Answer:
Step-by-step explanation:
Hello, first of all we can divide by 2.
The discriminant is negative so there is no real solutions.
Thank you.
Answer:
20 percent
Step-by-step explanation:
Just divide 100 by 65 and multiply that number by 13.
Answer:
Step-by-step explanation:
<u>Use the interest formula:</u>
- I = Prt, where P - amount of loan, r- interest rate, t- time in years
<u>Robert:</u>
- I = 30000*(4.9/100)*4 = 5880
<u>Susan:</u>
- I = 30000*(4.5/100)*6 = 8100
<u>Difference in amounts of interest:</u>
Susan paid $2220 more
The larger number is 117.93, why is that the biggest number you might ask it is because the 9 is bigger than the 8.
Number of oranges is (2a + 2)
Half the number of oranges is 1/2(2a + 2)
Half the number of apples is 1/2a
The difference between half the number of oranges and half the number of apples equals 4 looks like this:
1/2(2a + 2) - 1/2a = 4
Now solve.
1/2(2a + 2) - 1/2a = 4 (multiply 1/2 by what's inside the parenthesis)
1a + 1 - 1/2a = 4
1a + 1 -1 - 1/2a = 4 - 1
1a - 1/2a = 3
1/2a = 3
1/2a ÷ 1/2 = 3 ÷ 1/2
a = 6
He has 6 apples.
Substitute 6 into the equation for the number of oranges.
2a + 2
2(6) + 2 = 14
He has 14 oranges.
Check your work.
The difference between half the number of oranges (7) and half the number of apples (3) does indeed equal 4.
Therefore, the equation has one solution.
