You weld two piece's of steel together. The toral thickness is 33/64 inch. If one piece of steel is 9/32 inch thick, how thick t

Anon25 [30]

Subtract the thickness of the known piece from the total thickness.

Because they have different denominators rewrite them to have the same.

9/32 x 2 = 18/64

Now you have 33/64 - 18/64 = 15/64

The other piece is 15/64 inch thick.

52 998 x 67 = (1,000 - 998) x 67

Tresset [83]

Given:

$\to \bold{52,998 \times 67 = (1,000 - 998) \times 67}$

To find:

Proving

Solution:

$\to \bold{52,998 \times 67 = (1,000 - 998) \times 67}$

Solving L.H.S part:

$\to \bold{52,998 \times 67}\\\\\to \bold{3,550,866}\\\\$

Solving R.H.S part:

$\to \bold{(1,000 -998) \times 67}\\\\\to \bold{(2) \times 67}\\\\\to \bold{ 134 }\\\\$

Therefore $\bold{L.H.S \bold{\neq} R.H.S}$

3 /10 = 9 /k what is k

NemiM [27]

In order to isolate k, we would first cross multiply
3*k=9*10
3k=90

Then to isolate k, we would divide both sides by 3 to get:
K=30
