A right triangle has one 90 angle.
The sum of the three angles of any triangle is equal to 180 degrees.
180-90= 90 degrees.
The answer is C.
Answer:
Step-by-step explanation:
1 quart of wax makes 6 candles
If 30 candles is to be made then 5 quart of wax is needed
The quart is made up of
2 part of red
5 parts of yellow
3 Parts of white
Total= 10 part to make the Orange shade
We knew Yellow is 5 part out of 10 part as written up
Hence, yellow will be 2.5 part in 5 quart
Answer:
x = -7
Step-by-step explanation:
This is an exponential equation.
We need to take log(or ln) of both sides and use logarithm property to solve this.
So, let's take ln of both sides, so we have:
Now, we will use this property shown below to further simplify:
So, we now have:
The value of x is -7
Answer: (0,10)
Step-by-step explanation:
Answer: (x,y) = (-1, 1)
This means that x = -1 and y = 1
========================================================
Explanation:
The first equation says that y is the same as 2x+3
That allows us to substitute y for 2x+3 in the second equation like so:
2x+5y = 3
2x+5( y ) = 3
2x + 5(2x+3) = 3 .... y replaced with 2x+3
2x+10x+15 = 3
12x+15 = 3
12x = 3-15
12x = -12
x = -12/12
x = -1
Then we'll substitute this into the first equation to find y
y = 2x+3
y = 2(-1) + 3 .... x replaced with -1
y = -2+3
y = 1
Together x = -1 and y = 1 pair up to form the ordered pair solution (x,y) = (-1,1)
If you were to graph y = 2x+3 and 2x+5y=3 on the same xy grid, then you should see that the two lines intersect at the location (-1,1). This is a visual way to determine the solution quickly through use of a graphing calculator.
