Answer:
7. 4
8. 7
Step-by-step explanation:
7. [tex] \frac{1}{2} = \frac{x}{8} [/tex]
Cross multiply
[tex] 1*8 = x*2 [/tex]
[tex] 8 = 2x [/tex]
[tex] \frac{8}{2} = \frac{2x}{2} [/tex] (division property of equality)
[tex] 4 = x [/tex]
[tex] x = 4 [/tex]
8. [tex] \frac{3}{x - 3} = \frac{6}{8} [/tex]
Cross multiply
[tex] 3*8 = 6(x - 3) [/tex]
[tex] 24 = 6x - 18 [/tex]
[tex] 24 + 18 = 6x [/tex] (addition property of equality)
[tex] 42 = 6x [/tex]
Divide both sides by 6
[tex] 7 = x [/tex]
[tex] x = 7 [/tex]

Answer:
5.2
Step-by-step explanation:
I took the Quiz.
If An architect is reading a plan that is drawn on a scale of 0.65 inches to 1.25 ft. If the plan says that a room is 10 feet high, then the roof is 8.13 high in the drawing.
What is fraction?A fraction represents a part of a whole or, more generally, any number of equal parts.
Based on the given conditions formulate 1.25÷10=1+x
If the fraction is defined, the denominator cannot equal 0,x≠0
Append the inequality as the domain x≠0
Multiply both sides by the common denominator:
1.25×10x/10=10x/x
Reduce the fractions: 5x/4=10
5x=40
x=8
It is approximately near to 8.13 inches.
Hence, 8.13 inches high is the roof in the drawing.

FYI 7 over 2 (negative) is -3.5 on that number line, and since you want go to a number greater than -3/2, which is -1.5, now that we know our decimals, 1., it makes this easier and 2, now we make our inequality and solve it. Here we just do -3.5<x, and if you need to do it on the number line start from -7/2 and then go to -3/2 and draw an arrow, and the circle has to be an O not a black dot because it isnt greater/less than OR equal to.

The zeros of the function f(1) = -(x + 1)(0 - 3)(x + 2) are –1, 3, and __and the y-intercept of the function is located at (0,__)
Pls help
Answers
Given:
Consider the given function is [tex]f(x)=-(x+1)(x-3)(x+2)[/tex].
To find:
The remaining zero and y-coordinate of y-intercept.
Solution:
We have,
[tex]f(x)=-(x+1)(x-3)(x+2)[/tex]
For zeros, [tex]f(x)=0[/tex].
[tex]-(x+1)(x-3)(x+2)=0[/tex]
[tex](x+1)(x-3)(x+2)=0[/tex]
[tex](x+1)=0,(x-3)=0,(x+2)=0[/tex]
[tex]x=-1,x=3,x=-2[/tex]
So, three zeros of given function are -1, 3 and -2.
Putting x=0 in the given function, we get
[tex]f(0)=-(0+1)(0-3)(0+2)[/tex]
[tex]f(0)=-(1)(-3)(2)[/tex]
[tex]f(0)=-(-6)[/tex]
[tex]f(0)=6[/tex]
So, the y-coordinate of y-intercept of the given function is 6. It means the y-intercept is at point (0,6).
Therefore, the zeros of the function [tex]f(x)=-(x+1)(x-3)(x+2)[/tex] are –1, 3, and -2 and the y-intercept of the function is located at (0,6).

URGENT!!!! The area of a rectangular floor is 80 square feet. The length of the floor is 2 feet less than the width of the floor.
What is the width of the floor?
Drag the answers into the boxes to correctly complete the statements.
The equation Response area , where w is the width of the floor in feet, can be used to solve this problem. The width of the floor is Response area feet.
Answers
Answer:
Width of the floor = 10 feet
Step-by-step explanation:
Given that:
Area of rectangular floor = 80 square feet
Width of rectangular floor = w
Length of rectangular floor = w - 2
Now,
Area = Length * Width
80 = w(w-2)
[tex]80=w^2-2w\\w^2-2w-80=0\\[/tex]
Factorizing the equation,
[tex]w^2+8w-10w-80=0\\w(w+8)-10(w+10)=0\\(w+8)(w-10)=0[/tex]
Either,
w+8 = 0
w = -8
Or,
w-10 = 0
w=10
As width cannot be negative,
width = 10 feet
Hence,
Width of the floor = 10 feet
