
4y + x = 16
4y + (-4) = 16
4y - 4 = 16
+ 4 + 4
4y = 20
/4 /4
y = 5
(x,y) -> (-4,5)
Hope this helps!
Answer:
Step-by-step explanation:
.25 mile in 2 mins
.25(5) miles in 10 min
1.25 mins in 10 mins
There is 5-2 mins in 10 mins. So times by the 5.
