How many times does 7 go into 74 without going over? 10 times.
7 * 10 = 70. 74 - 70 = 4. Bring down the 2. How many times does 7 go into 42? 6 times. 7 * 6 = 42. 42 - 42 = 0.
The quotient is 106.
Answer:
One gallon cost $3.20
Step-by-step explanation:
You know that 4 gallons are %16.80.
So, you divide 16.80 by 4,
16.80÷4
=3.2
Conclusion, 1 gallon is $3.20
Answer:
u = x²
Step-by-step explanation:
4x⁴ − 21x² + 20 = 0
Substitute u = x² to turn the equation into a quadratic.
4u² − 21u + 20 = 0
You can solve by factoring.
(4u − 5) (u − 4) = 0
u = 5/4 or 4
x² = 5/4 or 4
x = ±½√5 or ±2
To solve this, do Betty's points (68) and subtract them from Debbies's (e) to get the expression 68-e.
