Okey I help you
3x+5y=26
5*/2x-y=13
3x+5y=26
10x-5y=65
+------------------
13x= 91
x=7
3x+5y=26
3*7+5y=26
5y=5
y=1 ,,
Hope it helps :))
Answer:
In 1979 the amount of transistors in a chip was approximately 27865.
Step-by-step explanation:
Since the number of transistors in 1974 was 5000 per chip and it increases at a rate of 41% per year, the number of transistors in a chip per year can be modelled by the following expression:
chips(t) = 5000*(1.41)^(t - 1974)
Therefore in 1979, we have:
chips(1979) = 5000*(1.41)^(1979 - 1974)
chips(1979) = 5000*(1.41)^5
chips(1979) = 27865.4183
In 1979 the amount of transistors in a chip was approximately 27865.

Answer:
28.3 cm
Step-by-step explanation:
The formula to find the circumference is 2•π•radius. The diameter is 9 cm, so the radius is 9/2 = 4.5 cm. So, the circumference is:
2•4.5•3.14 = 28.26 ≈ 28.3 cm
Answer:
x^3 +8x^2 +11x -20
Step-by-step explanation:
(x+5) * (x^2+3x-4)
Multiply x * (x^2+3x-4) = x^3 + 3x^2 -4x
Multiply 5 * (x^2+3x-4) = 5x^2+ 15x -20
Add -----------------------------------
x^3 +8x^2 +11x -20
