Question is in image.
a. x = 4, RS = TS = 23, RT = 7
b. x = 2, RS = TS = 20, RT = 5
c. x = 3, RS = TS = 29, RT = 8
d. x = 5, RS = TS = 18 RT = 4

Solve the following linear equations :

(i) x + 2 = 5x

→ 2 = 5x - x

→ 2 = 4x

→ x = 4/2

→ x = 2

(ii) 3(n - 1)/2 = n - 4

→ 3 × (n - 1)/2 = n - 4

→ 3n - 3/2 = n - 4

→ 3n - 3 = 2(n - 4)

→ 3n - 3 = 2 × (n - 4)

→ 3n - 3 = 2n - 8

→ 3n - 2n = -8 + 3

→ n = -5

Answer:

Answer:

B = x = 44 degrees

Step-by-step explanation:

Interior angles of a triangle = 180 degrees.

There are 2 congruent sides so the angle to the right of 67 degrees is also 67 degrees

180 - 2(67) = 46 degrees (the third angle of the triangle)

x + 46 degrees = 90 degrees ( complementary angles)

x = 44 degrees

Answer:

740 feet

Step-by-step explanation:

The speed of the cheetah is 74 feet per second:

speed = distance ÷ time

= 296 ÷ 4 = 74 feet per second

In 10 seconds:

distance = speed × time

= 74 × 10

= 740 feet

Answer:

740 Feet

Step-by-step explanation:

Given:  296 ft= 4 sec

To Find: 10 sec = [tex]\left[?}\right][/tex] ft

First we need to Find How many feet are in 1 second.

To find that,

Do 296 divided by 4

=

74

So 1 second = 74 Feet.

Then 74 ft Times 10 second

Which gives you

740 Feet.

Therefore, at 10 second rate gives you 740 Feet.

After the increase in the dimensions of the sign, the effect on the area of the sign is that the new area is 8 times larger than the initial area.

The sign has the shape of a rectangle. A rectangle has four sides. The opposite sides are equal in length.

The area of a rectangle = length x width.

Jimmy is making the sign bigger by increasing the size of the length and width. Let's imagine that the width is 8cm and the length is 10cm.

The initial area of the sign = 10 x 8 = 80 cm

After the increase in the dimensions, the length is are 40cm and 16cm for the width.

New area = 40 x 16 = 640

Number of times the new area is greater than the initial area = 640 / 80 = 8 times larger

Answer:

C =9

Step-by-step explanation:

10(c−1)=80

Step 1: Simplify both sides of the equation.

10(c−1)=80

(10)(c)+(10)(−1)=80(Distribute)

10c+−10=80

10c−10=80

Step 2: Add 10 to both sides.

10c−10+10=80+10

10c=90

Step 3: Divide both sides by 10.

10c

Based on the cost of filling of the car, we can infer that Mr. Johnson does not have enough to spend on gas.

The car can take 25 gallons of gas and already has 4 liters inside it. The quantity of gas Mr. Johnson has to buy is:

= 25 - 4

= 21 gallons

The price of a gallon is $3.04. The price of 21 gallons would be:

= Price of gas x Number of gallons

= 3.04 x 21

= $63.84

In conclusion, Mr. Johnson does not have enough to spend on gas because he has only $50 yet the gas will cost $63.84.

Answer:

The population of India would reach 3 billion in about 112 years (year 2128)

Step-by-step explanation:

1. subtract 1.327 billion by 1.053 billion  (1.327-1.053)

2. The answer you should get is 274,000,000 (two hundred seventy four million)

3. multiply 274,000,000 by 7 (amount of people required to reach about 3 billion)

4. add the product (ans to multiplication problem) to 1.327 billion. (you should get 3.245 billion (3245000000).

5. multiply 16 by 7 (16x7) to get the number of years to reach 3 billion (maybe 112)

6. Add the product to 2016

Answer: 1 foot = 5/3 or 1.6666 pounds

Step-by-step explanation: to get 4 1/2 feet to one foot, you divide by 4 1/2. in this equation, 4 1/2 ft= 7 1/2 pounds. if you divide one side by 4 1/2, you also have to do the same to the other side. therefore you do 7 1/2 divided by 4 1/2 which will give you 1.6666 or 5/3.

1 foot= 5/3 pounds

Answer:

True

Step-by-step explanation:

Linear equations are often used to model the relationship between the dependent variable that is affected by changes in the independent variable.  

For instance, the linear function: f(x) = 2x + 3, where f(x) is the output (dependent variable) depends on the value of the input, x (independent variable).  

Therefore, the correct answer is True.

Answer:

q + q + 4

Step-by-step explanation:

q + q +4

Answer:

true

Step-by-step explanation:

False, receive a pay raise of 5% then receive a pay cut of 5%. after the two changes in pay, your salary is changed.

Given that,
To justify the given statement is false or true.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

here,
let the salary be x,
Salary after 5% raise = 1.05x
Salary after cut of 5% = [1 - 0.05] [1.05x]
Salary after a cut of 5% = 0.9975x
So the salary becomes 99.75% of the original salary x.

Thus, the given statement is false, receive a pay raise of 5% then receive a pay cut of 5%. after the two changes in pay, your salary is changed.
