Step-by-step explanation:

first of all, you could use a calculator and see and compare.

but let's look at this logically :

what fully squared numbers are closest to 42 ?

there is 36 (6²) below, and 49 (7²) above.

so, the solution must be between 6 and 7.

now is 6, 6.5 or 7 closest to the real solution ?

the difference of 6² or 36 to 42 is 6, and the difference of 7² or 49 to 42 is 7.

42 is more or less in the middle.

that means that also the square root will be relatively close to the middle between 6 and 7.

so, 6.5 is the answer.

Factor out the coefficient of the variable 5/6s+2/3
DochEvi [55]
Okay. so I'm gonna assume you know what factor out means--were gonna take out 5/6. what we need to know is, how does that affect our ending number 2/3? well, we're gonna have 5/6 times some stuff first off, right?

5/6 ( )

so what's in the parenthesis? well, if we distribute in our mind, S would just have to be by itself for it to work out. so we have

5/6 ( s )

but what about 2/3? well, if we're multiplying everything on the inside by 5/6, how can be get it to cancel and leave 2/3 alone? we could divide 2/3 by 5/6, right?

5/6 ( s + (2/3) / (5/6) )

now, when we distribute our 5/6, we'll have just 2/3 at the end. now let's simplify that end term so it looks a little better. if we divide by a fracion, that's the same as multiplying by the flipped version, so let's do that.

2/3 / 5/6 = 2/3 × 6/5 = 2 (6) / 5 (3) = 12/15

we can reduce 12/15 by dividing the top and bottom by three.

= 4/5

so our final answer would be:

5/6 [S + 4/5] you can redistribute to make sure it matches. Anyway, hope that helps!

The sum of two numbers is 48 and the difference is 20. what are the number?​
rosijanka [135]

Answer:

x = 34; y = 14

Step-by-step explanation:

Step 1: Make the equations

x + y = 48

x - y = 20

Step 2: Solve the equations

x + y = 48

x - y = 20

2x = 68

x = 34

34 + y = 48

y = 14
