What is 1 1/4 + (3 2/3 +5 3/4)?

Mathematics
1 answer:
n200080 [17]3 years ago
6 0

Answer:

Step-by-step explanation:

Because this whole problem focuses on the addition of mixed numbers, we can drop the parentheses right now without affecting the problem solution.

The two denominators shown are 4 and 3; the LCD is therefore 12.

Rewriting the problem, we get:

1 3/12 + 3 8/12 + 5 9/12, or

                  3 + 8 + 9

1 + 3 + 5 + ----------------

                         12

This simplifies to 9 20/12, or 10 8/12, or 10 2/3 (answer)

Find the area of the prism help ASAP!!
stiks02 [169]
To find the surface area of a prism, we must find the area of each side and add them up.

Let's first find the area of the triangular base.

The area of a triangle is \dfrac{1}{2} bh
Where b is the base length and h is the height.

The base length of the triangle is 10.5. The height is 10.

A_B= \dfrac{1}{2}bh= \dfrac{1}{2} \times 10 \times 10.5=52.5

The triangular base has an area of 52.5 cm².

The triangular top must also have the same area. Thus, it also has an area of 52.5 cm².

Now we to find the length of the 3 rectangles on the side of the prism.

The formula for the area of a rectangle is A=wl
where w is the width and l is the length.

All rectangles have a width of 8. They all have different lengths. If we find the area of all the rectangles, we have the following:

A_1=8 \times 10.5 = 84

A_2=8 \times 10 = 80

A_3=8 \times 14.5=116

Now, add up ALL the areas we found. We'll have our surface area once we do this.

52.5+52.5+84+80+116=385

The surface area is 385 cm². Hope this helps! :)

Solve 5x − 6y = −38 <br> 3x + 4y = 0
Leto [7]

Answer:

x = -76 , y = 57

Step-by-step explanation:

5x - 6y = -38

3x + 4y = 0

------------------

use 4 to multiply equation 1

5x(4) - 6y(4) = - 38(4)

20x -24y = -152

----------------------

use 6 to multiply equation 2

3x(6) + 4y(6) = 0(6)

18x + 24y = 0

------------------------

20x - 24y = -152

18x + 24y = 0

----------------------

2x = -152

----------------

divide 2 by both sides

x = -76

--------------------

to find y, slot in the of x to either equation 1 or 2

--------------------------------

equation 2

3x + 4y = 0

3(-76) + 4y = 0

------------------------

-228 + 4y = 0

4y = 228 - 0

4y = 228

---------------------

divide both sides by 4

----------------------------------

y = 57

for this type of question, you can use

  1. substitution method
  2. elimination method
  3. graphical method

i used substitution method

hope it helps
