An equilateral triangle has a perimeter of
24x + 6. What is the length of one side of the triangle?

Answers

Answer:

8x + 2

Step-by-step explanation:

The 3 sides of an equilateral triangle are congruent.

Divide the perimeter by 3 to find length of one side

[tex]\frac{24x+6}{3}[/tex]

= [tex]\frac{24x}{3}[/tex] + [tex]\frac{6}{3}[/tex]

= 8x + 2

Answer: if these expression represent side lengths, then you simply add those three expressions, and that's the perimeter.

Find the Value of x




A. 18
B. 7
C. 25
D. 11

Answers

Answer:

B - x = 7

Explanation:

5x + 55 = 90

5x = 35

x = 7

Answer: x = 7

Step-by-step explanation:

Put both angles in an equation that equals 90 degrees

5x + 55 = 90

subtract 55 from both sides

5x = 35

divide by 5

x = 7

Now check if its true.

5(7) + 55 = 90

35 + 55 = 90

Statement is true meaning x is 7

Linda has to buy stickers, erasers, and a pencil. She can only spend $3. A sticker costs $0.35, an eraser costs $0.99, and a pencil costs $0.59. Can Linda buy 3 stickers and 2 erasers?

[Use the inequality 0.35x + 0.99y + 0.59 ≤ 3]

Yes, because the total will be $1.62
Yes, because the total will be $2.93
No, because the total will be $3.62
No, because the total will be $5.93

Answers

Answer:

No, because the total will be 3.03 + 0.59 = £3.62

Step-by-step explanation:

0.35 x 3 = 1.05

0.99 x 2 = 1.98

1.05 + 1.98 = 3.03 = $3.03 without pencil (0.59)

= 1.05 + 1.98 = 3.03 ≤ 3 is incorrect as 3.03 should be the maximum equal to or appear the other way round.

Inequality for all 6 items using the same inequality shown 0.35x+0.99y+0.59< 3 is incorrect No, because the total will be 3.03 + 0.59 = £3.62

and inequality of higher amounts than $3 should be shown other way round where ≤ 3 means it stops at $3 and is less or equal.

and inequality facing towards means it would be equal but more than $3
