What is the answer to:<br> x + y = 4<br> Y= x+4<br> Using elimination
Ket [755]
X + y = 4
<span>y = x + 4

</span>x + (x + 4) = 4
y = x + 4

2x + 4 = 4 
y = x + 4

2x = 4 - 4 
y = x + 4 

x = 0
y = 0 + 4

x = 0 
y = 4

NEED HELP ASAP!! Solve for m

Angle B = 56.309932474020215

This is through using a trigonometry calculator I forgot how to set it up tbh.

Hope this helps ;)

For extra info Angle C = 33.690067525979785.

They add up to 90 which added with the right angle of 90 means the interior angles add to 180 meaning it is in fact correct because a triangle is always 180 inside.

KIM [24]
HI!
First of all, there are total 12 + 2 + 6 = 20 pairs of socks.
Probability of getting a pair of white socks the first time is 12/20.
Probability of getting a pair of gray socks without replacement, if first one was white, is 2/19
Therefore the probability t<span>hat she will take a white pair and gray pair</span> without replacement is 6/95 (I multiplied the two probabilities)
Let me know if there are any other questions!

The solution to the problem is as follows:

let


R = $619.15 periodic payment


i = 0.0676/12 the rate per month


n = 48 periods


S = the future value of an ordinary annuity


S = R[((1 + i)^n - 1)/i]


S = 619.15*[(1 + 0.0676/12)^48 - 1)/(0.0676/12)]


S = $34,015.99

I hope my answer has come to your help. God bless and have a nice day ahead!
