A investor has an account with stock from two different companies. Last year her stocking company A was worth $4600 in her stock
aalyn [17]

Answer: 24.5%

Step-by-step explanation:

Last year her stock in company A was worth $4600. If her Stock in company A has decreased by 25% since last year in stock, then the amount by which it decreased is

25/100 × 4600 = $1150

The present worth is

4600 - 1150 = $3450

Also, her stock in company B was worth $1000. If her Stock in company B has decreased by 22% since last year in stock, then the amount by which it decreased is

22/100 × 1000 = $220

The present worth is

1000 - 220 = $780

The total worth of both stocks last year was

4600 + 1000 = $5600

The total worth of both stocks this year was

3450 + 780 = $4230

The amount by which it decreased is

5600 - 4230 = 1370

the total percentage decrease in the investor stock account is

1370/5600 × 100 = 24.5%

Seven more than three times a number is thirty-one. Write an equation
olga_2 [115]

Answer:

As an equation, (we'll use x as the variable), that word problem is 3x+7=31.

To solve we'd subtract 7 from both sides to isolate 3x, which gives us 3x=24. Now, to isolate x(unknown number) we would divide both sides by 3. When you divide both sides by 3, you'd get x=8.

Solve for R using cross multiplication
topjm [15]

R/ r+ 15 = 3/8

Cross multiply: top of one side multiplied by bottom of other side:

R x 8 = 3 x r+ 15

Simplify:

8r = 3r + 45

Subtract 3r from both sides:

5r = 45

Divide both sides by 5:

R = 9
