Answer: the commission that she earns for selling each suit is $13
the commission that she earns for selling each pair of shoes is $8
Step-by-step explanation:
Let x represent the commission that she earns for selling each suit.
Let y represent the commission that she earns for selling each pair of shoes.
One week, she earned $47 in commission for selling 3 suits and a pair of shoes. It means that
3x + y = 47 - - - - - - - - - - 1
The next week, she earned $107 in commission for selling 7 suits and 2 pairs of shoes. It means that
7x + 2y = 107 - - - - -- - - - -2
Multiplying equation 1 by 2 and equation 2 by 1, it becomes
6x + 2y = 94
7x + 2y = 107
-x = -13
x = 13
Substituting x = -13 ,into equation 1, it becomes
3×13 + y = 47
39 +y = 47
y = 47 - 39 =
y = 8
Answer:
The scores are between 50 and 90
Step-by-step explanation:
When we say middle 95%, we means that this value falls between 2 standard deviations of the mean i.e
μ ± 2σ
Hence,
mean of 70 and a standard deviation of 10
μ ± 2σ
μ - 2σ
70 - (2 × 10)
= 70 - 20
= 50
μ + 2σ
= 70 + (2 × 10)
= 70 + 20
= 90
Answer:
x=0
Step-by-step explanation:
Subtract 1 from both sides
2x+1-1<1-1
Simplify the arithmetic
2x<1-1
Simplify the arithmetic
2x<0
Isolate the X
X=0
Answer:
-2,5 since it is in the same quadrant of -6,4 which Is the gym
Think about it this way. Imagine a graph in your head. Left is negative. Right is positive. Up is positive and down is negative. Think of the numbers as rise over run. Vertical then horizontal. Because the gym is negative then positive you would need a number that is to the left then up.
Hope this helped:)
