i can barely see the majority of the questions
i cant do all but to multiply fractions, you just multiply the numerator and the denominator together
so 3 2/3 x 6
change 3 2/3 to an improper fraction
9/3 x 6/1 = 27/3 which is 9/1 reduced
10 x 1 2/3 is 10/1 x 5/3 = 50/3

Answer:

Step-by-step explanation:

1 - a) I can't see it clearly but if it's: 2/3 × 2/4 it will be 2/3 × 1/2 = 3/6 = 1/2

1 - b) 1/2 × 3/8 = 3/16

1 - c) 7/8 × 3/5 = 21/40

1 - d) 2/7 × 5/8 = 10/56

2 - a) 2/3 × 5 = 10/3

2 - b) 4 × 7/8 = 28/8 = 7/2

2 - c) 3/5 × 12 = 36/5

2 - d) 8 × 4/7 = 32/7

3 - a) 3×1/8 × 4 = 3/8 × 4 = 12/8 = 3/2

3 - b) 5 × 7×1/2 = 5 × 7/2 = 35/2

3 - c) 3×2/3 × 6 = 6/3 × 6 = 2 × 6 = 12

3 - d) 10 × 1×2/3 = 10 × 2/3 = 20/3

4 - a) 2×1/2 × 3×1/3 = 2/2 × 3/3 = 1 × 1 = 1

4 - b) 1×1/5 × 3×3/4 = 1/5 × 9/4 = 9/20

4 - c) 2×1/2 × 2×1/2 = 2/2 × 2/2 = 1 × 1 = 1

4 - d) 4×1/3 × 2×3/5 = 4/3 × 6/5 = 24/15 = 8/5

What is the value of x in the figure?

Enter your answer in the box.
x =

Answers

We need to do 90-61, which is 29. X = 29, because the base of 61 and the right of the x is equal to a right angle.

Answer:

x=29 degrees

Step-by-step explanation:

Both angles shown ad up to a 90 degree angle. We can see this because on the adjacent side there is a box indicating that it is a right angle. The three angles add up to 180, thus if we subtract 90 degrees due to the angle on the left of the y axis, the angles on the right of the y axis must add up to 90 as well.

Since the angles on the right must add up to 90, we set an equation to solve for x:

61+x=90(subtract 61)

x=29 degrees

) Ms. Pimentel went on a trip with the Glee Club. The trip was $365. Included in that price are $105 for a plane ticket, the cost of 2 luggage bags, and the hotel room for one night. The hotel room cost two times the amount of the plane ticket. What is the cost of one luggage bag? *

A. $25
B. $50
C. $130
D. $260

Answers

A. $25
The explanation would be because 365-105=206 and then double 105 which would be 210 and then subtract that from 206 which would be 50 then divide that by 2 and you would get 25

Let’s put that into an equation

Luggage bags will be represented in x
Since there’s 2 bags it will be 2x

The plane ticket cost $105. The hotel room cost TWO TIMES the amount of the plane ticket. So the hotel room would be 2(105)

Putting them together your equation would be:

365 = 105 + 2x + 2(105)

Now we solve from here:

2(105) = 210

210 + 105 = 315

Now we have:

365 = 315 + 2x

Isolate the variable so you have to Subtract 315 on both sides then you’ll have:

50 = 2x

Divide 2 on both sides:

25 = x

The cost of one luggage bag is $25.

What is the area of this polygon?
A) 24 cm2
B) 16 cm2
C) 40 cm2
D) 18 cm2

Answers

Answer:

C) 40 cm²

Step-by-step explanation:

area of top triangle = 1/2 x 8 x 6 = 24 cm²

area of bottom triangle = 1/2 x 8 x 4 = 16 cm²

24 cm² + 16 cm² = 40 cm²

C would be the answer this is the correct answer because it makes most sense and also that’s correct because

The area of the top is :1/2x8x6=24 cm
Next!!

The area of the bottom is:1/2x8x4=16cm
Next!!
24 cm +16 cm = 40cm
Next!!
