Lets check...
42/56 = 56/64
cross multiply
(56)(56) = (42)(64)
3136 = 2688...(incorrect)...these are not proportional
proportions are nothing but equivalent fractions
42/56 = 3/4
56/64 = 7/8
as u can see, they are not equivalent fractions...so they are not proportional
Answer: 7/12
the LCM IS<u> 7/12 </u>
THE LEAST COMMON MULTIPLE OR LCM OF TWO OR MORE NON-ZERO NUMBERS IS THE SMALLEST WHOLE NUMBER THAT IS DIVIDED BY EACH OF THOSE NUMBERS. IN OTHER TERMS,THE LCM IS THE SMALLEST NUMBER THAT ALL OF THE NUMBERS DIVIDE INTO EVENLY
Answer:
Step-by-step explanation:
So first you got to simlipy both sides of the equation.Like this:
10x-3x+2=6x+6
7x+2=6x+6
Then you have to move the variables to one side and the other nums to the other side:
7x-6x = 6 -2
Then you have to simplify.
x = 4
Hoped it helped!
Answer:
$ 1.2 and $ 0.7
Step-by-step explanation:
In this case we can solve it by means of a 2x2 system of equations, like this:
Let x is the value of clif bars
let y is the value of an apple
Thus:
4 * x + 2 * y = 6.2
5 * x + 3 * y = 8.1 => x = (8.1 - 3 * y) / 5
replacing, we are left with:
4 * ((8.1 - 3 * y) / 5) + 2 * y = 6.2
6.48 - 2.4 * y + 2 * y = 6.2
2.4 * y - 2 * y = 6.48 - 6.2
0.4 * y = 0.28
y = 0.28 / 0.4
y = 0.7
Now to calculate x:
x = (8.1 - 3 * 0.7) / 5
x = 1.2
So the value of clif bars is $ 1.2 and the value of an apple is $ 0.7
