Answer:

31/7

Step-by-step explanation:

8x+1 = 15x-30

31 = 7x

(31/7) = x

Answer:

8x + 1 =3x-6

--------

5

8x+1=15x-30

8x-15x= -30-1

-7x=-31

x=31

7

x=4.42

Ignore the negative sign, since that only affects the sign of the final product

3415₇ × 432₇

You can compute the product by considering the digit expansion, by which I mean first expanding each number as sums of powers of 7:

3415₇ = 3000₇ + 400₇ + 10₇ + 5₇

(It's the same thing as writing, for example, the decimal 3415 as 3000 + 400 + 10 + 5, just in a different base.)

Similarly,

432₇ = 400₇ + 30₇ + 2₇

Then apply the distributive property:

= (3000₇ + 400₇ + 10₇ + 5₇) × (400₇ + 30₇ + 2₇)

= 3000₇ × (400₇ + 30₇ + 2₇)

… + 400₇ × (400₇ + 30₇ + 2₇)

… + 10₇ × (400₇ + 30₇ + 2₇)

… + 5₇ × (400₇ + 30₇ + 2₇)

= {12}00000₇ + {9}0000₇ + 6000₇

… + {16}0000₇ + {12}000₇ + {8}00₇

… + 4000₇ + 300₇ + 20₇

… + {20}00₇ + {15}0₇ + {10}₇

where I use the curly braces to indicate products (written in base 10) of digits that exceed 6. Anything in these braces needs to be properly converted to base 7. For example,

{12}₇ = 7 + 5 = 15₇

So you would have

= 1500000₇ + 120000₇ + 6000₇

… + 220000₇ + 15000₇ + 1100₇

… + 4000₇ + 300₇ + 20₇

… + 2600₇ + 210₇ + 13₇

Add everything up:

• In the 7⁰ place,

3₇

• In the 7¹ place,

1₇ + 1₇ + 2₇ = 4₇

• In the 7² place,

2₇ + 6₇ + 3₇ + 1₇ = {12}₇ = 15₇

• Carry the 1 (underlined). In the 7³ place,

2₇ + 4₇ + 1₇ + 5₇ + 6₇ + 1₇ = {19}₇ = 25₇

• Carry the 2. In the 7⁴ place,

1₇ + 2₇ + 2₇ + 2₇ = {7}₇ = 10₇

• Carry the 1. In the 7⁵ place,

2₇ + 1₇ + 5₇ + 1₇ = {9}₇ = 12₇

• Carry the 1. In the 7⁶ place,

1₇ + 1₇ = 2₇

So, we end up with

3415₇ × 432₇ = 22045543₇

and thus

3415₇ × (-432₇) = -22045543₇

Hey there!

If you want to CONVERT a FRACTION INTO a DECIMAL , all you have to do is this SIMPLE step!

Which is to DIVIDE the NUMERATOR from the DENOMINATOR

The numerator is the TOP number

The denominator is the BOTTOM number

Now let’s solve for your answer

1/4 = 0.25 because 0.25 • 4 = 1

Answer: 0.25 ☑️

Good luck on your assignment and enjoy your day!

Answer:

The equation shows the temperature over time will be:

Hence, option (C) is correct.

Step-by-step explanation:

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

where m is the rate of change or slope and b is the y-intercept

Given that one very cold morning, it was -7°F.

Thus, the y-intercept = b = -7

Given that as the day went on, the temperature rose 3 degrees each hour.

Thus, the rate of change = slope = m = 3

Thus, substituting m = 3 and b = -7 in the equation

[tex]y = mx+b[/tex]

[tex]y = 3x + (-7)[/tex]

[tex]y = 3x - 7[/tex]

Therefore, the equation shows the temperature over time will be:

Hence, option (C) is correct.

Shawn

Step-by-step explanation:

Shawn sells 36/4 = 9

Brett sells 56/7=8

Therefore , Shawn sells more vehicles per week

Answer: Shawn

Step-by-step explanation:

36 ÷ 4 = 9

56 ÷ 7 = 8

9 is greater than 8 and bc if we divide the numbers it equals how many vehicles per week.

Answer:

23 ft

Step-by-step explanation:

The computation of the maximum length of the base of the triangle is as follows:

Area of triangle is = 4 × 6 ÷ 2

= 12 ft²

Now the maximum area of the rectangle is

= 150 - 12

= 138 ft²

L = ?

W = 6 ft

Area of rectangle is  = L × W

L × 6 = 138

L = 138 ÷ 6

= 23 ft

Answer:

To find the GCF, do the prime factorization of both numbers.

42 = 2 x 3 x 7

28 = 2 x 2 x 7

The GCF uses the numbers that appear in BOTH, 2 x 7 = 14 is the GCF of the numbers.  There is no variable GCF because there isn't a variable that appears in both.

Taking out the GCF gives you:

14(3x + 2y)

Step-by-step explanation:

Answer:

14(3x + 2y)

Find the GCF.

It is 14.

Use the distributive property.

Then, multiply each term.

If there's a point after 2: 13.2

If there's no a point after 2: 1320

Step-by-step explanation:

A= 6[tex]s^{2}[/tex]

Two numbers/variables touching like this means to multiply!

s=2.20

6x2.20= 13.2

Answer:

Store A

Step-by-step explanation:

Store A

50/100=0.5

0.5×5=2.5

The watch will be 50-2.5=47.5

Store B

60/100=0.6

0.6×20=12

The watch will be 60-12=48

So the watch price in store A is better

Answer:

You should buy from Store A because you're paying $0.50 less than if you were to buy from Store B.

Step-by-step explanation:

First, don't subtract if it's a percentage. You will want to multiply to get the amount you're removing from the original price.

Let's look at Store A. $50 and 5% discount. 50 * 0.05 = 2.5. Remove 2.5 from 50.

50 - 2.5 = 47.5

When you buy from Store A, you will pay $47.5

Let's look at Store B. $60 and 20% discount. 60 * 0.20 = 12. Remove 12 from 60.

60 - 12 = 48

When you buy from Store B, you will pay $48

Ultimately, Store A is the best option because you're paying less.

Answer:

The values are a=6, b=8

Step-by-step explanation:

System of Equations

We are given the system of equations:

ax - by = 4

bx - ay = 10

And it's known the solutions are: x=2, y=1.

Plugging in the solutions:

2a - b = 4      [1]

2b - a = 10      [2]

Now we have to solve the system above. Multiply [1] by 2:

4a - 2b = 8

Now we add with [2]:

3a = 18

a = 18/3 = 6

a = 6

From [2]:

2b - 6 = 10

2b = 16

b = 16/2 = 8

b = 8

The values are a=6, b=8
