Okay so I would say d because
Step-by-step explanation:
because they all equal less than 1/4
Answer:
x=20% discount
y=$5 discount
Step-by-step explanation:
let
x= % of discount
y= amount of discount
Price of t shirt in store S=20 - 20x
Price of t shirt in store T= 20 -y
Rose spends $63 for three T-shirts from store S and one from Store T
Store S=20-20x
Store T=20-y
3 shirts from store S=3(20-20x)
1 from Store T=20-y
3(20-20x) + (20-y)=63
60 - 60x + 20-y=63
-60x - y= -17 (1)
Manny spends $140 on five T-shirts from store S and four from Store T
5(20-20x)+4(20-y)=140
100-100x+80-4y=140
-100x - 4y= -40 (2)
Solve eq 1 and 2
-60x - y= -17
-100x - 4y= -40
Multiply (1) by -4
-4(-60x-y)= -17*-4
240x+4y=68 (3)
-100x-4y=-40 (2)
Subtract (2) from (3)
140x=28
x=28/140
x= 0.2
substitute the value of x in (1)
-60x - y= -17
-60(0.2)-y=-17
-12-y=-17
-y=-17+12
-y=-5
Divide both sides by -1
-y/-1=-5/-1
y=5
Therefore,
x=0.2=20% discount
y=$5
1.) y=-M+s
2.) Y=2g+n
Hope this helped :)
The sum of the three angles of a triangle is always 180 degrees. If the triangle is right, which means one of the angles measures 90 degrees, the other two angles should add up to 90 degrees. With this condition and the given above, x + 15 + 2x = 90. Solving for x in the equation gives x = 25. Substituting x to the given expression for the acute angles gives the measurements of 40 and 50 degrees. Thus, the smallest angle of the triangle is <em>40 degrees</em>.
The answer is B because e is 2.17
