1. 2 3/4 = 11/4(2 * 4 + 3)
2. 1 1/4 = 5/4(1 * 4 + 1)
11/4 * 5/4 = 55/16 OR 3 7/16 if simplified.
Answer:
"Dominic lived in Spain for 13 months and Columbia for 7 months."
Step-by-step explanation:
let months stayed in spain be "s" and months stayed in columbia be "c"
We can write 2 equations.
Since, lived in Spain and Columbia for a total of 20 months, we can write:
s + c = 20
Also, since 120 words per month in Spain and 150 words per month in Columbia for a total of 2610 new words, we can write:
120s + 150c=2610
Solving first for s:
s = 20 - c
Putting in 2nd and solving:
120(20 - c) + 150c = 2610
2400 - 120c + 150c = 2610
30c = 210
c = 7
Now,
s = 20 - c = 20 - 7 = 13
So
"Dominic lived in Spain for 13 months and Columbia for 7 months."

Answer:
B. Real numbers
Step-by-step explanation:
Real numbers are all numbers, rational and irrational, that could be found on a plane. This includes all positive and negative numbers, and all decimals. So, this only excludes imaginary numbers. The rest of the options exclude irrational numbers and more.
Recall that the interior angles of a quadrilateral add up to 360 degrees.
1) Let x be the measure of the missing angle, then we can set the following equation:
Solving for x we get:
2) Let y be the measure of the missing angle, then we can set the following equation:
Solving for y we get:
Answer:
1) 100 degrees.
2) 58 degrees.
