Answer:

  sometimes

Step-by-step explanation:

4 + 7 = 11 . . . not a multiple of 7

28 + 7 = 35 . . . a multiple of 7

If you add a multiple of 4 and a multiple of 7, the sum is <u>sometimes</u> a multiple of 7.

__

It will be a multiple of 7 when the multiple of 4 used is a multiple of 7, such as 4×7 or 4×14 or 4×21, for example.

Answer:

x=11

Step-by-step explanation:

the question would be to find x

3x + 28 + 5x + 52 + 2x - 10=180 (sum of angles in a triangle is equal to 180⁰)

10x + 70=180

10x=180-70

10x=110

x=110/10

x=11

Math help !! :) thanks!
Ber [7]

X= (-7,12)

Y= (7,-9)

The distance between the x points is 14 units

we want a ratio of 3 to 4

for every 3 on one side there are 4 on the other for 7 total

6 to 8   = 14

so 6 on one side 8 on the other

so 6 units on the left starting at -7

-7 + 6 = -1


same with y

12 to -9 is 21 units

3 to 4 = 7

6 to 8 =14

9 to 12 = 21

so 9 unit from the top

12-9 = 3

(-1,3)

Choice A

laila [671]

Answer

C. 49, 17, 4, 18

Step by step explanation

Here mean of all the data set is 88

To find the most spread of data, we need to find the range.

range of set A = The highest value - the lowest value = 36-6 = 30

Range of set B = 30-15 = 15

Range of set C = 49-4 = 45

Range of set D = 30-14= 16

Here the highest range is in Set C.

Therefore, answer is C. 49, 17, 4, 18
