Answer:
y=10x-5
Step-by-step explanation:
should be the right answer since I used a calculator :p
Let x be the 1st number
x + 9 be the second number
Equation:
x + x+9 = 171
Solution:
2x + 9 = 171
2x = 171 - 9
2x = 162
x = 81
x + 9 = 90
81 + 90 = 171
Answer:
210
Step-by-step explanation:
Here comes the problem from Combination.
We are being asked to find the number of ways out in which 3 students may sit on 7 seats in a row. Please see that in this case the even can not be repeated.
Let us start with the student one. For him all the 7 seats are available to sit. Hence number of ways for him to sit = 7
Let us see the student second. For him there are only 6 seats available to sit as one seat has already been occupied. Hence number of ways for him to sit = 6
Let us see the student third. For him there are only 5 seats available to sit as two seat has already been occupied. Hence number of ways for him to sit = 5
Hence the total number of ways for three students to be seated will be
7 x 6 x 5
=210
Answer:
Step-by-step explanation:
The midpoint is essentially a point with the average of the 2 x-coordinates and the 2 y-coordinates.
The formula is:
We are given two points: A (7,0) and B (0, 3). Remember points are written as (x, y).
Therefore,
Substitute the values into the formula.
Solve the numerators first.
The midpoint can be left like this because the fractions are reduced, but it can be written as decimals too.
You must use distributive property to get 2m+10+48m+8 and then add all like terms. You get 50m+18 as your final answer.
