To answer this question we need to use subtraction.
we need to make the denominators the same.
In order to make them the same we need to find the least common multiple, of 8 and 5.
The least common multiple(the smallest shared value of the two numbers) is 40.
Next we divide our old denominator 5 by 40, which gives us 8, we multiply 8 by the numerator 2, which gives us 16. So now we have 16/20. We have to do the same to the other side. 8÷40 = 5. 5 x 3 = 15. Now we have 15/20.
Now we have a brand new equation, 16/40 - 15/40. The answer is 1/40.
In a fraction the answer is 1/40, so Karen rides her bike further.
In decimal form the answer is 0.025.
I hope this helps!
Answer:
x<-2
Step-by-step explanation:
12x>6x+12-15 (first distribute)
12x>6x-3 (simplify)
6x>-3 (put like terms on one side by subtraction)
x<-2 (divide and switch inequality sign since you divided by a negative)
2x+y=5
x+y=4
We need to solve 2x+y=5 for y
let's start by adding -2x to both sides
2x+y-2x=5-2x
y=-2x+5
Now substitute -2x+5 for y in x+y=4
x+y=4
x-2x+5=4
-x+5 =4
Add -5 to both sides so we can find the value for x
-x+5-5=4-5
-x=-1
We know that x can not stay with the negative sign so to eliminate that we need to divide both sides by -1
-x/-1= -1/-1
x=1
Now we have the value for x :)
We need to find the value for y by substitute 1 for x in y=-2x+5
y=-2x+5
y= (-2)(1)+5
y= -2+5
y= 3
Final answer : x=1 and y=3
(1,3)
I hope that's help :)
