Q: How do i use 4 2's and 1 3 to make 50?

Write your answer...

A = (s, 2s), B = (3s, 8s) The midpoint of AB is C = [(s + 3s)/2, (2s + 8s)/2] = [4s/2, 10s/2] = (2s, 5s) Gradient of AB = (8s - 2s)/(3s - s) = 6s/2s = 3 Gradient of perpendicular to AB = -1/(slope AB) = -1/3 Now, line through C = (2s, 5s) with gradient -1/3 is y - 5s = -1/3*(x - 2s) = 1/3*(2s - x) or 3y - 15s = 2s - x or x + 3y = 17s

5 and 1/2's, 6s, 6 1/2s, 7s, and 7 1/2s

2s + 17 = 2s + 17 1) First, you want to start on the left side of the equation and subtract 17 from both sides. 2s = 2s 2) Then, you take the 2 on the left side and divide it on both sides. s = s 3) You are left with s (Or 1s) on both sides, so s = 1.

Points: (s, 2s) and (3s, 8s) Slope: (8s-2s)/(3s-s) = 6s/2s = 3 Perpendicular slope: -1/3 Midpoint: (s+3s)/2 and (2s+8s)/2 = (2s, 5s) Equation: y-5s = -1/3(x-2s) => 3y-15s = -1(x-2s) => 3y = -x+17x Perpendicular bisector equation in its general form: x+3y-17s = 0

2 + 2 + 2 + 2/2 = 6 - 1 = 5

It is found as follows:- Points: (s, 2s) and (3s, 8s) Slope: (2s-8s)/(s-3s) = -6s/-2s = 3 Perpendicular slope: -1/3 Midpoint: (s+3s)/2 and (2s+8s)/2 = (2s, 5s) Equation: y-5s = -1/3(x-2s) Multiply all terms by 3: 3y-15s = -1(x-2s) => 3y = -x+17s In its general form: x+3y-17s = 0

Computers use and send information by using 1's and 0's. Not 2's and 10's.

well quite an unique question.there are many ways by which you can make 3 with coins some of them are listed below.starting with initials-2 +11 +1 + 150 + 50 + 50 + 50 + 50 + 50 ( 50 + 50 = 1Rs) 2 + 50 +50.................................................................and so on

(2+2+2) * 2 + (2/2) = 6 * 2 + 1 = 12 + 1 = 13.

u can use 20 pennies 1 quarter and 1 nickel

50% = 1/2

This is easy. Make two equations, and represent the sandwiches with s and the drink with d. you get: 2s+d=10 s+2d=8 After simplifying and taking away a variable, you figure out that each sandwich costs 4 dollars and each drink costs 2 dollars. (Heres the step by step algebra) 2s +dy = 10 s + 2d = 8 2s + d = 10 2s + 4d = 16 3d = 6 d = 2 2s + d = 10 2s + 2 = 10 2s = 8 s = 4 So, Sandwich = £4 Drink = £2

If p = 2s + 5, then s = (p-5)/2 or 1/2 (p-5) --- p = 2s +5 p-5 = 2s (p-5)/2 = s

Number 2S

Yes

It has 17 of them with a remainder of 1

A 50 scale is used to make measurements on a construction plan. If a plan is said to be in 50 scale, then a length of one inch on the ruler is the equivalent of 50 feet on the plan.

1s + 1s + 1 = 2s + 1

4 $2s, 1 $5, 1 $50, 2 $20s

If you mean: 4(2s-1) = 7s+12 then the value of s works out as 16

i use 40:1 you can use 44:1 50:1 and some more but this is what i recommend

150 g x 1 mol/68.154 g = 2.2 moles (2 sig figs)
