How to solve 4/7y-2 = 3/7 + 3/14

lisabon 2012 [21]

Solution

1) Simplify $\frac{4}{7y}$ <span> to </span> $\frac{4y}{7}$
$\frac{4y}{7}$ <span>−2= </span> $\frac{3}{7}$ + $\frac{3}{14}$

2) Simplify $\frac{3}{7}$ + $\frac{3}{14}$ <span>to <span>914</span>
</span> $\frac{4y}{7}$ <span>−2= </span> $\frac{9}{14}$

3) <span>Add 2 to both sides
</span> $\frac{4y}{7}$ = $\frac{9}{14}$ <span>+2
</span>
4) Simplify $\frac{9}{14
}$ <span><span>+2</span> to </span> $\frac{37}{14}$
$\frac{4y}{7}$ = $\frac{37}{14}$

5) <span>Multiply both sides by 7
</span><span>4y= </span> $\frac{37}{14}$ <span>×7
</span>
6) Simplify $\frac{37}{14}$ <span><span>×7</span> to </span> $\frac{259}{14}$
$\frac{4y}{7}$ = $\frac{259}{14}$

7) Simplify $\frac{259}{14}$ <span> to </span> $\frac{37}{2}$
$\frac{4y}{7}$ = $\frac{37}{2}$

8) <span>Divide both sides by 4
</span>y= $\frac{37}{2}$ <span>×4
</span>
9) <span>Simplify <span>2×4</span> to 8
</span><span>y=</span> $\frac{37}{8}$
<span><span>
Hope this helps

Solve the proportion<br>16/6 = 3s/9

iris [78.8K]

Answer:

8

Step-by-step explanation:

So you can start by simplifying each fraction:

16/6 divide by 2/2 = 8/3

3s/9 divided by 3/3 = s/3

Then, since 8/3 = s/3 you just have s = 8.

A number, y, is equal to twice the sum of a smaller number and 3. The larger number is also equal to 5 more than 3 times the sma

Nata [24]

Answer:

The equations represent the situation is $y=2x+6$ and $y=5+3x$ .

Step-by-step explanation:

Consider the provided information.

First convert the statement into mathematical representation.

Consider the smaller number is <em>x</em> and the larger number is <em>y</em>.

<em>y</em>, is equal to twice the sum of a smaller number and 3.

This information can be written as: $y=2(x+3)$

Which can be further solve as:

$y=2x+6$

The larger number is also equal to 5 more than 3 times the smaller number.

This information can be written as: $y=5+3x$

Thus, the equations represent the situation is $y=2x+6$ and $y=5+3x$ .

Which can be further solve as:

$2x+6=5+3x$

$x=1$

Now, substitute the value of <em>x</em> in $y=5+3x$ .

$y=5+3$

$y=8$

Line t has an equation of y = -8x + 7. Line u includes the point (-1, 7) and is parallel to line

umka2103 [35]

Answer:

y = -8x - 1

Step-by-step explanation:

y = mx + b

7 = -8 (-1) + b Substitute in points for x and y. Substitute -8 for m (parallel)

7 = 8 + b

-1 = b
