Kx-bf=fy/m solve for y

2 answers:

8 0

So you need to isolate y:
First you multiply m on both sides:
m(Kx - bf) = fy
Then, you divide f on both sides:
$\frac{(m(Kx-bf))}{f}$ = y

Multiply both sides by (m) and you get (mkx-mbf=fy)

Then divide both sides by (f) and you get ((mkx-mbf)/(f)) = y

A recipe uses 5 cups of flour for every 2 cups of sugar how much flour is needed for 1 cup of sugar

Maslowich

There are a couple of ways to look at this.

1) Set up a ratio: 2 cups sugar to 5 cups flour = 5 cups sugar to x cups flour

2/5 = 5/x

cross multiply

2x = 25

x = 12 1/2 cups flour

2) Look at the factor by which the cups of sugar was increased and increase

the cups of flour by the same factor.

2x = 5

x = 2.5

The sugar was increased by a factor of 2.5 so increase flour by same factor.

5(2.5) = 12 1/2 cups flour

horrorfan [7]

Answer:

$13x + 10x + 21 = 90 \\ 23x + 21 = 90 \\ 23x = 69 \\ x = 3$

The measure of angle DEH

$13(3) = 39 \: degrees$

commercial angle FEH

$10(3) + 21 = \\ 30 + 21 = 51 \: degrees$

Gary bought 32 lb of potting soil this week this amount is 6 lb more than twice the amount of potting soil he bought last week a

lys-0071 [83]

Let the amount of potting soil bought last week be $x$

We know that this week's amount is 32 lb
We also know that this week's amount is double the amount of last week's plus 6 lb

So we write the equation:
$32 = 2x+6$

Solving this equation:
$32=2x+6$ ⇒ subtracting 6 from both sides
$32-6=2x+6-6$
$26=2x$ ⇒ Dividing both sides by 2
$\frac{26}{2}= \frac{2x}{2}$
$13=x$

The answer is: 13
