IS (1, 2) of a solution set of x+ y = 3 and 2 x + 7 y = 16 ?

yes

Step-by-step explanation:

x=3-y

2(3-y)+7y=16

6-2y+7y=16

5y=10

y=2

x=3-2=1

In this question, it is given that

A triangle has a height of 8 feet and an area of 48 square feet.

Let the base is represented by b feet .

And the formula of area of triangle is

Substituting the given values, we will get

So the height of the triangle is 12 feet .
