Answer:

6 pairs.

Step-by-step explanation:

Rebecca bought x pairs of socks and received a 20% discount.

Each pair of socks costs = $4.99

So cost of x pairs = (4.99x)

cost after 20% discount on x pairs of socks = x(4.99 - 20% of 4.99)

= x(4.99 - 0.998)

= 3.992x

Total cost of socks = $23.95

3.992x = 23.95

x = $\frac{23.95}{3.992}$

= 6 pairs.

Rabecca bought 6 pairs of socks.

(PLSSSS HELP) Determine which three out of the six points shown below are a solution to the equation x-3y=22 Plot the three poin

algol [13]

Answer:

$(-2,8)$ $(7,5)$ $(1,7)$

Step-by-step explanation:

Given

$x + 3y = 22$

Solving (a): The possible coordinates

We have:

$(x,y) = (-2,8)$

This gives:

$x + 3y = 22 \to -2 + 3 * 8$

$x + 3y = 22 \to -2 + 24$

$x + 3y = 22 \to 22$

<em>(-2,8) is a point on the grid</em>

$(x,y) = (7,5)$

This gives:

$x + 3y = 22 \to 7 + 3 * 5$

$x + 3y = 22 \to 7 + 15$

$x + 3y = 22 \to 22$

<em>(7,5) is a point on the grid</em>

$(x,y) = (-5,5)$

This gives:

$x + 3y = 22 \to -5 + 3 * 5$

$x + 3y = 22 \to -5 + 15$

$x + 3y = 22 \to 10$

<em>(-5,5) is a not point on the grid</em>

<em></em>

$(x,y) = (1,3)$

This gives:

$x + 3y = 22 \to 1 + 3 * 3$

$x + 3y = 22 \to 1 + 9$

$x + 3y = 22 \to 10$

<em>(1,3) is a not point on the grid</em>

$(x,y) = (1,7)$

This gives:

$x + 3y = 22 \to 1 + 3 * 7$

$x + 3y = 22 \to 1 + 21$

$x + 3y = 22 \to 22$

(1,7) is a point on the grid

So, we plot the following on the grid

$(-2,8)$ $(7,5)$ $(1,7)$

Can I get help with this ???

Semmy [17]

Okay so the small triangle has sides that are 3 units, 4 units and 5 units long
the larger triangle has sides that are 6 units, 8 units and 10 units long so using this information we can see that the larger triangle is twice the size of the small triangle.
Hope this helps :)
