What two ways can you find the product of 8x997 using mental math

1 answer:

7 0

8=10-2 or
997=1000-3
so we can use distributive property
remember, a(b+c)=ab+ac

for the first one
8(997)=(10-2)(997)=997(10-2)=997(10)+997(-2)=9970-1994=7976

2nd one
8(997)=8(1000-3)=8(1000)+8(-3)=8000-24=7976

How can you check the solution of an equation?

vichka [17]

In order to check you would plug in the value of x and see if it equals the same thing.
or do the opposite of the equation. it depends on if you are dealing with x or not. so if you have 6-3 is 3 you can do 3+3 is 6

The following figure is a rhombus. Find the value of m. Then, use that value to find the measure of VW

maxonik [38]

Answer:

$m=8$

The length of VW = 36 units.

Step-by-step explanation:

We know that a rhombus is a quadrilateral with four sides. All four sides have the same length.

From the diagram, it is clear that

The length of VW= 6m-12

The length of WX = 4m+4

As all the four sides of the rhombus have equal length.

So we can observe

$VW=WX$

$6m-12 = 4m+4$

Add 12 to both sides

$6m-12+12=4m+4+12$

$6m=4m+16$

$2m=16$

Divide both sides by 2

$\frac{2m}{2}=\frac{16}{2}$

$m=8$

The length of VW= 6m-12

= 6(8)-12 ∵ $m=8$

= 48-12

= 36

Thereofore, the length of VW = 36 units.
