How to find the value of X it's really confusing

Dovator [93]

I believe the answer to your problem is x=1.25
You will want to get rid of the fraction so you multiply both sides of the equation by 2 and so you'd get
4+2(8x+11)-12=34 then you distribute
4+16x+22-12=34 then combine like terms

16x+14=34 and then move over 14
16x=20and then divide and isolate x
x=1.25

which property is illustrated by the following statement? 8+3.4=3.4+8? Associative Property of Addition, Inverse property of add

kykrilka [37]

Consider the given statement:

8+3.4=3.4+8

We have to identify the property used in this statement.

1. Associative Property of Addition: Let a,b and c be three real numbers. This property states that $a+(b+c) = (a+b)+c$ . This property is not used in the given statement.

2. Inverse property of addition: A number 'a' is said to have an inverse '-a' if $a+(-a)=0$ . This property is not used in the given statement.

3. Inverse property of multiplication: A number 'a' is said to have an inverse ' $\frac{1}{a}$ ' if $a \times \frac{1}{a}=1$ . This property is not used in the given statement.

4. Commutative property of addition: Let 'a' and 'b' be two real numbers. This property states that $a+b = b+a$ .

In the given statement, 8+3.4=3.4+8

which is expressed as 8+12 = 12+8, this statement holds commutative property of addition as whether 8 is added to 12 or 12 is added to 8, the result is same.

So, Commutative property of addition is illustrated in this statement.

There are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag. What is the theoretical probability of randomly drawing

irinina [24]

The answer is 52% because there is a total of 25 marbles and if you add the red and blue marbles you get 14 which is more than the green mables which is more than half the amount of the total marbles

Find the volume of a pyramid with a square base, where the side length of the base is

ValentinkaMS [17]

Answer:

Step-by-step explanation:

Volume of a pyramid can be found by using the formula

$v = \frac{1}{3} \times a \times h \\$

a is the area of the base

h is the height

Since the base is a square we have

$v = \frac{1}{3} \times {15.3}^{2} \times 19.6 \\ = 78.03 \times 19.6 \\ = 1529.388$

We have the final answer as

Hope this helps you
