What is 30 percent off of 70?

Please explain why and how

Answer:

A. -2

Step-by-step explanation:

f(x) is x+3.

When they add the number into the x part of f(x) they're just telling you to put that in for the equation

Since in this situation it's -5, all you have to do is add 3 to -5, which will result in -2.

Answer:

yuki has spent 22 percent , Rosetta spent 20 percent

step by step explanation:

1) if £100=100percent

then £22=x percent

x=(22×100)/100=22 percent

2) if £140=100 percent

then £28= x percent

x=(28×100)/140

x=2800/140

x=20 percent

Answer:

Expression after x weeks AMOUNT =$12*x

Step-by-step explanation:

Answer:

The point (0, 1) represents the y-intercept.

Hence, the y-intercept (0, 1) is on the same line.

Step-by-step explanation:

We know that the slope-intercept form of the line equation

y = mx+b

where

Given

Using the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

In our case:

substituting the values m = 2/3 and the point (-6, -3)  in the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-3\right)=\frac{2}{3}\left(x-\left(-6\right)\right)[/tex]

[tex]y+3=\frac{2}{3}\left(x+6\right)[/tex]

Subtract 3 from both sides

[tex]y+3-3=\frac{2}{3}\left(x+6\right)-3[/tex]

[tex]y=\frac{2}{3}x+4-3[/tex]

[tex]y=\frac{2}{3}x+1[/tex]

comparing with the slope-intercept form y=mx+b

Here the slope = m = 2/3

Y-intercept b = 1

We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

Given the line

[tex]y=\frac{2}{3}x+1[/tex]

at x = 0, y = 1

Thus, the point (0, 1) represents the y-intercept.

Hence, the y-intercept (0, 1) is on the same line.

The given polygons are not similar.

Given are two polygons which are similar.

For the polygons to be similar, we can write -

AB/PQ = BC/QR = CD/RS = DE/ST = AE/PT

4/8 = 3/6 = 7/15 = 10/10 = 5/10

1/2 = 1/2 ≠ 7/15 ≠ 1 ≠ 1/2

Therefore, the given polygons are not similar.

Answer:

55) m∠1 = 122°

56) m∠2 = 58°

57) m∠3 = 69°

58) m∠4 = 111°

59) m∠5 = 58°

60) m∠6 = 53°

61) m∠7 = 69°

62) m∠8 = 58°

63) m∠9 = 53°

64) m∠10 = 69°

65) m∠11 = 58°

66) m∠12 = 122°

67) m∠13 = 111°

68) m∠14 = 69°

69) m∠15 = 53°

70) m∠16 = 58°

71) m∠17 = 122°

72) m∠18 = 122°

73) m∠19 = 58°

Step-by-step explanation:

Question 56 and 67 are already given for you based on the I above.  Question 55 is 122° since m∠2 is 58° and you need 180° for a straight line.  Assuming that Question 65 and 66 are vertical to each other, it would be the same answer for 55 and 56.  Question 57 is 69° based on what is given for m∠13, same goes for Question 68.  Question 58 is the same as m∠13 for its angle.  Together m∠2 and m∠3 make up 127°, remaining is 53° for m∠6.  If z and y are congruent then m∠5 and m∠11 should also be congruent. Because m∠6 and m∠5 are given, m∠7 should be given for you in which they should all make 180°.  If line x and m are congruent then m∠18 and m∠19 should be 58° and 122° separately, ∠16 and ∠17 and vice versa. m∠5 and m∠8 should be the same. m∠7 and m∠10 should be the same and you should get the angle for m∠9.

Step-by-step explanation:

Glad you all agree

I believe that he is not correct. By him saying a number hes saying 10-5=5 but you could also do 10-0=10 so he is not correct.

Yes. Jim is correct. because a number he saying is 10-5=5 but it could also be 10-0=10.

An equation is an expression that shows the relationship between two or more numbers and variables. A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be one degree.

We have given that Jim stated, "When you subtract a number from 10, the answer will always be less than 10"

let's consider an example and say 2 is the number.

If we subtract 2 from ten, then we get 8 which is less than 10.

Therefore, if the number is greater than ten it would result in a number which less than ten

Due to this it would result in a negative number.

Hence Yes. Jim is correct. because a number he saying is 10-5=5 but it could also be 10-0=10.

Answer:

perimeter of rectangle and perimeter of triangles is 7.6 each

Step-by-step explanation:

2(7x-1.8)+2(4x+1.2)=perimeter of rectangle

6x+0.4+4x+6x+0.08=perimeter of triangle

since the perimeters are equal then

2(7x-1.8)+2(4x+1.2)=6x+0.4+4x+6x+0.8

14x-3.6+8x+2.4=16x+1.2

22x-1.2=16x+1.2

22x-16x-1.2+1.2=16x-16x+1.2+1.2

6x=2.4
