Answer:
1 over 8
Step-by-step explanation:
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

D.There the exact same value and we would divide by 100 to go from percentage to decimal and multiply by 100 to go to decimal to percentage Sign.
Step-by-step explanation:
Answer:
(5, -1)
Step-by-step explanation:
Equation 1: 3x + y = 14
Equation 2: 2x - 2y = 12
Rewrite equation 1 to make y the subject:
⇒ y = 14 - 3x
Substitute this into equation 2 and solve for x:
⇒ 2x - 2(14 - 3x) = 12
⇒ 2x - 28 + 6x = 12
⇒ 8x - 28 = 12
⇒ 8x = 40
⇒ x = 5
Substitute found value for x into either equation and solve for y:
using equation 1:
⇒ 3(5) + y = 14
⇒ 15 + y = 14
⇒ y = -1
Therefore, the solution to the system is (5, -1)
