300=x+1.9x
I got this by dividing the problem into two parts x[the speed of the first half] plus 1.9x [the speed of the second half increased by 1.9] both of those together should give you 300.
I went further and solved this...If you placed 103.5 into this problem for x you should get 300.15!
2 1/3 - 2/3 would equal 1 2/3. Hope this helps!
Hope this answer helps you! If it did, please mark it as the brainiest! I would really appreciate it! :)
Write a system of equations and solve.
x + y = 10
5x + 10y = 90
Multiply and combine equations
-5x - 5y = -50
5x + 10y = 90
------------------
5y = 40
y = 8
x = 2
There are 2 nickels and 8 dimes in the jar. Hope this helps! :)
Answer:
Number of birds = 13
Explanation:
An animal shelter spends $1.50 per day to care for each bird and $3.50 per day to care for each cat.
Let the number of bird be 'a' and number of cat be 'b'.
Total money spent = 103.5
1.5 a + 3.5 b = 103.5 ------------------------equation 1
Total number of birds and cats = 37
a + b = 37 ------------------------equation 2
1.5 x equation 2
1.5 a + 1.5 b = 55.5 ------------------equation 3
equation 1 - equation 3
2 b = 103.5 - 55.5 = 48
b = 24
Substituting in equation 2
a = 37 - 24 = 13
Number of birds = 13, Number of cats = 24.
