How would you find the value of x is x equals five, in the equation...5x+29=45?

Answers

Answer 1

Answer: 5x+29 = 45
5x = 16 (subtract 29 from both sides)
x = 16/5.

That is the answer, I don't know where you got the value of 5 but it doesn't make sense. To prove it, let's try put it into the equation:

5x5 + 29 =45
25 + 29 = 45
Wrong! 25 + 29 = 54.

the expression 4X gives the perimeter of a square with a side length of X units. what is the perimeter of a square with a side length of 5/7 units?

Answers

With the equation 4x, the x represents side length. Since we are given side length of 5/7, then the equation becomes

perimeter = 4 × 5/7
p= 20/7
p= 2 6/7 units

Final answer:

The perimeter of a square with a side length of 5/7 units is 20/7 units or approximately 2.86 units.

Explanation:

The question is asking for the perimeter of a square where the side length is 5/7 units. The formula for the perimeter of a square is 4x, where 'x' is the length of the side. Thus, to get the perimeter, you substitute 5/7 for 'x' in the formula. So, 4*(5/7) = 20/7 units, which is approximately 2.86 units.

On a map, 1/4 inch represents 12 miles. If a road is 66 miles long, what is its length, in inches, on the map?

Answers

$(1)/(4)\ in\ on\ the\ map \ \rightarrow\ \ 12\ miles\n \nx\ \rightarrow\ 66\ miles\n \n12\cdot x= (1)/(4)\cdot 66\ /:12\n \n x= (33)/(2) \cdot (1)/(12) \n \nx= (3\cdot11)/(2\cdot3\cdot4) \n \nx= (11)/(8) \ [in]\n \nx=1.75\ [in]$

it'll be 1 $(5)/(6)$ inches on the map

since 12 miles is a quarter of an inch, we need to see how much it will be for 66 miles. we divide 66 by 12, which gives us 5 $(1)/(2)$

we multiply that by $(1)/(4)$ , which gives us thusly 1 $(5)/(6)$ of an inch = 66 miles.

5. Factorise: p2 - 11p +30

Answers

Answer:

(p - 5)(p - 6)

Step-by-step explanation:

Given

p² - 11p + 30

Consider the factors of the constant term (+ 30) which sum to give the coefficient of the x- term (- 11)

The factors are - 5 and - 6, since

- 5 × - 6 = + 30 and - 5 - 6 = - 11 , thus

p² - 11p + 30 = (p - 5)(p - 6) ← in factored form

Answer:

(p - 5)(p - 6)

Step-by-step explanation:

p^2 - 11p + 30

find what two numbers added together is -11 but multiplies together is 30, its' -5 and -6 so:

(p - 5)(p - 6)
