Answer:15
Step-by-step explanation:
27+x=42
Collect like terms
x=42-27
x=15
90+(3x-14)+x=180
(3x-14)+x=90
3x+x=104
4x=104
x=26
The answer is 32,000,because 5,339 times 6 is 32,034.
Answer:
y = 2
x = 5
Step-by-step explanation:
4x + 5y = 10 | ×3 |
3x - 3y = 21 | ×4 |
12x + 15y = 30
12x - 12y = 84
____________--
27y = -54
y = -54/27
y = 2
4x + 5y = 10 | ×3 |
3x - 3y = 21 | ×5 |
12x + 15y = 30
15x - 15y = 105
____________+
27x = 135
x = 135/27
x = 5
15/20
convert to a decimal
0.75
multiply 0.75 by 100 to convert to a percentage
0.75 * 100
simplify 0.75 * 100
your answer is 75%
