What is the solution to the inequality 4(2x + 2) + 12 7 100?
A x 7 10
B x 7 20
C x 7 30
D x 7 40

Answers

Answer:

x>10

Step-by-step explanation:

4(2x + 2) + 12 > 100

Subtract 12 from each side

4(2x + 2) + 12 -12> 100-12

4(2x + 2) > 88

Divide by 4

4/4(2x + 2) > 88/4

2x+2 > 22

Subtract 2

2x+2-2 > 22-2

2x> 20

Divide by 2

2x/2 >20/2

x>10

48 - 23 = d + 23 - 23

25 = d + 0

25 = d

W - 13 + 13 = 28 + 13

W + 0 = 41

W = 41

Jezebel took a train to visit her uncle. The train traveled at a constant speed of 40 miles per hour. Complete the table. Then, write an equation to find the total distance d traveled after t hours.

Answers

Answer:

[see below]

Step-by-step explanation:

We can tell that for every hour passed the distance traveled by the train would increase by 40 miles.

We can use the equation d = 40t to determine the values of the table. The 'd' is total distance and 't' is the number of given hours.

Two hours:

d = 40(2)

d = 80

Three Hours:

d = 40(3)

d = 120

Four Hours:

d = 40(4)

d = 160

Hope this helps.

Multiply 40 by that number so basically y=Mx+b

Answers

Answer: a) Surface Area : 488 [tex]cm^{2}[/tex]

Volume : 672 [tex]cm^{3}[/tex]

b) Surface Area

c) Volume

Step-by-step explanation:

The object given is a cuboid. A cuboid has 6 sides.

To calculate the surface area and volume, we need the dimensions of the cuboid which are the length(l), breadth(b), and height(h).

According to the image given, l = 14 cm, b = 8 cm, and h = 6 cm.

a) Surface Area:

The formula for the surface area of a cuboid is = 2*((l*b)+(l*h)+(b*h))

Therefore, the surface area = 2*((14*8)+(14*6)+(8*6)) = 488 [tex]cm^{2}[/tex]

The area is always denoted as [tex]cm^{2}[/tex]

Volume:

The formula for volume of a cuboid is = l*b*h

Therefore, the volume = 14*8*6 = 672 [tex]cm^{3}[/tex]

The area is always denoted as [tex]cm^{3}[/tex]

b) Plating is done to usually protect the surface area of an Object. Therefore the answer is Surface Area.

c) If the brick is made of concrete, it means that the whole space occupied by the brick consists of concrete. Therefore volume is the right option.

Answer:

Answer:

Step 1: Simplify both sides of the equation.

−40=−4n

Step 2: Flip the equation.

Solve the system of equations below by elimination. Write your answer as an ordered pair. e.g. (2,3)

Answers

Answer:

(45,35)

Step-by-step explanation:

1 - Stack the equations on top of each other

3x - 4y = -5

4x + 4y = 40

2 - We can eliminate by subtracting the bottom equation from the top equation

3x - 4y = -5

- 4x - 4y = 40

3 - The y's cancel out, leaving us with...

3x = -5

- 4x = 40

4 - Continue simplifying

-1x = -45

5 - We can switch the -1x with -x to make things simple

-x = -45

6 - Positize (make it positive) the statement

x = 45

7 - Halfway there! Substitute the x value into one of the equations

(3 * 45) - 4y = -5

8 - Solve

135 - 4y = -5

Minus 135 on both sides

-4y = -140

Divide by -4 on both sides

y = 35

9 - Here is your answer!!

x = 45

y = 35

(45,35)

Liz eams a salary of $2,400 per month, plus a commission of 4% of her sales. She wants to earn at least $2,600 this month. Enter an inequality to find amounts of sales that will meet her goal.

Answers

2400+0.04s (greater than or equal to) 2600

since we are trying to find how many sales she needs, sales would be our s. She earns 4% of her sales so to find 4% we would multiply the amount of sales by 0.04 (0.04s). She already gets $2,400 a month, so we would add that to what she makes per sale. She is trying to get at least $2,600 this month, so she needs her amount this month to be greater than or equal to $2,600. Hope this helped!!

The ice cream costs $__ for a small serving and $__ for a large serving.`

Answers

large is $4
small is $1
