The quotient of 4 ÷ 4 = 1
Hey there,
So we have to right an equation d=rg right?
So when d is the distance right?
And we know that the distance is 15.
So now we have 15=rg OK?
And g is the number of gallons of gas right? And he used half a gallon of gas.
So we have 15=r(1/2) right?
Now the thing is we don’t like fractions in equations so we have to get rid of it.
How can we change 1/2 into a whole number?
If we multiply by two we can get 1 right?
So we multiply by two.
When we multiply one side by two we also have to multiply the other side by two too to balance to equation out right?
So we have d(15)=r((1/2)2) right?
So we get 30=2r OK?
Now we are told we have to find r right?
If 30=2r r must be 15 right?
Because 30/2 is 15.
So we know that r is 15 now.
So we have the equation d=15g
Hope this helps
Answer:
f(x) = expression
f(2) = 14 means that your x-value is 2. when you plug in 2 for x, you get 14 as y.
Answer:
30.48 miles
Step-by-step explanation:
This can be represented as a right angle triangle with sides 20 miles and 23 miles. The hypotenuse is the distance from the starting point. Pythagoras theorem states that for a right-angled triangle, the square of side of the hypotenuse is equal to the sum of squares of the other two sides. It is given by the equation:
c² = a² + b², where c is the hypotenuse and a,b are the sides
Let a = 20 miles and b = 23 miles
c² = a² + b²
c² = 20² + 23²
c² = 400 + 529
c² = 929
c = √929 = 30.48
c = 30.48 miles
S=a-63
s+a=487, using s from above in this equation you get:
a-63+a=487 combining like terms
2a-63=487 adding 63 to both sides
2a=550 dividing both sides by 2
a=275
So there were 275 adult tickets sold.
