The answer is 3. you have to divide the number by the denominator then multiply by the numerator
Answer:
Step-by-step explanation:
So he has $100 and you want to see how many golf balls he can purchase well we know he spends $75 on the clubs so
75
-100
--------
25
John now has 25 dollars left. One ball is $1.50 so we keep adding or multiplying till we finish 25 dollars
1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 = 24
or
1.50
x 16
----------
24
he can purchase 16 golf balls
and the reason why it's 16 is that 16 golf balls are equal to 24 dollars and he can't purchase 17 golf balls or else that would be $25.50 which is more money than he has.
Hope that helped!
Answer:
x = 4
, y = 3
Step-by-step explanation:
Solve the following system:
{2 x - 3 y = -1 | (equation 1)
y = x - 1 | (equation 2)
Express the system in standard form:
{2 x - 3 y = -1 | (equation 1)
-x + y = -1 | (equation 2)
Add 1/2 × (equation 1) to equation 2:
{2 x - 3 y = -1 | (equation 1)
0 x - y/2 = (-3)/2 | (equation 2)
Multiply equation 2 by -2:
{2 x - 3 y = -1 | (equation 1)
0 x+y = 3 | (equation 2)
Add 3 × (equation 2) to equation 1:
{2 x+0 y = 8 | (equation 1)
0 x+y = 3 | (equation 2)
Divide equation 1 by 2:
{x+0 y = 4 | (equation 1)
0 x+y = 3 | (equation 2)
Collect results:
Answer: {x = 4
, y = 3
