Add 6x and x to have 7x.
-1+6x+x=-1
7x-1=-1
+1=+1
7x=0

Divide 7x by 7 so the x can be left alone.

X=0

First you combine the x. 6x+(1)x = 7x
-1+7x=-1

Then move the -1 to the other side, changing the sign( if it is positive make it negative. If it is negative make it positive) -1+1 = 0
7x=0

Next you divide the 7 by 0 because you undo the multiplication ( the opposite of multiplication is division) 7/0 = 0
x=0

Hope this helps!!❤️

Three friends Kofi,Yaw and Musa are in partnership business in which Kofi and Yaw contributed 5/9 and 2/15 of the cost of 14000.

Answer:

(a) $Total = 45000$

(b) Yaw, Musa and Kofi

Step-by-step explanation:

Given

$Kofi =5/9$

$Yaw = 2/15$

$Musa = 14000$

Solving (a): The cost of the business

First, we solve for the fraction of Musa

$Musa + Kofi + Yaw = 1$

$Musa = 1 - (Kofi + Yaw )$

$Musa = 1 - (5/9 + 2/15)$

$Musa = 1 - (\frac{25+6}{45})$

$Musa = 1 - \frac{31}{45}$

$Musa = \frac{45 - 31}{45}$

$Musa = \frac{14}{45}$

So, we have:

$\frac{14}{45} * Total = 14000$

Make Total the subject

$Total = 14000 * \frac{45}{14}$

$Total = 1000 * 45$

$Total = 45000$

Solving (b): Partners in ascending order

First, represent the fractions as decimals

$Kofi =5/9$ $= 0.5556$

$Yaw = 2/15$ $= 0.1333$

$Musa = \frac{14}{45}$ $= 0.3111$

From the conversion above, the least is 0.1333 (Yaw), then 0.3111 (Musa), then 0.5556 (Kofi).

<em>So, the order is: Yaw, Musa and Kofi</em>

Your uncle won the powerball jack[ot and decided to give you 50000 dollars. You want to save this money for college so you find

Ahat [919]

Answer: $58,088.57

Step-by-step explanation:

The investment is compounded weekly so you need to change the parameters of the equation to a weekly figure:

Interest rate is yearly so:

= 3.75%/52

= 3.75/52% per week

Number of periods is 4 years so:

= 4 * 52

= 208 weeks

Future value in 4 years is:

= 50,000 * ( 1 + 3.75/52%)²⁰⁸

= $58,088.57
