At a concession stand, three hotdogs and two hamburgers cost 8.50, two hotdogs and three hamburgers cost 9.00. What is the cost

of one hamburger and one hotdog?
So far I have:
x=hotdog
y-hamburger
3x+2y=8.50
2x+3y=9.00
For the life of me I cannot remember any of the steps past that. Any help would be awesome.

You're on the right track. After you get both equations you need to cancel one of the variables. In this situation, it doesn't matter which variable you cancel out.

hi hun!

From what I understand, ill explain to the best of my knowledge so u understand!

First. off they asked for "proportionality" basically asking for the rate it's growing at or weeks its taking.

I see that:

Flower 1: 6 inches

Flower 2: 10 inches

Flower 3: 14 inches

The proportionality which these flowers are growing at is 4 inches every two weeks.

And I also see:

Week 3

Week 5

Week 7

When u look closer u can see that the weeks are divisible by the inches for each of the flowers and each answer u get is 2!

And also just by looking at the weeks which are 2 weeks separate if u count them.

Week 3 would be:

6/3=2

Week 5 would be:

10/5=2

Week 7 would be:

14/7=2

so the proportionality is 2! c:

How can you know if this equation is true? 1/2 + 3/8 = 4/10 = 2/5
romanna [79]

Answer:

<h2>2. Because 25<12, this equation can not be true.</h2>

Step-by-step explanation:

I just solved the equation and 1/2 + 3/8 = 7/8 or 87.5%.

4/10 equals 40%.

Since these two do not sync up, the equation must be false and 2 is the only answer saying the equation is false.

I'm always happy to help :)

Kipish [7]
Well, the first 16 were about 16*75=$1200 extra. The last 8 were $720 lost. Thus, the total profit is $480. He bought them with $7200, which means the profit is around 6.67%.

WILL GIVE BRAINLIEST!<br> Given that ℓ1 ∥ ℓ2 and y = 20°, find x.<br> x = <br> °
BabaBlast [244]
X will equal 40.

EXPLANATION: since they’re parallel and these are opposite angles, add them together to equal 180.
x+(20)+3x=180.
add common variables.
4x+20=180
subtract 29 from both sides
4x=160
divide each side by 4 so isolate x
x=40
