NEED HELP! I don't know how to do these questions.. 1. Represent 3+2 using a tape diagram.

2. Represent x+2 using a tape diagram.

3. Draw a rectangular array for 3(3 + 2).

4. Draw an array for 3(x + 2).

Draw a tape diagram to represent each expression.
a. (x + y) + (x + y) + (x + y)

b. (x + x+ x) + (y + y + y)

c. 3x+ 3y

d. 3( x + y )

Find an equivalent expression by modeling with a rectangular array and applying the distributive property to the expression 5(8x + 3).

Exercise 2:
For parts (a) and (b), draw an array for each expression and apply the distributive property to expand each expression. Substitute the given numerical values to demonstrate equivalency.
a. 2(x + 1), x = 5

b. 10(2c + 5), c = 1

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
