Step-by-step explanation:
In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations. For example, 3x² − 2xy + c is an algebraic expression. Since taking the square root is the same as raising to the power, is also an algebraic expression.
1-5q+ 2(2.5q+8)
1-5q+5q+16
0+15
15
(The q goes away because in addition a negative and a positive of the same # equal 0 since its 0 there is no letter)
Answer:

Answer:
Blues Paints = 2.45 pints
Step-by-step explanation:
Let's generate an expression that would relate all the variables given:
Total pints of paints used:
9.8 = white + blue
Pints of white paint used:
= 3/4 of 9.8
=0.75 * 9.8
=7.35
Number of pint of BLUE PAINTS used:
9.8 = White Paints + Blue Paints
9.8 = 7.35 + Blue Paints
Blue Paints = 9.8 - 7.35
Blues Paints = 2.45
Kate used 2.45 pints Blues Paints for her bedroom
