Answer:

Thus, the value of x = -36 when y = 15

Step-by-step explanation:

We know that if y varies directly with x, we can express the relationship such as

y ∝ x

y = kx

k = y/x

where 'k' is called constant of variation.

Given

y = -5

x = 12

Using the equation

k = y/x = -5/12

Thus, the value of k = -5/12

Finding x when y = 15

y = 15

k = -5/12

substituting y = 15 and k = -5/12 in the equation

y = kx

15 = -5/12 (x)

15×12 = -5x

180 = -5x

divding both sides by -5

-5x/-5 = 180/-5

x = -36

Thus, the value of x = -36 when y = 15

Answer:

44

Step-by-step explanation:

Given that:

Fiona, Peter and Angad share some sweets in the ratio 5:4:3. Fiona gets 22 more

sweets than Angad. How many sweets does Peter get?

5 : 4 : 3

Total ratio = (5 + 4 + 3) = 12

Let total number of sweets = x

For Fiona :

(5 / 12) * x = 5x / 12

Peter :

(4 / 12) * x = 4x / 12

Angad:

(3 / 12) * x = 3x / 12

Sunce, Fiona gets 22 more Than Angad ;

Then;

5x / 12 = 22 + 3x /12

5x/12 = 22 + 3x/12

5x/12 - 3x/12 = 22

(5x - 3x) / 12 = 22

2x / 12 = 22

2x = 22 * 12

2x = 264

x = 132

Hence, total number of sweets = 132

Peter's share = (4x / 12) = (4 * 132) / 12 = 528/12 = 44

Peter got 44 sweets

Answer:

Slope is -2/5 and y-intercept is -1/3

Step-by-step explanation:

To get the slope, we pick any two points and apply the slope formula

The slope formula is;

m = (y2-y1)/(x2-x1)

To get the slope, we select any two points

That will be;

(-3/4, -1/30) and (1/4,-13/30)

Substituting these in the slope formula, we have:

m = (-13/30 + 1/30)/(1/4 + 3/4)

m = 12/30 = -2/5

Generally, the equation of a straight line is;

y = mx + b

m is slope and b is the y-intercept

We already have the slope, to get the y-intercept, we select any of the points

-3/5 = -2/5(2/3) + b

= -3/5 + 4/15 = b

b = (-9 + 4)/15 = -5/15 = -1/3

Slope is -2/5 and y-intercept is -1/3

Answer:

A

Step-by-step explanation:

The slope is -2/5, and the y-intercept is -1/3.

Answer:

B cuz both can be divided by 7

Answer:

$0.02

Step-by-step explanation:

This is the correct way to do 2 cents. Since two is not in the tenths place, and is not yet a dollar, the correct answer is $0.02.

Hope this helps! :D

The representation of 2 cents in dollar sign will be $0.02.

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

It is known that,

$1 = 100 cents

Divide both sides by 100

$1/100 = 1 cents

Multiply by 2 on both sides,

$(1/100)2 = 2 cents

$0.02 = 2 cents

Hence "The representation of 2 cents in dollar sign will be $0.02".

Step-by-step explanation:

Answer: 5/8

Step-by-step explanation:

Number of green jelly beans = 3

Number of red jelly beans = 5

Total number of jelly beans = 3 + 5 = 8

The probability of selecting a red jelly bean would be:

= Number of red jelly beans /:Total number of jelly beans

= 5/8

total number of marbles= 5+2+3+5 = 15 marbles

probability of a red marble - 2/15

probability of yellow marble - 5/15 = 1/3

Answer:

i) 2/15 ii) 1/3

Step-by-step explanation:

the number of marbles all together is 15

2 out of the 15 are red, so 2/15

5 out of 15 are yellow,so 5/15, simplified to 1/3

Answer: b. Every 18 minutes, 28 more pizzas were set out on the buffet.

Step-by-step explanation:

The equation is in the form: y = mx + c

m is the gradient which represents the rate of change per a given value of x.

x here is every 9 minutes after 11:00. Every 18 minutes therefore will give x a value of 2 because 18/9 = 2.

