Answer:

Step-by-step explanation:

The math question is asking you to solve for t. In other words, your objective is to keep the t in one side of the equal sign, usually the left side, and move everything else to the other side, right side. This is your objective.

Step 1. Write out what you have, in this case and equation

16-2t=5t+9

In this case, it is better to move the t's on the right side of the equal sign.

16(2t-2t)=5t+9-2t ===> 16=(5t+2t)+9 ===> 16=7t+9

Once you have the t on one side of the equation, move the rest of the stuff, in this case, a whole number t othe other side of the equation.

16-19=7t+(9-9) ===> -3=7t+(0) ===>-3=7t

Your almost done. Next, divide boths sides by 7 in order to get t by itself.

-3=7t ===> -(3/7)=(7/7)t ===> -3/7=t

So, your answer is t= -3/7

TIP: Remember to show your work so that if you ever get the answer wrong, you can always go back to check your steps for any errors you may have made

Answer:

1 = t

Step-by-step explanation:

add 2t to both sides which will leave you with 16 = 7t + 9 then you subtract 9 from both sides which leaves you with 7 = 7t so after that your going to divide by 7 on each side and you should have 1 = t

Which is the equation of a line that has a slope of -2/3 and passes through point (-3, -1)? y=-2/3x+1.

bazaltina [42]

Answer:

y = -2/3x - 3

Step-by-step explanation:

First, write the equation using the slope. It should look like this: y = -2/3x + b. Next, find the y intercept by plugging in the point. This is what it looks like: -1 = -2/3(-3) + b. Multiply -2/3 by -3 to get 2. This is what it should look like now: -1 = 2 + b. Subtract 3 from both sides to get -3 = b. Go back to your original equation and plug in -3 for b. This is your final equation:

y = -2/3x - 3

Hey, there, Brooklyn! For the first problem, set up a proportion. Think of the line that separates the numerator and denominator is the word 'per'. If it's 0.75 yd per costume, then your fraction is $\frac{0.75(yards)}{1(costume)}$ . If she buys 6 yards, simply multiply $6 * 0.75$ , which is 4.5. However, making 4.5 costumes doesn't sound too possible, does it? It's better to just say she can make 4 costumes.

Now let's look at the second problem. If just one side has a length of $(4x - 2y)$ , then that means there must be another side with the same length, as it is a rectangle we're talking about here. That means we should multiply the known length by two and subtract it from the perimeter like this:

$12x + 8y - 2(4x - 2y)$

Remember the PEMDAS method. Distribute the 2;

$12x + 8y - 8x + 4y$

Now combine like terms: $12x - 8x + 8y + 4y$

--> 6x + 12y

Now we have an answer, but it's not the right one. You see, this is the length of both of the unknown lengths. To get the right answer, divide this by 2. The other side is $3x + 6y$ units long. Hope this helped.
