How do I do this math problem can you please help me solve it
Gnom [1K]
First, multiply 1/2 and 2 by 6 to simplify the equation. Then, subtract 12 from both sides of the equation to get x alone. Finally divide both sides of the equation by 3 to get x on it's own. That is your solution. X=-2/3 I attached a picture of my work. Hope this helped!

The width of a rectangle is 3.4 feet. The perimeter is 12.6 feet what is the length
lesya692 [45]

Answer:

the answer is 2.90

Step-by-step explanation:

Picture a rectangle, if one side is 3.4 then the other side 3.4. Add those two togerther gives you 6.8. Now you can subtract 6.8 from the perimeter which is 12.6 then that gives you 5.8. Then you split the 5.8 which give you 2.90 which is the length of the rectangle. So if you label all the sides of the rectangle like this 3.4 + 3.4 + 2.90 + 2.90 = 12.6

One side of triangle is 5 more than 3 times the shortest side. The third side is 24 feet more than the shortest side. The perime
Feliz [49]

Answer:

17, 56, 41,

Step-by-step explanation:

"third side is 24 more than shortest side"

Let a be the shortest side.

c = a+24

"perimeter is 114"

a+b+c = 114

a+b+(a+24) = 114

2a + b = 90

"one side is 5 more than 3 times the shortest side"

That side must be b; c is an extraneous solution.

b = 3a+5

2a+(3a+5) = 90

a = 17

b = 56

c = 41

(a,b,c) = (17,56,41)

iren2701 [21]

Answer:

D

Step-by-step explanation:

If n=minimum number of required words and the essay is 175 words long which is 5 times more words than the minimum number of required words, you multiply n with 5 and equate to 175. To get n, you divide 175 with 5(175/5) which is 35 words.
