Answer: heres a sinplfied experesion 63xj
Step-by-step explanation:
The sum of all angles is 180 degrees. Which means.
![2y+y+10+50=180](https://tex.z-dn.net/?f=%3C%2Fp%3E%3Cp%3E2y%2By%2B10%2B50%3D180%20%3C%2Fp%3E%3Cp%3E)
Now just solve for y.
![3y+60=180 \\3y=120 \\y=\boxed{40}](https://tex.z-dn.net/?f=%3C%2Fp%3E%3Cp%3E3y%2B60%3D180%20%5C%5C%3C%2Fp%3E%3Cp%3E3y%3D120%20%5C%5C%3C%2Fp%3E%3Cp%3Ey%3D%5Cboxed%7B40%7D%3C%2Fp%3E%3Cp%3E)
The value of y is 40 therefore option B.
Hope this helps.

Answer:
3+2 = 22 +30= 59 1/2
(x + c)2 = d or (x – c)2 = d. = (c * d)(x) = 4x^3 + 18x^2 - 10x
X=1+2

Answer:
$6.22
Step-by-step explanation:
Given;
Total number of coins N = 50
Number of pennies p = 14% of N = 0.14 × 50 = 7
Number of dimes d = 32% of N = 0.32×50 = 16
Number of nickels n = 4 + number of pennies = 4+p
n = 4+7 = 11
Number of quarters q;
N = p+d+n+q
q = N - (p+d+n)
q = 50-(7+16+11)
q = 16
1 Penny = 1 cent = $0.01
1 Nickel = 5 cent = $0.05
1 dime = 10 cents = $0.10
1 quarter = 25 cents = $0.25
Total amount in the bag is;
C = 0.01p + 0.05n + 0.10d +0.25q
Substituting the values;
C = 0.01(7) + 0.05(11) + 0.10(16) + 0.25(16)
C = $6.22
The bag contains $6.22
