Answer:
cost of crab meals = $20
cost of vegetarian meals = $38
Step-by-step explanation:
Let
x = cost of crab meals
y = cost of vegetarian meals
Troop A
12 crab meals and 23 vegetarian meals, with total receipts of $916.
12x + 23y = 916
Troop B
12 crab meals and 12 vegetarian meals, bringing in a total of $696
12x + 12y = 696
12x + 23y = 916 (1)
12x + 12y = 696 (2)
Subtract (2) from (1)
23y - 12y = 916 - 696
11y = 220
y = 220/11
= 20
y = 20
Substitute y = 20 into (1)
12x + 23y = 916
12x + 23(20) = 916
12x + 460 = 916
12x = 916 - 460
12x = 456
x = 456/12
= 38
x = 38
cost of crab meals = $20
cost of vegetarian meals = $38
In parallelogram BCDE if CE= 32 find GF
Please help I’ll give brainliest
Answer:
CF = 16
Step-by-step explanation:
One if the properties of a parallelogram is that the diagonals of a parallelogram bisect each other. This implies that:
CF = ½ of CE
Since CE is given as 32, therefore:
CF = ½ of 32
CF = 16

Ibrahim has two lists of numbers. The mean of the numbers in the first list is p. The mean of the numbers in the second list is q. Ibrahim combines the two lists into one new list of numbers. Ibrahim says ‘The mean of the new list of numbers is equal to (p+q)/2 .' One of two conditions must be satisfied for Ibrahim to be correct. (b) Write down each of these conditions.
Step-by-step explanation:
The two conditions that must be satisfied for Ibrahim to be correct are:
1. The range of numbers in each list must also be the same.
2. The number of numbers in both list must also be same.

The slope is m=-7/3
m=y²-y¹/x²-x¹
m=(-1)-6/1-(-2)
m=-7/3
Draw a general schematic graph of the function y=kx+b, if k>0,b>0
I will give brainliest
Answer:
k ≠ 3
Step-by-step explanation:
Given the system of equation;
kx - y = 2 ------------------- 1
6x - 2y = 3 -------------------- 2
Rewriting the equations in the format ax+by+c = 0
Equation 1 becomes kx - y - 2 = 0
Equation 2 becomes 6x - 2y - 3 = 0
where a₁ = k, b₁ = -1 and c₁ = -2 and a₂ = 6, b₂ = -2 and c₂ = -3
For the system of equation to have a unique solution the following must be true;
a₁/a₂ ≠ b₁/b₁
Substituting the coefficients into the condition, we will have;
k/6 ≠ -1/-2
k/6 ≠ 1/2
Cross multiplying we will have;
2k ≠ 6
k ≠ 6/2
k ≠ 3
This means that k can be any other real values except 3 for the system of equation to have a unique solution.

There are 100 students and 5 teachers going on a field trip. Each bus can hold a maximum of 40
people. What is the fewest number of buses required for the field trip?
Answer:
So if you Divided the number of students to the number of the teachers you will have 19 students to each one teacher which means:
Step-by-step explanation:
100÷5=20 ( 19 students & 1 teacher )
science each bus can hold a maximum of 40 people.
100 = 20 20. 20. 20. 20
20 + 20 = 40 ( first bus )
20 + 20 = 40 ( second bus )
last 20 alone ( third bus )
The final answer is the fewest number of buses required for the field trip is 3 buses.
Solve for p: 3p+12=c+14
Answer:
p = [tex]\frac{c+2}{3}[/tex]
Step-by-step explanation:
Given
3p + 12 = c + 14 ( subtract 12 from both sides )
3p = c + 2 ( divide both sides by 3 )
p = [tex]\frac{c+2}{3}[/tex]

O D. Graph D
Answer:
A

A table contains the ordered pairs (3, 42.25) and (5, 50.75). If the relationship in the table is linear, explain how to find the initial value.
I need the answer quick, and thank you!!!
Answer:
First you can find the rate of change to be 4.25. Then you can subtract 4.25 repeatedly until you get to an output with an input of zero. The initial value is the output when the input is zero. The initial value after subtracting 4.25 three times is 29.50. Because the inputs go by 2, the rate of change is half the difference of the outputs, or 4.25. Subtract 4.25 repeatedly 3 times to get to an output with an input of 0. Calculate 42.25 – (3 x 4.25). The initial value is 29.50.
Hope this Helps!
Kristy asks Lonnie to think of a number , Add 3 to it, multiply the sum by 2, and then subtract 6. Let n stand for lonnie's starting number. Which expression represents Lonnie's final number?
Answer:
2(n+3) - 6 = 2n
Step-by-step explanation:
Let n stand for lonnie's starting number.
Kristy asks to add 3 to the number. It will become (n+3)
Now he ask to multiply the sum by 2. It will become 2(n+3).
Finally, he ask to subtract 6. It will become 2(n+3) - 6
The expression is : 2(n+3) - 6.
We can simplify it as follows :
= 2n+6-6
= 2n
Hence, the required expression is 2n.

no

Describe fully the single transformation that maps shape A onto shape B.
Answer:
The single transformation that maps shape A onto shape B is a reflection across the line y = 2
Step-by-step explanation:
The coordinates of the A are A(-1, 3)
The coordinates of the corresponding point on B is (-1, 1)
Therefore, given that the x-coordinates of the pre-image A and the image B are the same, therefore, we have that image B is a reflection of image A
Also half the vertical distance between figure A and B = (3 - 1)/2 = 1
Therefore, figure A is obtained from figure B by reflection across a horizontal line, 1 unit below the lowest y-coordinate of figure A which is the line y = 3 - 1 = 2
Therefore, we have;
The single transformation that maps shape A onto shape B is a reflection across the line y = 2
