He spoke to each friends for 26 minutes

How I found out : how I found out is that all you have to do it get the total amount which in this question it is going to be 182. And you would need to dive 182 by 7 to find the unit rate (182/7) which is going to equal 26.which means he called each friend for 26 minutes

So the formula for the area of a triangle is $A=\frac{1}{2} bh$ (b = base, h = height). In this case, by counting from (-3,-3) to (-3,2) the height is 5 and the base is 4 counting from (-3,2) to (1,2).

Using this info, we can form the equation $A=\frac{1}{2} *4*5$ and solve from there.

$A=\frac{1}{2} *4*5\\ A=\frac{1}{2} *20\\ A=10$

Answer: The required equation is $x=(7\times12-34.5)\div8\frac{1}{4}$

Maria can cut 6 sections from the remaining rope.

Step-by-step explanation:

The total length of rope = 7 feet

since 1 feet = 12 inches

Therefore, 7 feet= $7\times 12=84\ inches$

Let x be the number of sections.

Since the instructions are to use 34.5 inches of rope to tie a tarp on top the the tent. Then, the remaining rope should be cut 8 1/4 inch sections to tie tent to stakes in the ground.

then the required equation will be

$x=(7\times12-34.5)\div8\frac{1}{4}\\\Rightarrow\ x=(84-34.5)\div \frac{33}{4}\\\Rightarrow\ x=49.5\div8.25\\\Rightarrow\ x=6$

So, maria can cut 6 sections.
