Answer:
Malik substituted 60 for y instead of x
Step-by-step explanation:
<u><em>The complete question is</em></u>
Malik’s solution to the equation ,2/5x-4y=10 when x=60, is shown below.what error did Malik make first when solving the equation ?
Options are
malik did not multiply correctly. malik added 240 to each side of the equation. malik did not multiply correctly. malik substituted 60 for y instead of x
<u>Malik’s solution is</u>
we have
For x=60
substitute the value of x in the equation and solve for y
therefore
Malik substituted 60 for y instead of x
I believe the answer is D.
Answer:
dang nice
Step-by-step explanation:
Consider a trapezoid GJKF with:
GH=JH (hypothesis)
FL=KL (hypothesis)
so HL is the median of trapezoid GJKF
so: HL=1/2(2.5+1.2)=1.85
Height x base is the formula for parallelogram
5.25 x 12 = 63
