Three times the difference of a number and 7 is 30. Find the number.
Answer:
x = 17Step-by-step explanation:
3(x - 7) = 30 is our equation, since we take 7 away from the number and then multiply the result by 3.
3x - 21 = 30
Add 21
3x = 51
Divide by 3
x = 17
To check.
3(17 - 7(
3(10)
30 = 30 Correct

the length and width of a room in a scale drawing is 13.5 inches by 18 inches. if the scale of 1:16, what are the actual length and width of the room in feet?
Answer:
216 & 288
Scale Width; 13.5
Scale Length; 18
Actual Lengths will be multiplied by 16 because scale is 1:16
Actual Width; 216 (13.5 x 16)
Actual Length; 288 (18 x 16)

if (x/3+1,y-2/3)is equal to (5/3,1/2) find the value of x and y
Answer:
The value of x is 2.
The value of y is [tex]\frac{7}{6}[/tex]
Step-by-step explanation:
x:
We have that:
[tex]\frac{x}{3} + 1 = \frac{5}{3}[/tex]
Multiplying everything by 3
[tex]x + 3 = 5[/tex]
[tex]x = 2[/tex]
The value of x is 2.
y:
We have that:
[tex]y - \frac{2}{3} = \frac{1}{2}[/tex]
Least common multiple between 3 and 2 is 6, which means that we multiply everything by 6.
[tex]6y - 4 = 3[/tex]
[tex]6y = 7[/tex]
[tex]y = \frac{7}{6}[/tex]
The value of y is [tex]\frac{7}{6}[/tex]
Simplify: 14ba2+21ab2−ab2.
The given expression 14ba²+21ab²−ab² can be simplified to 14ba²+20ab².
What is simplification?In arithmetic, the operation and interpretation of a function to make it simpler or easier to grasp is known as simplifying, and the process itself is known as simplification.
The expression is given in the question, as follows:
14ba²+21ab²−ab²
When you add or subtract similar terms, you can combine their coefficients. In this case, 21ab² and -ab² have the same base (ab²) and so their coefficients can be added together. 21 - 1 = 20, so 21ab² - ab² = 20ab².
Thus, the given expression can be simplified to 14ba²+20ab².

Answer:
x = 35 feet.
Step-by-step explanation:
Given that,
The height of the person is 5 feet.
The height of the flag and the eye is (x-5) feet.
We can calculate using trigonometry.
[tex]\tan\theta=\dfrac{(x-5)}{30}\\\\\tan(45)=\dfrac{(x-5)}{30}\\\\(x-5)=30\\\\x=30+5\\\\x=35\ ft[/tex]
So, the value of x is equal to 35 feet. The correct option is (c).

The domain of the graph is [-7, 7]. Note that the range of y values is also [-7, 7] since the circle is symmetric about both the x and y axes.
What is a circle?The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by:
(x - h)² + (y - k)² = r²
Where h, k is the coordinate of the center of the circle on a coordinate plane and r is the radius of the circle.
Here,
The equation of the circle shown in the graph is x² + y² = 49 representing a circle with a radius of 7 and a center at the origin (0, 0).
The domain of this graph is all the possible x values that can be on the circle. Since the circle is centered at the origin, any x value within the range [-7, 7] can be on the circle.
Therefore, the domain of the graph is [-7, 7]. Note that the range of y values is also [-7, 7] since the circle is symmetric about both the x and y axes.
