$\frac{x}{2} -18=-28$ Add 18 on both sides

$\frac{x}{2} -18+18=-28+18$

$\frac{x}{2}=-10$ Multiply 2 on both sides

$(2)\frac{x}{2} =-10(2)$

x = -20

[proof]

$\frac{x}{2} -18=-28$

$\frac{-20}{2}-18=-28$

-10 - 18 = -28

-28 = -28

Find the value of each variable and the measure of each labeled angle.

labwork [276]

Answer:

see explanation

Step-by-step explanation:

(8x - 75) and (5x) are vertically opposite angles and are congruent , then

8x - 75 = 5x ( subtract 5x from both sides )

3x - 75 = 0 ( add 75 to both sides )

3x = 75 ( divide both sides by 3 )

x = 25

Then

5x = 5(25) = 125°

8x - 75 = 8(25) - 75 = 200 - 75 = 125°

When this 'L'-shape is rotated about the origin (0,0) by 90° counter-clockwise, which one of these would it look like?

Yuliya22 [10]

The "L"-shape would look like it fell backwards and was laying on the ground. The little leg of the L would be pointing up into the air.

A 90 degree counter clockwise turn means that it rotates left around the origin. It turns one half of half a turn, or 90 degrees.

(iii) Show it in a Venn diagram. In a survey of 120 students, 60 drink milk, 50 drink curd and 20 students drink milk as well cu

Step2247 [10]

Answer:

Step-by-step explanation:

As you can see in the venn diagram that is attached below, The individuals that drink milk are in green, those that drink curd are in yellow, and those that drink both are in light blue. Since the sum of those that drink milk with those that drink curd is 110 and a total of 120 students were surveryed. Then this means that 10 of the students neither drink milk nor curd. These students are represented outside of the venn diagram but within the box of surveyed students.
