What is the value of x in the equation 0.7x-1.4=-3.5

x = -3

Step-by-step explanation:

I searched it up 0w0

x = -3

Step-by-step explanation:

Combine multiplied terms into a single fraction

7x/10 - 1.4 = - 3.5

Add 1.4 to both sides of the equation

7x/10 - 1.4 + 1.4 = - 3.5 + 1.4

Simplify

7x/10 = - 3.5 + 1.4

7x/10 = - 2.1

Multiply all terms by the same value to eliminate fraction denominators.

10 × 7x/10 = 10(- 2.1)

Simplify

7x= 10(- 2.1)

7x = -21

-21 ÷ 7 = -3

x = -3

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
