Given:
The actual length of side y is 22cm.
To find:
The length of side x by using the scale drawing.
Solution:
We know that the corresponding sides of original figure and scale drawing are proportional.
Therefore, the length of side x is about 28.286 cm.
Answer: -10, 10
Step-by-step explanation:
first lets add the two equations. add the x's, add the y's, add the constants on the right.
we get
0x - 1y = -10
so then divide --10 by -1 because we do the opposite operations to both sides
and we get y = 10
now substitute y = 10 into the first equation
-10x - 9(10) = 10
and then we get -10x - 90 = 10
now add 90 to both sides
-10x = 100
divide 100 by -10
x = -10
y = 10
checks out
EPIC. STAY EPIC AND AWESOME FRIEND.
kilometers and miles are units used to measure distance.
1 mile is equal to 1.61 km
so if 1 mile is equivalent to 1.61 km
then to see how many kilometers are there in 50 miles we have to multiply 50 miles by 1.61 km/mile
therefore the number of km in miles is - 50 miles x 1.61 km/mile = 80.5 km
distance in km - 80.5 km
Keep your mom, you only have one. But anyway;
Use the Pythagorean Theorem: A^2 + B^2 = C^2
12^2 + 21^2 = C^2
144 + 441 = C^2
585 = C^2
square root of 585 = approximately 24.2
