Solutions

1) Subtract 7/8 from both sides
x=4−7/8

2) Simplify 4−7/8 to 25/8
x=25/8

$x + \frac{7}{8} = 4 \\ \\ x = 4 - \frac{7}{8} \\ \\ x = \frac{25}{8} \\ \\$

The final result is: x = 25/8 or x = 3.125.

Hi There!

------------------------------------------------

Slope Intercept Form: y = mx + b

Where: m = slope and b = y-intercept

------------------------------------------------

Question 11: The slope being 0.5 is the pay for the amount of miles he pays daily.

Question 12: y = 2x + 20

Question 13: y = 25x + 50

Question 14: y = 1/2x + 6

Question 15: y = 2x + 15

------------------------------------------------

Hope This Helps :)

5y(2x−3)=y(x+2)+20 where x=3

Feliz [49]

Here x=3
so, putting 3 instead of x
$5y(2(3)-3)=y(3+2)+20 \\ 5y(3)=5y+20 \\ 15y-5y=20 \\ 10y=20 \\ y=20/10=2$

jennifer bikes 7 miles south and then turns to bike 13 miles east how far away is she from where she started?

Marina CMI [18]

Answer:

She is about 14.765 miles ( $\sqrt{218}$ miles) from where she started

Step-by-step explanation:

There is a relation between the three sides of the right triangle

The side opposite to the right angle is called hypotenuse and it is the longest side

The other two sides called legs of the right angle

The relation between them is: (hypotenuse)² = (leg1)² + (leg2)²

∵ Jennifer bikes 7 miles south

∵ She turns to bike 13 miles east

∵ South and East are perpendicular

→ That means the distance from her start point to end point represents

a hypotenuse of a right triangle, whose legs are 7 and 13

∴ (hypotenuse)² = (leg1)² + (leg2)², where

hypotenuse is the distance between her start and end points

leg1 is her distance in south direction

leg2 is her distance in east direction

∵ Leg1 = 7 miles

∵ leg 2 = 13 miles

∴ (hypotenuse)² = (7)² + (13)²

∴ (hypotenuse)² = 49 + 169

∴ (hypotenuse)² = 218

→ Take √ for both sides

∴ hypotenuse = $\sqrt{218}$

∴ hypotenuse ≅ 14.76482306

∴ She is about 14.765 miles ( $\sqrt{218}$ miles) from where she started.
