Find the whole using the percent proportion.

MAVERICK [17]

Answer:390

Step-by-step explanation:

130% of a=507

130/100 x a=507

13/10 x a=507

13a/10=507

Cross multiplying we get

13a=507x10

13a=5070

Divide both sides by 13

13a ➗ 13=5070 ➗ 13

a=390

P-6+2<-5 solve each inequality and graph its solution, i am lost

DerKrebs [107]

Answer:

P < -1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

$P - 6 + 2 < -5$
$P - 4 < -5$

Step 2: Add 4 to both sides.

$P - 4 + 4 < -5 + 4$
$P < -1$

Therefore, the answer is P < -1! (Also, the graphed solution is below.)
