Hello!

$\large\boxed{t = -8}$

We can find the value of t using the slope formula:

$slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Plug in the given slope and coordinates into the appropriate places:

$5 = \frac{2-t}{3-1}$

Simplify:

$5 = \frac{2-t}{2}$

Multiply both sides by 2 to begin isolating for t. Simplify and solve for t:

$5 * 2 = 2 - t\\\\10 = 2 - t\\\\8 = -t\\\\t = 8$

Answer:

$b-17$

Step-by-step explanation:

So, Tanvi started with b buttons.

And she gave away 17.

Since she "gave away," this means that we should use subtraction.

Therefore, she now has b-17 buttons.

Our expression is:

$b-17$

Solve 7b 3 - 4b = 3 - 3 (b 4)

frez [133]

7b + 3 - 4b = 3 - 3(b + 4)
3b + 3 = 3 - 3b - 12
3b + 3b = 3 - 12 - 3 = -12
6b = -12
b = -12/6 = -2
b = -2

angel's dad bought a television for her completing all of her digital learning day lesson. he want to warp the gift. the box mea

Answer: 13 sheets of paper

Step-by-step explanation:

We are given the dimensions of the box and the wrap paper:

Box:

$(56 in)(8 in)(36 in)$

Warp paper:

$(26 in)(17 in)$

Now we need to find the surface area of the box and the area of the wrap paper:

Box:

$surface_{1}=(56 in)(8 in)(2)=896 in^{2}$

$surface_{2}=(8 in)(36 in)(2)=576 in^{2}$

$surface_{3}=(56 in)(36 in)(2)=4032 in^{2}$

$surface-area=896 in^{2}+576 in^{2}+4032 in^{2}=5504 in^{2}$

Warp paper:

$area=(26 in)(17 in)=442 in^{2}$

Dividing the area of the box by the area of the paper:

$\frac{surface-area}{area}=\frac{5504 in^{2}}{442 in^{2}}=12.45 \approx 13$

This means Angel's dad needs to purchase 13 sheets of wrapping paper.
