I hope this helped to answer your question.
Have a great day! :)
Step-by-step explanation:
y = 6x-11
substitute y into 2x+3y=7
2x+3(6x-11)=7
2x + 18x-33 = 7
20 x = 7+33
x = 2
y?
y= 6(2)-11
y = 12-11 = 1
so, x = 2 and y = 1
18/230 = (approximately) 0.07826.
Multiply by 100 to change the decimal to a percent.
Answer:
x=1
Step-by-step explanation:
Convert decimals to fractions:
11/5x + 11/5 / 4= 1.1
Simplifies the fraction:
11x+11 / 20= 1.1
Remove denominator (then multiply by 20 on both sides):
11x+11=22
Move the x to the left:
11x= -11+22 → 11x=11
Simplify:
11x=11 → x=1
Answer:
8t^3-36t^2+54t-27
Step-by-step explanation:
(2t-3)^3
(2t-3)(2t-3)(2t-3)
Multiply the first two terms
(4t^2 -6t -6t+9)(2t-3)
Combine like terms
( 4t^2 -12t +9) ( 2t-3)
Multiply
2t*( 4t^2 -12t +9) -3 ( 4t^2 -12t +9)
Distribute
8t^3 -24t^2 +18t-12t^2 +36t-27
Combine like terms
8t^3-36t^2+54t-27
