I WILL GIVE BRAINLIEST IF YOU SOLVE THEM ALL!!
Find the numerical values of the following expressions:
a) | 3 | a | +5 | b | if a=−2; b=−1
b) |2x−3y| if x=0.5; y=−0.7
c)| 4 | a | +8−a | if a=−2
d) |−3 | x | +2x−1 | if x=−5

Step-by-step explanation:

1. |-2*3|= |-6| 6 -1*5= -5 |-5| = 5 6+5 = 11 For the first one the answer is 11

2. 0.5*2= 1 -0.7*3 = -2.1.              1-(-2.1)=3.1 |3.1|= 3.1 the 2nd problem answer is 3.1

3.  a= -2 absolute value of -2 = 2  2*4=8 8+8-a= 8+8-(-2) = 18

4.  x=-5 |x| = 5 -3*5= -15 2x= -10    -15+-10-1 = -26

pls give brainliest this will be my first brainliest if you give it to me it is all correct

i think that you should ask google for the answer to that problem because if we don't know it google does

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
