Which expression has a value equal to 28 ÷ 4​

Answer:

Step-by-step explanation:

D:  x ≥ -2.  This set includes x = -2 and all numbers greater than -2.

Answer: Choice D)  [tex]x \ge -2[/tex]

Explanation:

We have a closed circle at -2, and shading to the right. This tells us x can equal -2, or it can be larger than -2. In short, x is greater than or equal to -2.

Symbolically, we'd write it as [tex]x \ge -2[/tex]

If you wanted to graph [tex]x > -2[/tex] instead, you would have an open circle to indicate "do not include this value in the solution set".

Answer:-4-9

Step-by-step explanation:

Answer:

60

Step-by-step explanation:

The expression Mrs. Clements use to find the area of the tabletop, in square feet is  0.5 * (5 + 9) * 4

The dimension of the tabletop is:

Parallel sides = 5 feet and 9 feet

Height = 4 feet

The area is then calculated using:

Area = 0.5 * (Sum of parallel sides) * Height

This gives

Area = 0.5 * (5 + 9) * 4

Hence, the expression Mrs. Clements use to find the area of the tabletop, in square feet is  0.5 * (5 + 9) * 4

Answer:

Using Pythagorean theorem

c=(8)²+(2)²

√c²=√68

c=2√17 or √68

d²=(2√17)²+(5)²

d²=68+25

√d²=√93

d=√93 or 9.6

4 = 74

Step-by-step explanation:

Vertical angles congruent and supplementry angles theorm

Answer:

∠2 = 74º

∠3 = 106º

∠4 = 74º

Step-by-step explanation:

∠2 is supplementary to ∠1

∠2 = 180 - 106

∠2 = 74º

-----------------------------

∠3 is a vertical angle to ∠1

∠3 = ∠1

∠3 = 106º

∠4  is a vertical angle to ∠2

∠4 = ∠2

∠4 = 74º

Answer:

13 white cars

Step-by-step explanation:

Let us represent:

Number of

Red cars = x

Blue cars = y

White cars = z

Sharon has 23 toy car that are colored red, blue, and white.

x + y + z = 23

x = 4

2 fewer blue cars than red

y - 2 = x

y - 2 = 4

y = 4 + 2

y = 6

Hence,

x + y + z = 23

4 +

Number of white cars is calculated as:

23 - (6 + 4)

23 - 10

= 13 white cars

Answer:

x = -14/5

Step-by-step explanation:

Given: 8^(3x+4) = 4^(2x-1)

Rewrite with same base: (2^3)^(3x+4) = (2^2)^(2x-1)

Use exponent rules: 2^(3(3x+4)) = 2^(2(2x-1))

Eliminate bases: 3(3x+4) = 2(2x-1)

9x+12 = 4x-2

5x+12 = -2

5x = -14

x = -14/5

Answer:

School A sent 55 kids, School B sent 110 kids, & School C sent 52 kids.

Step-by-step explanation:

A = x kids

B = 2x kids

C = x-3 kids

Each kid pays $10, so multiply 10 by the amount of students from each school.

$2170 was payed in total.

So,

2170 = 10(x) + 10(2x) + 10(x-3)

Un-distribute the 10...

2170 = 10 (x + 2x + x - 3)

Divide both sides by 10...

217 = x + 2x + x - 3

Add 3...

220 = x + 2x + x

Combine like terms...

220 = 4x

Divide by 4...

x = 55

Go back to your original equations... plug in 55 for x.

A = (55) kids

B = 2(55) kids

C = (55)-3 kids

Answer:

1.) The 1ˢᵗ three term is (-32), (-7) and 18

2.) The 1ˢᵗ three term is 127, 106 and 85

Step-by-step explanation:

Here,

First Term = a₁ = - 32

Common Difference = (d) = 25

Now, For 1ˢᵗ three term,

n = 1

a₁ = - 32

n = 2

aₙ = a + (n - 1)d

a₂ = (-32) + (2 - 1) × 25

a₂ = (-32) + 1 × 25

a₂ = (-32) + 25

a₂ = -7

n = 3

aₙ = a + (n - 1)d

a₃ = (-32) + (3 - 1) × 25

a₃ = (-32) + 2 × 25

a₃ = (-32) + 50

a₃ = 18

Thus, The 1ˢᵗ three term is (-32), (-7) and 18

Here,

First Term = a₁ = 127

Common Difference = (d) = -21

Now, For 1ˢᵗ three term,

n = 1

a₁ = 127

n = 2

aₙ = a + (n - 1)d

a₂ = 127 + (2 - 1) × (-21)

a₂ = 127 + 1 × (-21)

a₂ = 127 - 21

a₂ = 106

n = 3

aₙ = a + (n - 1)d

a₃ = 127 + (3 - 1) × (-21)

a₃ = 127 + 2 × (-21)

a₃ = 127 - 42

a₃ = 85

Thus, The 1ˢᵗ three term is 127, 106 and 85