The rate of change every 18 minutes is therefore;

= 14 * 2

= 28 pizzas

Answer:

The girl was 144cm tall

Step-by-step explanation:

Total height of the three boys=3×156=468

Total height of the four children=4×153=612

Height of the girl=612-468=144cm

The average height of 3 boys was 156cm. Therefore, The girl was 144cm tall.

Let the thing that is changing be y and the thing with which the rate is being compared is x, then we have the average rate of change of y as x changes as:

[tex]\text{Average rate} = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]

The average height of 3 boys was 156cm.

When a girl joined them, the average height of the 4 children was 153cm.

Total height of the three boys = 3 × 156 = 468

Total height of the four children = 4 × 153 = 612

Height of the girl  = 612 - 468 = 144cm

Hence, the girl was 144cm tall.

17. [tex]x = 55, y =70, z = 55[/tex]

18. [tex]x =8, y =3[/tex]

19. [tex]r = 66^\circ[/tex], [tex]t = 73^\circ[/tex]

20. [tex]y = 70^\circ, x = 55^\circ[/tex]

21. [tex]x =56^\circ, y = 62^\circ[/tex]

Step-by-step explanation:

16. Side [tex]AB = AC[/tex]

So, the opposite angles of the triangle will also be equal.

[tex]\angle B =\angle C = 50^\circ[/tex]

Using triangle sum property, angle of all the internal angles of a triangle is equal to [tex]180^\circ[/tex].

[tex]50+50+x = 180\\\Rightarrow x = \bold{80^\circ}[/tex]

17. Two sides are given as equal, [tex]x = z[/tex]

Angles on a straight line are always equal to [tex]180^\circ[/tex].

So,

[tex]x + 125 = 180\\\Rightarrow x = 55[/tex]

[tex]z = 55[/tex]

Using triangle sum property, angle of all the internal angles of a triangle is equal to [tex]180^\circ[/tex].

[tex]55+55+y = 180\\\Rightarrow y = \bold{70^\circ}[/tex]

18. All the angles are given equal to each other, therefore all the sides of the triangle will also be equal to each other.

[tex]4x+7 = 13y =39[/tex]

[tex]13y = 39\\\Rightarrow y = 3[/tex]

[tex]4x +7 = 39\\\Rightarrow 4x = 32\\\Rightarrow x = 8[/tex]

19. Two sides are given equal to each other, therefore angles opposite to them will be equal.

Using the triangle sum property in the left triangle:

[tex]r + 57 + 57 = 180\\\Rightarrow r = 66^\circ[/tex]

Using the property that vertically opposite angles are equal and the triangle sum property in the right triangle.

[tex]t+50+57 = 180 \\\Rightarrow t = 73^\circ[/tex]

20. All the sides are given equal to each other.

So, all the angles will be equal to [tex]60^\circ[/tex].

[tex]y - 10 = 60\\\Rightarrow y = 70^\circ[/tex]

[tex]x+5=60\\\Rightarrow x = 55^\circ[/tex]

21. Angles on a straight line are always equal to [tex]180^\circ[/tex].

Angles opposite to equal sides in a triangle are also equal.

[tex]118 + y = 180\\\Rightarrow y = 62^\circ[/tex]

Using triangle sum property:

[tex]x+2y = 180\\\Rightarrow x = 180 - 124 = \bold{56^\circ}[/tex]

Given:

[tex]0.5(4x-8)+11=0.25(12x+20)-5[/tex]

To find:

The value of x.

Solution:

We have,

[tex]0.5(4x-8)+11=0.25(12x+20)-5[/tex]

Using distributive property, we get

[tex]0.5(4x)+0.5(-8)+11=0.25(12x)+0.25(20)-5[/tex]

[tex]2x-4+11=3x+5-5[/tex]

[tex]2x+7=3x[/tex]

Subtract 2x from both sides.

[tex]7=3x-2x[/tex]

[tex]7=x[/tex]

Therefore, the value of x is 7.

Answer:

8 hours

Step-by-step explanation:

In the problem, it gives you the formula: d=rt, and in the rest of the problem it gives you the distance and the rate, so all you have to do is plug the numbers in and solve.

360m = 45mph(t)

Isolate the variable by dividing 360 by 45

360/45 = t

8 = t

This means that it will take 8 hours to travel 360 miles at a rate of 45 miles per hour.
