Sum of two numbers is 104 The larger number is 1 less than twice the the smaller number?
set up an equation. x+y=104. we'll say the larger number is y and the smaller number is x. y= 2x-1 (the larger number is 1 less than twice the smaller number.) substitute y into the original equation x+y=104. x+2x-1=104. add 1 to both sides. x+2x=105. add x+2x together. 3x=105. Divide 3 on both sides. x=35. plug that into the original x+y=104. 35+y=104. subtract 35 from both sides. y=69. You two numbers are: 35 and 69.
Let g(x) = 2x and h(x) = x2 + 4. Evaluate (h ∘ g)(−5)?

The middle angle in a triangle measures 1 degree more than 2 times the smallest angle and 53 degrees less than the largest angle Find the measure of angles of the triangle?
middle angle= 51 degrees smallest angle= 25 degrees largest angle= 104 degrees x=25 ; y=104 I can't really show you how I got the answer but I suggest you draw a picture and then it's much easier to figure out. We don't need a figure to compute the measure of the angles, since we know that the sum of the measure of angles in a triangle is 180 degrees. Let x be the smallest angle, so the middle angle is 1 + 2x, and the larger angle is 53 + 1 + 2x or 54 + 2x. Then we have: x + (1 + 2x) + (54 + 2x) = 180 5x + 55 = 180 5x + 55 - 55 = 180 - 55 5x = 125 5x ÷ 5 = 125 ÷ 5 x = 25 1 + 2x = 1 + 2(25) = 51 54 + 2x = 54 + 2(25) = 104
What is -2x plus 2x?
It is 2x+(-2x) = 0
Why is 2x cubed different from 2x times 2x times 2x?
2X * 2X * 2X = 8X^3 2X^3 is saying 2*( X * X * X) = 2X^3
How do you do 2x times 2x?
2x * 2x (2*2=4) therefore, 2x*2x equals 4x2.
A rectangle has perimeter 182in and length 52in.what is the width?
Let the width be x:- 2(x+52) = 182 2x+104 = 182 Subtract 104 from both sides and then divide both sides by 2 to find the width:- x = 39 inches Check: 2(39+52) = 182 inches
-2x - 6 equals 2x plus 6?
-2x-6= -2x-6Another answer:-2x-6 = 2x+6-2x-2x = 6+6-4x = 12x = -3
2x +2x + 2x=?
6x
