Mrs. Cooper has $20 can she buy a museum tickets for 10 year old daughter a ticket for a self and a book that cost 3.99? Explain
Sladkaya [172]

No, because then she would have to pay 21 dollars  as a total and she only has 20.

Add adult plus Child,

5.75 + 11.25 = 17

add that to the book's price,

17+3.99= 2.99

it will exceed the budget by 99 cents.

A rectangular field is 300 meters long and 250 meters wide. What is the area of the field in square kilometers
lidiya [134]

Answer:

0.075 sq km

Step-by-step explanation:

Given that there is a rectangular field with dimensions of length =300 m and width = 250 m.

We have to calculate area of this rectangle in the units of square kilometres.

Let us convert length and width into km

1000m = 1 km

Hence length = 300/1000= 0.3 km and

width = 250/1000 = 0.25 km.

ARea = length x width = 0.3 x 0.25

=0.075 square km.

Sophie [7]
c. (x + 5)(x - 7)    use the FOIL method.

x² + 5x - 7x - 35

x² + (5x - 7x) - 35   collect like terms.

x² - 2x - 35

Solve the inequality 3x-1>-6x​
Ghella [55]

Answer:

x > 1/9

Step-by-step explanation:

Given that:

3x-1>-6x​

Adding 6x + 1 on both sides we get

3x-1 + 6x + 1>-6x​ + 6x +1

3x +  6x > 1

Adding both variables

9x > 1

Dividing both sides b 9 we get

9x/9 > 1/9

x > 1/9

I hope it will help you!​
