1.Which statement about the equation is true? x + 2 = x + 4 2. 5(w−1)−2=5w+7

Mathematics
1 answer:
Marysya12 [62]2 years ago
7 0

Answer:

Both equations have no solution.

Step-by-step explanation:

The first equation is:

x + 2 = x + 4

Group the similar terms to get:

x  - x =  4 - 2

0 =  - 2

This equation has no solution because

0 \ne - 2

The second equation is

5(w - 1) - 2 = 5w + 7

We expand the parenthesis to obtain:

5w - 5 - 2 = 5w + 7

5w - 7= 5w + 7

Group similar terms:

5w -5w = 7 + 7

0 = 14

This equation does not also have solution because

0 \ne14

In June, you bought 14.5 gallons of gasoline for $3.18 per gallon. The following February, you bought the same amount of gasolin
Nata [24]

Answer:

14.5 × 3.18 - 14.5 x 1.88

You paid $18.85 more in june than in February

Step-by-step explanation:

In order to find the answer to this question you will need to find how much you paid in June and how much you paid in February.

ex.14.5 x 3.18 - 14.5 x 1.88

To solve this you need to find the product of 14.5 x 3.18 and 14.5 x 1.88 and then subtract them from eachother.

ex.14.5 x 3.18 =46.11

14.5 x 1.88=27.26

46.11-27.26=18.85
