3 0

Answer:

Step-by-step explanation:

Two consecutive integers be x  and (x+1)

x + x +1 = 7²

2x + 1 = 49

2x = 49 - 1

2x = 48

x = 48/2

x = 24

The consecutive integers are: 24,25

Question 1:
AnnyKZ [126]

Answer(1):

Given that h(y)=2y-7.

h(8) means  plug y=8 into h(y)=2y-7.

h(8)=2*8-7=16-7=9

Hence C) 9 is the final answer.


Answer 2:

(7/8) = (m/32)

to solve for m, we begin by cross multiply

8m=7*32

8m=224

m=28

Hence choice C) 28 is final answer.

B) the letter has reflection symmetry only

So B) is correct.


Answer 4:

Which statement is true?

PLS HELP IM BEGGING U
expeople1 [14]

Answer:

answer is 57.

Step-by-step explanation:

Given

m<6= x - 8

m<7 = 2x - 7

We know

<6 + <7 = 180° [ being linear pair ]

x - 8 + 2x - 7 = 180°

3x - 15 = 180°

3x = 180° + 15°

3x = 195°

x = 195° / 3

x = 65°

Now

m<6= x - 8 = 65° - 8° = 57°

hope it helps :)
