Answer:
Cost of Dinner = 50t + 7c + 475
Step-by-step explanation:
"t" represents tables and they cost $50 each, so the algebraic expression would be "50t" ($50 times the number of tables).
Same applies to chairs; "7c" ($7 times the number of chairs).
The $475 represents the other costs added to the total.
So the expression to represent this problem would be at the total cost of the charity dinner is 50t (50 dollars per table) plus 7c (7 dollars per chair) and $475 for other costs.
Hey there, Bulgogi!
The correct answer will be the first one since [I'm assuming] you know that to calculate the percentage of something, it's the amount of that something divided by the total amount but since only 30 students voted [12+18] multiplied by 100.
So, we are calculating the percentage on votes and 12 students voted for Candidate A so our Numerator will be 12 and our Denominator will be the total amount of student who voted, so 30 [or 12+18]
Once put into a fraction, we will get
which would be equals to 2/5 or 0.4. Now we multiply by 100 and we get a total of 40% for Candidate A.
Thank you for using Brainly.
See you soon!
The relationship between the 3s are that the 3 in the hundreds place has the value of 300 while the 3 in the tens place has the value of 30. They have a quotient of 10. This means they are 10 times apart.
You can put 10 in the equation:
-10^2 -3*10 = -100 -30 = -130
