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

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
