Dante’s bath towel is 1 yard long Dante’s bath towel is 1 yard long. What measure is equivalent to 1 yard, in inches? A 3 B 12 C 36 D 108

How many inches are in a yard? Dante’s bath towel is 1 yard long. What measure is equivalent to 1 yard, in inches? How many inches are in a yard?

Dante’s bath towel is 1 yard long Dante’s bath towel is 1 yard long. What measure is equivalent to 1 yard, in inches? How many inches are in a yard? Maybe we should start by figuring out how many feet are in 1 yard…

Dante’s bath towel is 1 yard long Dante’s bath towel is 1 yard long. What measure is equivalent to 1 yard, in inches? 3 feet = 1 yard

How many inches equal 1 foot? Dante’s bath towel is 1 yard long. What measure is equivalent to 1 yard, in inches? How many inches equal 1 foot?

Dante’s bath towel is 1 yard long Dante’s bath towel is 1 yard long. What measure is equivalent to 1 yard, in inches? 12 inches = 1 foot

So how many inches are in 1 yard? Dante’s bath towel is 1 yard long. What measure is equivalent to 1 yard, in inches? We know: 12 inches = 1 foot and 3 feet = 1 yard So how many inches are in 1 yard?

Dante’s bath towel is 1 yard long Dante’s bath towel is 1 yard long. What measure is equivalent to 1 yard, in inches? I could multiply 12 inches by 3 (the number of feet in a yard) to find the answer…

Dante’s bath towel is 1 yard long Dante’s bath towel is 1 yard long. What measure is equivalent to 1 yard, in inches? A 3 B 12 C 36 D 108

Dante’s bath towel is 1 yard long Dante’s bath towel is 1 yard long. What measure is equivalent to 1 yard, in inches? A 3 B 12 C 36 D 108

Penn draws a triangle with one 90° angle Penn draws a triangle with one 90° angle. What could be the measures of the other two angles in Penn’s triangle?

I need to draw a picture… Penn draws a triangle with one 90° angle. What could be the measures of the other two angles in Penn’s triangle? I need to draw a picture…

I need to draw a picture and label it with what I know… Penn draws a triangle with one 90° angle. What could be the measures of the other two angles in Penn’s triangle? I need to draw a picture and label it with what I know…

All of the angles of a triangle add up to 180°. Penn draws a triangle with one 90° angle. What could be the measures of the other two angles in Penn’s triangle? All of the angles of a triangle add up to 180°. 90°

Penn draws a triangle with one 90° angle Penn draws a triangle with one 90° angle. What could be the measures of the other two angles in Penn’s triangle? I can subtract 90° from 180° to see how many degrees are left for the other 2 angles to share. 90°

Penn draws a triangle with one 90° angle Penn draws a triangle with one 90° angle. What could be the measures of the other two angles in Penn’s triangle? 180 - 90 90°

There are 90° to share between the other 2 angles. Penn draws a triangle with one 90° angle. What could be the measures of the other two angles in Penn’s triangle? There are 90° to share between the other 2 angles. 180 - 90 90 90°

… So the 2 angles I choose should add up to 90°. Penn draws a triangle with one 90° angle. What could be the measures of the other two angles in Penn’s triangle? … So the 2 angles I choose should add up to 90°. 180 - 90 90 90°

… So the 2 angles I choose should add up to 90°. Penn draws a triangle with one 90° angle. What could be the measures of the other two angles in Penn’s triangle? … So the 2 angles I choose should add up to 90°.

Penn draws a triangle with one 90° angle Penn draws a triangle with one 90° angle. What could be the measures of the other two angles in Penn’s triangle? 30 + 60 = 90°

I need to divide the numerator (top of the fraction) by the denominator (bottom of the fraction).

27 / 4 = 6 R3 If I write that as a mixed number, the remainder is the numerator of the fraction and 4 is the denominator.

27 / 4 = 6 R3 If I write that as a mixed number, the remainder is the numerator of the fraction and 4 is the denominator.

A factor is one of 2 numbers that can be evenly divided into a number...

I will write out the list of factors for each number and see what is the greatest factor they have in common.

8: 1, 2, 4, 8 16: 1, 2, 4, 8, 16

8: 1, 2, 4, 8 16: 1, 2, 4, 8, 16

8: 1, 2, 4, 8 16: 1, 2, 4, 8, 16

In order to solve for n, I need to subtract 65 from both sides of the equation, so n is by itself behind the equals sign.

-65 - 65 n = 310 - 65

-65 - 65 n = 310 - 65 n = 245
