Please provide the other fraction so we can give you the right number or at least a picture.
Make an equation system based on the problem
eg. a is the first number and b is the seond number
An equation for "<span>The sum of two numbers is 53" is
</span>⇒ a + b = 53
An equation for "<span>twice the first number minus three times the second number is 26"
</span>⇒ 2a - 3b = 26
<span>
Solve the equations by elimination and subtitution method
Eliminate a to find the value of b
a + b = 53 (multiplied by 2)
2a - 3b = 26
--------------------------------------
2a + 2b = 106
2a - 3b = 26
------------------- - (substract)
5b = 80
b = 80/5
b = 16
Subtitute the value of b to one of the equations
a + b = 53
a + 16 = 53
a = 53 - 16
a = 37
The numbers are 16 and 37</span>
Answer:
Step-by-step explanation:
We are given that:
First term (a) = 5
common ratio (r) =1/3
So, the t of 7 term is 5*1/729=5/729
Answer:
x ≥ 21.5/19
Step-by-step explanation:
-1.5(4x + 1) ≥ 45 - 25(x + 1)
-6x - 1.5 ≥ 45 - 25x - 25
-6x + 25x ≥ 45 - 25 + 1.5
19x ≥ 21.5
x ≥ 21.5/19
Answer: 11 hours and 25 minutes
Step-by-step explanation:
Since she left at 7:10 am you can add 50 minutes and you will get 8, then all the way to 6 pm is 10 hours. Now you just have 50 and 35 minutes that you havent added to the total yet so when you add those two together you get 85. But there isnt 85 minutes in a hour so you would have yo break it down and you would get 1 hour and 25 minutes. Add 1 hour and 25 minutes to 10 hours and you get 11 hours and 25 minute. I hope that helps!
Sorry if you didnt under stand my explanation.
