Answer:
Step-by-step explanation:
we have to get y by itself here i think
so
x + 2y = 12
2y = -x + 12
y = -1/2 + 6
7x + 2y = 0
2y = -7x
y = -3.5x
hope this helps <3
For this problem,all we have to do is translate the word problem into algebraic equations. The equations are as follows:
L = √100 * x = 10x
W = 1/2*y - 3/2*x
Since A is equal to length times width
A = LW
If L is given, we can find the x. Therefore, we must set the equation where the dependent variable is y and the independent variable is x.
125 = LW
W = 125/L
1/2*y - 3/2*x = 125/10x
10x(1/2*y - 3/2*x) = 125
5xy - 15x² = 125
xy - 3x² = 25
y = (25+3x²)/x
<em>y = 25/x + 3x</em>
For the base u could use 10 and the height 4 becuz the area of a triangle is .5bh
What I do in my school is Part over a Whole equals % over 100.
So the whole is 80, the percent is 80% over 100. We need to find the part so we cross multiply. 80×80% is 1600. Divide that by 100 and u get 16 points.
HOPE THAT HELPS!
