If it costs the store $60 to acquire a bike and it sells the bikes for $120 each, the store gets $60 of profit per bike sold.
If they need to get $24000, then they need to sell 400 bikes because 400 bikes x 60 is 24000

There are 10 2/15 kg of watermelons and coconuts on a truck. The weight of the watermelons is 3 3/5 times that of the coconuts.
JulijaS [17]

Answer:

2 7/76 kg

Step-by-step explanation:

Let the weight of

Watermelons = x

Coconut = y

There are 10 2/15 kg of watermelons and coconuts on a truck.

x + y = 10 2/15

x = 10 2/15 - y

x = 152/15 - y.... Equation 1

The weight of the watermelons is 3 3/5 times that of the coconuts.

x = 3 3/5 × y

x = 18/5 × y

x = 18y/5

How heavy are the coconuts on the truck, in kg?

Find y

We substitute 18y/5 for x in Equation 1

x = 152/15 - y

18y/5 = 152/15 - y

18y /5 + y = 152/15

Multiply through by 15

18y/5 × 15 + y × 15 = 152/15 × 15

3 × 18y + 15y = 152

54y + 15y = 152

69y = 152

y = 152/69

y = 2 14/152

y = 2 7/76 kg

Therefore, the weight of the coconuts are 2 7/76 kg

What two numbers multiply to get -140 but add to get -4
dalvyx [7]
In order to get -140, one number has to be negative and one number has to be positive.  And these two numbers when added together give you a -4, which means the greater of these numbers has to be negative.

Try guess and check strategy by listing possible factor combinations for -140 and see which one works!

Which simplified expression matches the set of tiles shown?
notka56 [123]

Answer:

The expression  - x² - x + 2  and   - x² + x + 2  matches the set of tiles

Step-by-step explanation:

Given four expression as :

A ) - x² - x + 2

solving by mid term breaking

Or,  - x² - 2 x + x + 2

Or,  - x ( x + 2 ) + 1 ( x + 2 )

or, ( x + 2 ) ( - x + 1 )

B )   x² - x + 2

solving by mid term breaking

Or,   x² - 2 x + x + 2

or,  x ( x - 2 ) + 1 ( x + 2 )

So, the expression will not break

C )  - x² + x + 2

solving by mid term break

Or,  - x² + 2 x - x + 2

or,  - x ( x - 2 ) - 1 ( x - 2 )

or,  ( x - 2 ) ( - x - 1 )

D )  x² + x + 2

solving by mid term break

Or, ) x² + 2 x - x + 2

Or,   x ( x + 2 ) - 1 ( x - 2 )

so, The expression will not break

Hence The expression  - x² - x + 2  and   - x² + x + 2  matches the set of tiles answer
