Answer: X>4
Step-by-step explanation: use distributive property. -5 times X times -7. Subtract -35 from both sides. +35-35 cancels out. Subtract 35 from 15. Divide -5 from both sides. Edit: omg I just realized I didn’t change the sign!
-5x+35<15
-35<15-35
-5x<15-35
-5x<-20
x>4

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)

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
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

The length of AD is 75. Since opposite sides have the same length, 63 plus 63 is 126. The perimeter is 276, so 276 minus 126 is 150. 150 divided by 2 is 75.
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]
Walter and his mother drove to Miami Florida. It took them 9 hours and 45 minutes to drive 658.125 miles. Their average speed was how many mph?
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

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 )
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.
