How is solving 2x+c=d similar to solving 2x+1=9 for x? How are they different? How can you use x+c=d to solve 2x+1=9?
valentinak56 [21]

Answer:

No

Step-by-step explanation:

We can't use 2x + c = d for solving 2x + 1 = 9 . Here we can find the value of x from 2x + 1 = 9.

2x + 1 =9\\=>2x=9-1\\=>2x=8\\=>x=4

Putting the value of x in 2x + c = d :-

2x+c=d\\=>2*4+c=d\\=>8+c=d

But still we don't know the exact value of c & d . If in the question at least we could have got one exact value of either c or d , then we could find out the value of other variable.

Question<br> Write the word sentence as an inequality.<br><br> A number y is no more than −8.
vekshin1

Hey there mate ;)

As per question :-

<em>Write the word sentence as an inequality</em><em>.</em><em> </em><em>A number y is no more than −8.</em>

To make the sentence as an inequality, the answer will be:-

<h2> <u>y < -8</u></h2>

Reason:-

By considering 'y' as a number, it is told that the number is not bigger than the value -8. So, by simple arithmetic, the answer will be <em>y</em><em> </em><em><</em><em> </em><em>-8</em>

Maurinko [17]

Answer:

A = 2x²; 128 ft²  

Step-by-step explanation:

Area of original garden = x²

Let A = area of new garden. Then

      A = 2x²

If x = 8 ft,

  A = 2 × 8² = 2 × 64 = 128 ft²

The area of the new garden is 128 ft² .

Shana is climbing a mountain at a constant pace. She rises in elevation by 17.5 feet per minute. After hiking for 30 minutes, a
Mnenie [13.5K]

Answer:

The linear equation for Shana's elevation is E = 17.5\cdot t+1640.

Step-by-step explanation:

According to the statement, we find that Shana is climbing at constant rate in time and height as a function of time can be represented by linear function:

E = h_{o}+\dot h\cdot t (Eq. 1)

Where:

h_{o} - Initial height above sea level, measured in feet.

E - Elevation above sea level, measured in feet.

\dot h - Climbing rate, measured in feet per minute.

t - Time, measured in minutes.

If we know that E = 2165\,ft, \dot h = 17.5\,\frac{ft}{min} and t = 30\,s. the initial height above sea level is:

h_{o} = E - \dot h\cdot t

h_{o} = 2165\,ft-\left(17.5\,\frac{ft}{min} \right)\cdot (30\,min)

h_{o} = 1640\,ft

The linear equation for Shana's elevation is E = 17.5\cdot t+1640.
