So to find the answer you want to isolate the y. So the first thing you want to do is to move everything to the opposite side of the = sign. You start by adding 10 to both sides.
10+ 5y -10 = -25 +10
5y = -15.
the tens cancel out on the left side and on the right you get left with -15/
Since y is being multiplied by 5 you always want to do the opposite so you divide by 5.
5y/5 = -15/5
y = -3
It's hard to explain but you just have to remember that what you do to one side you must do to the other to keep the equation balanced.
Answer:
1/5
Step-by-step explanation:
There are 3 numbers of less than 4 (1, 2 and 3) and there are 2 multiples of 9 (9 and 18). So there are 5 favourable outcomes and 25 possible outcomes. So you put 5/25 and cancel down, which makes 1/5. I hope this helps!
Answer:
Split the number into the whole number component and fraction component.
5 8/25= 5+8/25.
For the denominator, recognize that
25×4=100.
Multiple =4.
Multiply the numerator and the denominator by the multiple 4.
8×4/ 25×4.
Simplify.
32/100=0.32
Combine the whole number component with the decimal.
5+0.32=5.32
