Answer:
9. x=-6, y=0
10. x=-9, y=-10
11. x=3, y=-1
Step-by-step explanation:
[tex]2x-9y=-12\\3x+18y=-18[/tex]
Multiply the first equation by 2.
[tex]4x-18y=-24\\3x+18y=-18[/tex]
Add the equations.
[tex]7x=-42[/tex]
[tex]x=-6[/tex]
We figured out x now we have to figure out y. To figure out y plug in x into any equation.
[tex]2(-6)-9y=-12[/tex]
[tex]-12-9y=-12[/tex]
[tex]-9y=0[/tex]
[tex]y=0[/tex]
Your answer is x = -6 and y = 0 for number nine.
[tex]6x+3y=24\\2x+3y=-12[/tex]
Change the signs of the second equation becuase 3y and 3y are both positive. We need one of them to be negative.
[tex]6x+3y=24\\-2x-3y=12[/tex]
Add them.
[tex]4x = 36[/tex]
[tex]x=9[/tex]
Now we have to figure out y.
[tex]2(9)+3y=-12[/tex]
[tex]18+3y=-12[/tex]
[tex]3y=-30[/tex]
[tex]y=-10[/tex]
x=-9 and y=-10 is your answer to number ten.
[tex]10x+5y=25\\-7x-3y=-18[/tex]
[tex]30x+15y=75\\-35x-15y=-90[/tex]
[tex]-5x=-15[/tex]
[tex]x=3[/tex]
[tex]-7(3)-3y=-18[/tex]
[tex]-21-3y=-18[/tex]
[tex]-3y=3[/tex]
[tex]y=-1[/tex]
x=3 and y=-1 is the answer to number eleven. I hope this helps! Let me know if I got anything wrong.

Jada has a monthly budget for her cell phone bill. Last month she spent 120% of her budget, and the bill was $60. What is Jada’s monthly budget?
Answers
Answer: The answer is $50.
Reasoning: If 120% equals to $60, then you can use the rule of three to calculate the value for 100%. Cross multiply, the answer will be $50.
48 is her monthly budget
Reasoning:
This word problem is telling us that $60 is 120% of her budget. To find her monthly budget, we need to find 100% of her budget. To get 100% we need to get rid of 20%.
This means the first step in this problem is finding 20% of 60. 20% of 60 is 12.
After you get 12, subtract it from 60. 60 - 12=48. 48 is her monthly budget.

HELP, DUE IN 15 MINUTES! In triangle ABC, the measure of ∠B is 90°, BC=16, and AC=20. Triangle DEF is similar to triangle ABC, where vertices D, E, and F correspond to vertices A, B, and C, respectively, and each side of triangle DEF is [tex]\frac{1}{3}[/tex]
the length of the corresponding side of triangle ABC. What is the value of sinF?
Answers
Answer:
Triangle ABC is a right triangle with its right angle at B. Therefore, AC is the hypotenuse of right triangle ABC, and AB and BC are the legs of right triangle ABC. According to the Pythagorean theorem
Step-by-step explanation: AB=202−162=400−256=144=12
Since triangle DEF is similar to triangle ABC, with vertex F corresponding to vertex C, the measure of angle∠F equals the measure of angle∠C. Therefore, sinF=sinC. From the side lengths of triangle ABC,
sinF=oppositesidehypotenuse=ABAC=1220=35
Therefore, sinF=35.
The final answer is 35 or 0.6.

x = 5
Answer 20:-
80 + 20x = 300
20x = 220
x = 11
Answer:
19. x = 5
This is because Elise need $20, so we are going to figure out x
First, subtract 10 by both sides
2x = 10
Then, divide both sides by two to isolate the variable
x = 5

Mr. Santos treated his students to a movie for winning the state contest. This also required taking some of the students’ parents as chaperones. The movie theatre charges $4 for each student and $6 for each adult. If Mr. Santos spent $180 on movie tickets and took 40 people (including himself), how many students did he take to the movies.
write two equations to help find the answer
Answers
Answer: 41
Step-by-step explanation:
Using a system of equations, it is found that he took 30 students to the movies.
------------------------------
This question is solved using a system of equations, and I will say that:
x is the number of students taken.y is the number of adults taken.------------------------------
40 people were taken, and thus:
[tex]x + y = 40[/tex]
As we want the number of students x, we can represent y as function of x, thus:
[tex]y = 40 - x[/tex]
------------------------------
Each student costs $4.Each adult costs $6.The total amount spent was $180.Thus:
[tex]4x + 6y = 180[/tex]
Since [tex]y = 40 - x[/tex]
[tex]4x + 6(40 - x) = 180[/tex]
[tex]4x + 240 - 6x = 180[/tex]
[tex]-2x = -60[/tex]
[tex]2x = 60[/tex]
[tex]x = \frac{60}{2}[/tex]
[tex]x = 30[/tex]
He took 30 students to the movies.
