U should get the app "photomath" it will help u out alot!!!
Answer:
125 %
Step-by-step explanation:
Computers purchased in the last month = 8
By the middle of the current month, 8 more computers than the last month were purchased. This means, total number of computers purchased by middle of current month = 8 + 8 = 16
Number of computers purchased by end of current month = 2
So,
Total computers purchased by current month = 16 + 2 = 18
We have to find the percentage increase in the number of computers from last month's purchases to the end of this month's purchases. The formula for percentage change is:
Here, Original Value is the number of computers from last month and New Value is the number of computers from current month. Using the values in the formula, we get:
Thus, there was a 125% increase from last month's purchases to the end of this month's purchases
From the description we can infer that we have the expression:
.
Now, to write our expression as a as a root, we are going to apply the law of exponents:
first
Next, we are going to apply the law about fractional exponents:
We can conclude that the
value of B is 2.
X = y + 5
(x + y) = 3y - 3
y + 5 + y = 3y - 3
2y + 5 = 3y - 3
5 + 3 = 3y - 2y
8 = y
x = y + 5
x = 8 + 5
x = 13
ur numbers are : 8 and 13
Okay so you make your own kind of number, add the two number together. then graph the number on the chart verifying where its at . go from the origin and fine out where your number stands. then make sure your equations can prove that what number you picked and were you put them made the answer true
hope this helped!
