Regroup to express the number in a different way. \begin{aligned} 16{,}590=& 1 \text{ ten thousand} + 6 \text{ thousands} + 5 \text{ hundreds} + 9\text{ tens} 16{,}590=& 1 \text{ ten thousand} + 6 \text{ thousands} + 4 \text{ hundreds} + \bigstar\text{ tens} \end{aligned} 16,590= 16,590= 1 ten thousand+6 thousands+5 hundreds+9 tens 1 ten thousand+6 thousands+4 hundreds+★ tens

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

d) 48

step-by-step explanation:

16,32,48,64,80,96,112,128,144,160,176,192,208,224,240,256,272,288,304,320,336

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
