9a+6s =cost
substitute 3 adults and 5 students
9(3) +6(5) = cost
multiply
27+30=cost
add
57=cost
Total cost is $57
Hi there!
To solve your answer, since we know a = 7, we can easily solve your equation.
But before we go onto that, I want to show you a tip or two about solving equations with variables next to numbers.
When you have a number, and a variable attached to it, it means to multiply.
Now, to make this equation look a little easier, lets rewrite it.
9 × 7 - 5 × 7 = ___
According to PEMDAS, we won't go straight from left-to-right when solving here. We'll skip around a little.
9 × 7 = 63.
5 × 7 = 35.
Now, since we've multiplied the two numbers, its time to subtract them.
63 - 35 = 28. Sooooo........
9 × 7 - 5 × 7 = 28
Hope this helps!
Message me if you need anything else, I'd be happy to help you out! :D
Answer:
Do not use that's to solve the hypotenuse of a triangle.
The difference is 31 cm³
Step-by-step explanation:
To solve the volume a cube it's a³
5.7³ = 185.193
I'm assuming to round to the nearest whole number so the difference would be
216 - 185 = 31
