Let's say the price of the red tube is x, and the price of the blue tube is x + 7. Then the total cost 25 is the price of the red tube plus that of the blue tube, or x + x + 7.

The red tube cost £9, and the blue tube cost <span>£16.</span>
Write and solve an equation:
Total earnings = $782.75 = s(40 hrs) + 1.5*s*(7 hrs)
Then 782.75 = 40s + 10.5s = 50.5s
Dividing both sides by 50.5: s = 15.5. The attendant's regular hourly wage was $15.50.
5x2=10
10+20=30
30 is the answer.
Answer:
A
Step-by-step explanation:
Using the definition
n
= 
where n! = n(n - 1)(n - 2).... × 3 × 2 × 1
Then evaluating numerator and denominator
10
= 
= 
Cancel 7(6)(5)(4)(3)(2)(1) on numerator/ denominator, leaving
=
=
= 120
-------------------------------------------------------------------------------------
6
= 
= 
Cancel 4(3)(2)(1) on numerator/ denominator, leaving
=
= 15
-------------------------------------------------------------------------------------
Dividing numerator by denominator gives
= 8 → A
The answer is B. If 1 kilogram is 1,000 grams and mary needs 2 kilograms of potatoes she would multiply 2 by 1,000 equaling 2,000.
