Answer:
B, C, and D
Step-by-step explanation:
They all have lower values than 2.1
y: original price (in dollars)
0.12y: amount of discount (in dollars)
sale price: y - 0.12y = 0.88y
sales tax on this sale price: (0.06)(0.88y)
final cost: 0.88y + (0.06)(0.88y) = 0.88y(1+0.06) = 0.9328y
Hey there! :)
If the width is 10 ft and the farmer wants the length to be 3x the width:
Length = 3w
W = 10
10 × 3 = 30
The width is 10 ft and the length is 30 ft.
Remember: You have to find the perimeter
Perimeter = 2l + 2w
l = 30
30 × 2 = 60
w = 10
10 × 2 = 20
60 + 20 = 80
Your answer is 80 ft of fencing
Hope this helps :)
Answer:
Step-by-step explanation:
-9x - 15y = -6
9x + 11y = 14
-4y = 8
y = -2
3x - 10 = 2
3x = 12
x = 4
(4, -2)
Answer:
70 and 110
Step-by-step explanation:
The two angles add to 180 degrees since they form a straight line
2x+10 +3x+20 =180
5x+30 = 180
Subtract 30 from each side
5x+30-30 =180-30
5x = 150
Divide by 5
5x/5 =180/5
x = 30
The left angle is 2x+10 = 2*30+10 = 60+10 =70
The right angle is 3x+20 = 3*30 +20 = 90+20 = 110
