Answer:
A. 2f + 10 = 28
Step-by-step explanation:
28 candy bars.
He wants 10.
28 - 10.
18 candy bars.
He gives each friend 2.
18 divided by 2.
9.
He can treat 9 friends.
Step 1: Subtract 10 from both sides.
2f+10=28
which would take away the 10 and subtract 10 from 28. (That would be Jack's bars.)
2f = 28.
Step 2: Divide by 2 on both sides.
2f = 28
which would cancel out the 2f. And Whatever is done to the left is done to the right, meaning you would divide 28 by 2 aswell. (Dividing up the candy bars among his friends).
f = 9
Question 1)
there’s 180 degrees in a triangle
70 + 70 = 140
180 - 140= 40
A= 40
question 2)
there’s only one line of symmetry, down the middle
The speed to the island is x. The speed to return is x+5.
The distance is the same so, 2.5 multiplied by x = 2×(x+5).
It took 2.5 hrs to get there and 2 hrs to return. Now all we have to do is solve.
2.5*x = 2x + 10
.5x = 10
x=20
Therefore, the distance between islands is 2.5 × 20 = 50 miles.
hope this helps!
Well to find the area of a circle Pie times r^2. But If you already have the diameter, you could either split the diameter in half, and do the regulaur formula, OR you could ude this formula ----> Pie times The diameter
Ermm, Don't you think it's 60?
Cause in my caculatons it's 60
