Answer:
x=1, y=6. (1, 6).
Step-by-step explanation:
-8x+4y=16
y=5x+1
----------------
-8x+4(5x+1)=16
-8x+20x+4=16
12x+4=16
12x=16-4
12x=12
x=12/12
x=1
y=5(1)+1=5+1=6
'12' and '48' (choices 'A' and 'D') will both work as common denominators.
The least one is '12' .
Since 4 is a factor of 12, any multiple of 12 is also a multiple of 4 , and can
serve as a common denominator. The smallest multiple of 12 is 12 itself.
Answer:
7
Step-by-step explanation:
im pretty sure at least. since x is on a midpoint, it'd half of 14.
Answer: b. four fifths plus two fourths
Step-by-step explanation: Change the fractions to their equivalents in 20ths-- like finding the common denominator.
Divide the original denominator into 20, then multiply the result by the original numerator to get the new numerator.
4/5 <em>20/5 = 4 4×4 = 16 so 4/5 is equivalent to 16/20</em>
2/4 <em>20/4 = 5 5×2 = 10 so 2/4 is equivalent to 10/20 </em>
Add: 16/20 + 10/20 = 26/20
