Solve for V . 7v-20=-6(v-1) Simplify your answer as much as possible.

Pavlova-9 [17]

Answer:

v = 2

Step-by-step explanation:

You can start by distributing -6:

7v - 20 = -6v + 6

To combine the like x terms, you can add 6v to both sides:

7v - 20 = -6v + 6

+6v +6v

13v - 20 = 6

Now add 20 to both sides to isolate the x term:

13v - 20 = 6

+20 +20

13v = 26

You can divide by 13 on both sides to find v,

13v = 26

÷13 ÷13

v = 2

The sides of an oblong are in the ratio of 4:3. The oblong has a length of 12 cm and is increased by a scale factor of 2.5. What

Aleksandr [31]

Answer:

If the scale factor is increased in 2.5, the increased width will be:

22.5 cm

Step-by-step explanation:

Remember that an oblong is longer than it is wide, by this reason, the ratio of 4:3 could mean, if we give a number, by each 4 cm in the length, there is 3 cm in the width, in this form, if the oblong has a length of 12 cm, the width is:

4 cm ⇒ 3 cm
12 cm ⇒ x

So:

$x=\frac{12 *3}{4}$
$x=\frac{36}{4}$
$x=9$

Then, the original width is 9 cm, as the scale factor must be increased 2.5, we can multiply the found width to obtain the increased width:

Increased width = 9 cm * 2.5
Increased width = 22.5 cm

As you can see, the increased widt will be 22.5 cm.
