Answer:
Step-by-step explanation:
a. p=2200+60n
b. p=2200+60(26)
p=2200 plus 1560
p=3760
Answer:
4x + 3y = 5
Step-by-step explanation:
Given
y - 11 = -
(x + 7)
Multiply through by 3
3y - 33 = - 4(x + 7) ← distribute
3y - 33 = - 4x - 28 ( add 4x to both sides )
4x + 3y - 33 = - 28 ( add 33 to both sides )
4x + 3y = 5

Answer:
12
Step-by-step explanation:
There are 4 different digits to choose from. Since we want 2-digit number, we will see what digits can we put in place of 1st digit and what digit can we place in place of 2nd digit.
Hence, <u><em>how many digits (from 1,5,6 and 8) can be placed in the 1st digit of the number we want?</em></u>
Any one of the four digits (1,5,6, or 8).
Now, <em><u>How many digits (from 1,5,6 and 8) can be placed as the 2nd digit of the number we want?</u></em>
Any one of the THREE digits (since repetition is not allowed, we disregard the initial digit).
Thus the number of two-digit positive integers is 4 * 3 = 12
Unknown values can be taken as anything , for example : the most common is x for unknown values and sometimes, for angles we can take θ(theta).
it is totally upto you!
