Answer:
x=5
Step-by-step explanation:
since it’s isosceles trapezoid, diagonals are equal.
x+10=2x+5
x=5
Answer:
Step-by-step explanation:
perpendicular is 90 degrees or inverse slope of that point
y = -1/4x -1
so the inverse slope of -1/4 is 4
now the other equation is
y = 4x - 1
So the two equations are
y = -1/4x -1
y = 4x - 1
Answer:
On sale at a deficit of -20% from the original price is saying that the item is at 80% of its original value.
Converting percentages using decimals is a very easy way to fine original values.
So:
$76.80 = 80% of the original value
convert the 80% into a decimal = 0.80
The maths:
$76.80 ÷ 0.8 = $96.00
$96.00 = the original value.
The amount of money that Hudson will need to save each week is $106.25.
<h3>How to calculate the value?</h3>
From the information, they determine that the trip will cost $3,200. Mr. and Mrs. Hudson have already set aside $1,500 for the trip.
Let the amount saved each week be represented as w.
Based on the information given, this will be illustrated as:
1500 + 16w = 3200
Collect like terms
16w = 3200 - 1500
16w = 1700
Divide
w = 1700 / 16
w = 106.25
The amount is $106.25.

Keep subtracting 1/5 from 3
3 -(1/5)-(1/5)-(1/5)-(1/5)-(1/5)-(1/5)-(1/5)-(1/5)-(1/5)-(1/5)-(1/5)-(1/5)-(1/5)-(1/5)-(1/5) = 0
3 / (1/5) = 15
We subtracted (1/5) 15 times till we got to 0.
