7x+8(x+1/4)=3(6x-9)-8 need a solution for this problem
valentina_108 [34]
7x+8(x+1/4) = 3(6x-9)-8
7x+8x+2      = 18x - 27 -24
15x + 2        =  18x - 51
       +51                        + 51
15x + 53      = 18x
-15x             = -15x
          53       = 3x
          17.66  = x

Riley adds 45.3 and 3.21 should his sum be greater than or less than 48 tell how you know
Romashka [77]

His sum should be more than 48.

I know because if you throw away the decimal pieces
and just add up the whole numbers  45  and  3 ,
right there you would have 48 .  So when you include
the decimal pieces, they'll make it even bigger.

A private airplane leaves an airport and flies due east at 192 km/hr. Two hours later, a jet leaves the same airport and flies d
elixir [45]
The answer is 0.5 hours.

A velocity (v) of an object is a distance (d) divided by time (t):
v = d ÷ t                         ⇒                  t = d ÷ v

It is given:
v1 = 192 km/h
v2 = 960 km/h
t1 - t2 = 2h
We need to calculate t2.

Since they will travel the same distance before the jet overtakes the plane, we can say that d1 = d2 = d

Now, let's express t1 and t2:
t1 = d/192
t2 = d/960

Therefore: d/192 - d/960 = 2
The least common denominator is 960, so:
5d/960 - d/960 = 2
4d/960 = 2
4d = 2 · 960
4d = 1920
d = 1920 ÷ 4 = 480 km

Now t2 = d/960 = 480/960 = 0.5 hours.
