Dima020 [189]

18x + 20 + x = 10x -3

Combine like terms

19x + 20 = 10x -3

Subtract 20 to both sides because whatever you do on one side you have to do it on the other side:

19x = 10x -23

Subtract 10x

9x = -23

Divide 9 to isolate x:

x = -23/9

Simplify to get a mixed number:

x = -2 5/9

An investor puts $2,500 into a life insurance policy that pays 8.5% simple annual interest. If no additional investment is made
Dima020 [189]

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Principal amount (P)= $2500

Rate of simple annual interest (R) = 8.5%

Number of years (T)= 10

As we know the formula for "Simple Interest ":

Interest=\frac{P\times R\times T}{100}\\\\Interest=\frac{2500\times 8.5\times 10}{100}\\\\Interest=\$2125.00

Hence, Option 'B' is correct.

PLZ HELP Find the value of x that makes ΔXYZ~PQR
Galina-37 [17]

Answer:

x = 8

Step-by-step explanation:

\triangle XYZ \sim\triangle PQR... (GIVEN) \\\therefore \frac{XY}{PQ} = \frac{YZ}{QR}.. (csst) \\\therefore \frac{20}{30}= \frac{x+6}{21}\\\therefore \frac{2}{3}= \frac{x+6}{21}\\\therefore \frac{2\times 21}{3}= {x+6}\\\therefore 14= {x+6}\\\therefore 14-6= {x}\\\therefore 8= {x}\\\huge \orange{\boxed {\therefore x = 8}}
