What is the value of y so that the ordered pair (5, y) is a solution to the equation –5x + y = –40?

Answers

Answer 1

Answer: (5, y). Implies that x = 5

-5x + y = -40

-5*5 + y = -40

-25 + y = -40

y = -40 + 25

y = 25 - 40

y = -15.

Value of y = -15.

Answer 2

Answer: I'm a little confused with the question but if u want to find the value for y so u can get -40 is going to be -35
-5x+y=-40
-5(1)+y(-35)=-40
-5-35=-40

Factorise x² + 4x + 3.I understand everything perfectly until I have to split the two sections, add up and pull out the common factors: x² + 3x: common factor is x 1x + 3: common factor is 1 From here I do not understand how you get to the answer which I do know is (x + 1) • (x + 3). None of the explanations out there give detail to this step. I don’t understand how adding those two groups up (while pulling out common factors) will give you (x + 1) • (x + 3)! I would hugely appreciate any help on this! Thank you :)

60% of what number is 72?

Answers

$60%=0.6$

$0.6*x=72$

$0.6x=72$

$x= (72)/(0.6)$

$x=120$

72 is 60% of 120

60 percent of 120 is equal to 72.

We have,

To find the number that corresponds to 60% of a given value, we can set up an equation and solve for the unknown number.

Let's represent the unknown number as "x."

The problem states that 60% (or 0.6 as a decimal) of that number is equal to 72.

0.6x = 72

To isolate "x," we divide both sides of the equation by 0.6:

x = 72 / 0.6

Performing the division:

x = 120

Therefore,

60% of 120 is equal to 72.

How many sides does a polygon have if the sum of its angle measures is 2700 degrees and how do you find this?

Answers

$the\ sum\ of\ angle\ measures\ is\ 2700^0\n\n(n-2)\cdot180^0=2700^0\nn-the\ number\ of\ the\ sides\ of\ the\ polygon\n\nn-2= (2700)/(180) \ \ \ \Rightarrow\ \ \ n-2=15\ \ \ \Rightarrow\ \ \ n=17\n\nAns.\ 17\ sides\ of\ the\ polygon.$

The number of angles equal the number of sides

The number of angles calculate: (n-2)x180°

(n-2)x180°=2700° |divide both sides by 180°

n-2=15 |add 2 to both siedes

n=13

Answer: 13 sides.
