Answer: what you need to do is multiply 3 times 1 and add 2 to the sum that you get which would be 5/3 for the first one because you keep the same denominator! Just multiply the denominator the bottom number and add the numerator the top number to your sum that you got from multiplication! Do that for all of them and you should get an improver fraction!

Finding the reciprocal is easy just flip the numbers I’m in 6th grade I learn this already!
For example just flip 3/7 to 7/3
1. 40
2. 5
3. 2
4. 2 units per text message
Answer:
2 minutes
Step-by-step explanation:
You can make an equation to model the question.
y=60 initial starting value,
y=(750-720)x, plug in 60 for y,
60=30x, x = 2 minutes
Answer:
used Pythagorean theorem to figure this out
a² + b² = c²
BC ~ 11.5 mm
Step-by-step explanation:
Let h be hot dogs and s be sodas
h+s=221
h=s-59
s=s
s+s-59=221
2s-59=-221
2s=280
s=140
h=140-59=81
140+81=221
Answer: there were 81 hotdogs and 140 sodas sold
