Answer:

I am not sure how your teacher wanted you to estimate the answer but I solved it for you. Hopefully this helps.

Step-by-step explanation:

7x-y=7

x+2y=6

14x-2y=14

x+2y=6

add both equations

15x=20

x=20/15

x=4/3

x+2y=6

4/3+2y=6

2y=6-4/3

2y=18/3 -4/3

2y=14/3

divide both sides by 2

y= 14/3 divided by 2

y=14/3(1/2)

y=14/6

2y=

Andrei [34K]

Answer:

$m\angle AED=116\degree$

Step-by-step explanation:

By intersecting chords theorem:

$m\angle AED=\frac{1}{2} (92+140)\degree$

$m\angle AED=\frac{1}{2} \times 232\degree$

$m\angle AED=116\degree$

3x-7y=14

Mademuasel [1]

Answer:

A. $\frac{3}{7}$

Step-by-step explanation:

The given equation is

$3x-7y=14$

We solve for y by subtracting 3x from both sides to obtain;

$-7y=14-3x$

We now divide through by -7 to get;

$y=\frac{-3}{-7}x+\frac{14}{-7}$

This simplifies to;

$y=\frac{3}{7}x-2$

This equation is now in the form y=mx +c, where $m=\frac{3}{7}$ is the slope.

pentagon [3]

we are given

total number of apples =54

Let's assume each friend receives =x

He kept a apples for himself and gave each of 6 friends an equal number of apples

so, we will get equation as

$6x=54$

now, we can solve for x

$x=9$

each friend receives is 9 apples.........Answer
