Jayden used the multiplication table below to determine that 8:14 is equivalent to 24:42.

Which statement explains why Jayden’s reasoning is correct?

a. The ratio 8:14 is 4:7 times 2, and the ratio 24:42 is 4:7 times 6.
b. The terms 8 and 14 are multiples of 2, and the terms 24 and 42 are also multiples of 2 when the table is extended.
c. The term 24 is a multiple of the term 8, and the terms 14 and 42 are multiples of 7.
d. The ratio 8:14 is equivalent to 2:7, and the ratio 24:42 is also equivalent to 2:

Answer:

Both -6x +7>-5 and 14x-2<12

Step-by-step explanation:

Your question said "Which of the FOLLOWING inequalities require the inequality symbol to be reversed when solving" I hope this means multiple choice because i got both 14x-2<12 and -6x +7>-5 to be reversed when i finished solving them. For 6x +7>-5 I got X < 2, and for 14x-2<12 I got X > -28, therefore those two are correct.

-0.58333333333 that's what i got

Step-by-step explanation:

Answer:

1/5 of $28 is $5.60 so $28 - $5.60 = $22.40

Answer:

x = 2

Step-by-step explanation:

The parallel lines divide the transversals in proportion, that is

[tex]\frac{x}{8}[/tex] = [tex]\frac{9}{36}[/tex] = [tex]\frac{1}{4}[/tex] ( cross- multiply )

4x = 8 ( divide both sides by 4 )

x = 2

Answer:

There are four (4) different terms

Step-by-step explanation:

Given;

2x + 3xy - (x + y) + 2

The terms are simplified as follows;

=2x + 3xy - (x + y) + 2

= 2x + 3xy - x - y + 2

collect like terms;

= 2x - x  - y + 3xy + 2

= x - y + 3xy  + 2

Thus, there are four (4) different terms in the simplified expression.

i dont know how to solve for a unit rate, its a ration but, sorry

Answer:

7/9

Step-by-step explanation:

5 5/6 equals 35/6. 7 1/2 is equal to 15/2.

Then you do 35/6 times 2/15. You flip the 15/2 to get 2/15.

35/6 times 2/15 is 70/90 which equals 7/9.

Hope this helps :)

Step-by-step explanation:

this is an isosceles triangle, 2 sides are equal

the other angle is also 55

x=180-(55+55)=180-110=70

the initial value is -1

Answer:

$539.00

Step-by-step explanation:

K=98

El=3K    3*98=294

Em=.5El  294*.5=147

K+El+Em=98+294+147=539

Answer:

$539

Step-by-step explanation:

First we need to look at the information given

Karen: $98.00

Emily: Karen x 3

Elizabeth: Emily /2

So if karen donated $98 and emily donated 3 times that all we need to do is multiply it by 3

$98*3= $294

So we now know that Emily donated $294

If Emily donated $294 and elizabeth donated half that all we need to do is divide $294 by 2

$294/2= $147

So we now know that Elizabeth donated $147

All we need to do know is add all three answers together $98+$294+$147=

$539

Answer:

-72

Answer:

what are you looking for? the value of y or x? or do you need it graphed?

Step-by-step explanation:

Answer:

Please check the explanation.

Step-by-step explanation:

Given that

[tex]m=-1[/tex]

point = (2, 4) has the x-coordinate x=2, and y-coordinate y=4

Now, fill in the blanks:

y = __4__     ,      m = __-1__     ,    and     x = __2__

[tex]y=mx+b[/tex]

_4_ = -1 (__2__)+b

_4_ = _-2_ + b

_6_ = b

The y-intercept is _6_.

The equation of the line is y = _-1_ x + _6_

9514 1404 393

Answer:

Step-by-step explanation:

The height equation tells you the height increases 4 feet every time x (seconds) increases by 1. The rate of increase of height is 4 ft/second.

The equation also tells you the height is 3 feet at time = 0. That is, the initial height is 3 feet.

Answer:

x=29

Step-by-step explanation:

because the two sides of the acute triangle are the same length, the ones at the bottom are the same as well. the total of the angles of a triangle is 180, and we know that one of the angles are 64 so we subtract that from 180 and get 116 which we divide by two to get the other two angles: 58 and 58. at the bottom of the image, two angles are connected and make a straight 180 line so we can take 58 out of that 180 and get 122 in the obtuse angle and divide by two to get 29 in the acute angles of the obtuse triangle.

Answer:

y=x+4

Step-by-step explanation:

Answer:

Step-by-step explanation:

Find the diagram attached.

Given the scale factor of circle A to circle B as 3/4

A:B = 3:4

Total ratio = 3+4 = 7

Area of bigger square A = 45sq. units;

The Total area can be gotten using the expression;

[tex]\frac{4}{7} \times x = 45[/tex] where;

x is the total area of both circles.

Get x;

[tex]\frac{4}{7} \times x = 45\\4x = 7 \times 45\\4x = 315\\x = \frac{315}{4}\\x = 78.75[/tex]

Area of circle B = 78.75 - 45 = 33.75

Let the fraction required be y

45 * y = 33.75

y = 33.75/45

y = 3375/4500

y = 45/60

y = 3/4

Hence the area of circle B is 45 * 3/4 of circle A

b)The ratio of circle A to Circle B is expressed as;

Ratio = Area of circle A/Area of circle B

Ratio = 45/33.75

Ratio = 45 * 100/3375

ratio = 4500/3375

Ratio = 4:3

Hence the ratio of circle A to Circle B is 4:3
