1. I would first write it out as fraction
2/1 divided by 2/5
2. When dividing fractions you need to find the reciprocal (opposite of or switched) of the fraction then multiply the two fractions together
2/1 divided by 5/2 <------- that's the reciprocal of 2/5
3. Now multiply
2 5 10
- x - = - = 5
4. 5 is your answer! :)
1 2 2
Answer:
x=6 2/5
Step-by-step explanation:
I don't know how to explain other than doing the math of (x*5)/2=16
I'm not sure how many equations you are asking for, but hopefully, you can use what I wrote here to solve your actual question. Here is my go:
3x+10+2x+2+5x
First, add all the x's together:
3x+2x+5x=10x
Next, add all our numerals together:
10+2=12
Put it together!
10x+12
All you need to do is replace the variables with the numbers given.
t=9 & u=11
3+ 11t - 9u
3+ 11(9)-9(11)
3+ 99 - 99
The 99's cancel each other out, so you are left with 3.
The answer is 3.
Answer:
y = 1
x = -3
Step-by-step explanation:
9x + 2y = 3
-x - y = -12 (multiply second equation with 9)
9x + 2y = 3
-9x - 9y = - 108 (add these to up)
-7y = -105
y = 15 use this to find x
9x + 2y ➡ 9x + 30 = 3 ➡ 9x = -27 ➡ x = -3
