Is 0.07 less than 0.06
Kobotan [32]
No, .007 is not less than .006. Not only is the decimal form evidence of these integers, but writing them as a percentage can also decipher the question.

Since .007 equals to 7% (0.07 = 7/100) and 0.06 equals to 6% (0.06 = 6/100) then 7% is greater than 6%, therefore, answering you question.

Consider the system of linear equations -4x+2y=4 ​ and 4x-y=-6 Which is different
Serjik [45]

Answer:

x= -2, y = -2

Step-by-step explanation:

Solve the following system:

{2 y - 4 x = 4 | (equation 1)

{4 x - y = -6 | (equation 2)

Add equation 1 to equation 2:

{-(4 x) + 2 y = 4 | (equation 1)

{0 x+y = -2 | (equation 2)

Divide equation 1 by 2:

{-(2 x) + y = 2 | (equation 1)

{0 x+y = -2 | (equation 2)

Subtract equation 2 from equation 1:

{-(2 x)+0 y = 4 | (equation 1)

{0 x+y = -2 | (equation 2)

Divide equation 1 by -2:

{x+0 y = -2 | (equation 1)

{0 x+y = -2 | (equation 2)

Collect results:

Answer:  {x = -2 , y = -2

The last one Please answer asap im still crying
Anna007 [38]

Answer:

He has 12 ten dollar bills

Step-by-step explanation:

Let t = number of 10 dollar bills

f = number of fifty dollar bills

t+f = 25  since he has 25 bills

solving for f

f = 25 -t

Then we know he has 770 dollars

10t+50f = 770

Using f = 25-t in the above equation

10t + 50 ( 25-t) = 770

Distribute

10t+ 1250 - 50t = 770

Combine like terms

-40t+1250 = 770

subtract 1250 from each side

-40t - 1250-1250 = 770-1250

-40t = -480

divide each side by -40

-40t/-40 = -480/-40

t =12

He has 12 ten dollar bills
