Draw algebra tile models to prove that 4+8x and 4(2x+1) are equivalent

Answers

Modelling Algebraic expressions can be done through Algebra Tiles, this is done through squares and rectangles both representing variables and numbers. 4+8x and 4(2x+1) is equivalent because of its distributive property, in the second equation 4 is distributed or multiplied to 2x+1 making it 8x+4. To represent this with Algebra tiles, you need to divide the paper into two, draw a vertical line in the middle that represents equal sign and on the first column, you need to draw 4 squares and beside it are 8 thin rectangles and on the second column you need to draw 8 thin rectangles and beside it are 4 squares. If you can picture it out, basically both equations are equivalent.

Elena and Jada are 25 miles apart when they start moving toward each other. Elena runs at a constant speed of 6 mph and Jada walks at a constant speed of 4 mph. How long does it take for Jada and Elena to meet?

Answers

Answer:

The Time taken by Elena and Jade to meet up is 2.5 hours

Explanation:

Given,

Elena moves with a speed of 6mph while Jada walks at a speed of 4 mph

Also, Distance can be calculated by the formula

$Distance = Speed * Time$

To find out the Total speed, i.e., speed of both Elena and Jada as both of them are walking in opposite direction we should add the speed of both the persons, if in same direction we should subtract the values

Here it will be: $6 + 4$ = 10mph

Distance apart is given as 25 miles. Substituting the values,

$Distance = Speed * Time$

25 = $10 * time$

Time = 25/10

Time = 2.5 hour

Hence, It will take 2.5 hours to meet up.

Sequence. 4, 13, 28, 49, ?

Answers

Sequence: 4, 13, 28, 49
Now, differences between numbers = 13-4, 28-13, 49-18
= 9, 15, 21
We can see, difference is increasing by 6 at each step, so it would be 27 for next.

Next number = 49 + 27 = 76

In short, Your Answer would be 76

Hope this helps!

you have to list the differnences, then the 2nd differences

4, 13, 28, 49, ?
9 15 21
6 6 6
answer: 76

So tommy has 1/3 dimes as nickels so you need to guess and cheak a d then you go to the method they gave you and you get 2 dimes 6 nickels and 9 quarters

Nickels = 6
Dimes = 2
Quarters = 9

(1/3N) + N + (3+N) = 17
2 1/3N = 14
N = 6
