Subtract 4x from the right side and add it to the left.

Now it is 7x + 8 =6

Subtract 8 from the left side and add it to the right.

7x = 14

Divide both sides by 7
7x/7 = 14/7

X = 2

Left side:

x+x+x+1+1+1+1+1+1+1+1 = 3x + 8

Right side:

x+x+x+x++1+1+1+1+1+1

Left side = Right side to solve x

3x + 8 = 4x + 6

Subtract 4x from both sides

3x + 8 - 4x = 4x + 6 - 4x

Simplify

-x + 8 = 6

Subtract 8 from both sides

-x + 8 - 8 = 6 - 8

Simplify

-x = -2

Multiply both sides by (-1)

-x * (-1) = -2 * (-1)

Simplify

x = 2

Answer

C. x = 2

3 Sean has 8-inch pieces of toy train track and Ruth has 18-inch pieces of train track. How

Morgarella [4.7K]

Answer:

Step-by-step explanation:

The smallest number that is divisible by two given numbers is called the Least Common Multiple (LCM) of those numbers.

What's the smallest number that is a multiple of 8 and also a multiple of 18?

One way to find out is to start making lists of multiples:

Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, and so on,

Multiples of 18: 18, 36, 54, 72, 90, 108, and so on.

This method can be a bit tedious, but in this case, it's clear that 72 is the LCM of 8 and 18.

Another method is to use the <u>prime factorization</u> of the two numbers.

Write 8 and 18 as the product of prime numbers; each number has a unique prime factorization.

8 = 2 x 2 x 2 = 2^3

18 = 2 x 3 x 3 = 2^1 x 3^2

To form the LCM, build a product of primes using the <u>highest exponent</u> in either of the two numbers.

LCM = 2^3 x 3^2 = 8 x 9 = 72.

Selena buys 4 peaches that weigh 1 pound in all. Each peach weigh the same amount. Peaches are on sale for $2.24 per pound. Writ

DENIUS [597]

Answer:

The required equation is

4p = 2.24

And p = 0.56 [ where p is in $]

Step-by-step explanation:

Given that Selena buys 4 peaches that weight 1 pound in all.

Peaches are on sale for $2.24 per pound.

Since the total weight of peaches is 1 pound.

So the price of 4 peaches is $2.24.

Let p be the price of 1 peaches.

Then the price of 4 peaches is $(4×p)

= $4p

According to the problem,

4p = 2.24

$\Rightarrow p=\frac{2.24}{4}$

⇒p=0.56 [ where p is in $]

The required equation is

4p = 2.24

And p = 0.56 [ where p is in $]

2. A sphere has surface area 16π. Find the radius of the sphere.

KiRa [710]

Answer:

The answer to your question is: 2.29 units

Step-by-step explanation:

Data

Volume = 16π

radius = ?

Formula

V = $\frac{4}{3}π r^{3}$

Process

16 π = $\frac{4}{3}π r^{3}$

$\frac{16(3)}{4} = r^{3}$

r³ = 12

r = 2.29
