In the given problem there are several vital informations to take note off for completing the required answer to the question.
It has been assumed that the unknown number is = p
Now we can get to the desired equation for solving and finding the value of p.
(p + 7)/12 = 3
p + 7 = 3 * 12
p + 7 = 36
p = 36 - 7
= 29
So the value of the unknown number p is 29. I hope that the method i have used to solve this problem is clear to you and you can solve such type of problems in future without anyone's help.
Answer:
a)x=5; b)x=4
Step-by-step explanation:
a) 4x-3=2x+7
=>4x-2x=7+3
=>2x=10
=>x=5 [divide both by 2]
b)2x+6=7x-14
=>7x-2x=6+14
=>5x=20
=>x=4 [divide both by5]

Answer:
3x18 = 3 (10+8) is an example of the commutative property of multiplication
Step-by-step explanation:
Step1. find the how much he buy he buy 45
step2. find the % the % is 4 move to decimal left 4% which is .04
step3. multilply the how much he buy or the % so this is that 45*.04=1.8
step4. what are they said they said tax is like add so we got 1.8+$45=46.8
so the answer is 46.8
look at what is the step and you understand the problem more easy way.
