Answer:
-9n
Step-by-step explanation:
3n(5 + 3n - 8 - 3n)
First we combine the like terms inside the parenthesis:
3n(-3)
Because 5 -8 = -3 and 3n - 3n = 0
Now we multiply:
-9n
because 3n × -3 = - 9n
So the answer is -9n
2/8 ÷ 2
1/4
2/8 in simplest form is = 1/4
and
5/8 in simplest form
5/8
5/8 = 0.625 as a decimal form
5/8 = 0.63 in 2 decimal places
5/8 = 0.6 to the nearest tenth
5/8 = 0.63 to the nearest hundredth
5/8 = 0.625 to the nearest thousandth
4*20 is 80. 2*5 is 10.
There would need to be 90 meatballs.
Second and forth because all the others can be simplified
Answer:
- A. Since 11 ≠ 9, there is no solution
Step-by-step explanation:
<u>Given system:</u>
- 1.75x + 1.25y = 2.75
- 7x + 5y = 9
<u>Multiply the first equation by 4:</u>
- 4(1.75)x + 4(1.25)y = 4(2.75)
- 7x + 5y = 11
We get same equation as the second one with the difference that the right side equals to 11.
Since left sides are same and right sides are different, the system has no solution.
Correct choice is A
