True or false, if y=7, then 5+27 < 20 (5,3) is a solution for 4x-3y = 11
-|21| is always positive
A line that is going up and to the right has a negative slop
The area of a circle with a radius of 7 is 153.9
There are two solutions to the equation |x-21|= -7
45 divided by 5 times 3 = 27
(These are all just true or false questions.)

step-by-step explanation:

8+13=21

21+8=29

29+6=35

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
