Answer:
x = 1
Step-by-step explanation:
-3 + 4x + 3(4x + 8) = 4(7x + 3) - 3
first, solve the brackets by using the distributive property of multiplication:
3(4x + 8) = 12x + 24
4(7x + 3) = 28x + 12
rewrite equation:
-3 + 4x + 12x + 24 = 28x + 12 - 3
combine like terms:
16x + 21 = 28x + 9
subytact 21 on both sides:
16x + 21 - 21 = 28x + 9 - 21
16x = 28x - 12
subtract 28x on both sides:
16x - 28x = 28x - 28x - 12
-12x = -12
divide both sides by 12
[tex]\frac{-12x}{12} = \frac{12}{12}[/tex]
x = 1
to check, substitute 1 for x:
-3 + 4(1) + 3(4(1) + 8) = 4(7(1) + 3) - 3
-3 + 4 + 12 + 24 = 28 + 12 - 3
37 = 37

Is the probability of red a simple event, complement of a
simple event, or neither?
A. complement of a simple event
B. nelther
C. simple event
Answer:
Complement of an Event: All outcomes that are NOT the event. So the Complement of an event is all the other outcomes (not the ones we want). And together the Event and its Complement make all possible outcomes.

the perimeter of a rectangle is at least 74 cm the length of a rectangle is two more than four times the width of a rectangle what are the minimum dimensions of the rectangle
Answer:
2W+2L=perimeter=74
Step-by-step explanation:
2W=74-2L
2(2W)+2(L/2)=76
substitute 74 - 2L for 2W in the last equation to solve for L. Put that value in the first equation to find W. Check by putting both values into the last equation.
Which best describes the probability of the rolling a 7 on a number cube that is numbered from 1 through 6
Answer:
[tex]\huge\boxed{\text{Impossible}}[/tex]
Step-by-step explanation:
To find the probability of something happening, we find all the outcomes that can happen, find all the outcomes in which our criteria is met, and set that up as a fraction, where it's criteria met/total possible outcomes.
When we roll a 6-sided die, we will have 6 possible outcomes that we can roll.
1, 2, 3, 4, 5, and 6.
We can not roll anything except these 6! Since a die only has 6 sides, numbered 1-6, we will only roll these numbers.
7 is not in this list! It is impossible to roll a 7 on a die that only has 6 sides. Since 7 isn't even possible, it would be impossible to get a 7 on a 6-sided die.
Hope this helped!

A river 3m deep and 40 m wide is flowing at the rate 2km /h . how much water will fall into the sea in a minute.
Answer:
Area of river = depth × width
=3×40
[tex] = 120 {m}^{2} [/tex]
amount of water that falls into the sea ⇒
Area of river × flow rate
[tex]120 {m}^{2} \times 2 \: \frac{km}{hr} [/tex]
[tex]120 \times \frac{2 \times 1000 {m}^{2} }{(60)min} [/tex]
[tex]4000 \: \frac{ {m}^{3} }{min} [/tex]
:. [tex] {4000m}^{3} [/tex] of water falls into the sea per min.
So, [tex] {4000m}^{3} [/tex]
= 4000 × 1000 litres
= 4000000 litres
So, in 1 minute, water will fall into the sea is 4000000 litres.

4. Write the ratio for cos M.
cos M = 24/25
cos M = 12/25
cos M = 24/7
cos M = 25/24
Answer:
24/25
Step-by-step explanation:
Hello There
[tex]cos = \frac{adjacent}{hypotenuse} [/tex]
The adjacent of M is 24 and the hypotenuse is 25 so
[tex]cosm = \frac{24}{25} [/tex]
Answer:
cos M= base/hypotenuse=KM/LM=24/25

please help quick add egbtfdghy
Answer:
The second option is correct.
Step-by-step explanation:
If x = 5, then this happens.
1(5) - 2 < 3
5 - 2 < 3
3 < 3
That is incorrect because 3 = 3.
The second option is correct, because:
4 - 2 < 3
2 < 3
This work so the second option is correct
