So, let me break it down.
you can simplify the fractions. like the 4 and the 8. you can simplify it into 1 and 2. so it would be 1/7×2/2.
Then you just multiply. 1×2=2 and 7×2=14
put it together and you get 2/14 or, as a more simplified version, 1/7

Answer:
umm 5:3?
Step-by-step explanation:
5:3+5:3=10:6
1: one solution
Explanation: We see that the variable x is equal to 9 (and only 9). Therefore there is only one solution
2: infinitely many solutions
Explanation: When an equation has infinitely many solutions, it means that any real number (aka <em>all real numbers</em>) would satisfy that equation. For example 2x = 2x. Any number you plug in for x would result in both sides being equal. So you know an equation has infinitely many solutions if both sides are the same
3: no solution
Explanation: 7 does not equal 4 so you can't solve this equation.
4: no solution
Explanation: 7 is not less than 7, that is impossible, so there is no solution.
5: one solution
Explanation: 8 <em>is</em> greater than or equal to -2, so this inequality is true, meaning it represents one solution
Answer:
51 and 42
Step-by-step explanation:
Use
x + y = 93
x - y = 9
Add those two equations together and you get 2x = 102
*y is not in the equation anymore because y + -y = 0*
Divide both sides by 2
x = 51
plug x into one of the equations; let's use x + y = 93
Then you get, 51 + y = 93
Subtract both sides by 51 and you get y = 42
Plug both in the other equation to make sure the numbers work.
51 + 42 = 93; true
51 - 42 = 9; true
Answer:
Its the third one I think.
