Answer:

x = 12

Step-by-step explanation:

First, eliminate the fractional coefficient 1/2, by multiplying all three terms by 2:

-24 + x = -12

Adding 24 to both sides isolates x:  x = -12 + 24, or x = 12

Answer: As we know that, Probability of an event =Number of favourable cases Number of total cases, We get, probability of choosing a prime number from 1 to 20 =820=25. Therefore, we get the probability of choosing a prime number from 1 to 20 as 25or 0.4.

Answer:

hope this helps you!

Step-by-step explanation:

(3, 8.5) is the answer

Step-by-step explanation:

slope of the given line=2/3

since the required line is parallel to the given line, it's slope will be same.

hence slope of required line:2/3

The required line passes through the point(9,1),

hence the equation of the required line,

y-1=(2/3)(x-9)

3y-3=2x-18

2x-3y-15=0

There the equation of the required line is 2x-3y-15=0

Answer: 5

Step-by-step explanation: 6-1=5

Answer:

x=5

Step-by-step explanation:

To get the x alone, you would have to get the one away. To do that, you will have to get it to 0, by subtracting 1 from 6, making it five. Now x is alone like this: x=5

There's your answer

Answer:

Yes you are right.

Step-by-step explanation:

Once you divide 128.25 by 3 you will get 42.75

Then you multiply 42.75 by 5 and you will get 213.75.

Answer:

y=10 when x=7

Step-by-step explanation:

y=2x-4

y=10

Substitute y with "10": 10=2x-4

Add 4 on both sides: 14=2x

x=7

Answer:

substitute 10 for y in the equation y=2x-4

10=2x-4

2x=10+4

2x=6

divide both side by 2

x=3

Answer:

C. x - 5y - 30 = 0

Step-by-step explanation:

Y = x/5 - 30

y + 30 = x/5

you multiply both sides by 5

5y + 30 = x

you subtract x from both sides

- x + 5y + 30 = 0

which is the same as

x - 5y - 30 = 0

Answer:

144 square foot

Step-by-step explanation:

Area of rectangle: Length × breadth

Area of rectangle = 16 × 9

                             = 144 square foot

The required fill-in-the-blank below as:

1.) ZW ⊥ XW, ZW ⊥ WY, ∠ ZXV ≅ ∠ YXV | Given

2.) XV≅XV | Reflexive Property

3). SAS Triangle Congruence Property

Two triangles are said to be congruent if their corresponding sides and angles are equal.

The given in question as:

WX bisects ZXY,

ŽX =YX

To prove:

△ZXV ≅ △YXV

1.) ZW ⊥ XW, ZW ⊥ WY, ∠ ZXV ≅ ∠ YXV | Given

2.) XV≅XV | Reflexive Property

According to SAS, two triangles are congruent if the two sides and the included angle of one triangle are equal to the corresponding sides and the included angle of the other triangle.

3). SAS Triangle Congruence Property

Hence, △ZXV ≅ △YXV

Thus, the required fill-in-the-blank above is in the solution.

Answer:

Small flags = 108

large flags= 47

Step-by-step explanation:

Step one:

given

let the number of small lag be x

and big flags be y

so

3.5x+6.5y= 683.5----------1

x+y=155------------------------2

Step two:

from eqn 2 x= 155-y

put x= 155-y in  eqn 1

3.5(155-y)+6.5y= 683.5

542.5-3.5y+6.5y=683.5

collect like terms

3y=141

divide by 3

y= 141/3

y=47

Step three:

put y= 47 in eqn 2

x+47=155

x= 155-47

x=108

Answer:

$105.00 is the answer subtract 45 $

Answer:

the item should cost $105

Step-by-step explanation:

its very simple just put 150 and it by 30% and its 105

150÷30%=105

Christina B. asked • 11/16/20

please help me i've been stuck on this question forever

Write a system of equations to describe the situation below, solve, and write as an ordered pair (with number of months as x). Two friends, Ann and Malia, are growing out their hair. They plan to cut it off at a certain point and donate it to a charity that makes wigs for people with cancer. Ann's hair is already 23 centimeters long and grows at a constant rate of 3 centimeters per month. Malia's hair is 27 centimeters and growing at a speed of 1 centimeter per month. If the girls get their hair cut on a certain day, they will have exactly the same length to donate. How long will their hair be? How long will that take?

Ann's hair length: y = 23 + 3x

Malia's hair length: y = 27 + x

Thus: 23 + 3x = 27 + x

23 + 2x = 27

2x = 4

x = 2

Ann's hair length: y = 23 + 2(3) = 29

Malia's Hair length: y = 27 + 2 = 29

Solution: (x, y) = (2, 29)

In 2 months both Ann's and Malia's hair will be 29 centimeters long.

Let's start with Ann's hair: 23 centimeters + 3 centimeters per month

Malia's hair: 27 centimeters + 1 centimeter per month

Now we can substitute the number of months for "x"

Ann's hair length = 23 + 3x

Malia's hair length = 27 +1x

We know that we want both girls to have the same hair length at the end so we can set these two equations as equal to each other:

23 + 3x = 27 + 1x Subtract 23 from both sides

3x = 4 + 1x Subtract 1x from both sides

2x = 4 Divide by 2

x=2 Now we know it will take 2 months for their hair to be the same length!

Let's plug that in to our original equations:

Ann's hair length = 23 + 3(2) = 29 centimeters

Malia's hair = 27 + 1(2) = 29 centimeters

It will take 2 months for the girls to grow their hair to the same length of 29 centimeters.

As ordered pairs, with x as the number of months, we can use the length of the girls hair as the y value.

At 0 months, Ann's hair is 23 cm and Malia's is 27 cm so the first ordered pairs are (0, 23) and (0, 27).

At 1 month, Ann's hair grows 3 cm and Malia's grows 1 cm so the second pairs are (1, 26) and (1, 28).

Finally, at 2 months Ann's hair is at 29 cm and so is Malia's so the final ordered pair is (2, 29) for both girls.

If you were to draw these equations on a graph, (2, 29) is where the lines would intersect.

Answer:

4/9ths of a cup of sugar is needed for one cup of flour.

Step-by-step explanation:

To answer this you need to scale the number of cups of flour up from 3/4 to 1  that ratio would be 4/3 (multiplying a fraction by its own reciprocal will give you 1).

We can then simply take that ratio, and scale the sugar by the same amount:

1/3 * 4/3 = 4/9

Answer:

0.4 (not rounded)

Step-by-step explanation

You can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 18 and 45 using

GCF(18,45) = 9

18÷945÷9=25

We know that

25

is the same as

2÷5

Then using

Long Division for 2 divided by 5

gives us

=0.4
