Answer:

-7x -2 = 24 -9x

+9x = +9x Add 9x both side to bring the like terms together

2x - 2 = 24

+2 = +2 Add 2 both side to isolate the variable

2x = 26 Divide both side by 2, to get the value of x

x = 13

What is the value of triangle in the equation shown? 8 x 4 = (triangle x 7) - (triangle x 3)

GarryVolchara [31]

9514 1404 393

Answer:

triangle = 8

Step-by-step explanation:

The right side can be factored so that you have ...

8 x 4 = (triangle x 7) - (triangle x 3)

8 x 4 = triangle x (7 - 3) . . . . use the distributive property

8 x 4 = triangle x 4 . . . . . . simplify

8 = triangle . . . . . . . . . . divide both sides by 4

Pyramid A is a square pyramid with a base side length of 7 inches and a height of 6 inches. Pyramid B has a volume of 3,136 in?.

anygoal [31]

Answer:

WE HAVE FIND HOW MUCH MAY TIME BIGGER IS THE VOLUME OF PYRAMID B THAN PYRAMID A.

The answer is 32 times

Step-by-step explanation:

Volume of Pyramid B = 3136 in³

Volume of Pyramid A = ?

We have to find volume of Pyramid A. As Pyramid is a square pyramid, its volume is given as:

$V=\frac{(b^2)(h)}{3}$

where b = base = 7 and h = height = 6. Substitute the values:

$V=\frac{7^2\cdot6}{3}\\V=98\\$

Volume of Pyramid A = 98 in³

To find how many time B is bigger than A, divide volume of B by A:

$\frac{3136}{98}=32$

So, volume of Pyramid B is 32 times bigger than volume of Pyramid A
