Answer:
D. 23i.
Step-by-step explanation:
(26 + 16i) − (26 − 7i)
Using the distributive law this becomes:
26 + 16i - 26 + 7i
Adding like terms:
= 0 + 16i + 7i
= 23i (answer).
Answer: 10
Step-by-step explanation:
A. 38
Let X = seventh graders
6th graders are twice the number of 7th graders; therefore, 6th graders will be 2X.
The total number of students is 57.
2X + X = 57
3X = 57
X = 57 / 3
X = 19
IF X represents the 7th graders; there are 19 seventh graders present.
Since 6th graders are represented by 2X; Then, 2 * 19 = 38 is the number of 6th graders present.
Add both numbers to check: 19 + 38 = 57.
