Find the values of the variables in each figure.

Mathematics
1 answer:
Diano4ka-milaya [45]2 years ago
8 0

Answer:

x = 40

Step-by-step explanation:

2x = 4x - 40 (recall properties of a parallelogram)

Solve for x

2x - 4x = 4x - 40 - 4x (subtraction property of equality)

-2x = -40

-2x/-2 = -40/-2 (division property of equality)

x = 20

What does x and y equal if 3x-2 equal x-y equals 4
Alex17521 [72]
<h3>x is 2 and y is -2</h3>

<em><u>Solution:</u></em>

Given that,

3x-2 equal x-y equals 4

Which means,

3x - 2 = x - y = 4

Therefore,

x - y = 4

Also,

3x - 2 = 4

Simplify above expression

3x - 2 = 4

3x = 4 + 2

3x = 6

Divide both sides by 3

x = 2

Substitute x = 2 in x - y = 4

2 - y = 4

y = 2 - 4

y = -2

Thus x is 2 and y is -2

An epidemiologist is observing the decay pattern of a pathogenic bacteria after applying a vaccine. He starts with 2,000 bacteri
Viktor [21]

Answer:

Number of bacteria after 36 hour (A) = 381 (Approx)

Step-by-step explanation:

Given:

Number of bacteria (p) = 2,000

Total time (n) = 36 hours

Decay rate = 4.5 % = 0.045 per hour

Find:

Number of bacteria after 36 hour (A)

Computation:

A=p(1-r)^n

Number of bacteria after 36 hour (A) = 2,000[1-0.045]³⁶

Number of bacteria after 36 hour (A) = 2,000[0.955]³⁶

Number of bacteria after 36 hour (A) = 2,000[0.190599333]

Number of bacteria after 36 hour (A) = 381.19866

Number of bacteria after 36 hour (A) = 381 (Approx)
