Answer:
x=15
Step-by-step explanation:
3(x-5)=30
First, you would distribute the three to the x and the negative five.
3x-15=30
Then you would add 15 to the 15 to cancel it and to the 30 to make it even.
3x-15=30
+15=+15=
3x=45
Finally, you would divide 3 into both sides, cancelling out the three and fiving you,
x=15
Hope this helped!
Answer:
12:16
Step-by-step explanation:
Add the miniature balls.
3 + 9 = 12
There are 16 black marbles in the jar.
Therefore, the ratio of miniature balls to the number of black marbles is 12:16.
Fifteen more means somewhere we’ll add 15. Two times as many as c = 2c. So,
2c + 15 = how much candy Michelle has
2c + 15 is the answer
