Solve The Linear Equation for the stated variable.

larisa [96]

Answer:

$m=\frac{g}{4c-3}$

Step-by-step explanation:

we have

$g=4cm-3m$

Solve for m

That means-----> isolate the variable m

Factor the variable m in the equation

$g=m[4c-3]$

Divide by (4c-3) both sides

$\frac{g}{4c-3}=m$

Rewrite

$m=\frac{g}{4c-3}$

A man invest 5,200,part at 4% and the balance at 3%. If his total income for the two investments is $194,how much money did he i

Fed [463]

Let the amount invested at 4% be = x

Let the amount invested at 3% be = y

Given is:

$x+y=5200$ or $x=5200-y$ .... (1)

As, total income for the two investments is $194, so equation is:

$0.04x+0.03y=194$ ....(2)

Putting value of x from (1) in (2)

$0.04(5200-y)+0.03y=194$

$208-0.04y+0.03y=194$

$0.01y=14$

$y=1400$

And x=5200-y

$x=5200-1400=3800$

Hence, money invested at 4% is $3800 and money invested at 3% is $1400

A grid shows the positions of a subway stop and your house. The subway stop is located at (–9, 7) and your house is located at (

miv72 [106K]

For this case, the first thing you should do is use the distance between points formula.
We have then:
d = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)
Substituting we have:
d = root ((9 - (- 9)) ^ 2 + (-2-7) ^ 2)
d = 20.1246118
Rounding off we have:
d = 20 units
Answer:
The distance, to the nearest unit, between your house and the subway stop is:
B. 20
