Mg+rg=2H, solve for g

Mathematics
1 answer:
Simora [160]3 years ago
4 0

Answer:

g=\frac{2\,H}{m+r}

Step-by-step explanation:

Starting with :

m g + r g = 2 H

extract "g" as a common factor on the left of the equal sign:

g (m + r) = 2 H

Now, in order to solve for "g" , divide both sides of the equal sign by the binomial (m + r):

g = (2 H )/(m + r)

g=\frac{2\,H}{m+r}

The Reeds are moving across the country. Mr. Reed leaves 4.5 hours before Mrs. Reed. If he averages 40mph and she averages 60mph
Diano4ka-milaya [45]

Answer:

Mr. Reed DATA:

rate = 40 mph ; time = x hrs ; distance = 40x miles

-----

Mrs. Reed DATA:

rate = 60 mph ; time = x - 3.5 hrs ; distance = 60x - 210 miles

Equation:

40x = 60x -210

-20x = -210

x = 10.5 hrs

x-3.5 = 7 hrs (Mr. Reed's time)

The denominator of a fraction is four more than three times the numerator. If both numerator and denominator are increased by fo
Oksanka [162]

Let the numerator = x. Then,

The fraction is x/(3x+4).

If both the numerator and denominator are increased by 4, the fraction will be (x+4)/(3x+8), which, according to the question is equal to 9/25. So,

(x+4)/(3x+8) = 9/25

25(x+4) = 9(3x+8)

25x + 100 = 27x + 72

2x = 28

x = 14

Thus, the numerator is 14 and the denominator is (3*14 + 4), which is equal to 46. So the fraction is 14/46.

Given the function f(x) = –0.5|2x + 2| + 1, for what values of x is f(x) = 6? x = 6, x = –5 x = 5, x = –5 x = 7, x = –6 no solut
allsm [11]

Answer:

Step-by-step explanation:

This is our absolute function for which we are tasked with finding the values of x that make the whole thing equal 6:

-.5 | 2x + 2 | + 1 = 6. Subtracting 1 from both sides gives us

-.5 | 2x + 2 | = 5. Dividing both sides by -.5 gives us

| 2x + 2 | = -10.

Because absolute value is in fact a distance measure, and one of the 2 things in math that will NEVER be negative is distance, there is no solution to this equation.

What is n? Stick around for more points
amm1812

N is a variable in algebra. Variables are letters that represent unknown numbers. Variables can be any letter of the alphabet.

Here's how to use n in an algebraic equation:

5 + n = 12

To find what N represents, let it be the only thing on the left side of the variable:

5 -5 + n = 12 - 5

n = 7
