1st question : Htwe Htwe made 500 cookies. She sold ¾of them and gave ⅖ of the remainder to all her friends. How many cookies were left? 2nd question : 1½ + ⅘ ÷ ⅜ x 10 ⅚?

75 cookies

Step-by-step explanation:

500 × 0.25(3/4 cookies sold)= 125

125 - 0.4(2/5 gave to her friends) = 75

75 cookies remain

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
