The first side of a triangle measures 3 in. less than the second side, the third side is 2 in. more than the first side, and the
Debora [2.8K]

Answer:

P = 3x - 4

Step-by-step explanation:

Side 1 = x - 3

Side 2 = x

Side 3 = 2 + (Side 1) = 2 + x - 3 = x - 1

Perimeter = 20 in

Perimeter = Side 1 + Side 2 + Side 3

Perimeter = (x - 3) + (x) + (x - 1)

Perimeter = x - 3 + x + x - 1

Perimeter = 3x - 3 - 1

Perimeter = 3x - 3 - 1

Perimeter = 3x - 4

P = 3x - 4

What is the solution of the equation w – 8 =5? Show your work
Marta_Voda [28]

Answer:

Step-by-step explanation:

first one: w-8 =5

reverse it-  8+5= 13         so 13-8= 5

second one: 5x-2

2x-2+3x  << group together the x's

2x+3x=5x and you'll end up with 5x-2

last one: r/5=-9

again, reverse it-  -9 x 5 = -45

a negative times a positive = a negative

Seven more than three times a numberis 49 what is the number
Sunny_sXe [5.5K]
Seven more than 3 times a number is equal to 49 can be put into an equation form, which would be 7 + 3x = 49. With this equation we can work it out, first we will subtract 7 from both sides of the equation to cancel out the 7. 49 - 7 = 42. Now we have 3x = 42. To isolate x and give us the answer we will divide by 3 on both sides, since 3 is being multiplied by x. This will give us our answer, which is 14.
