Step-by-step explanation:
<em>it is a right angle triangle</em>
30square =14square +x square
900=196+xsquare
900-196=xsquare
704=xsquare
root704=x
26.532=x
90+26.532=63.468
180-63.468=116.532degree
C cheap is considered a pretty bad word
Answer:
c
Step-by-step explanation:
system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. ... The solution to the system will be in the point where the two lines intersect.
Answer:
Multiply the second equation by 2
Step-by-step explanation:
Given
Required
Get matching coefficient for elimination
The coefficient of x in both expressions are factors.
So, we can multiply the second equation by 2 to get the coefficient of x in the first.
i.e.
So, the system becomes:
<em>Now, x can be eliminated</em>
Mass = density x volume
Mass = 3.5 x 20 = 70 grams
