Answer:

option (b) is correct.

The value of x in the equation 1.5(x + 4) – 3 = 4.5(x – 2) is 4.

Step-by-step explanation:

Given equation 1.5(x + 4) – 3 = 4.5(x – 2)

We have to solve for x,

Consider the given equation 1.5(x + 4) – 3 = 4.5(x – 2)

Simplify both side by multiplying 1.5 with each term in bracket on left side, and multiplying  4.5 with each term in bracket on right side, we get,

1.5x + 6 – 3 = 4.5x – 9

Now, simplify both sides, we get,

1.5x + 3 = 4.5x – 9

Taking like terms one side, we get,

4.5x - 1.5x = 9 + 3

Simplify, we get,

3 x = 12

divide both side by 3 , we get,

x = 4

Thus, the value of x in the equation 1.5(x + 4) – 3 = 4.5(x – 2) is 4.

Thus, option (b) is correct.

The correct answer is 4

1.5 (4+4) -3 = 9

4.5 ( 4-2) =9

Find the measure of the numbered angle.
Mila [183]
The angle adjacent to angle 6 is the one we need to find first.  To do this, add the measures of the intercepted arcs and divide by 2.  60 + 50 = 110, and half of that is 55.  That means that both adjacent angles to the angle 6 are 55 (vertical angles are congruent).  The measure of all the angles added together is 360 and angle 6 is vertical to the other "sideways" angle, so they are congruent as well.  360 - 55 - 55 = 250.  Split that up between angle 6 and its vertical angle to get that each of those measure 125.  Angle 6 measures 125, choice b from above.

What are two numbers that add up to 43 and their difference is 11?
LiRa [457]

Answer:

27 and 16

Step-by-step explanation:

x + y = 43

x - y = 11

You can add up the two equations so the ys are cancelled out.

2x = 54

x = 27

Plug x in to find y.

27 - y = 11

y = 16

Two numbers are in the ratio 7:5 and their difference is 22.Find the numbers​
omeli [17]

Answer:

Let x and y be the two numbers. Then

yx=57  and x−y=20

Cross multiplying the proportion

5x=7y  or y=75x

So, x−y=20

x−75x=20⇒77x−5x=72x=20

⇒x=2140=70

y=75x=75×70=50

So smaller number is 50.

Check :yx=5070=57 and 70−50=20
