Because there is a square at the bottom of the figure, we can say that the angle is equal to 90 degrees (x+22). Thus, the equation would be
x+22 = 90
x = 68
The value of "x" is then equal to 68

Answer:
Yes
With an extra 3000CHF
Step-by-step explanation:
In year 2005, the exchange rate was 1$ = 1.15CHF
The student came in with $20,000.
The amount he had in CHF(swiss franc) = ?
$1 = 1.15C
$20,000 = x CHF
X = (20000 × 1.15) / 1
X = 23,000CHF
When he came to Zürich in 2005, he has 23,000 swiss franc.
But the exchange rates changed in 2006 to C1.30 against the dollar.
$1 = 1.30CHF
$20,000 = xCHF
X = 26,000CHF
In 2006, he would've had 26,000CHF.
The difference between what he would've had in 2006 against 2005 is
26,000CHF - 23,000CHF = 3000CHF
He would've had an extra 3000CHF if he came in the year 2006.
Answer:
3:4, 15:20, 60:80
Step-by-step explanation:
If a train is traveling 8 miles every 6 minutes then you find the ratio 6:8 to find the first answer you divide both numbers by two. To find the second number you multiply the 3:4 by five, and to find the third number you multiply the 3:4 by 20.
3:4
15:20
60:80
![\sf 5x+2y=21](https://tex.z-dn.net/?f=%5Csf%205x%2B2y%3D21)
![\sf -2x+6y=-34](https://tex.z-dn.net/?f=%5Csf%20-2x%2B6y%3D-34)
We could solve for 'x' in the 2nd equation and then plug that into the first equation for 'x' and solve for 'y':
![\sf -2x+6y=-34](https://tex.z-dn.net/?f=%5Csf%20-2x%2B6y%3D-34)
Subtract 6y to both sides:
![\sf -2x=-6y-34](https://tex.z-dn.net/?f=%5Csf%20-2x%3D-6y-34)
Divide -2 to both sides:
![\sf x=3y+17](https://tex.z-dn.net/?f=%5Csf%20x%3D3y%2B17)
Plug in 3y + 17 for 'x' in the first equation:
![\sf 5x+2y=21](https://tex.z-dn.net/?f=%5Csf%205x%2B2y%3D21)
![\sf 5(3y+17)+2y=21](https://tex.z-dn.net/?f=%5Csf%205%283y%2B17%29%2B2y%3D21)
Distribute 5:
![\sf 15y+85+2y=21](https://tex.z-dn.net/?f=%5Csf%2015y%2B85%2B2y%3D21)
Combine like terms:
![\sf 17y+85=21](https://tex.z-dn.net/?f=%5Csf%2017y%2B85%3D21)
Subtract 85 to both sides:
![\sf 17y=-64](https://tex.z-dn.net/?f=%5Csf%2017y%3D-64)
Divide 17 to both sides:
![\boxed{\sf y\approx -3.8}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Csf%20y%5Capprox%20-3.8%7D)
This is the y-coordinate of the solution.
