5x - 4 = 47
Add '4' to both sides
5x - 4 + 4 = 47 + 4
5x = 51
Divide both sides by '5'
5x/5 = 51/5
x = 51/5 = 10 1/5 = 10.2
121 is the answer
75
The answer is 20.
x = -(47/67), or -0.7015
2X10 would work, as would 5X4.
x2 • (5x2 + x + 8)
The Commutative Property (of Multiplication) says that 4x5 = 5x4. So, If 4x5 = 20, then 5x4 will also be 20.
22a-23=2422a=24+2322a=47a=47/22a=2.13
Yes, you can use the facts about 5x4 and 1x4 to find 6x8. First, recognize that 6x8 can be broken down into (5+1)x8, which equals 5x8 + 1x8. Since 5x8 is the same as 5x(4+4), you can calculate that as 5x4 + 5x4, and then add 1x8 (which is 8). This way, you can use the known facts to help find the answer.
No It is not 5x4=20 and 5x100=500
They are: 1*47 = 47 which is a prime number
you add them together 112 + 47 ------- 159
