Answer:

7) 230mm

8) 98m

Step-by-step explanation:

7)

7x+8+6x+6+9x-4 =22x+10

if x is 10 mm, 22(10)+10 =230mm

8) perimeter of rec =2( l + w )

=2 ( 2x-5+2x+6 ) = 8x + 2

if x  is 12 metres, 8(12)+2 =98m

Which best describes how to solve the equation for x.
prohojiy [21]

Answer:

B. multiply both sides by c.

Step-by-step explanation:

To solve the equation for x, you have to isolate the x variable on one side of the equation. To do this, do the opposite of any operation applied to x to remove other variables from the x's side of the equation:

x/c = d

multiply both sides of the equation by c to isolate x:

(x/c) * c = d * c

x = dc

Now x can be solved for.

Hope this helps :)

Answer: Part A the answer is yes and Part B the answer is no.

Step-by-step explanation:

Part A when you divide 7 by 2 you get 3.5 and if you multiply that number by the rest of the numbers and you get the number beneath the other number.

Part B when you divide 8 by 5 you get 1.6 and if you multiply that number by the rest of the numbers and then you don't get the number beneath the other number.

Can anyone help me with this ?
anygoal [31]

Answer:

The correct answer, pertaining to the proposed interrogate, is acknowledged as x = 3.

Step-by-step explanation:

To evaluate for such, a comprehension of linear data must be obtained:

Slope = rise/run, defined as the agglomerate distance between two differentiated points.

X-intercept: The peculiar point in which linear data is observed to intersect the x-axis.

Y-intercept: The peculiar point in which linear data is observed to intersect the y-axis.

If there is a vertical line intersecting the x-axis, the particular point (x, y) is identified as what x is equated to.

Likewise, if there is a horizontal line intersecting the y-axis, the particular point (x, y) is identified as what y is equated to.

Thus, the following must be applied to the interrogate:

- Vertical line, thus determine the point in which the data intersects the x-axis.

- Such is identified as (3,0).

Thus, since that is the only linear figure intersecting at such peculiar axis, 3 is the equated value of x.

Hence, x = 3.

*I hope this helps.
