In order to get the answer to this question, we first have to subtract 350 and 70 in order to get the unit change of the two numbers. So after subtracting 350 and 70, we will get an answer of 280. After that, we simply divide 280 with 350 in order to get the percentage of change. After division, we will get an answer of 0.8. In order to get the percentage form of that value, we will just multiply 0.8 with 100 to get 80 or 80%

A formula is given as J = 10V/11 + 143

Nadusha1986 [10]

Answer:

11j - 1573/10

Step-by-step explanation:

J = 10v /11 +143

collect terms

J - 143 =10v /11

11 (J -143) = 10v

Divide both sides by 10

11(J - 143)/10 = v

v = 11J - 1573/10

Hope this helps!

If PR = 4x – 2 and RS = 3x – 5, which expression represents PS?

seropon [69]

Answer:

$7x-7$

Step-by-step explanation:

We have been given that $PR=4x-2$ and $RS=3x-5$ . We are asked to find the expression that represents length of PS.

We know that $PS=PR+RS$ .

Upon substituting our given values in above equation, we will get:

$PS=4x-2+(3x-5)$

$PS=4x-2+3x-5$

$PS=4x+3x-2-5$

$PS=7x-7$

Therefore, the expression $7x-7$ represents length of PS.

Please answer correctly !!!!! Will mark brainliest !!!!!!!!!!

Sever21 [200]

Answer:

Exactly one solution

Step-by-step explanation:

4x -2y = 8

2x +y = 2

Multiply the second equation by 2

4x +2y = 4

Add the two equations together

4x -2y = 8

4x +2y = 4

-------------------

8x = 12

x = 12/8

We know there will be one solution

What geometric shape may describe a quadrilateral that has exactly two pairs of parallel sides and no right angles? (If you don’

Ilya [14]

The answer is a parallelogram. Quadrilateral have 4 sides, and if there are not right angles, it cannot be a rectangle because that is the added characteristic of rectangles. All rectangles are actually parallelograms, but only parallelograms will have exactly 2 pairs of parallel sides with no right angles. The statement says "may" because as I mentioned before, rectangles are parallelograms too!
