Answer:
X = 10 and X = -4
Step-by-step explanation:
(x-3)^2-38=11
(x-3)^2 = 11 +38
(x-3) ^2 = 49
Taking square root on both sides
√(x-3) ^2 = √ 49
X-3 = +7, -7
X = 7 +3, X= -7+3
X = 10 X = -4
So, it has got two solutions
Answer:
6
Step-by-step explanation:
because 3 pieces
divided by 2 because there half pieces.
The numbers decrease by 6.
-1, -8, -14, -20, -26, -32, -38, -44, -50, -56, -62, -68, -74, -80, -86, -92, -98, -104, -110, -116, -122, -128, -134, -140, -146
F: $30.05
172.90-52.71=120.19
120.19/4= 30.048 rounds to $30.05
Hope this helps!
To make this easier, we can convert the fractions into decimals. 3/4 is 0.75. 1 and 1/2 would be 1.50 and 2 and 1/4 would be 2.25. Now, let us to the subtraction in order for us to know the difference of each. So 1.50 minus 0.75 would be 0.75. And 2.25 minus 1.50 is also 0.75. 0.75 is 3/4 and this means that she increased 3/4 hour each day.
