4t + 2 = 7t - 7 What is t?

Mathematics

Hey!

Here is the equation:

4t + 2 = 7t - 7

Subtract 4t from both sides. It becomes:

2 = 3t - 7

Add 7 to both sides. It becomes:

9 = 3t

Divide both sides by 3 to leave t alone. It becomes:

\frac{9}{3} = \frac{3t}{3} \\ t = 3

That means t is equal to 3.

<em>Good luck and hope this helps!</em>

To solve this question, we want to get t by itself, on one side. To do that, the first step is the get all terms with 't' on one side and all the constants (numbers) on the other side.

4t + 2 = 7 t - 7

Since the left side has a greater number of t, let's move all of the terms with t there.

4t - 4t + 2 = 7t - 4t - 7

2 = 3t - 7

Now we move the numbers

2 + 7 = 3t - 7 + 7

3t = 9

Now we get t by itself.

3/3t = 9/3

t = 3

What is the slope of a line that is parallel to the line y=3/4x+2
stepladder [879]
If two lines are parallel to one another, then their slopes are identical.  The slope in the line above is 3/4.  Therefore, a line parallel to that line will also have a slope of 3/4, it will just have a different y-intercept.

What is the vertex of the quadratic function f(x)=(x-8)(x-2)?
7nadin3 [17]
Change the function into vertex form:
f(x)=x²-10x+16
make a square by (adding half of -10)², which is 25, then subtract it:
f(x)=x²-10x+25-25+16
f(x)=(x-5)²-9
so the vertex is at (5,-9)

another way to do it: 
f(x)=x²-10x+16
the vertex is when x=-\frac{b}{2a}, b=-10, a=1 in this case.
x=-(-10/2*1)=5
plug x=5 into the quadratic function, you get f(x)=-9

The dimensions of a room are 4.2m by 6m. On a plan, the longer side is equal to 4 cm. What is the length of the shorter side on
Fiesta28 [93]

Answer: Length of shorter side is 2.8 cm.

Explanation:

Since we have given that

Dimensions of a room are given by

4.2\ m\times 6\ m

On a plan,  the longer side = 4 cm

As we know that the ratio of original room is equal to ratio of plan room

So,

\frac{4.2}{6}=\frac{x}{4}\\\\4.2\times 4=6x\\\\16.8=6x\\\\\frac{16.8}{6}=x\\\\2.8=x

So, length of shorter side is 2.8 cm.
