W = width
3w + 7 = length

Equation: 3w + 7 + w = 75
Combine like terms: 4w + 7 = 75
Subtract 7 to the other side: 4w = 68
Divide both sides by 4: w = 17

Width = 17
Length = 3(17) + 7, so 58

Answer:

w=7  5/8

l = 29.875

Step-by-step explanation:

We have to use system of equations here

Let l be length and w be width

l = 3w+7

w=l(1/3)-7

We can use the equation:

l+w+l+w = 75

2l+2w = 75

Now we substitute l for what we said above

2(3w+7)+2w=75

6w+14+2w=75

Combine like terms

8w+14=75

Subtract 14 on both sides

8w=61

w=7  5/8

We can use what we know about the relationship of the width and the length to find the length

7  5/8 * 3 + 7 = 29.875

l = 29.875

Ray Of Light [21]
The width would be 236 and the lengths would be 118

Use the equations 2L+W=472 and W*L=MAX
Change the first equation to W=472-2L and plug this into the other equation
(472-2L)(L)=MAX
472L-2L^2=M (take derivative)
472-4L=0 (set to 0 to find the max value)
4L=472 
L=118 
Plug into original to get W=236

Hope this helps!

5.1% < 0.51 please help been working on this all day I really need help
WITCHER [35]
You can write any decimal as a precent by moving the decimal 2 places to the right so 
0.51 = 51%
5.1% < 51%
5.1% < 0.51

or, any precent can be written as a decimal by moving the decimal points two point to the left so
5.1% = 0.051
0.051 < 0.51
5.1% < 0.51

Which of these are a trinomial
Salsk061 [2.6K]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

D) c^2+c+6

»»————- ★ ————-««  

Here’s why:  

  • A trinomial is a expression that consists of three terms.
  • A term can be a number, variable, or both numbers and variables that are multiplied together.
  • Answer choice 'D' has three terms, c², 'c', and '6'. Therefore, it is a trinomial.

Hope this helps you. I apologize if it’s incorrect.

Noah’s dog weighs 15 1⁄3 pounds (lbs). Aiden’s dog weighs three times as much as Noah’s. How many pounds does Aiden’s dog weigh?
SpyIntel [72]
<h3>Answer:  46 pounds</h3>

===============================================

Work Shown:

N = weight of Noah's dog = 15 & 1/3 pounds

A = weight of Aiden's dog = unknown

A = 3*N

A = 3*(15 & 1/3)

A = 3*(15 + 1/3)

A = 3*15 + 3*(1/3) .... distribute

A = 45 + 1

A = 46

Aiden's dog weighs 46 pounds.
