Answer:
C
Step-by-step explanation:
x^2/12.25 + y^2/4 = 1
Answer: (x, y) = (2, 3)
This is the system of equations 2x - 3y = -5, 5x - 2y = 4. Multiply the first equation by 2 and the second equation by 3 to get 4x - 6y = -10, 15x - 6y = 12. Now we can use elimination: subtract the equations to get -11x = -22, so x = 2. 2x - 3y = 2(2) - 3y = 4 - 3y = -5, so 3y = 9 and y = 3. The solution is (2, 3).

Answer:
n=−5
Step-by-step explanation:
0.6(10n+25)=10+5n
Step 1: Simplify both sides of the equation.
0.6(10n+25)=10+5n
(0.6)(10n)+(0.6)(25)=10+5n(Distribute)
6n+15=10+5n
6n+15=5n+10
Step 2: Subtract 5n from both sides.
6n+15−5n=5n+10−5n
n+15=10
Step 3: Subtract 15 from both sides.
n+15−15=10−15
n=−5
Step-by-step explanation:
for a
- a+,38°=90°{ angle at circumference through center is 90°}
- a=90-38
- a=52°
for e
- e=38°{base angle of isosceles triangle r equal}
for d
- 38°+e+d=180°{sum of angle of triangle}
- d=180-76
- d=104°
for. c
- c+d=180°{straight angle}
- c=180-104°
- c=76°
for b
- a+b+c=180°{sum of angle of triangle}
- b=180-128
- b=52°
hope it helps.
