Answer:

The resulting equation is $2y-8 + 5y - 10 = 0$

Step-by-step explanation:

For the following system, use the second equation to make a substitution for x in the first equation.

$x + 5y - 10 = 0$ first equation

$x = 2y - 8$ second equation

Now substitute the second equation in first equation

Replace x with 2y-8 in first equation

$x + 5y - 10 = 0$

$2y-8 + 5y - 10 = 0$

The resulting equation is $2y-8 + 5y - 10 = 0$

fenix001 [56]

Answer:

the requirements are missing:

express the height of the rectangle in terms of w
express the area of the rectangle in terms of w

1) the height of the rectangle is:

w + h + h + w = 500 + w

2w + 2h = 500 + w

2h = 500 + w - 2w = 500 - w

h = (500 - w) / 2 = 250 - 0.5w

2) the are of the rectangle is:

w x h = w x (250 - 0.5w) = 250w - 0.5w²

Half-life of Po-210 is 140 days. If the initial mass of the sample is 5

Anna35 [415]

Answer:

$0.625kg$

Step-by-step explanation:

we are given half-life of PO-210 and the initial mass

we want to figure out the remaining mass after 420 days

in order to solve so we can consider the half-life formula given by

$\displaystyle f(t) = a {0.5}^{t/T}$

where:

f(t) is the remaining quantity of a substance after time t has elapsed.
a is the initial quantity of this substance.
T is the half-life

since it halves every 140 days our T is 140 and t is 420. as the initial mass of the sample is 5 our a is 5

thus substitute:

$\displaystyle f(420)=5\cdot{0.5}^{420/140}$

reduce fraction:

$\displaystyle f(420)=5\cdot{0.5}^{3}$

By using calculator we acquire:

$\displaystyle f(420)=0.625$

hence, the remaining sample after 420 days is 0.625 kg
