Solve for d:
d+(−5.004)=2.826

d =7.83

Step-by-step explanation:

d+(−5.004)=2.826

Add 5.004 to each side to isolate d

d+(−5.004)+ 5.004=2.826+5.004

d =7.83

7.83

Step-by-step explanation:

d+(−5.004)=2.826

d −5.004 = 2.826

d = 2.826 + 5.004

d = 7.83

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
