Which of the following equations is equivalent to ab − 8 = 3b, when solving for b .
a = 11
b = 8/2a
b = -8/3 - a
b = -8/a - 3
The equivalent equation for the given equation is b=8/(a-3).
What is an equivalent equation?Algebraic equations with equivalent solutions or roots are called equivalent equations. An analogous equation is one that is created by adding or removing the identical quantity or expression from both sides of a given equation. An equation is equivalent if both sides are multiplied or divided by the same non-zero value.
The given equation is ab-8=3b.
Now, transpose 3b to other sides of an equation, we get
ab-3b=8
b(a-3)=8
b=8/(a-3)
Therefore, the equivalent equation for the given equation is b=8/(a-3).

Answer:
16 in.
Step-by-step explanation:
Notice that 20*1.5 = 30
Use this ratio for 24 except reverse.
16*1.5 = 24
Hope this helps! Have a nice day!
Answer:
16
Step-by-step explanation:
Real length: 30 ft
Drawing length: 20 in.
Real width: 24 ft
Drawing width: x
30/20 = 24/x
3/2 = 24/x
1/2 = 8/x
x = 2 * 8
x = 16

6. When Landon saves $15 more, he will have enough money to buy a basic MP3 player. The player he wants to buy costs $199, which is 4 times the cost of the basic player. Which equation could be used to determine n, the number of dollars Landon has already saved?
A. 4n +15 = 199 B. 4(n+15) = 199 C. n + 4(15) = 199
Answer:
A) 4n+15=199
Because n is the cost of the basic player, so 4*n would be the cost of the player he wants. Also +15 since he needs 15 more dollars.

First, we must determine slope using the given points and pluging them in the slope formula*.
[tex]m = \frac{6 - (-6)}{2 - (-4)} = \frac{12}{6} = 2[/tex]
The slope is 2. You can prove this by using the graph.
Second, we plug in the slope we found, and one of the given points to solve for b using slope-intercept form**.
[tex]6 = 2(2) + b\\\\6 = 4 + b\\\\2 = b[/tex]
The y-intercept (or b) is 2. You can prove this by using the graph.
Finally, we can now create the equation of the line in slope-intercept form.
[tex]y = 2x + 3[/tex]
*Slope formula: y₂ - y₁/x₂ - x₁
**Slope-intercept form: y = mx + b
