Solve for y.
2y + 3y =30
Simplify your answer as much as possible.
(Im pretty stupid 0-0)
Answer:
y = 6
Step-by-step explanation:
2y + 3y = 30
Add like terms, as in same variable
5y = 30
divide both sides by 5, because u want to solve for y not 5y
y = 6

5)Trevon's school is selling tickets to the annual dance competition. On the first day of ticket sales
the school sold 5 senior citizen tickets and 8 student tickets for a total of $94. The school took in
$164 on the second day by selling 10 senior citizen tickets and 13 student tickets. Find the price
of a senior citizen ticket and the price of a student ticket
Answer:
$8 for student tickets and $4.40 for senior tickets
Step-by-step explanation:
10 (5x +8y=94)
5 (10x +13y=164)
50x+80y=940
- 50x +65y=820
80y-65y= 940-820
15y= 120/15
y=8
(y is the cost of student tickets)
5x+8y=94
5x+8(9)=94
5x+72=94-72
5x=22/5
x= 4.4

what is the simplest form of 3x^3 + x^2 + 2 ( x^3 - 4x^2 )
Answer:
−8x^4 + 5x^3 + x^2
Step-by-step explanation:
3x^3 + x^2 + 2 (x^3 − 4x^4)
Apply the distributive property.
3x^3 + x^2 + 2x^3 + 2 (−4x^4)
Multiply −4 by 2.
3x^3 + x^2 + 2x^3 − 8x^4
Simplify by adding terms.
Add 3x^3 and 2x^3.
5x^3 + x^2 − 8x^4
Simplify the expression.
Move x2.
5x^3 − 8x^4 + x^2
Reorder 5x^3 and −8x^4.
−8x^4 + 5x^3 + x^2
What is the positive solution for (x-4)(x+5) = 0
Answer:x=4
Step-by-step explanation:
You can split this up into two equations
x-4=0
x+5=0
To solve each:
x-4=0
Add 4 to each side
x=4
------------
x+5=0
Subtract 5 from each side
x=-5
So your two solutions are -5 and 4 but you want the positive one so the answer is x=4

CAN SOMEONE PLEASE HELP ME I'LL GIVE YOU BRAINLIEST
Answer:
x = 25
Step-by-step explanation:
From the given picture,
In ΔMLN,
m∠NML + m∠MLN + ∠LNM = 180°
61° + 39° + m∠LNM = 180°
100° + m∠LNM = 180°
m∠LNM = 180° - 100°
m∠LNM = 80°
If JK║MN and JN is a transverse intersecting these parallel lines at N and J,
∠LNM ≅ ∠LJK [Alternate interior angles]
(3x + 5)° = 80°
3x = 80 - 5
3x = 75
x = 25

Step-by-step explanation:
A ramp for wheelchair access to the gym has a slope of 5% (that is, the ramp rises 5 feet vertically for every 100 feet of horizontal distance). The entire ramp is built on level ground, and the entrance to the gym is 2 feet above the ground. What is the horizontal distance, in feet, between the ends of the ramp? a 4 b 10 c 40 d 100 e 400
Answer:
C 40
Step-by-step explanation:
Using proportions, it is found that the horizontal distance, in feet, between the ends of the ramp is:
c 40
This question is solved by proportions, using a rule of three.The slope of 5% means that when the vertical distance rises by 5 feet, the horizontal distance changes by 100 feet.What is the horizontal distance for a vertical distance of 2 feet?The rule of three is:
5 feet V - 100 feet H
2 feet V - x feet H
Applying cross multiplication:
[tex]5x = 200[/tex]
[tex]x = \frac{200}{5}[/tex]
[tex]x = 40[/tex]
Hence, 40 feet, option c.

Erin's family has completed 70% of a trip. They have traveled 35 miles.
How far is the trip?
Answer:
Their trip is 50 mile long.
Step-by-step explanation:
I first divided 70 by 35 to get two.The two represents 1 mile = 2%. So then I subtracted 70 from 100 to get 30 then I divided 30 by 2 to get 15. Then I added 15 to the original 35 to get 50 miles for their 100%/destination of their trip. Hope this helps! Have a great day!
