Answer:
Nadia's commission per week is $770
Amount Nadia made in commission in 2011 is $40,040
Step-by-step explanation:
Commission made last week = 11% of $7,000
Therefore commission made last week = 0.11 × $7,000 = $770
Whereby Nadia averages the same aount each week, the amount Nadia would make in commission in 2011 is given by
Amount Nadia makes per week in commission = $7,000
Number of weeks in a year = 52 weeks. Therefore, amount Nadia makes in one year is given by
Amount in commission per week × 52 weeks
=$770 × 52 = $40,040
Amount Nadia made in 2011 = $40,040.
<span>The number is less than 190,000 and greater than 180,000
5,000 more than the number has 187 thousands
2000 less than the number has 4 hundreds
180, 000 <n> 190, 000</span>
180,000 + 2000 = n = 5000-187, 000
182,000 = n = 182, 000
Or,
<span>180, 000 <n> 190,000 </span>
<span>n + 5000= 187, 000 n
– 2000 = 180, 000</span>
<span>
n= 187, 000- 5000 n
= 180, 000 + 2000</span>
<span>
n= 182, 000 n=
182, 000</span>
9. 4- 2(8) = -12
55-40 = 15
so C is true
8. B
3 and 6 i dont know . seems : 4 . C & D are both correct
6 . All correct
Answer: Choice C) -11
-----------------------------------
Explanation:
The first equation given is y = 3 - 1/2x
In other words, y is the same as 3 - 1/2x.
We can replace y in the second equation with 3 - 1/2x
This is known as substitution (think of a substitute teacher who is a temporary replacement for your teacher)
Doing this leads to...
3x+4y = 1
3x+4*y = 1
3x+4*( y ) = 1
3x+4*( 3 - 1/2x ) = 1 <<--- y has been replaced with 3-1/2x
3x+4*(3) +4*(-1/2x) = 1
3x+12-2x = 1
3x-2x+12 = 1
x+12 = 1
x+12-12 = 1-12 <<-- subtracting 12 from both sides
x = -11
Which is why the answer is choice C) -11
