Answer:
x=4/3 , x=-5/2
Step-by-step explanation:
6x^2 +7x=20
6x^2+7x-20=0
(3x−4)(2x+5)
3x-4=0 , 2x+5=0
3x=4 , 2x=-5
x=4/3 , x=-5/2
Answer:
See below
Step-by-step explanation:
You know that he spent 1/3 of his earnings, and then 1/4. After this, he has $28.90. You can write the equation like this:
1/4(x * 1/3) = $28.90.
If you need to solve it:
1/4 * 1/3x = 28.90
1/12x = 28.90
x = 346.80
Answer:
- row - F
- column - K
- column - S
- row - B
- column - K
- column - G
Step-by-step explanation:
1. The least four digit number found in the rows is : 1164
The row is F
2. The maximum number of digits in counting order is : 1 3 5 7 9
The column is K
3. The highest 3 digit number in a column is 992
The column is S
4. The palindrome with greatest number of digits is 7117
The row is B
5. The greatest number of odd numbers in counting order is : 1 3 5 7 9
The column is K
6. The palindrome with greatest number of digits is 235532
The column is G
You just change the mixed number into an improper fraction.
4 3/5
5x4=20
20+3=23
23/5
Step-by-step explanation:
Let's say c is the price of cinnamon tea, and s is the price of spice tea.
10c + 2s = 13
16c + 8s = 28
Divide the second equation by 4:
4c + 2s = 7
Subtract from the first equation:
6c = 6
c = 1
Use any equation to find s.
s = 1.5
Therefore, the cinnamon tea costs $1 per pound and the spice tea costs $1.50 per pound.
