Answer:
B for the first one , and C for the second
Step-by-step explanation:
for the first question DEG which is 60, and GEF which is 120, would equal to 180 degrees, which would be DEF because its a linear pair.
For the second question the are alternate exterior angles, so the are opposite of each other and on the outside.
Answer:
x = 4
Step-by-step explanation:
110ₓ = 40₅ --------- change all to base ten.
<u>the system called binary</u>
1x²+1x ¹+0x⁰ = 45¹+0*5⁰
x² + x + 0 = 20
x² + x – 20 = 0
solve x using Quadratic equation
-1 ± 
x = ------------------------------------
2 * 1
x = -5; x = 4
therefore, x = 4
3x - 6 = 2x + 6
3x = 2x + 6 + 6
3x = 2x + 12
3x - 2x = 12
x = 12
Answer:
B
Step-by-step explanation:
At the numerator we have to put 8, while at the denominator we have to put 26
8/26
now we can simplify the fraction by dividing both numerator and denominator by 2
(8:2)/(26:2)
4/13
