janae saves dimes and quarters in a jar on her dresser. janae has 35 coins in the jar for a total of
$6.50. she has 5 more quarters than dimes. how many quarters are in the jar?

quarters are 20 in number.

Step-by-step explanation:

Let d represent dimes

Let q represent quarters

d + q = 35

q = d+5

d+d+5=35

2d=35-5

2d =30

d = 30/2

therefore dimes =15

Substitute d for 15 to solve for q;

q=15+5

therefore quarters are 20 in number.

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
