Nolan has some nickels and some dimes. He has no more than 19 coins worth no less than $1.30 combined. If Nolan has 5 nickels, d

Allushta [10]

Answer:

number of dimes 11 to 14

Step-by-step explanation:

given data

coin = 19

worth no less = $1.30

Nolan nickles = 5

solution

we convert 5 cent to dollars, it will be

5÷100 = $0.05

and

dime is worth 10 cents

so it will be 10 ÷ 100 = $0.1

so we consider here x as the number when nickels.

and we consider y as the number of dimes.

so here we can say

x + y ≤ 19 ..........................1

as here no less than $1.30 combined.

0.05 x + 0.1 y ≥ 1.3 ......................2

and

when Nolan has 5 nickels

put x = 5 in eq 1

5 + y ≤ 19

y ≤ 19 - 5

y ≤ 14

and

now we put x = 5 in eq 2

0.05 × 5 + 0.1y ≥ 1.3

0.25 + 0.1y ≥ 1.3

0.1y ≥ 1.3 - 0.25

0.1y ≥ 1.05

y ≥ 10.5

so all possible values for the number of dimes 11 to 14

As per the problem

The chemicals in my swimming pool use a ratio of 5 tablets of chlorine for every 14 days.

we have been asked to find

Which ratio shows the number of chlorine tablets needed for 42 days?

Since for each 14 days the number of tablets required is 5

So if you multiply the number of days by some number then, we will have to multiply the number of tablets required by the same number.

So When number of days $=14*3=42\\$

Then the number of tablets required for 42 days is $=5*3=15\\$

What is the answer to 3/x=-3/3x+5

Aleonysh [2.5K]

Answer:

$-\frac{5}{4} =x$

Step-by-step explanation:

We first need to bring x up into the numerator. I will find common denominators by multiplying both sides by each denominator.

$\frac{x(3x+5)}{1} *\frac{3}{x} =\frac{-3}{3x+5}*\frac{x(3x+5)}{1}$

This will eliminate both denominators and leave me with

$(3x+5)3=-3(x)\\9x+15=-3x$ after I simplify the parenthesis.

Now I will solve the equation for x by subtracting 9x from both sides.

$9x-9x+15=-3x-9x\\15=-12x$

Then divide by the coefficient of x.

$\frac{15}{-12}=\frac{-12x}{-12}$

$-\frac{5}{4} =x$
