Step-by-step explanation:
(x - 1)² = 50
Either x - 1 = +√50 or x - 1 = -√50.
Hence, x = +/-√50 + 1 = +/-(5√2) + 1.
Answer:
Step-by-step explanation:
Instead of dividing both sides by 5, it is multiplied
5x + 3 = 6 {Subtract 3 from both sides}
5x + 3 - 3 = 6-3
5x = 3 {Divide both sides by 5}
5x/5 = 3/5
x = 3/5
Answer:
Step-by-step explanation:
√x - 7 = 3 {add 7 to bothe sides}
√x - 7 + 7 = 3 + 7
√x + 0 = 10
√x = 10
Square both sides,
(√x)² = 10²
x = 100
To turn 105.6% into a decimal, we can remove the percent sign and divide by 100.
105.6 ÷ 100 = 1.056
Therefore, 105.6% can be written as the decimal 1.056.
Answer:
x = 3/2 or 1.5
Step-by-step explanation:
distribute 3 to the 2x and -1 by multiplying
6x - 3 = 6
add 3 to both sides to get 6x by itself and it keeps both sides equal
6x = 9
divide by 6
x = 9/6 = 3/2
x = 3/2
