Answer:
The expression for the cost of soda is 100 × 
cents
Step-by-step explanation:
Given as :
The quantity of hot dogs sold by vendor = h
The quantity of sodas sold by vendor = s
The total cost of hot dogs and soda = $ d
Let The price of hot dogs = $ x
And The price of soda = $ y
Now, According to question
The price of hot dogs is twice as much as soda
so, $ x = 2 × $ y
I.e x = 2 y
and $ x h + $ y s = $ d
Or , 2 × $ y h + $ y s = $ d
Or, y =
∵ 1 dollar = 100 cents
So, the price of = 100 × cents
Hence The expression for the cost of soda is 100 × cents Answer
Answer:
15
Step-by-step explanation:
A=1/2(3)(3.5+6.5)
A=1.5(10)
A=15
(0+4) = 1(5-0)
point slope form
We know that the angles of a triangle sum to 180°. For ΔABC, this means we have:
(4x-10)+(5x+10)+(7x+20)=180
Combining like terms,
16x+20=180
Subtracting 20 from both sides:
16x=160
Dividing both sides by 16:
x=10
This means ∠A=4*10-10=40-10=30°; ∠B=5*10+10=50+10=60°; and ∠C=7*10+20=70+20=90.
For ΔA'B'C', we have
(2x+10)+(8x-20)+(10x-10)=180
Combining like terms,
20x-20=180
Adding 20 to both sides:
20x=200
Dividing both sides by 20:
x=10
This gives us ∠A'=2*10+10=20+10=30°; ∠B'=8*10-20=80-20=60°; and ∠C'=10*10-10=100-10=90°.
Since the angle are all congruent, ΔABC~ΔA'B'C' by AAA.
