Answer:

$y=1.94x$

13 glue sticks cost $25.22.

Step-by-step explanation:

4 blue sticks cost $7.76, this means that one glue stick costs

$7.76/4 = $1.94.

Let $y$ be the cost of the glue sticks, and $x$ be the number of glue sticks; then

$\boxed{y=1.94x}$

We can use this equation to find the cost of 13 glue sticks; we just put $x=13\$ into our equation and it gives:

$y=1.94(13)=25.22$

So 13 glue sticks cost $25.22.

Answer:

PA GEN SOLISYON --> "NO SOLUTION"

Step-by-step explanation:

Whether you multiply the top equation by ⅓ to make "-y" and "2x", or multiply the bottom equation by 3 to make "3y" and "-6x", you will see that 9⅓ ≠ 0, or 24 ≠ 0, therefore the result is "NO SOLUTION".

55. The sum of an infinite geometric series is five times the value of the first term. What is the common ratio of the series?

myrzilka [38]

Answer:

r = 4/5

Step-by-step explanation:

Formula

Sum of an infinite geometric series = a / (1 - r)

Givens

Sum = 5*a

a = a

r = ?

Solution

5a = a/(1 - r) Divide both sides by a

5a/a = a / (a * (1 - r) The a's on the right cancel

5 = 1 / (1 - r) Multiply both sides by 1 - r

5*(1 - r) = 1*(1 - r)/(1 - r) The 1 - r s on the right cancel

5*(1 - r) = 1 Remove the brackets.

5 - 5r = 1 Subtract 5 from both sides

5-5 - 5r = 1 - 5 Combine

-5r = - 4 Divide by - 5

r = 4/5

Answer:

Given expression : $\frac{9}{4}-2(4x+\frac{4}{3} )+\frac{5}{2}x$ ......[1]

Using distributive property: $a\cdot (b+c) =a\cdot b + a\cdot c$

[1]⇒ $\frac{9}{4} - 2(4x) - 2(\frac{4}{3})+\frac{5}{2} x$

Simplify:

$\frac{9}{4} - 8x - \frac{8}{3}+\frac{5}{2}x$

Like terms are those terms which are same variables.

Combine like terms: we get;

$(\frac{9}{4} - \frac{8}{3}) - 8x + \frac{5}{2}x$ ......[2]

$\frac{27-32}{12} -8x +\frac{5}{2} x$

Simplify:

$\frac{-5}{12} -8x +\frac{5}{2}x$

$\frac{-5}{12} - \frac{11}{2}x$

we can write equation [2] as;

$\frac{27}{12} - \frac{8}{3} - 8x + \frac{5}{2}x$

Combine like terms of x variables;

$\frac{27}{12} - \frac{8}{3} - \frac{11}{2}x$

Therefore, the expressions which are equivalent to the Given expression are:

$\frac{9}{4} - 2(4x) - 2(\frac{4}{3})+\frac{5}{2} x$

$\frac{-5}{12} -8x +\frac{5}{2}x$

$\frac{27}{12} - \frac{8}{3} - \frac{11}{2}x$

$\frac{-11}{2}x - \frac{5}{2}$
