Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

A triangle has three sides and a pentagon has five sides.

The above statement is considered as Conjunction.

As we know that when two simple sentences or statements are joined by a word then this word is known for conjunction.

After removing the conjunction, we get two different simple and complete statements.

Like if we remove 'and'.

The two statements would be

1) A triangle has three sides.

2) A pentagon has five sides.

Hence, Option 'A' is correct.

A factory manufactures a metal piece in 32 minutes. New technology allowed the

Scorpion4ik [409]

It takes 28 minutes to manufacture the piece now.

<u>Step-by-step explanation:</u>

It is given that,

A factory manufactures a metal piece in 32 minutes.

After the new technology,

the factory cut that time by 8%.

Therefore, the time after the new technology is known by reducing the 8% of total time from the 32 minutes.

⇒ 8% of 32 = (8/100) × 32

⇒ 0.08 × 32

⇒ 2.56 minutes

The time after the new technology allowed = 32 minutes - 2.56 minutes

⇒ 29.44 minutes.

Again,

the time is cut by 5% after the another improvement.

Therefore, the time after the another improvement is known by reducing the 5% of previous time 29.44 minutes.

⇒ 5% of 29.44 = (5/100) × 29.44

⇒ 0.05 × 29.44

⇒ 1.472 minutes

The time after the another improvement = 29.44 minutes - 1.472 minute

⇒ 27.9 minutes. (Which is approximately 28 minutes)

Which represents the solution(s) of the system of equations, y + 4 = x2 and y-x=2? Determine the solution set by

Sergeu [11.5K]

Answer:

The points (-2, 0) and (3,5) are the ONLY solutions of the given sets of equations.

Step-by-step explanation:

Here, the given equations are: $y + 4 = x^{2} , y -x = 2$

Now checking for the given points:

(a) (-2, 0)

Here, $y + 4 = 0 + 4 = 4 = (-2)^{2} = x^{2} \\y- x = 0 -(-2) = 2 = RHS$

Hence, (-2, 0) is the solution of the given equations.

b) Checking for (2,0), as (-2, 0) is a solution as shown above

Here, $y + 4 = 0 + 4 = 4 = (2)^{2} = x^{2} \\y- x = 0 + (-2) = -2 \neq 2(RHS)$

Hence, (2, 0) is NOT the solution of the given equations.

c) Checking for (3,5), as (-2, 0) is a solution as shown above

Here, $y + 4 = 5 + 4 = 9 = (3)^{2} = x^{2} \\y- x = 5 -3 = 2 - (RHS)$

Hence, (3,5), is the solution of the given equations.

Hence, the points (-2, 0) and (3,5) are the ONLY solutions of the given sets of equations.

8. The sum of two numbers is 8 less than twice the first number. Their difference is 4 less than twice

Delicious77 [7]

Answer:

14 and 6

Step-by-step explanation:

Let's start by naming the first number x.

We can name the second number y.

We can set up equations to model our situation.

x+y=2x-8

x-y=2y-4

Let's simplify the equations.

x+y=2x-8

Subtract 2x from both sides

-x+y=-8

__________

x-y=2y-4

Subtract 2y from both sides.

x-3y=-4

Add the two equations together to eliminate x.

x-3y=-4

-x+y=-8

________

0x-2y=-12

-2y=-12

Divide both sides by -2.

y=6

The second number is 6.

Plug that back in.

x+6=2x-8

Subtract x from both sides

6=x-8

Add 8 to both sides

x=14

The first number is 14
