Will has $1.67 in pennies and quarters. his number of pennies is five more than twice the number of quarters. how many pennies does he have?

p = pennies

q= quarters

p = 2q+5   (1)

.25q+.01p=1.67   (2)

substitute  the equation for pennies (1) into the 2nd equation

.25q+.01(2q+5)=1.67

distribute

.25q +.02q +.05 = 1.67

combine like terms

.27q +.05 =1.67

subtract .05 from each side

.27q = 1.62

divide by .27

q=6

p=2q+5

p=2(6)+5

p=12+5

p=17

There are 6 quarters and 17 pennies

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'.
