What is the value of x?

monitta

The ans is choice D. since there nothing under 5x, imagine there is a 1 under. After that, you can simply cross multiply, so it would be 1(6+8x)= 2(5x). 6+8x= 10x now combine like terms so subtract 8x from both sides and divide 6 by 2 and you will get 3

Li walks at a constant rate of 7 ft. in 4 seconds. The table shows the relationship of feet to seconds. What is the constant of

Kisachek [45]

Answer:

The rate is 1.75 feet/seconds or 105 feet/minute.

Step-by-step explanation:

Given that,

Li walks at a constant rate of 7 feet in 4 seconds

To find the constant of proportionality, divide 7 feet by 4 seconds.

So,

$k=\dfrac{7\ \text{feet}}{4\ \text{seconds}}\\\\k=1.75\ \text{ft/s}$

1.75 ft/s is the constant of proportionality

We know that, 1 minute = 60 seconds

k = 105 feet/minute

So, the rate is 1.75 feet/seconds or 105 feet/minute.

Find the value of the remaining variable in the formula. Use 3.14 as an approximation for a (pi).

wel

Answer:

P = 12

Step-by-step explanation:

Given formula for the perimeter 'P' of a rectangle is,

P = 2L + 2W

If the values of L and W are,

L = 4 and W = 2

Perimeter of the rectangle = 2(L + W)

= 2(4 + 2)

= 2 × 6

= 12 units

Therefore, value of remaining variable 'Perimeter' = 12 units

(There is no use of 'pi' in calculating the perimeter of a rectangle).

Which expressions are equivalent to 4d+6+2d?

netineya [11]

Answer:

6d + 6 or 6(d + 1)

Step-by-step explanation:

4d + 6 + 2d

Collect like terms

4d + 2d + 6

= 6d + 6

It can also be written as

6(d + 1) by factorisation

6d + 6 or 6(d + 1)

XY is a translation of XY.

seropon [69]

Given:

The graph of a translation. X'Y' is a translation of XY.

To find:

The rule of the translation.

Solution:

Let the rule of the translation be

$(x,y)\to (x+a,y+b)$ ...(i)

So, we need to find the value of a and b.

From the given graph, it is clear that X(-4,-9) and X'(-1,0).

Using (i), the image of X(-4,-9) is

$X(-4,-9)\to X'(-4+a,-9+b)$

We have, X'(-1,0). So,

$X'(-4+a,-9+b)=X'(-1,0)$

On comparing both sides, we get

$-4+a=-1$

$a=-1+4$

$a=3$

And,

$-9+b=0$

$b=9$

So, the missing values in the rule of the translation are 3 and 9 respectively.

Therefore, the rule of translation is $(x,y)\to (x+3,y+9)$ .
