One way of doing this is to write the equation of ratios (15 screwdrivers / 45 screwdrivers) = ($300 / x). Solve this equation for x. To do this, you might try multiplying both sides of this equation by x to eliminate fractions.
Another way is to obtain the unit cost of each screwdriver and then multiply the result by 45 screwdrivers.
Answer:
15
Step-by-step explanation:
(12/8) ×10 is the correct answer
Answer:
x= -8 , x=5
Step-by-step explanation:
2x^2+6x-80=0
x^2+3x-40=0
look for 2 numbers that their:
sum = 3
product = -40
(x+8)(x-5)=0
thus
x= -8 , x=5 (ANS)
Lim X/SIN5X=lim 5X/5SIN5X=1/5
