The product of a number y and 12 or 12 times a number y. These are both equivalent expressions to 12y
70 cm
ex:
100 cm in a meter
so you’d do 100-30 cm
and that equals 70 centimeters
Answer: 39
Step-by-step explanation: x=13. so 5-2=3 x 13 = 39
espero que esto ayude :)
+ √6 = √9
The first step is to get by itself. We can do this by subtracting 
from each side, and simplifying 
= 3 -
Now we square both sides
5x = (3 - )²
Using the formula (a - b)² = a² -2ab + b², (3 - )² = 15 - 6
5x = 15 - 6
x = 
Answer:
x = 17, y = 9
or as an ordered pair, (17, 9).
The equations are consistent.
Step-by-step explanation:
2x - 3y = 7
x - 2y = -1 Multiply this equation by -2:
-2x + 4y = 2 Add this to the first equation:
y = 9.
Plug y = 9 into the second equation:
x - 2*9 = -1
x = -1 + 18 = 17.
