What is the solution of the following equation? 2x-5+3x=35

harina [27]

2x - 5 + 3x = 35 

simplify 

5x - 5 = 35 

add 5 to both sides 

5x - 5 + 5 = 35 + 5 

simplify 

5x = 40 

divide both sides by 5 

5x/5 = 40/5 

simplify 

x = 8

A food processor for $149.50 cash, or $5.00 down and $10.00 per month for 15 months

ddd [48]

Answer:

Difference in cash and plan = $155 - $149.50 = $5.50

Interest Rate = 3.68%

Step-by-step explanation:

Given:A food processor for $149.50 cash, or $5.00 down and $10.00 per month for 15 months

A food processor by cash = $149.50

Payment plan = Down payment + $10*15 months

= $5 + $10*15

= $5 + $150

Payment plan = $155

Difference in cash and plan = $155 - $149.50 = $5.50

Now we have to find the interest rate

= (difference/original)*100

= (5.50/149.50)*100

Interest Rate = 3.68%

If p is inversely proportional to the square of q, and p is 25 when q is 3, determine p

ArbitrLikvidat [17]

Answer:

p = 9 when q = 5.

Step-by-step explanation:

p is inversely proportional to the square of q

This means that:

$p = \frac{k}{q^2}$

In which k is a constant multiplier.

p is 25 when q is 3

We use this to find k.

$p = \frac{k}{q^2}$

$25 = \frac{k}{3^2}$

$k = 25*9 = 225$

$p = \frac{225}{q^2}$

Determine p when q is equal to 5.

$p = \frac{225}{q^2} = \frac{225}{5^2} = 9$

p = 9 when q = 5.

Hi, umm pls help 1/6(x-5)=1/2(x+6), solve for x And can you please explain

Mumz [18]

Answer:

By solving the equation $\frac{1}{6}(x-5)=\frac{1}{2}(x+6)$ we found that $x=\frac{23}{2} \text { or }=11 \frac{1}{2}$

Explanation:

Given equation,

$\frac{1}{6}(x-5)=\frac{1}{2}(x+6)$ to find x

Step: 1 Cross multiply the denominators 2(x-5)=6(x+6)

Step: 2 Open brackets and simplify the term 2x-10=6x+36

Step: 3 Bring x terms on one side and simplify the equation the equation obtained is following,

2x-6x=36+10

-4x=46

$-x=\frac{46}{4}=\frac{23}{2}=11 \frac{1}{2}$

Therefore, we solved x value from the given equation $\frac{1}{6}(x-5)=\frac{1}{2}(x+6)$ as $x=\frac{23}{2} \text { or }=11 \frac{1}{2}$ .
