Answer:
Step-by-step explanation:
If the triangle is equilateral :
2x +y/2 = 5x/3+y + ½ = 2/3x +2y +5/2
so the perimeter is : P = 3(2x +y/2) or 3(5x/3+y + ½) or 3(2/3x +2y +5/2)
the simplest is : P = 3(2x +y/2)
P = 6x + (3y)/2
Y= the number riders over time
x= hours into Tara's shift
y= 33x + 132
Answer:
Required equation is: 25n = 875
Step-by-step explanation:
Let n be the number of minutes Jonathon read per day
Now
He read for 25 days and total 875 minutes
The equation will be:

We can solve this equation to find the number of minutes each day
Using Division property of Equality

Hence,
Required equation is: 25n = 875
1 x
---- = -----
8 1224
8x = 1224
x = 153
Answer:
the answer is -3x² caused when -x divide with 3x it will became -3x²
