if there are 14 people in a class given 5 boys, then there are 9 girls. The values needed are boys (5), girls (9), and total students (14). Ratio Girls : Boys is 9 : 5 and Ratio All Students : Girls is 14 : 9
Answer:
9:5
Step-by-step explanation:
if there are 14 people in a class given 5 boys, then there are 9 girls.
s^3 formula could be used to find the volume of. cube with side length equal to s.
y = 3x + 7
2x - 3y = 7 and -3x + y = 7..multiply Equation 2 by THREE and add to Equation 1
-9x + 3y = 21...........................watch the y's disappear
-7x........ = 28
x = -4
substitute -4 instead of x in either of the ORIGINAL equations
2x - 3y = 7
2(-4) - 3y = 7
-8 -3y = 7..........add 8 to both sides
-3y = 15
y = -5

b 1+2i
c 3
d 1−2i
Answer:
D. 1-2i is your answer.
Step-by-step explanation:
What you're doing is adding them together.
4 + -3 + -7i + 5i = 1-2i
D. 1-2i is your answer.
