Answer:

No

(The first system is correct but the second one is wrong)

Step-by-step explanation:

You can plug (-10,10) into these equations

a)  18(-10)+20(10)=20

      -180+200=20

            20=20

b) 20(-10)-2(10)=9

      -200-20≠9

         -220≠9

Answer:

5

Step-by-step explanation:

1.24 times 3 = 3.72

.95 (the value of pence to a pound in decimal form) = 2.85

6.18 for the teapot

2.72+2.85+6.18=11.75

She now has £8.25 left (20-11.75).

8.25/1.57=the amount of plates she can buy: 5.25477707006, so 5 with some money left

Answer:

10

Step-by-step explanation:

Plug in the values to "x" and "y" and solve.

Solve:

2(2) - 3(2(2) - 1(2) - 4)

2(2) - 3(4 - 1(2) - 4)

2(2) - 3(4 - 2 - 4)

2(2) - 3(-2)

4 - 3(-2)

4 + 6

Your answer would be 10.

Answer:

4/3 : 1

Step-by-step explanation:

Here, we want to express 8:6 in the form n:1

All we have to do is to divide both ratio sides by 6

That would be;

8/6 : 6/6

= 4/3:1

Answer:

All real numbers

Step-by-step explanation:

3(5x - 4) < 15x

~Distribute left side

15x - 12 < 15x

~Subtract 15x to both sides

-12 < 0

Answer:

down below

Step-by-step explanation:

set up two equations:

x + 4 = 6                    x + 4 = -6

solve both:

x = 2                          x = -10

plug it back in to the original equation:

|2 + 4| = 6.                 |-10 + 4| = -6

|6| = 6.                       |-6| = -6

6 = 6.                         since absolute value is always positive:

correct.                     |6| = -6

                                6 does not = -6

write both of these down if you need to show your work

Answer:

Steps: 1) Isolate the absolute value on the LEFT Side of the equation ... 12) A recent poll suggests that 47% of American citizens are going to vote for the ... margin of error of £4.5%. Set up and solve an absolute value inequality to determine the range of possible ... determine if the Democratic candidate will win the election?

Step-by-step explanation:

The percentages candidate could earn falls in the range of absolute value inequality |47 - x| ≤ 4.5.

Absolute value inequalities are kind of inequality expressions which includes the absolute value symbol in the expression.

For example : |x - 5| < 4 is an absolute value inequality.

Given that,

Percentage of American citizens going to vote for candidate B = 47%

Tolerance level = 4.5%

Suppose x be the percent of voters who will vote for candidate B.

Value of x can be,

47% + 4.5% = 51.5%

Or,

47% - 4.5% = 42.5%

The absolute value inequality for the situation is,

|47 - x| ≤ 4.5

Hence the absolute value inequality is |47 - x| ≤ 4.5.

Answer:

168*pi square yards.

Step-by-step explanation:

So, first the surface area of a cylinder is the sum of the two circles plus the rectangle forming the column.

The area of the column is the height x perimeter of the circle

and

The area of the circles is pi x radius^2

Just add all of those up.

Column: 5 * 2 * pi * 7 = height * 2pi * radius = 70*pi

2 x Circle = 2 x pi * 7^2 = 2x49*pi = 98*pi

Sum: 70*pi + 98*pi = 168* pi

Answer:

B: 8^3 in squared

Step-by-step explanation:

2^3 = 2*2*2= 8

4^3 =4*4*4=64

Area of rectangle equals length times width.

So, 8 * 64 equals 512 and 8^3= 512

Use calculator. Also, you can just treat it as normal multiplication and choose the one with the same units. so it would be 8, but then the next thing you would need to look at is the exponent. Since 8^6 is not the same exponent as the two in the problem, it has to be the 8^3, which are the same  

Answer:

m = -3/5

Step-by-step explanation:

Since the line is going downwards towards the right, it is a negative slope.

We can use the points to solve for the slope.

m = -2 - 1 / 2 - (-3)

m = -2 - 1 / 2 + 3

m = -3/5

Therefore, the slope is -3/5.

Step-by-step explanation:

Given that:

Cost of Ashley's dinner in Bloomington = $20

Sales tax = 10%

Tip = 15% on $20

To find:

Total cost of the meal ?

Solution:

Let us find the sales tax first of all.

Sales tax is 10% of the total bill.

Therefore, sales tax = 10% of $20

[tex]\Rightarrow \dfrac{10}{100}\times 20\\\Rightarrow \$2[/tex]

Tip left is 15% of the total bill.

Therefore, tip = 15% of $20

[tex]\Rightarrow \dfrac{15}{100}\times 20\\\Rightarrow \$3[/tex]

Now, total cost of the meal = Food cost + Sales tax + tip

Total cost of the meal = $20 + $2 + $3 = $25
