Answer:

  f = d/(x+1)

Step-by-step explanation:

Factor out f, then divide by its coefficient.

  d=f+fx\\\\d=f(1+x)\\\\\dfrac{d}{1+x}=f\\\\\boxed{f=\dfrac{d}{x+1}}

_____

<em>Additional comment</em>

When writing this in plain text, parentheses are needed to perform the same grouping action that the fraction bar performs in a typeset expression:

  f = d/(x+1)

Solution q-2r=4<br> q+r=37
GenaCL600 [577]
Q-2r=4, therefore: q=4+2r.

Plug the value of q into q+r=37, so you get:

4+2r+r=37

3r=37-4=33

3r=33

Therefore: r=11.

q-2r=4, but r=11, so:

q-2(11)=4

q-22=4

Therefore q=26.

Check if the answer is correct using second equation:

q=4+2r=4+2(11)=4+22=26.

So: q=26 and r=11.

George and Carmen went on a bicycle trip. they took a bus to their starting point, and then biked the rest. They traveled 3oo ki
jeka94

Answer:

George and Carmen traveled 185 kilometers by bike and 115 kilometers by bus

Step-by-step explanation:

<u><em>The question is</em></u>

Find how many kilometers they traveled by bike

Let

x ---->  kilometers traveled by bike

y ---->  kilometers traveled by bus

we know that

They traveled 300 kilometers in total

so

x+y=300 ----> equation A

They biked 70 kilometers more than they were bus

so

x=y+70 ----> equation B

substitute equation B in equation A

(y+70)+y=300

solve for y

2y+70=300\\2y=300-70\\2y=230\\y=115

<em>Find the value of x</em>

x=115+70=185

therefore

George and Carmen traveled 185 kilometers by bike and 115 kilometers by bus

Find an equation of the plane. the plane through the point (4, 0, 1) and perpendicular to the line x = 3t, y = 3 − t, z = 7 + 9t
Bingel [31]
Position vector R = < 4,0,1>
(given point)

normal vector n = < 3,-1,9>

equation:
n(r-R) = 0

3(x-4) - y + 9(z-1) = 0
