Answer: 2.5 cm


Step-by-step explanation:

We know that area of trapezoid A = \frac{1}{2}h(a+b), where a and b are the opposite sides of trapezoid and h is the altitude of the trapezoid.

Given: AB = 1 cm and  CD = 5 cm, and the area = 7.5 square cm.

By the name of trapezoid we can see that AB and CD are opposite sides of trapezoid, then

Area of trapezoid=\frac{1}{2}h(AB+CD)=7.5\ cm^2

\Rightarroe\frac{1}{2}h(1+5)=7.5\\\Rightarrow\ h(6)=2\times7.5\\\Rightarrow\ h=\frac{2\times7.5}{6}\\\Rightarrow\ h=2.5

Hence, the altitude of the trapezoid = 2.5 cm

Area of a trapezoid = 1/(a + b)h; where a and b are the two parallel sides and h is the height (altitude).
7.5 = 1/2(1 + 5)h = 1/2(6)h = 3h
h = 7.5/3 = 2.5 cm.

Answer:

x=1

Step-by-step explanation:

you would substitute the first equation in for the y in the second equation

x + 2x+3 =6

then you would combine the x's

3x +3 = 6

Then you would move the 3 to the other side with the six

3x =6-3       3x = 3

Then finally you would divide the three

3x/3 = 3/3   x=1
