The solution to the inequalities will be,

( 5 ) y ≥ 2

( 6 ) x < 3

( 7 ) No solution.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

The given inequalities will be calculated as:-

-4 ≤ 4( 6y - 12 ) - 2y

-4 ≤ 24y - 48 - 2y

-4 ≤ 22 y - 48

22y ≥ 44

y ≥ 2

4x + 3 < 3x + 6

4x - 3x < 6 - 3

x < 3

-5r + 6 ≤ -5( r + 2 )

-5r + 6 ≤ -5r - 10

No solution

Therefore, the inequalities are solved above.

You have to multiply:

First write the compound fractions as impropper fractions.

To do so, divide the whole number by one to express it as a fraction and add both fractions:

Rewrite the multiplication using the corresponding impropper fractions:

And solve the multiplication, numerator * numerator and denominator*denominator:

Apply difference of two square

19 in

1 yd

2ft

32 in

First, we have to convert all the length into a unique unit:

For example, inches:

Since

1 ft = 12 inches

2 ft = 2 x12 = 22 inches

1yd = 36 inches

Now, we have to order from least to greatest:

19 in-22in -32in-36in

In the original units:

19 in , 2ft, 32in ,1yd

The total area under the normal distribution curve is 1. z-scores are indicated in the horizontal axis below this curve. This means that the sum of areas under the curve at the left and at the right of a certain z-score must be equal to 1.

Then if the area at the right of the z-score that we are looking for is 0.04 the area at its left must be equal to 1-0.04=0.96. The area at the left of z is important because z-score tables usually show the areas at the left of several z-scores. Then the only thing that we have to do is look for the z-score associated with 0.96 in one of these tables. In your case the table that you should use is the one named "Normal Table -∞ to z". That table should look like this one:

As you can see the value 0.96 is associated with the row 1.7 and the column .05 which means that the z-score that meets that the area under the curve at its right is 0.04 is z=1.7+0.05=1.75.

Then the answer is 1.75

Answer:

The correct answer is:

The ordered pair (2, 3) is not a solution to the system.

Explanation:

The system given is:

If (2, 3) is a solution of the system, then replacing x = 2 and y = 3 on both equations should give a correct result and the same on both equatiions.

In the first equation;

We can see that this result is not true, as 27 is not equal to 1.

In the second equation:

Once again, a false result.

To see in the system has equations, let's solve for x in the second equation:

Now, we can use substitution in the first equation:

And solve for y:

Now, we can find the value of x:

The solution to the system is (-2, 1)

Thus, the correct option is "The ordered pair (2, 3) is not a solution to the system"

1 pinch = 2 smidgens

1 dash = 2 pinches

Therefore, 1 dash = 2 x 2 smidgens

1 dash = 4 smidgens

1 teaspoon = 8 dashes

1 teaspoon = 8 x 4 smidgens

1 teaspoon = 32 smidgens

There are 32 smidgens in 1 teaspoon

Answer:

<A=32°

Explanation:

<BEC = 90° because it has the red half square and we know that <DCE = 42°. <ACB= 2x because <ACD and <DCB both =x. The equation we would set up is

90+(42+x) +2x=180

We get x=16.

Since <ACB = 2x we multiple 16 by 2

16*2=32

So <ACB =32°

SOLUTION:

Case: Rectangles

Method:

The sum is:

w + w + 2w + 5 = 89

4w + 5 = 89

4w = 89 - 5

4w = 84

w = 84/ 4

w= 21 feet

The length, l

l = 2w + 5

l = 2( 21) + 5

l = 42 + 5

l = 47 feet

Final answer:

length of the patio, l = 47 feet

width of the patio, w= 21 feet

The value of S in the expression 5/8-3/8 S = two minus S is 2 1/5.

An expression is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario.

In this case, this is illustrated thus:

5/8 - 3/8S = 2 -S

Collect like terms

-3/8S + S = 2 - 5/8

5/8S = 1 3/8

Divide

S= 1 3/8 ÷ 5/8

S = 11/8 × 8/5

S = 11/5

S = 2 1/5

This illustrates the concept of expression.

We are trying to get the equation for the horizontal line passing through the point (-6,-6).​

( x1 , y 1 ) = ( 0, 0 )

( x2 , y2 ) = ( -6 , -6 )

Gradient, m = ( y2 - y1 ) / ( x2 - x1 )

m = ( -6 -0 ) / ( -6 - 0 )

m = -6 / - 6

m = 1

Then, using the equation of a line;

y - y 1 = m ( x - x 1 )

y - 0 = 1 ( x - 0 )

y = x

• Chord: ,a line segment connecting ,any two points, in a curve (circle).

• Diameter: ,a chord passing ,through the center ,of the figure.

• Radius: ,a line segment going ,from the center, to any point in the circumference.

The difference between them is that the chord is any two points touching the circumference, the diameter has to go through the center to any two points, and the radius goes from the center to just one point in the circumference.

Then, the line segment that meets the requirements of being the diameter in circle F is segment CD as it passes through the center.

The radius could be CF, DF, and EF. While a chord could be AB.

Answer: CD

sphere: 12 pounds

cylinder: 108 pounds

Explanation:

Data:

. From balance A:

3 cubes + 1 sphere = 1 cylinder + 2 spheres

. From balance B:

3 cubes = 5 spheres

Since 1 cube = 20 pounds

=> From balance B:

3 cubes * 20 pounds = 5 spheres

60 pounds = 5 sphere

60 / 5 = 5 / 5

12 pounds = 1 sphere

=> From balance A:

3 cubes + 1 sphere = 1 cylinder + 2 spheres

3 spheres * 20 pounds + 1 sphere * 12 pounds = 1 cylinder + 2 spheres * 12 pounds

120 pounds + 12 pounds = 1 cylinder + 24 pounds

132 pounds = 1 cylinder + 24 pounds

132 pounds - 24 pounds = 1 cylinder + 24 pounds - 24 pounds

108 pounds = 1 cylinder
