<span>Multiply all terms by (x-3)(x-1) would be your first step.</span><span> </span><span>
</span><span>
</span>This gives you:
3(x - 1) = (x - 3) + 7
3x - 3 = x + 4

-x on both sides:
2x - 3 = 4

Add 3 to both sides:
2x = 7

Divide both sides by 2:
x = 7/2

If y varies directly as x, and y is 12 when x is 1.2, what is the constant of variation for this relation? A) 1 B) 10 C) 10.8 D)

\bf \begin{array}{cccccclllll}&\\&#10;\textit{something}&&\textit{varies directly to}&&\textit{something else}\\ \quad \\&\\&#10;\textit{something}&=&{{ \textit{some value}}}&\cdot &\textit{something else}\\ \quad \\&\\&#10;y&=&{{ k}}&\cdot&x&\\&#10;&\\&#10;&&  y={{ k }}x&\\&#10;\end{array}& \\\\\\&#10;\textit{we know that }&#10;\begin{cases}&#10;y=12\\&#10;x=1.2&#10;\end{cases}\implies y=kx\implies 12=k\cdot 1.2

solve for "k" to find "k", or the "constant of variation"

What is the slope of a line parallel to the line -3x+5y=-10
lapo4ka [179]

This looks familiar, right? Like slope-intercept.

y=mx+b, where m is the slope.

Let's right it like that.

5y=3x-10 (add 3x to both sides, since we want to isolate the y.)

Now divide by 5, since - again - we want to isolate the y.

y= 3/5x-10/5 >>>> y= 3/5x-2

I think the slope is 3/5.

If the line happens to be parallel, the slope is the same. If perpendicular, it is opposite reciprocal. So if it was perpendicular, the slope would be -5/3.

The perimeter is 10.3.  I think that's already in significant digits, but I'm not sure.  We just got finished learning that in chemistry and it confused me to death!

The longest side of a triangle is eight more units than the shortest side . The third side is three times the length of the shor
inysia [295]

Answer:

shortest side= x

longest side= x+8

other side= 3x

x+x+8+3x= 33

5x+8=33

5x= 25

x= 5

shortest side= x= 5

longest side= x+8= 5+8= 13

other side= 3x= 3(5)=15

Math im soooooooooooooo baaaaaaaaaaaadddddddddddddd
storchak [24]

Answer:

The correct answer is A, 73

Step-by-step explanation:

First we have to arrange the whole numbers in ascending order. i-e from smallest to largest. Showing it as follows:

53 54 59 62 64 65 66 68 70 71 75 78 79 79 83 83 86 90 91 94                

Now we would find the median by taking the middle number. But this series consists of even numbers. There are 20 numbers. So we will take the middle two numbers and find their average like follows:

71 + 75 = 146/2  = 73

The answer is 73
