a) -2 = y + 5
c) –2x + 3x – 5 = 6 – 21
e) 4 – 14 = 5x
g) –42 + 20 = –2x + 13x
i) 7 = y – 2
k) –4 – 10 = 4y + 3y
m) 3y = –18
Answer:
a: y = - 7
c: x = -10
e: x = 2
g: x = -2
i: y = 9
k: y = -2
m: y = -6
Step-by-step explanation:
a: Subtract 5 on both sides
c: Add 5 on both sides then combine like terms
e: Combine like terms then divide by 5
g: Combine like terms then divide by 11
i: Add 2 on both sides
k: Combine like terms then divide by 7
m: Divide by three(won't add the number for some reason)

P.S.: I attached the table below:)
Answer the question below:
Answer:
C
Step-by-step explanation:
I would first try to get that fraction into x/100 because 100 is the easiest to work with.
In order to get from 40 to 100, you multiply by 2.5
So we should multiply 29 by 2.5 also to make it evened out.
29 x 2.5 = 72.5
72.5/100
Now we will move the decimal two places to the left on both sides because 100. is the same as 100
72.5/100. turns into .725/1
The closest thing to .725 is .7
Answer:
B 0.6
Step-by-step explanation:
29/40=0.725
0.725 rounded down is 6
Drag the tiles to the boxes to form correct pairs.
Using the given conversion table, match the distances in yards, inches, or miles to their equivalent distances in feet.
Ratio Conversion Table
mile : yard 1 : 1,760
yard : feet 1 : 3
feet : inch 1 : 12
3 miles
240 inches
900 feet
20 feet
1,790 yards
15,840 feet
66 feet
22 yards
300 yards
5,370 feet
Answer:
20 feet- 240in
900 feet- 300 yards
15840 feet - 3 miles
66 feet- 22 yards
5370 feet- 1790 yards
Step-by-step explanation:
1. 240 / 12 = 20ft
2. 300*3 =900ft
3. 15840ft / 3 = 5280yards / 1760 =3 miles
4.22*3= 66ft
5. 1790*3= 5370 ft
Deanna borrowed $650 at 8% 0 simple interest. How much - 52 interest did she pay for 1 year?
Answer:
i = ($650)(0.08)(1) = $52
Step-by-step explanation:
The formula for simple interest is i = prt. Here p = $650, r = 0.08 and t = 1 (year). Then the simple interest Deanna paid for this one year loan was
i = ($650)(0.08)(1) = $52
53 + 47 = 100 : simples?
53 + 47 = 100
53 + 47 = 100
53 + 47 = 100
53 + 47 = 100
53 + 47 = 100
53 + 47 = 100
Vito has an 8-inch by 10-inch piece of cardstock. He cuts it in the shape shown below and folds it on the dotted lines. He tapes the slides to make the box shown below. What is the surface area of the box?
Answer:
52 square inches
Step-by-step explanation:
you measure each side and do 2 times 3 twice and add them together, then you do 2 times 4 twice and add them together, then you do 4 times 3 twice and add all the numbers together and then you get 52

Answer:
1) 4 cm= 28 miles
2) 35 cm= 245 miles
If 1cm is equal to 7 miles then multiply 4 by 7 to get 28. And for the second problem you multiply 7 by 35 to get 245.

What information do we need to calculate the volume of a prism? Explain how you could use layers to find the volume of a prism.
Two prisms have the same base area and height, but different base shapes. Which prism has a greater volume? Explain.
Two clay prisms use the same amount of clay to make them, but the first has a larger height than the second. Which prism has a larger base area?
Answer:
1. To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.

how can you tell if an ordered pair (x,y) is a solution or a system of linear equations?
Answer:
you will know because it you do the system of whatever thingy and there are no two dots in the same row and the line is straight in either a negative or positive slope at a diagonal the equation is linear and its a function.
Step-by-step explanation:
The image is an example of a linear equation that is both a function and positive lenear
Answer:
To figure out if an ordered pair is a solution to an equation, you could perform a test. Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.
