I need help with these 2 questions my dudes. I have tried solving them, but I don't know what I'm doing.

0.1$ per apple

9.5$ per 35 apples

65 apples picked by Matteo

Step-by-step explanation:

Part D

That point on the graph (100, 16) is a hint, it means that for x= 100 apples the pay is P= 16

the equation is: P=bx+6

now we can substitute the values of the hint like this:

16=100b+6

10=100b

b=1/10=0.1 $ per apple

if one picked 35 apples she would get P=0.1*35 + 6 = 9.5$

Part E

you can write as equations

M=apples picked by Matteo

B=picked by Brooke=2M (twice as much as Matteo)

A=picked by Addie = M-20 (20 fewer than Matteo)

K=picked by Khan=M+50 (50 more than Matteo)

you know that M+B+A+K=355

and you can expresso those values in terms of Matteo like this

M+(2M)+(M-20)+(M+50)=355 those parenthesis are there only to show you each single substitution clearly

M+2M+M-20+M+50=355

5M=325

M=325/5 = 65

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
