Answer:

X = 2

Step-by-step explanation:

From the question we can gather some pretty important information. For starters, "three times a number x" would give us 3x. Secondly, "increased by 4" would give us +4. Lastly, "equal to five times x" would be = 5x. If we put this all together we have the following Algebraic Equation.

$3x+4 = 5x$

Now we can start solving the equation.

$3x+4 = 5x$

$4 = 2x$

$2 = x$

So we can see that the value of x in this equation is 2.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

3x+4=5x
4=5x-3x
4=2x
X=2

Someone pls help me I'm really struggling and the assignment is almost due

Answer:

x<3 and x≥5

Step-by-step explanation:

Look at the circles and what is shaded on the number line. The first circle is at x=3, and it's an open circle. An open circle means that the interval does not include that point. The arrow is going to the left, meaning x < 3.

The next circle is at x=5. It is a closed circle, so the interval does include that point (so draw a bar under the less than/greater than sign). Next, notice how the arrow is pointing to the right. That means that the blue area is at x=5 and greater than x=5, so x≥5.

Answer:

238 cm

Step-by-step explanation:

so we have a scale factor of 17: 1

originally we had the dimensions: 3cm by 4m

now we have 3*17 by 4*17 = 51 cm by 68 cm

Perimeter = 2*51 + 2*68 = 238 cm
