Answer:

25 and 55

Step-by-step explanation:

Let's call the larger number L and the smaller S

L = 5 + 2×S

And the sum is:

L + S = 80 Subtract S in both sides:

L = 80 - S

Now, substitute this value of L in the first equation:

80 - S = 5 + 2×S Add S in both sides:

80 = 5 + 2×S + S

80 = 5 + 3S Subtract 5 in both sides

75 = 3S Divide both sides by 3

25 = S

We find the value of S, and now we substitute it in the second equation to find the value of L:

L = 80 - 25

L = 55

Step-by-step explanation:

let the four blanks be

A     B

C     D

the x-value of each function is given on the leftmost column,

So,

A = 2 * (x^2) = 2 * (1^2) = 2 * 1 = 2

B = 2^x = 2^1 = 2

C = 2 * (x^2) = 2 * (2^2) = 2 * 4 = 8

D = 2^x = 2^2 = 4

Answer:

x = 18 or -18

Step-by-step explanation:

x^2 + 24^2 = 30^2

simplify

x^2 + 576 = 900

subtract 576 from both sides

x^2 = 324

Take square root of 324

+/- √324

x = 18 x = -18

18 or -18 is the answer

-4.5 / 4 = -1.125

Answer: -1.13, or -1 1/8

Step-by-step explanation:

Step-by-step explanation:

15 1/2+ 3/4=16 1/4

to add fractions what you want to do is this:

so you want them as the same denominator, a way to do this is multiply one denominator with another (ex, 2 in 1/2. you want to multiply 4 with 2 which equals 8 and 2 with 3. this together equals 6/8. do the same thing with 1/2. 1×4=4 2×4=8. 4/8)

so, whats 4/8 and 6/8? just adding it like usual, it'll be 10/8, or 1 2/8.

15+1 2/8=16 2/8

16 2/8 simplified (just divide by 2 until you make it to where you cant anymore)

16 1/4

do the same with the other adding ones.

23 1/6+8 3/4=23 11/12

15 2/5+ 2 2/6= 17 11/15

now, do the same way as showed before but except subtract.

9/10 - 3/5 = 15/50

7 3/4 - 5 5/8 = 1/8

20 5/8= 1/8

X = 3

Mode: 11median: 9

Step-by-step explanations

3x = 3*2 = 6

(6,7,8,8,9,10,11,11,11)/9 = 81/9 = 9

The value of X = 3

Mode: 11

Median: 9

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

Median represents the middle value of the given data when arranged in a particular order.

Mode is that number that appears most frequently in the given set of data.

We are given that  the ages in years of members of group 8, 11, 8,10 ,6, 7, 3x ,11, 11 if the mean age is 9 years

3x = 3(2 )= 6

Mean = (6,7,8,8,9,10,11,11,11)/9

= 81/9

= 9

I dont know the rest because the question is worded wrong

The equation that represents the number of magazines that he read (y) per week (x) will be y = 2.5x.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Billy read an average of 2.5 magazines each week during the year.

The equation that represents the number of magazines that he read (y) per week (x) will be

y = 2.5x
