Answer:

-11

Step-by-step explanation:

First get x alone.

Subtract 16 from both sides: -12 = 3x

Divide both sides by 3: -4 = x

Plug in x: -4 - 7 = -11

4=3x+16

4-16= -12

-12=3x

We then divide the -12 by 3 and the 3x by 3. -12 divided by 3 is -4.

-4 minus 7 (or -4-7) equals -11.

The final equation is -4-7=-11
The final answer is -11.

A regular triangular pyramid with a slant height of 9 m has a volume equal to 50 m^3. find the lateral area of the pyramid

Cerrena [4.2K]

we are given a regular triangular pyramid with a slant height of 9 m and volume of 50 m3. We can get the altitude of the pyramid by sin 60 = h / 9; h is equal to 7.7942 m. Volume is equal to 1/3 h * B, B is equal to 19.2451 m2. perimeter of the base is 3*9 m equal to 27 meters. The lateral area has a formula of 1/2 pl, substituting, lateral area is equal to 121.5 m2.

You open a book to two facing pages. The product of the two pages is 600. Find the page numbers.

Ivan

To find this, use an equation with x to represent the smaller page number as your variable. set up the equation x(x+1) = 600. distribute the x to get x^2 + x = 600. subtract 600 from both sides so you have x^2 + x - 600 = 0. factor to get (x+24)*(x+25) = 0. so the two pages are 24 and 25

Math question.......................................

ValentinkaMS [17]

Question 1:

The answer is A: Sam.

His table is the only one that follows the conditions set in the question.

Question 2:

Choosing two points; (0, 14) and (4, 10)

Slope (m) = $\frac{10 - 14}{4 - 0} = \frac{-4}{4}$ = -1

Thus, equation,

$y - y_{1} = m(x - x_{1})$

$y - 10 = -1(x - 4)$

$y = -x + 14$

I'm getting that for my equation of the line, so my best guess is that the answer is C.

The reason I got my answer is probably because I made a calculation mistake somewhere. If you use my methods, you should arrive at the correct answer.

The answer is C. ( I believe )

Hello! Sorry about your luck before although im 99% sure my answer is correct.

Answer: area is 180

Step-by-step explanation:

Ok so first starting off im going to calculate the area for each shape serperately and add them up since thats easier so as demonstrated in the picture the rectangle is 25 because i multiply by base × height and the base and height is 5 and 5 pointed in the picture so thats 25 although i didnt calculate the rest because the base and height is the same for each so we can just do 25 × 6 to get all the rectangles so 25 × 6 = 150 now we got the easy part out of the way now we should do the triangles I pointed to the base and height for that on the left the base being 5 and the height being 3 5 × 3 = 15 BUT WAIT this isn't are area for the triangles because when finding area for triangles we have to divide by 2 so... 15 ÷ 2 = 7.5 since there are 4 of those triangles I dont have to solve for the rest because i can just do 7.5 × 4 so...

7.5 × 4 = 30 now we just combine those areas together! so... 150 + 30 = 180 so 180 is our area HOPE THAT HELPS!
