The total is 94 units.
A square has four equal sides so...
(5x-1)+(4x+3)+(5x-1)+(4x+3)=94
Combine like terms
19x+4=94
Subtract 4 from both sides
94-4=90
18x=90
Divide by 18 on both sides
90/18=5
X=5
Plug 5 in for x on the length of PQ
4(5)+3
20+3=23
Length of PQ=23 units
The tax is 3.60, the total is 51.60

Answer:
3/4 is equivalent to 9/12,
Step-by-step explanation:
So we know that 3/4 is equivalent to 9/12, because 3×12=36 and 4×9=36. A simple way to look at how to check for equivalent fractions is to do what is called “cross-multiply”, which means multiple the numerator of one fraction by the denominator of the other fraction.
Step-by-step explanation:
5 3/5 + 2 4/10 rewrite the sum
(5+2)+(3/5+4/10) calculate
7+1 calculate
8 solution
