The total of two numbers is 28. Four times the smaller number is 7 more than three times the larger number.
navik [9.2K]
Let's define:
x \ \textless \ y

So, you can set up a system of equations:
x + y = 28
4x = 7 + 3y

Now, to solve for both of those values, solve the system of equations:
x = 28 - y
4(28-y) = 7+3y
122-4y=7+3y
115 -4y = 3y
115 = 7y
y = 16.43

Now, plug that y-value into the first equation to solve for x:
x + 16.43=28
x = 11.57

Now, we have both the values. The smaller value (x) = 11.57 and the bigger value (y) = 16.43.

The sum of two consecutive integers is 99. Find the integers
Vadim26 [7]

Answer:

48

Step-by-step explanation:

The consecutive numbers will be x and x + 1. Then write out the equation 2x + 1 = 99

Collect like terms

2x = 99 - 1

2x= 98

divide both sides by 2

x = 49

The nth term of a sequence is 3n + 5
Scrat [10]

Answer:

5th term is 20

6th term is 23

4th term is 17

Step-by-step explanation:

So what you need to do is put the number that you are trying to get in the space of n. So if you want the 5th term, put the number in the n space. So it reads 3 5+ 5

Then times the 3 and the 5 that are next to each other that you put in the space of n

15+5

Then add them together so it’s 20

Hope that help.
