Answer:
B: 4 solutions
Step-by-step explanation:
Combining the two equations results in 2x² = 52, or x² = 26.
This equation has two solutions: x = ±√26.
As before, x² = 26. If we substitute 26 for x² in the 1st equation, we get:
26 - 4y² = 16, or 4y² = 10, or y = ±√5/2. Again: two solutions.
If we take x to be +√26, y could be ±√(5/2).
Check: is ( √26, √(5/2) ) a solution of the system?
Subbing these values into the first equation, we get:
26 - 4(5/2) = 16. Is this true?
Then 10 = 10. Yes.
Through three more checks, we find that this system has FOUR solutions.
Answer:1695.75
Step-by-step explanation:
We know that there are 7 days in a week. Since 57 people rent skates each day, we know that 57*7=399 skates are rented each week. Since one skate cost 4.25, we know that 399*4.25 is the cost, which is 1695.75. (If you are not allowed to use a calculator, you can do 400*4.25-4.25, to make it easier to compute)
<h3>If the divisor is 4 and the quotient is 8, Then, dividend is 32</h3>
<em><u>Solution:</u></em>
Given that,
Divisor = 4
Quotient = 8
To find: dividend
We know that,
Therefore,
Thus, dividend is 32
Answer: $88.00 per week
Step-by-step explanation: 10% of 22 is 2.2. 22 + 2.2 = 24.20 per hour
Multiply 24.20x40hours = 968.00
Multiply 22.00x40 hours =880.00
Subtract 968-880=88.00 his new weekly pay minus his old weekly pay
Answer: 30 miles
I am right.
