Mathematics
1 answer:
son4ous [18]3 years ago
8 0

Answer:

x = 5.5

Step-by-step explanation:

Based on the Mid-segment theorem of a triangle, we would have the following:

EF = 2(AB)

AB = 7

EF = 2x + 3

Plug in the values

2x + 3 = 2(7)

Solve for x

2x + 3 = 14

Subtract 3 from each side

2x + 3 - 3 = 14 - 3

2x = 11

2x/2 = 11/2

x = 5.5

Jim is investing in the stock market. Jim is hoping to earn $2,000 in interest in order to take a trip to Mexico. Stock A earns
Vanyuwa [196]

Given:

Total amount for investment = $32000

Rate of interest for Stock A = 4%

Rate of interest for Stock B = 7%

Jim is hoping to earn $2,000 in interest.

To find:

The amount of investments in Stock A and Stock B.

Step-by-step explanation:

Let amount of investments in Stock A = $x

Amount of investments in Stock B = $y

Total amount for investment = $32000

x+y=32000        ...(i)

Rate of interests in Stock A and Stock B are 4% and 7%. Total interests is $2000.

0.04x+0.07y=2000           ...(ii)

From (i) and (ii), we get

0.04x+0.07(32000-x)=2000

0.04x+2240-0.07x=2000

-0.03x=2000-2240

-0.03x=-240

Divide both sides by -0.03.

x=\dfrac{-240}{-0.03}

x=8000

Put x=8000 in (i).

8000+y=32000  

y=32000-8000  

y=24000  

Therefore, the amount of investments in Stock A and Stock B are $8000 and $24000 respectively.
