(1.)what is the value of 35−3m , when m = 4? a.1 b.13 c.23 d.128 (2.)what is the value of 1 + x ÷ 5, when x = 80? enter your answer in the box. (3.)evaluate the expression for the given values. mx−y when m=5, x=3, and y=8 enter your answer in the box. (4.)evaluate 3a+15+bc−6, when a=7, b=3, and c=15. enter your answer in the box.

1.) 35-3m

m= 4

35-3m

= 35-3(4)

= 35-12 (do the multiple/division first before doing the addition/subtraction)

= 23

C. 23

(2.) 1 + x ÷ 5

x = 80

1 + x ÷ 5

= 1+80÷5

= 1+16

= 17

(3.) mx-y

m=5, x=3, and y=8

mx-y

= 5(3)-8

= 15-8

= 7

(4.) 3a+15+bc−6

a=7, b=3, and c=15

3a+15+bc-6

= 3(7)+15+3(15)-6

= 21+15+45-6

= 75

Step-by-step explanation:

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.
