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)

To get a student learner's permit to drive in New Jersey, an individual must be at least 16 years old. Let, a, represent the age at which a person gets a student learner's permit to drive in New Jersey. Using the variable defined above, write an inequality that represents the statement above.
Answer:
[tex]a\geq 16[/tex]
Step-by-step explanation:
Let [tex]a[/tex] represents the age at which a person gets a student learner's permit to drive in New Jersey.
Also, an individual must be at least [tex]16[/tex] years old to get a student learner's permit to drive in New Jersey.
So, inequality is [tex]a\geq 16[/tex]
(Inequality explains a relationship of greater than or greater than or equal to or less than, or less than or equal to between two mathematical expressions)

The total profit function, P(x), for a company producing x thousand units is given by P(x)=−2x2+38x−120. Find the values of x for which the company makes a profit. [Hint: The company makes a profit when P(x)>0.] Explain and justify your answer.
Answer:
(5,15)
Step-by-step explanation:
Check x = 0,the P(x)=-225 : not an inequality solution
Check x = 10 to get -3*-5*5> 0 solutions in 5< x < 10
Check x = 20 to get -3*+5*+15<0 so no solutions in (15,+inf)
Ans: Profit for (5,15)

Find the value of x.
7
60°
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.

Andrew buys a laptop for $450. The store increases its purchase price by 40%? What is the new price of the laptop?
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

3. A gardener mows 5 out of every 6 days. How many days would he mow
in a 90-day period of time? Plz I really need help ASAP
Answer:
Step-by-step explanation:
90(5/6)
450/6
75
9514 1404 393
Answer:
75
Step-by-step explanation:
90 = 6 × 15
There are 15 6-day periods in 90 days. The gardener will have mowed ...
15 × 5 = 75
times in those 15 periods.
He will mow 75 times in a 90-day period.
__
If you like, you can set up a proportion for the unknown number of mowings (m).
mows/days = m/90 = 5/6
Multiply by 90 to solve for m.
m = 90(5/6) = (90/6)(5) = 15(5) = 75 . . . . . . this should look like the above

What is the value of x?
Enter
X :
(Look at the photo)
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

What is the measure of angle A?
Answer:
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 )
The figure has an area of 182 cm
Which equation can be used to find the
value of r?
A 18r + (14)(r) = 182
B 18r + -(14)(r) = 182
C 18r - -(14)(r) = 182
D 18r - (32)(r) = 182
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]
