To find three consecutive odd integers that have a sum of 63

2 answers:

8 0

Since we are finding the sum of three consecutive odd integers, we will be skipping our even numbers so we can set up an equation.

X + X + 2 + X + 4 = 63

Now, since we have 3 X's on the same side, we can combine them. We can also combine 4 and 2 together to get 6.

<h2>3x + 6 = 63</h2><h2> -6 -6 ← subtract 6 on both sides</h2><h2 /><h2 /><h2>3x = 57</h2><h2>÷3 ÷3</h2><h2 /><h2>X = 19</h2><h2>X + 2 = 21</h2><h2>X + 4 = 23</h2><h2 /><h3>Therefore, our three consecutive odd integers are 19, 21, and 23.</h3>

John has less than 15 video games what is the inequality?

lidiya [134]

Answer: well, we don't have another number so i'll use variables

VG < 15

An easy way to remember what is the lesser value is to think of an alligator; the alligator wants to eat the bigger prey so in your case the bigger prey would be 15.

The total surface area of this cuboid is 112cm^2. Find the value of x.

Oxana [17]

Answer:

The value of x is 3

Step-by-step explanation:

Let us study the face of the cuboind

∵ The cuboid has 6 rectangular faces

∵ Each opposite faces area equal in areas

∴ 2 faces of dimensions 10 cm and 2 cm

∴ 2 faces of dimensions 10 cm and x cm

∴ 2 faces of dimensions 2 cm and x cm

∵ The total surface area of the cuboid is the sum of the areas of the 6 faces

∵ The area of the rectangle = length × width

∴ The total surface area = 2(10 × 2) + 2(10 × x) + 2(2 × x)

∴ The total surface area = 2(20) + 2(10x) + 2(2x)

∴ The total surface area = 40 + 20x + 4x

→ Add the like terms 20x and 4x

∴ The total surface area = 40 + 24x

∵ The total surface area of this cuboid is 112 cm²

→ Equate the two sides of the total surface area

∴ 40 + 24x = 112

→ Subtract 40 from both sides

∵ 40 - 40 + 24x = 112 - 40

∴ 24x = 72

→ Divide both sides by 24

∴ x = 3

∴ The value of x is 3
