Answer:
11 2/3
Step-by-step explanation:
2 1/3 * 5
Change the mixed number to an improper fraction
2 /13 = ( 3*2+1)/3 = 7/3
7/3 * 5/1
35/3
Now change it back to a mixed number
3 goes back into 35 11 times with 2 left over
11 2/3
Answer:
If you're solving for x, the answer is -50. x = -50
Step-by-step explanation:
Remove the parenthesis and distribute:
-5(x-8) + 7(x+3) = x + 11
-5x + 40* + 7(x+3) = x + 11
-5x + 40 +7x + 21* = x + 11
Collect like terms and calculate:
| -5x + 7x
2x + 40 + 21 = x + 11
| 40 + 21
2x + 61 = x + 11
Move them to the other side like so:
2x - x* + 61 = 11
| -61
2x - x = 11 - 61
Combine:
x = 11 - 61
x = -50
Answer:
X=20
Step-by-step explanation:
The answer is C
The number of decorative pillows did the realtor arrange on each twin bed and queen bed is 6 and 9 respectively.
<h3>Simultaneous equation</h3>
let
- Number of decorative pillows for twin bed = x
- Number of decorative pillows for queen bed = y
x + y = 15
2x + y = 21
From equation (1)
x = 15 - y
- Substitute x = 15 - y into (2)
2x + y = 21
2(15 - y) + y = 21
30 - 2y + y = 21
- 2y + y = 21 - 30
-y = -9
y = 9
Substitute y = 9 into
x + y = 15
x + 9 = 15
x = 15 - 9
x = 6
