The answer is $162 you take the prices of what she bought and add them together which is $73+$38+$64=$180
then you subtract the $180 from $342 which is $342-$180=$162
so the answer is $162
Answer:
Y =3x/2 is the equation of the line.
Slope is 3/2
Y intercept is zero
Subtract 5y - 8 from 2y + 8
To subtract two numbers, we can do it like this:
10 - 4 = 10 + (-4)
That is, add the first number with the second number with its sign changed. For simple numbers, it does not make much difference, but for algebraic expressions, it can help a lot.
To subtract both binomials, we write the first plus the second with changed signs:
2y + 8
-5y + 8
---------------
-3y + 16
The result of the subtraction is -3y+16
Answer:
No element is common to all the sets
AnBnc = { }
Step-by-step explanation:
If A= {x: xis a factor of 72}
A = {2, 3, 4, 6, 8, 9, 12, 18, 36, 72}
If B= {x: 72x+3<2x-3).
72x+3 <2x-3
72x - 2x < -3-3
70x < -6
x < -6/70
x < -3/35
x< -0.0857
If
C= {x:x<20}
C = {-∞, 19}
The intersection of the sets AnBnc = {} i.e an empty set
Note that intersection means all the elements common to the three sets
Based on the information given, the inequality of the amount of sales that she must have to reach her goal would be :
0.04 s + 200 ≥ 450
