X = 1st number
y = 2nd number
x + y = 200
x : y = 4 : 6
ok! let's substitute numbers!
4 * 10 : 6 * 10
40 : 60
40 + 60 = 200
100 ≠ 200
Too small!
That is exactly two times smaller than 200 so let's try 2 times greater than multiplying by 10
4 * 20 : 6 * 20
80 : 120
80 + 120 = 200
200 = 200
Now it says to find the larger number. Which is y.
x :y = 4 : 6 = 80 : 120
so, y is 120
y = 120
Answer : y = 120. The larger number is 120.
Answer: Mike offer is the best.
Step-by-step explanation:
Assuming he work for 30hrs per week in a month he gets
30hrs x 10 = $300 x 4 = $1200
If Mark work 30hrs per week he gets
30hrs x $8 = $240 x 4 = $960 + Bonus $100 = $1,060
Therefore, Mike makes more money.
Answer:
Subtract: 5 - 9i = 5-9i
Add: the result of step No. 1 + (-4) = (5-9i) + (-4) = (5-4) + (-9i) = 1-9i
Add: the result of step No. 2 + 7i = (1-9i) + 7i = 1 + (-9+7)i = 1-2i
Subtract: 1 - 2i = 1-2i
Subtract: the result of step No. 1 - 4 = (1-2i) - 4 = (1-4) + (-2i) = -3-2i
Add: the result of step No. 2 + 7i = (-3-2i) + 7i = -3 + (-2+7)i = -3+5i
Step-by-step explanation:
Correct me if I'm wrong pls and ty :).
Hope this helps.
