Answer:

x>8.6

Step-by-step explanation:

We want to model an expression for the amount of money Caleb has and how many week he must work to have that amount

given data

amount at hand=$150

weekly saving=$75

let the number of weeks be x

total amount= $800

the expression for this situation is given as

y=mx+c

where y=800

m=75

c=150

substituting we have

800=75x+150

solving for x we have

800-150=75x

650=75x

x=650/75

x=8.6

then he must work for x>8.6 weeks

Answer:

9 rows

Step-by-step explanation:

Given that:

Li Na wants to plant 63 tomato plants and 81 rhubarb plants

However, Li Na was hoping with the mindset to plant the plants in rows;

where each row possesses the same number of tomato plants and rhubarb plants.

So;

Suppose we choose a given number, Let's say (9) to be the divisor for both the number of tomato plants and rhubarb plants;

Then

63/9 tomato plants = 7 tomato plants

81/9 rhubarb plants = 9 rhubarb plants

Therefore, the greatest number of rows Li Na can plant 7 tomato plants and 9 rhubarb  plants = 9

Answer:

x=0

y=2

z=-3

Step-by-step explanation:

x-y-2z=4    ...(1)

3x+y-z=5   ...(2)

adding

4x-3z=9   ...(3)

z=-3   ...(4)

put in (3)

4x-3(-3)=9

4x+9=9

4x=9-9=0

x=0

put in (1)

0-y-2(-3)=4

-y+6=4

y=6-4=2

x=0,y=2,z=-3

Answer:

1/3^7

Step-by-step explanation:

Negative exponents go to the denominator

The positive exponent for the given exponent is [tex]\frac{1}{3^7}[/tex].

The given exponent is [tex]3^{-7}[/tex].

The exponent of a number shows how many times the number is multiplied by itself.

A positive exponent tells us how many times to multiply a base number, and a negative exponent tells us how many times to divide a base number.

Now, [tex]3^{-7}=\frac{1}{3^7}[/tex] (∵[tex]a^{-n}=\frac{1}{a^n}[/tex])

Therefore, the positive exponent for the given exponent is [tex]\frac{1}{3^7}[/tex].

Step-by-step explanation:

After eight years, the value of Edward's home increased by $24,386.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

We have to given that;

Edward purchased his home for $89,000.

For the first three years after he moved in the real estate market was very lively, so his property value grew by 4.8% every year.

And,  For the next five years, the market slowed down somewhat, and his property value grew by 2.6% every year.

Now,

After three years, the value of Edward's home increased by,

⇒ 3 × (4.8% of $89,000)

⇒ 3 × (4.8/100 × 89,000)

⇒ 3 × 4,272

⇒ $12,816

And, After five years, the value of Edward's home increased by,

⇒ 5 × (2.6% of $89,000)

⇒ 5 × (2.6/100 × 89,000)

⇒ 5 × 2,314

⇒ $11,570

Thus, After eight years, the value of Edward's home increased by,

⇒ $12,816 + $11,570

⇒ $24,386

Answer:

3.28833605E+18 (Scientific Notation, for example, aE+b = a × 10^b) [ 3,288,336,052,853,678,818 ]

Step-by-step explanation:

123-20+8,098*67^8 =

(123 - 20) + (8,098 × 67^8)

103 + (8,098 × 67^8)

103 + 3,288,336,052,853,678,715 [3.28833605285367815E+18] =

3,288,336,052,853,678,818 [3.28833605285367815E+18]

≈ 3.28833605E+18

This is due to the order of operations, that defines the mathematical steps to solve arithmetic problems. This is known as PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction).

So each part of the expression must be worked out in a certain order to get the correct answer.
