The weight of an object on the moon varies directly with its weight on the earth. If an object weighing 95 lbs on the moon weigh

Luda [366]

ANSWER

450lb

EXPLANATION

If the weight, m of an object on the moon varies directly as the weight of an object e, on the earth, then we can write the mathematical statement,.
$m \propto \: e$
We introduce the constant of proportionality to obtain,

$m = ke$

When, m=95, e=570,

This implies that,

$95 = 570k$
$k = \frac{95}{570}$

$k = \frac{1}{6}$

The equation now becomes,

$m = \frac{1}{6} e$

We want to find e, when m=2700,

$m = \frac{1}{6} \times 2700$

$m =450lb$

Find all solutions for 2y - 4x =2 y = 2x + 1 site:socratic.org

sladkih [1.3K]

Answer:

All real numbers would be the solution

Step-by-step explanation:

2y - 4x =2 and y = 2x + 1

We solve but placing the value of y into the first equation:

2(2x + 1) - 4x = 2

Next we distribute the 2 through the parenthesis:

4x + 2 - 4x = 2

Now we gather like terms:

2 = 2 ( note the 4x and - 4x cancel out)

Since 2 =2 this tells us that all real numbers would work.

Is it possible for an acute angle and obtuse angle to create complementary angles?

kenny6666 [7]

I’d say no because a complementary angle is 2 or more angles with a sum of 90 degrees [tip for differentiating supplementary and complementary angles: complementary (c) comes first in the alphabet (this is 90 degrees) and supplementary (s) comes later (this is 180 degrees. 180 comes later in counting] Anyway, an obtuse angle is more than 90 degrees which already can’t be a sum. (I’m not 100% sure but I hope this helps!)

Twice a number k plus 8 equals one-half times the quantity of four times a number k plus fourteen ?

belka [17]

Answer:

No solutions

Step-by-step explanation:

So putting that into an equation it equals

2k+8=(4k+14)÷2

Move the 2 to the other side.

2∙2k+8=4k+14

Simplify.

4k+8=4k+14

It doesn't make sense so No Solutions
