Solve the equation for x. Round your answer to the nearest hundredth 8(x-7)=454

Answers

Answer 1

Answer:

Answer: 63.75 or 225/4

I just did it on an IT Inspired inspired Calculator to solve for X and 63.75

Answer 2

Answer:

Step-by-step explanation:

8(x - 7) = 454

x - 7 = 454/8

x - 7 = 57

x = 57 + 7

x = 64

Which is the answer 3.6÷3 and how can solve?

Answers

Answer: 1.2

Why? Here:

3.6 is also known as 36/100

So, 36/100 ÷ 3/1

36/100 x 1/3 ( transposing because of divide)

36 comes in 3 table so, 36÷3 is 12

12/100 x 1

12/100 also known as 1.2

the vertices of a triangle at A(5,-4) ,B(7,0) ,and C(1,-2). if the triangle is a right triangle, which vertex is the right angle

Answers

We can find the right angle of the triangle by finding the slope of the sides .

Any right angle makes an angle of 90 degrees and the lines are perpendicular .

For perpendicular lines product of slopes is -1.

In other words the slopes have opposite signs and are reciprocal .

Let us find the slopes of AB,BC,CA.

Slope of two points can be found by the difference in y values divided by different in x values

Slope of AB= $(0+4)/(7-5) =(4)/(2) =2$

Slope of BC= $(-2-0)/(1-7) =(-2)/(-6) = 3$

Slope of CA= $(-2+4)/(1-5) =(2)/(-4) =(-1)/(2)$

The slopes of AB and CA are reciprocal of each other with opposite signs or we can say their product is -1 so they are perpendicular.

Angle A is the common angle to these sides so we say angle A is the right angle

Which is a better deal 48 oz for $6 or 4 lbs for $12? Please answer its urgent!!!!

Answers

Hi Kaiden!

So to answer the question, we'll first need to understand the conversion from ounces to pounds. In the U.S.A., 1 lb (pound) is the same as 16 oz (ounces). To approach this problem, we can either convert pounds to ounces or ounces to pounds, in order to better compare the two prices we're given. For this problem, let's convert the 4 lbs to oz.

We know that 1 lb = 16 oz so using multiplication, we can find that 4 lbs is:
⇒ 4 × 16 oz = 64 oz.

Let's look at the problem again. We now see that the deal is either 48 oz for $6.00 OR 64 oz for $12.00. If we take the first part of the deal, 48 oz for $6.00, and multiply everything by 2, we can further see that the deal is now:
96 oz for $12.00 OR 64 oz for $12.00. We can now see that we get more quantity with the first deal.

-Hope this helps!

Well, right now we would have to convert.
So there are 16 ounces inn 1 pound.
First we would have to multiply 16 times 4 to see how many ounces.
16 times 4 = 64 ounces.
Now let's see how many POUNDS is 48 ounces.
We would have to divide 48 by 16, which is 3, so it would be 3 pounds.
Now we would have to find the unit rate of both sides.
So we would do 12 divided by 4 which equals 3, so it's $3 for every pound.
Now we must find the unit rate of the other given option.
We'll do 6 divided by 3, (because 48 ounces is equivalent to 3 pounds),
and that'll be 2, so it's $2 for every pound.
Now, we'll have to go with the cheaper option, because it'll be the better deal, and that deal is.....................
48 oz for $6.
I hope I helped, and PLEASE choose my answer as the Brainliest!
