Answer:
x = 1, y = 10
Step-by-step explanation:
y = -5x + 15 --- Equation 1
2x + y = 12 --- Equation 2
Substitute y = -5x + 15 into Equation 2:
2x + y = 12
2x - 5x + 15 = 12
Evaluate like terms.
15 - 3x = 12
Isolate -3x.
-3x = 12 - 15
Evaluate like terms.
-3x = -3
Find x.
x = -3 ÷ -3
x = 1
Substitute x = 1 into Equation 2:
2x + y = 12
2(1) + y = 12
2 + y = 12
Isolate y.
y = 12 - 2
y = 10
Answer & Step-by-step explanation:
The diameter of the circle is 8 m and the radius of the circle is 4 units. So, now we have to plug in the numbers so we can find the circumference and the area of the circle.
So, the circumference of the circle is 25.12 m.
So, the area of the circle is 50.24 units².

Answer:
12%
Step-by-step explanation:
Interés simple = Principal × Tasa × Tiempo
Tasa = Interés simple / Principal × Tiempo
Principal = 1700 soles
Tiempo = 1 año y 3 meses
12 meses = 1 año
3 meses = 3/12 = 1/4 = 0.25
Tiempo = 1.25 años
Tasa = 255 /1700 × 1.25
= 0.12
= 0.12 × 100
= 12%
Your sum is 4 times 10, or 40. We want to end up with 40. Subtract 8 because you added 8 before to work backwards. You get 32. Divide by 16 because the opposite of multiplication is division. You would get 2.
