1) Convert kilograms to grams : 1 kilogram = 1000 grams
2) Divide 1000 by 50 to see how many packets of pasta are in 1 box : 1000 divided by 50 is 20
3) 20 x 2(it's two boxes), which is 40
Therefore, there are 40 packets of pasta in 2 boxes
I dont know why didnt you pay attention
X+y=50
x-y=12
add the equations:
2x=62
x=31
50-31=19
(31-19=12 just to verify)
31^2 - 19^2 = 600
Answer:
$9
Step-by-step explanation:
Let's make the price of toilet paper x, and the clorox wipes y. We can then use the given information to create a system of equations.
Our equations are 2x+4y=36 (because 2 packs of toilet paper and 4 containers of Clorox wipes cost $46) and x+3y=27 (because 1 pack of toilet paper and 3 containers of Clorox wipes cost $27). Now, let's solve!
2x+4y=36 (1)
x+3y=27 (2)
2x+6y=54 (3) (i just mutiplied (2) by 2 so that i could eliminate x)
2y=18 (3)-(1)
y= $9/pack

Proof:
In
,
is an altitude drawn from C to
.
It means,
are right angle triangles.
In

Leg :
[Common]
If the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then by HL postulate both triangles are congruent.
