Answer:
$18
Step-by-step explanation:
Let x represent the cost of an adult meal (the value we want to know). The cost of a student meal is half that, or x/2. The total cost of all the meals is ...
60(x/2) +32x = 1116
62x = 1116 . . . . . collect terms
x = 1116/62 = 18 . . . . divide by 62
The cost of an adult meal is $18.
_____
Additional comment
You can instead use a variable for the cost of a student meal, or you can use variables for both:
a = 2s
32a +60s = 1116
It makes sense here to solve this by eliminating the s variable in any of several ways, since you ultimately want to know the value of 'a'.

Which fraction is between 12 and 1?
only answer the “find the error” question…
Answer:
The x's in the coordinates are not supposed to be negative; the y's should be negative instead.
Step-by-step explanation:
If the x's are negative, it will flip the triangle over the y-axis; therefore, the y's have to be negative instead, which will flip it over the x-axis.
Answer:
The x's in the coordinates are not supposed to be negative; the y's should be negative instead.

The graph below represents the number of balls thrown over time. What is the constant of proportionality? PLSSS HELPPPPPPPPPPPPPPPPPPPPPP
Help me pleaseee! also fill in blanks!
for 1 serving the ratio is 1 : 2
for 2 servings the ratio is 2 : 4
so by looking at the two ratios above you can see that
for two servings the ratio 1 : 2 is multiplied by two
so the answer for 5 servings is 5 : 10
so no matter the number of servings when you simplify the ratio the ratio you should obtain (as in this case) should be 1:2 which the ratio for 1 serving.

2.Trig problem, plss help
no idea
Step-by-step explanation:
What is the effect of multiplying both sides of an inequality by a negative number? Explain and give an example.
Let's say we start with the true statement that 2 < 5
Multiplying each of those numbers by -1 means we have...
2 turn into -25 turn into -5If the inequality sign stayed the same, then we'd have the false statement -2 < -5. Use a number line to see why this is false. Note how -2 is to the right of -5, so it should be larger.
To fix this error, we flip the inequality sign.
So we go from 2 < 5 to -2 > -5
Rule: Multiplying both sides by a negative number always flips the inequality sign.

Special Pairs of angles and Classifying Triangles (PLEASE HELP)
Answer for Practice 8-4:
1. Right, Scalene
2. Acute, Isosceles
3. Obtuse, Scalene
4. Isosceles
5. Scalene
6. Equilateral
7. Scalene
8. Acute
9. Obtuse
10. Right
11. Right
12. This cannot be done because a right triangle always has two acute angles (cannot be right-angled and obtuse-angled at the same time)
14. Can't be done because a scalene triangle has no congruent sides, while isosceles triangles have two equal sides and two equal angles.
Simplify
-(w+4)+2(4w-4)
help plz :’)
Answer:
The simplified answer is 7w - 12.
Step-by-step explanation:
-1(w+4) + 2(4w-4)
(-w -4) + (8w - 8)
7w - 12
Answer:
7w - 12
Step-by-step explanation:
-(w+4)+2(4w-4)
Step 1: Distribute
In this equation, there are two things being distributed, the -(w+4) and the 2(4w-4). Looking at -(w+4) makes you think that there is nothing to distribute but actually there is. Treat the - like a -1 so that it looks like -1(w+4) and then we distribute normally.
-1 x w = -w
-1 x 4 = -4
Put it together and you have:
-w-4
Then the 2(4w-4), with this, we need to distribute the 2 into the 4w and -4. To do this, you just multiply the numbers.
2 x 4w = 8w
2 x -4 = -8
Put those together and you have:
8w-8
After distributing, the equation should like:
-w-4+8w-8
Step 2: Combine Like-Terms
In the remaining equation, there are 4 things we can combine. The -w and 8w, and the -4 and -8. The reason that we are doing it in this order is because you cannot combine a number with a variable, like combining -4 with 8w. Now we just add (or subtract).
8w - w = 7w
-4 - 8 = -12
Leaving us with the fully simplified equation:
7w - 12

Can somebody explain how to find an area of a square?
Please note that the area's side lengths are all the same.
(The side lengths are all 1/3 or also known as 0.3333)
Answer:
0.66653334
Step-by-step explanation:
The area of the face of the square is the side length x the side length. So 0.3333 x 0.3333 = 0.11108889. Since a square has 6 sides, multiply 0.11108889 with 6. So it equals 0.66653334.

There are several ways of writing these into a verbal phrase, but this is how I would do it:
9) 9 times a number
10) 14 is the difference between a number and 8
11) 24 is the quotient of a number and 12
(or "24 is a number divided by 12")
