Answer:

x=5

Step-by-step explanation:

natima [27]3 years ago
4 0

Subtract 6 from both sides

-3x = -9 - 6

Simplify -9 - 6 to -15

-3x = -15

Divide both sides by -3

x = -15/-3

Two negatives make a positive

x = 15/3

Simplify 15/3 to 5

<u>x = 5</u>

The total amount of money (in cents) in x nickels, (x+5) dimes and 2x quarters
Scorpion4ik [409]

\\&#10;\text{Suppose you have x nickels, (x+5) dimes and 2x quarters}\\&#10;\\&#10;\text{we know that the value of 1 quarter is}=\$ 0.25=\text{ 25 cents}\\&#10;\\&#10;\text{value of 1 dime}=\$0.10=10 \text{ cents}\\&#10;\\&#10;\text{value of 1 Nickel}=\$ 0.05=5 \text{ cents}\\&#10;\\&#10;\text{so the total amount of money in cents is}\\&#10;\\&#10;=5(x)+10(x+5)+25(2x)\\&#10;\\&#10;=5x+10x+50+50x\\&#10;\\&#10;=65x+50

So the total amount of money is: (65 x +50 ) cents

A backyard pool has a concrete walkway around it that is 5' wide on all sides the total area of the pool and the walkway is 950'
Soloha48 [4]

The dimensions of the pool would give a quadratic equation x² + 28x - 770 = 0

<h3>How to determine the dimension</h3>

For the pool, we have that;

Let the width = x feet

Length = (x+8) feet

The pool alongside the walkway gives;

Width = x + 5 + 5 = (x + 10) feet

Length = x + 8 + 5 + 5 = (x + 18) feet

Total area of the pool with walkway = 950 square feet

Note that formula for area is given as

Area = length * width = 950

Equate the length and width

(x+18)  × (x + 10) = 950

Using the  FOIL method, we have;

(x × x )+ (x × 10) + (18 × x) + (18 × 10) = 950

x² + 10x + 18x + 180 -950 = 0  

collect like terms

x² + 28x - 770 = 0

Thus, the dimensions of the pool would give a quadratic equation x² + 28x - 770 = 0
