Mathematics
1 answer:
____ [38]3 years ago
7 0

Answer:

No

Step-by-step explanation:

we have the number

7,027

we know that

7,027=7*1,000+2*10+7*1

so

The value of the first 7 is equal to

7*1,000=7,000

The value of the second 7 is equal to

7*1=7

therefore

7,000/7=1,000

The value of the first 7 is one thousand times greater than the second 7

The answer is no

solve for x

Apply distributive property right side

4x+7=1+4x+6

Combine like terms

4x+7=4x+7

subtract 4x both sides

7=7

The equation has infinity solutions

.All values of x make the equation true

You can mow one acre in 126 minutes. i can mow one acre in 117 minutes. how long will it take you to mow a 0.17-acre lawn? 13 in
Morgarella [4.7K]

a) (0.17 ac)×(126 min/ac) = 21.42 min

b) I can mow 1/126 ac/min; you can mow 1/117 ac/min. Together, we can mow at a rate that is the sum of these:

... (1/126 + 1/117) ac/min = (117 + 126)/(126×117) = 243/14,742 ac/min

Then it will take 14,742/243 min/ac × 0.17 ac/lawn ≈ 10.31 min/lawn
