The sum of two numbers is 20 and their difference is 12.

4 and 16

Step-by-step explanation:

First, let's find first term using sum formula:

We know that d or common difference is 12 and only sum of two terms so n = 2.

Since sum of two numbers equal 20.

From above, subtract both sides by 12, solving for a1.

Therefore our first number is 4.

Finding next number, create an equation:-

Another number is 16

So 4 and 16 has 12 as difference because 4+12=16 and 16-12 = 4

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
