2x=17+1

x=18/2

x=9

Answer:

haircut =9 and hair color= 3

Step-by-step explanation:

Step one:

GIven data

let the haircut be x

and hair color be y in numbers.

so

18x+42y=288------------1

x+y=12---------------------2

from 1

x=12-y, put this in 2, we have

18(12-y)+42y=288

216-18y+42y=288

collect like terms

24y=288-216

24y=72

divide both sides by 24

y=72/24

y=3

put y= 3 in 2

x+3= 12

x= 12-3

x=9

Answer:

The correct option is (6, 0) is located on the x-axis.

Step-by-step explanation:

Given that we plot (6, 0) and (0, 5) on the xy–plane. We know that in (6, 0) 6 is the x-coordinate and 0 is the y-coordinate while in (0, 5) 0 is the x-coordinate and 5 is the y-coordinate.

Therefore, (6, 0) can be found on the x–axis not on the origin because it has shifted from 0 to 6 and (0, 5) can be found on the y-axis not on the origin because it has shifted from 0 to 5.

Hence, the correct option is (6, 0) is located on the x-axis.

Answer:

Answer:

x = 16, y = 140

Step-by-step explanation:

(8x + 12)° and (3x - 8) are adjacent angles and are supplementary, sum to 180°

8x + 12 + 3x - 8 = 180

11x + 4 = 180 ( subtract 4 from both sides )

11x = 176 ( divide both sides by 11 )

x = 16

Then

8x + 12 = 8(16) + 12 = 128 + 12 = 140

(8x + 12) and y are alternate angles and are congruent , so

y = 140

Answer:

Step-by-step explanation:

Add up the two known angle measurements. All you have to know is that all of the angles in a triangle always add up to 180°. This is true 100% of the time. So, if you know two of the three measurements of the triangle, then you're only missing one piece of the puzzle. The first thing you can do is add up the angle measurements you know. In this example, the two angle measurements you know ...

Subtract this number from 180°. The angles in a triangle add up to 180°. Therefore, the remaining an…

Answer:

70

Step-by-step explanation:

Let's say something multiplied by 60 = 4,200

We will represent something with Y

Then,

Y × 60 = 4,200

60Y = 4,200

Divide both sides by 60, then we'll have

60Y/60 = 4,200/60

Y = 4,200/60

Y = 70

Therefore, the other factor is 70

Answer:

86% of 950 is 817

Step-by-step explanation:

You convert the fraction into a decimal by moving the point two spaces to the left. You then multiply .87 by 950 to get 817

Step-by-step explanation:

Nø of sample space, n(s) = 40

nø of unripe oranges, n (u) = 12

no of ripe oranges, n (r) = 40 - 12 = 28

Now

The probability that it is ripe is, P(E)

= n(r) / n(s)

= 28 / 40

= 7 / 10

Also the probability that it is unripe is, P(E)

= n(u) / n(s)

= 12 / 40

= 3 / 10

Answer:

The ratios in the simplest form is 5:3

Step-by-step explanation:

Given that:

2.5m to 150cm

We have to express these ratios in simplest form but we will convert the quantities into same unit first.

Therefore,

Converting meters into centimeters

1 meter = 100 cm

2.5 m = 100*2.5 = 250 cm

Ratio form;

250 cm : 150 cm

As both the number are multiples of 50,

[tex]\frac{250}{50}:\frac{150}{50}\\5:3[/tex]

Hence,

The ratios in the simplest form is 5:3

12 divided by 2 is 6

x=6

To check you can do 12-2.12=9.88

Answer:Number of minutes of second  Song = 5 1/4 minutes

Number of minutes of third   Song =3 1/2  minutes

Step-by-step explanation:

Number of minutes of First Song = 3 1/2 minutes

Number of minutes of second  Song = one 1/2 times as long as her first

= 1 1/2 X 3 1/2 minutes

3/2 X 7/2

21/4 = 5 1/4 minutes

Number of minutes of third   Song = 2/3 times as long as her second song

2/ 3 x 5 1/4

= 2/3 x 21/4 =42/12

Dividing the numerator and denominator by 3 to reduce the fraction

42/ 12 / 3/3 = 14/4

14/4 = 3 2/4 = 3 1/2  minutes

Answer:

32

Step-by-step explanation:

since the question has an even number of age groups, we have to find the two middle numbers which are 30 and 34, add them together and then divide that answer by 2

30 + 34 = 64

64 ÷ 2 = 32

Answer:

Survival of the Fittest

Answer:

a rule to know: a median divides the side into equal parts.

we know:

PR = -2a + 34

SR = 2a + 26

- based on the rule, SR is half of PR. in other words, PR is two times greater than SR.

so,

2SR = PR (now simply pluggin the expressions we have)

2(2a + 26) = -2a + 34 (solve the equation like any other equation prob.)

4a + 52 = -2a + 34

6a + 52 = 34

6a = -18

a = -3

- inorder to check if this is correct, simply reverse what we did. so pluggin the value of a to see if its correct.

Step-by-step explanation:

5√2/2 is the value of x in the triangle.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The hypotanenuse is 5 cm

The angle opposite to right angle is 45 degrees.

As it is a right angle one angle is 90 degrees.

This is a right angled isosceles triangle whose sides are in the ratio 1:1:√2.

In an isosceles right triangle, the equal sides make the right angle. They have the ratio of equality, 1 : 1.

So 5/√2.

Multiply numerator and denominator by √2

We get 5√2/2

Hence, 5√2/2 is the value of x in the triangle.

Answer:

22.7604763 degrees

Step-by-step explanation:

Note that the answer is NOT 20 degrees.

She adjusted the ramp to half the original incline

Therefore we have tan 40 = x = 0.839099631.

We want an incline of y degrees where tan y = x/2 = 0.839099631/2 = 0.419549815

Taking the arctan of both sides, we get

y = arctan(0.419549815) = 22.7604763 degrees
