Answer:
Step-by-step explanation:
3m + 7 = - 23
we pass the -7 to the right with a positive sign
3m = -23 - 7
we perform the sum of negative numbers
3m = -30
we pass the -3 to the right to divide
m = -30/3
we perform the division
m = -10

Step-by-step explanation:
The distance (d) in meters that an ant can travel varies directly with the amount of time (t) in hours it spends walking. assume that an ants constant off proportionality is 18.write the equation to the represent the proportional relationship between d and t using the information given. What does the constant of proportionality represent in this problem?
The constant is 18
To find distance (d) you would multiply the constant by the time(t).
D = 18t
Distance is speed x time, so the given constant would be the speed of the ant.

Answer:
13) 28
14) 22
15) 24
16)13
Step-by-step explanation:
13) Because they all lie on the same line, AC would be AB+BC, or 16+12, or 28.
14) Same thing as 13, 13+9=22
15) Same thing as others but make an equation
-1+2x+11=3x+3
Simplifying the equation, we get x=7. Now, we plug in x=7 to 3x+3 to get AC.
3(7)+3=21+3=24
16) build the equation:
x+14+x+10=22
2x+24=22
2x=-2
x=-1
Now plug in x=-1 to x+14.
-1+14=13

Answer:
∡BEN=122
x=17
Step-by-step explanation:
Since you know that when two sides are congruent like this then the to angles are congruent then you know that angle BNE equals 29.
Once you know that since we know that 180 is the sum of all three angles set an equation like this:
180=29+29+(11x-65)
Take off parentheses since you can't simplify in them.
180=29+29+11x-65
Combine like terms.
180=11x-7
Solve for x.
187=11x
x=17
Plug that in to (11x-65) to find angle BEN
angle BEN = 11(17)-65
angle BEN=122

The basketball team scored a total
of 80 points, all off of 2-point
baskets and 3-point baskets (no
they didn't make any free throws). If
six 3-point baskets were made, find
the number of 2-point baskets
made.
Answer:
31 2-point baskets were made
Step-by-step explanation:
We can find how many of the 80 points were made with 2-point baskets by subtracting all the points gained through 3-point baskets. Since there are six 3-point baskets:
# of points through 2-point baskets = 80 - 6(3) = 80 - 18 = 62
To find the number of 2-point baskets that were made, divide the points by the worth of the basket:
# of 2-point baskets made = 62/2 = 31
9514 1404 393
Answer:
31
Step-by-step explanation:
6×3 = 18 of the 80 points were from 3-point baskets, so the remaining 62 points were 2-point baskets.
62 = 2b
62/2 = b = 31
31 2-point baskets were made.
Emma is building a scale model of a jet airplane. The real airplane has a wingspan of 200 feet and a length of 240 feet. If Emma’s model has a wingspan of 30 centimeters, what is the length of the model ?
Answer:
Since it is a to-scale model,
the ratio of the wingspan to the length of both the airplanes must be equal
wingspan1 = 200 ft wingspan2 = 30 cm
length1 = 240 ft length2 = x cm
wingspan1 / length1 = wingspan2/length2
replacing the variables
200 / 240 = 30 / x
x = 30 * 240/200
x = 36 cm
Therefore, the length of Emma's airplane is 36 cm

Homer sold cupcakes and cookies yesterday. Each cupcake sold for $2.25 and each cookie sold for $0.25. At the end of the day, Homer has sold $55.50 worth of cookies and cupcakes. If he sold 54 cupcakes and cookies combined, how many cupcakes were sold and how many cookies were sold
Answer: 21 cupcakes and 33 cookies were sold.
Step-by-step explanation:
Let x= Number of cupcakes
y = Number of cookies
As per given,
x+y= 54 (i)
Cost: 2.25x+0.25y=55.50 (ii)
Multiply 0.25 to (i0, we get
0.25x+0.25y = 0.25(54)
⇒0.25x+0.25y = 13.5 (iii)
subtract (iii) from (ii), we get
2x=42
Divide both sides by 2, we get x= 21
Put this in (i) , we get 21+y =54 ⇒ y= 54-21= 33
Hence, 21 cupcakes and 33 cookies were sold.

What is the interquartile range of the following data set?

a.45
b.33
c.27
d.60
(apex)
Answer:
The interquartile range is 60 ⇒ D
Step-by-step explanation:
The interquartile range is the difference between the upper quartile and the lower quartile
Let us explain how to find the interquartile range
Arrange the number from smallest to greatestFind its median Q1 (the middle number in the set of numbers)Find the lower quartile Q1 which is the median of the set of the numbers before the median Find the upper quartile Q3 which is the median of the set of the numbers after the median Subtract Q1 from Q3 the answer is the interquartile rangeLet us do these steps to find it
∵ The data set is {45, 12, 48, 96, 61, 84, 29, 1, 72, 5, 14}
→ Arrange them
∴ The data set is {1, 5, 12, 14, 29, 45, 48, 61, 72, 84, 96}
∵ They are 11 numbers
∴ The middle number is the 6th number (5 before it and 5 after it)
∵ The 6th number is 45
∴ The median is 45
→ Find the lower set (before the median)
∴ The lower set is {1, 5, 12, 14, 29}
→ Find the lower quartile Q1
∵ The lower quartile is the middle number in this set
∵ There are 5 numbers
∴ The middle one is the 3rd
∵ The 3rd is 12
∴ Q1 = 12
→ Find the upper set (after the median)
∴ The upper set is {48, 61, 72, 84, 96}
→ Find the upper quartile Q3
∵ The upper quartile is the middle number in this set
∵ There are 5 numbers
∴ The middle one is the 3rd
∵ The 3rd is 72
∴ Q3 = 72
→ Subtract them to find the interquartile range
∵ The interquartile range = Q3 - Q1
∴ The interquartile range = 72 - 12
∴ The interquartile range = 60
