translate into an algebraic expression: 120 is decreased by d% and increased by 25%. what is the result
2 answers:
Answer:
150(1-x)
Step-by-step explanation:
120 is decreased by d%
Let x = d%
120 - 120*x
120(1-x)
Then it is increased by 25%
(120 (1-x)) +(120 (1-x))*.25
(120 (1-x)) +(30 (1-x))
150(1-x)
Answer:
Solution given:
120 is decreased by d%
in algebraic expression
<u>120-d% of 120</u>
and then
increased by 25%
in algebraic expression
(120-d% of 120)+25% of (120-d% of 120)
(120(1-d%))+120/4*(1-d%)
(1-d%)(120+30)
<u>150(1-d%)</u> is a required algebraic expression.

Step-by-step explanation:
6/100× $85.25
x=$511.50 divided by 100
x=$5.1150 Or $5.12
rounded to the nearest cent
-6 x -6 x -6 = -216
-6 + -6 + -6 = -18
So the answer is negative 6
Step-by-step explanation:
Primero tienes que encontrar el número que te encuentres con 5 y con el mismo número lo haces con 7.
Y = 6
x = 7
It’s the answer
