Archy [21]

How many times does 5 go into 29? It can go into it 5 times which equals 25. Now what's 29 - 25? 4 is the answer then you see how many times can 5 go into 4, well it can't so then you bring the number 0 to make it 40. Now how many times can 5 go into 40? It can go into 40 eight times since 8x5=40 so the answer is 58

??????????????????????????????

Greeley [361]

$\large\displaystyle\text{$\begin{gathered}\sf \frac{2x-20}{3}=2x \end{gathered}$}$

Multiply both sides of the equation by 3.

$\large\displaystyle\text{$\begin{gathered}\sf 2x-20=6x \end{gathered}$}$

Subtract 6x on both sides.

$\large\displaystyle\text{$\begin{gathered}\sf 2x-20-6x=0 \end{gathered}$}$

Combine 2x and −6x to get −4x.

$\large\displaystyle\text{$\begin{gathered}\sf -4x-20=0 \end{gathered}$}$

Add 20 to both sides. Any value plus zero results in its same value.

$\large\displaystyle\text{$\begin{gathered}\sf -4x=20 \end{gathered}$}$

Divide both sides by −4.

$\large\displaystyle\text{$\begin{gathered}\sf x=\frac{20}{-4} \end{gathered}$}$

Divide 20 by −4 to get −5.

$\large\displaystyle\text{$\begin{gathered}\sf x=-5 \ \ \to \ \ \ Answer \end{gathered}$}$

A store allows customers to fill their own bags of candy. Troy decides he only wants chocolate-covered pretzels and gumdrops. Ch

kobusy [5.1K]

Answer: He bought 0.5 pounds of chocolate-covered pretzels and 1.3 pounds of gumdrops.

Step-by-step explanation:

Let Troy bought x pounds of chocolate-covered pretzels and y pounds of gumdrops.

Since, the total pounds he bought = 1.8 pounds,

That is, x + y = 1.8 ------------(1)

Also, he total spent total 1.29 dollars in which Chocolate-covered pretzels sell for $0.89 per pound, and gumdrops sell for $0.65 per pound.

That is, 0.89 x + 0.65 y = 1.29 -----------(2),

0.89 x × Equation(1),

We get,

0.89 x + 0.89 y = 1.602 ------------(3)

Equation(2)-equation(3),

We get, 0.24 y = 0.312 ⇒ y = 1.3

By Substituting this value in equation (1),

x = 1.8 -1.3 ⇒ x = 0.5

Thus, he bought chocolate-covered pretzels, x = 0.5 pounds,

And, gumdrops, y = 1.3 pounds.
