Step-by-step explanation:

Answer:

[tex]\sf (-\dfrac{4}{7} ,1\dfrac{4}{7} )[/tex]

given:

insert question 2 into 1

[tex]\sf -x + 1 = 6x + 5[/tex]

[tex]\sf -x - 6x = 5 - 1[/tex]

[tex]\sf -7x = 4[/tex]

[tex]\sf x = -\frac{4}{7}[/tex]

find the value of y:

[tex]\sf y = -x + 1[/tex]

[tex]\sf y = -\frac{-4}{7} + 1[/tex]

[tex]\sf y = \frac{4}{7} + 1[/tex]

[tex]\sf y = \frac{4}{7} +\frac{7}{7}[/tex]

[tex]\sf y = \frac{11}{7}[/tex]

[tex]\sf y = 1\frac{4}{7}[/tex]

Therefore coordinates: (x,y) = [tex]\sf (-\dfrac{4}{7} ,1\dfrac{4}{7} )[/tex]

Answer & step-by-step explanation:

Assuming the second equation is a typo and it's -2x+4y=6

No solutions. The quantity on the LHS is the same on both equation. You're basically required to find something that is at the same time equal to 5 and 6. Which is obviously impossible.

The distance from the top of the Sunshine Skyway Bridge to the boat is 305.1 feet.

The values of all trigonometric functions dependent on the value of the ratio of sides of a right-angled triangle are known as trigonometric ratios. The trigonometric ratios of a right-angled triangle's sides with regard to any of its acute angles are known as that angle's trigonometric ratios.

The three sides of the right-angled triangle are:

Hypotenuse (the longest side)

Perpendicular (opposite side to the angle)

Base (Adjacent side to the angle)

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

The trigonometry ratios for a specific angle ‘θ’ is given below:

Trigonometric Ratios:

Sin θ =  Perpendicular/Hypotenuse

Cos θ = Base/Hypotenuse

Tan θ = Perpendicular/Base or Sin θ/Cos θ

Cot θ = Base/Perpendicular or 1/tan θ

Sec θ = Hypotenuse/Base or 1/cos θ

Cosec θ = Hypotenuse/Perpendicular or 1/sin θ

Let the tower be AB = 175 feet, with the top of the tower as A.

Let the top of the boat be C. We join BC to get a right-angled triangle ABC with ∠B = 90°.

We are told that from the top of the tower, Lexi sees a boat at an angle of depression of 35°, represented as ∠CAD. ∠ACB will be equal to this angle as they are alternate angles.

∴ ∠ACB = 35°.

Let the distance from the top of the boat to the top of the tower be feet, the distance CA, the hypotenuse of the triangle ABC.

∴ By trigonometry, we can say that:

sin 35° = AB/BC

or, 0.5736 = 175/x

or, x = 175/0.5736

or, x = 305.1

∴ The distance from the top of the Sunshine Skyway Bridge to the boat is 305.1 feet.

Answer:

It's either 39.2 or 39.3 (a more accurate answer) because it depends on what you round by. since it's Delta Math, you should get 2 attempts.

Step-by-step explanation:

Since they are similar, they are proportional.

54/11=4.90909091 or 4.9

Multiply 11 by 4.90909091 and you get 54

Multiply 8 by 4.90909091 and you get 39.3

if you multiply by 4.9 you get 39.2

Step-by-step explanation:

Answer:

125 hours

Step-by-step explanation:

Lucas already has $50. Since he get $18 per hour, you should use that to get the answer. After a little while, I got 125×18 and got 2250. If you add up the $50 he already has, the minimum hours he has to work is 125 hours which is about 5 days.

Answer:

I think the answer is 125 hours

Step-by-step explanation:

To find the unit rate we divide $2300 divided by $18.00

$2300 ÷ 18 = 127.777778

We round that up to 128

We also need to find the unit rate of his saved money

$50 ÷ $18.00 = 2.77777777778

We round that up to 3

128 hours - 3 hours = 125 hours

Answer:

The equation

c x 2 > k

l x 3 ?> c > k

g = 30 = c + l + k

this equation is the same as...

Cecile read twice as many books as Kami.

Laura read 3 times as many books as Kami, but possibly less than Cecile.

Gigi read 30 books. 30 books is the same as all 3 girls combined.

To find out how many books each girl read, you need to find 3 unequal numbers that add up to 30. These numbers are substituted, only because they can be anything at all, and I want to prevent confusions.

Problem-solving is the act of defining a problem; figuring out the purpose of the trouble; identifying, prioritizing, and selecting alternatives for an answer; and imposing an answer.

Problem-solving starts with identifying the issue. As an example, a trainer may need to parent out a way to improve a scholar's overall performance on a writing talent test. To do that, the instructor will overview the writing exams looking for regions for improvement.

√b * ✓b = b (b is the answer to the question)

The ages of Fiona, Cara and Thomas is 17, 34 and 20 respectively.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Fiona who is [x] years old. Thomas is 3 years older than Fiona. Cara is twice as old as Fiona the sum of their ages is 51.

We can write -

Age of Thomas = [y] = x + 3

Age of Cara = [z] = 2x

and

2x + x = 51

3x = 51

x = 17

Age of Thomas = [y] = x + 3 = 20

Age of Cara = [z] = 2x = 34

Therefore, the ages of Fiona, Cara and Thomas is 17, 34 and 20 respectively.

Answer:

x = 10

m∠K = 90°

y = 15

JM = 65

Step-by-step explanation:

KJ = LM

⇒ x + 31 = 5x - 9

⇒ 40 = 4x

⇒ x = 10

From inspection of the diagram, m∠K = 90° (right angle)

KL = JM

⇒ 4y + 5 = 2y + 35

⇒ 2y = 30

⇒ y = 15

JM = 2y + 35

⇒ JM = 2(15) + 35

⇒ JM = 30 + 35

⇒ JM = 65
