Answer:
Let x represents the Sara eat pancake and y represents the Phil eat the pancake.
As per the statement:
Phil ate three less than twice as many pancakes as Sara.
"Twice as many pancake as Sara" means 2x
"three less than twice as many pancakes as Sara" means 2x -3
⇒
.....[1]
It is also given that together they combined to eat 15 pancakes.
⇒
.....[2]
Substitute equation [1] into [2] we get;
Combine like terms;
3x-3 =15
Add 3 to both sides we get;
3x = 18
Divide both sides by 3 we get;
x = 6
Substitute the value of x in [1] we get;
y = 2(6)-3 = 12-3 =9
y = 9
Therefore, the pancakes did each eat are;
Sara eat pancake = 6 and Phil eat pancake = 9
No
put 11 for p
add exponents. base stays the same
multiply exponents. base stays same
answer:
His answer is inncorrect becase he added the exponents 12 and 3 instead of multiplying. You multiply exponents when one is raised to another.

Answer:
After travelling 360 miles, 15 litres of petrol will be left.
Step-by-step explanation:
If a car can travel 480 miles with a full tank of 60 liters of petrol, it could be said that each liter of petrol allows to travel 8 miles (480/60 = 8). Therefore, since the driver has driven his car for 360 miles, his tank has spent 45 liters of petrol (360/8 = 45). In conclusion, given that the tank has a capacity of 60 liters and that it was full at the time of departure, having spent 45 liters, 15 liters remain in the tank.
Answer:
Slope: y2-y1/x2-x1
-5+3/-6-6 = 1/6
y+3 = 1/6 (x-6)
y+3 = 1/6x - 1
y=1/6x-4
Step-by-step explanation:
(6x - 5) - (3x - 2)
Distribute (multiply) the negative sign to (3x - 2).
6x - 5 - 3x + 2
Combine like terms; 6x - 3x and -5 + 2.
3x - 3 is your answer.
