What equation is equivalent to 2+3(2x+4)=13
Answer:
14+6x=13, or further 1+6x=0
Step-by-step explanation:
2+3(2x+4)=13,
Distribute the 3 into the parenthesis:
2+6x+12=13
Now combine like terms: 14+6x=13.
You can also write this as 1+6x=0 by subtracting 13 to the left, though it might not be necessary.
4. Emilio asks his classmates what month they were born. He finds that 15
out of 125 classmates were born in July. If there are 1,280 students in
Emilio's school, how many students can he expect to have birthdays in July
based on the experimental probability?
Ok
Answer:153
Step-by-step explanation:
From the question, we are informed that Emilio asks his classmates what month they were born and that he finds that 15 out of 125 classmates were born in July. This gives us a fraction of 15/125 = 3/25.
If there are 1,280 students in Emilio's school, the number of students that he can expect to have birthdays in July would be:
= 3/25 × 1280
= 153.6
There will be 153 students expected

Answer:
3 inches

The students at Plymouth South and the students at Plymouth North both planned trips to Six Flags. The students at South rented and filled 2 vans and 11 buses with 674 students. North rented and filled 6 vans and 14 buses with 882 students. Each van and each bus carried the same number of students. Find the number of students each van and In each bus. (Write your answer as an
Answer:
Number of vans = 7 students
Number of buses = 60 students
Step-by-step explanation:
Let
Number of vans = x
Number of buses = y
2x + 11y = 674 (1)
6x + 14y = 882 (2)
Multiply (1) by 3
6x + 33y = 2,022 (3)
6x + 14y = 882 (2)
Subtract (2) from (3)
33y - 14y = 2,022 - 882
19y = 1,140
y = 1,140 / 19
= 60
y = 60 students
Substitute y = 60 into
2x + 11y = 674 (1)
2x + 11(60) = 674
2x + 660 = 674
2x = 674 - 660
2x = 14
x = 14/2
= 7
x = 7 students

Which of the equations are true identities? \begin{aligned} \text{A. }&(y+6)(y-7)+42=y^2-y \\\\ \text{B. }&(x+3)(x-8)=x^2-5x \end{aligned} A. B. (y+6)(y−7)+42=y 2 −y (x+3)(x−8)=x 2 −5x
Answer:
Only A, the first equation is true.
Step-by-step explanation:
A. (y + 6)(y – 7) + 42 = y² + 6y –7y – 42 + 42 = y² – y. This means A is true
B. (x + 3)(X – 8) = x² + 3x – 8x – 24 = x² – 5x – 24. This means B is false.

Cecilia's mom ordered pizza for dinner. The pizza has two slices of pepperoni, two slices of mushroom, and two slices of anchovy. Cecilia asks her brother to bring her two slices. List all the possible combinations where the first choice is pepperoni.
Answer:
If the first slice is pepperoni, then we have left:
1 slice of pepperoni.
2 slices of mushrooms.
2 slices of anchovy.
Then the possible combinations are:
Pepperoni and pepperoni (in only one combination)
Pepperoni and mushrooms (in two combinations, because there are two slices left)
Pepperoni and anchovy (Again in two combinations, because there are two slices left)
These are the 3 possible combinations, 5 in total.

There are 70 students in the school band. 40% of them are sixth graders, 20% are seventh graders, and the rest are eighth graders.
How many band members are sixth graders?
Answer:
28 band members
Step-by-step explanation:
Since 40% of the band members are sixth graders, we need to take 40% of 70 total students.
40% of 70 = 0.40*70 = 28
So 28 band members are in sixth grade

I need help some help please
Answer:
1. no, 2. yes
Step-by-step explanation:
You need to use the triangular inequality thereom, which goes by if any side lengths are added together, they are greater than the remaining one. So, for number one, although 20+9=29>8 and 20+8=28>9, 9+8<20 since 9+8=17, which is less than 20. For number two, yes because 1) it is a right triangle triple and 2) 3+4=7>5, 4+5=9>3, and 5+3=8>4.
Answer:
Number 1 is Not a triangle so No and you don’t need to classify becuase it’s not aa triangle
Number 2 is a triangle becuase its ta Pythagorean triplet and even if you checK, it adds up.
Step-by-step explanation:
1) So using Pythagorean Theorem
8^2+9^2=20^2
64+91=400
That is not true
2) 3^2+4^2=5^2
9+16=25
That is true
