PLEASE MARK ME AS BRAINLIEST I REALLY REALLY NEED IT PLEASEEEEEEEEEEEEE <3

Step-by-step explanation:

Answer:

Q5) x = 7

Q6) Amy is 4 years old right now

Step-by-step explanation:

Q5)

3(x+2) = 27

3x+6 = 27

subtract 6 from both sides

3x = 21

divide both sides by 3

x = 7

Q6)

P = Patel's age now

A = Amy's age now

P = A+5

P+1 = 2(A+1)

substitute for P

(A+5)+1 = 2(A+1)

reduce

A+6 = 2A+2

subtract (1)A and 2 from each side

A = 4

check:

P=A+5 = 9

9+1 = 2(4+1)

10 = 10

Answer:

630

Step-by-step explanation:

450 x 0.4 = 180

180 + 450 = 630

You can also do 450 x 1.4 = 630 because this will find the increased price with 140% of 450

Answer:

13

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (- 4, - 6) and (x₂, y₂ ) = (- 9, 6)

d = [tex]\sqrt{(-9+4)^2+(6+6)^2}[/tex]

   = [tex]\sqrt{(-5)^2+12^2}[/tex]

   = [tex]\sqrt{25+144}[/tex]

   = [tex]\sqrt{169}[/tex]

   = 13

Answer:

[tex]18r+\frac{1}{2}(14)(r)=182[/tex]

Step-by-step explanation:

Area of the composite figure ABCDE = Area of triangle ABE + Area of the rectangle BCDE

Area of triangle ABE = [tex]\frac{1}{2}(32-18)(r)[/tex]

                                  = [tex]\frac{1}{2}(14)(r)[/tex]

Area of rectangle BCDE = 18 × r

                                        = 18r

Total Area = [tex]\frac{1}{2}(14)r+18r[/tex]

Therefore, equation to get the value of 'r' will be,

[tex]18r+\frac{1}{2}(14)(r)=182[/tex]

Answer:

x = 20

Step-by-step explanation:

Each line creates a 180° angle on each side of it. Since these lines intersect, they have congruent angles. This means that these two quantities can be set equal to each other.

3x + 50 = 6x - 10

Solve by combining like-terms and isolating x. Move the 3x to the right by subtracting it from both sides.

50 = 3x - 10

Move the 10 to the left by adding it to both sides.

60 = 3x

Divide the 3 from both sides to isolate the x.

x = 20

Furthermore, this can be checked by plugging in 20 to x and seeing if the expression is true.

3(20) + 50 = 6(20) - 10

110 = 110

Answer:

Answer:

82.125

≈82.12 ( am not sure if it need to be estimated )

Step-by-step explanation:

1 hr -> 10.95

30m-> 5.475

10.95x7=76.65

76.65+5.475=82.125

                    ≈82.12 ( am not sure if it need to be estimated )

Answer:

1 quintillion and 1.

Step-by-step explanation:

This is the number written out:

1000000000000000001

The value of x is approximately (7√3) / 3.

Given that a right triangle with base = x and the perpendicular side = 7 and the reference angle is 60°, we need to find the value of x.

To find the value of x in a right triangle with a base of x and a perpendicular side of 7, and with a reference angle of 60 degrees, we can use the tangent function.

The tangent of an angle is defined as the ratio of the length of the side opposite the angle (in this case, 7) to the length of the side adjacent to the angle (in this case, x). So we have:

tan(60°) = 7 / x

Now, we can solve for x by multiplying both sides of the equation by x:

xtan(60°) = 7

To find the value of x, we need to know the value of tan(60°). The tangent of 60 degrees is √3. So we have:

x√3 = 7

To isolate x, we divide both sides of the equation by √3:

x = 7 / √3

To simplify the expression, we multiply both the numerator and the denominator by √3:

x = (7 / √3)(√3 / √3)

= (7√3) / 3

Therefore, the value of x is approximately (7√3) / 3.

Angle A is 59.5 degrees

Step-by-step explanation:

i got you!

Answer:

∠ A ≈ 59.5°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinA = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{56}{65}[/tex], then

A = [tex]sin^{-1}[/tex] ( [tex]\frac{56}{65}[/tex] ) ≈ 59.5° ( to 1 dec. place )

Answer: 67.5 mph

Step-by-step explanation:

The formula for speed is:

= Distance / Time

Distance = 658.125 miles

Time will need to be converted to a decimal. You may convert only the minutes into hours as the hours are already hours.

= 45/60 minutes

= 0.75 hrs

= 9 + 0.75

= 9.75 hours

Speed = 658.125 / 9.75

= 67.5 mph
