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).

Andre came up with the following puzzle. “I am three years younger than my brother, and I am 2 years older than my sister. My mom's age is one less than three times my brother's age. When you add all our ages, you get 87. What are our ages?”
Jada writes this equation for the sum of the ages:
(x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87
Match the meaning to each term of the equation.

x + 3
(x - 2)
3(x + 3) - 1

Answer:
x = 13
Andre is 13, Andre's brother is 16, Andre's sister is 11, Andre's mom is 47
Answer:
x = 13
Andre is 13
Brother is 16
Sister is 11
Mom is 47
All together they are 87!
Step-by-step explanation:
x + x + 3 + x - 2 + 3x + 9 - 1 = 87
6x + 9 = 87
6x = 87 - 9
6x = 78
x = 78/6

Carla makes a scale drawing of her garden that is 30 feet long and 24 feet wide. If the garden in her drawing is 20 inches long, what is its width, in inches?
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

A 24 ounce bag of dog food sells for $7.68. What is the unit rate of the dog food?
Answer:
$0.32
Step-by-step explanation:
You are going to divide 24 into $7.68 Once you get your problem set up think will 24 go into 7 no (so add a zero above the 7) but, it will not so take 24 into 76. How many times will 24 go into 76 well what is 24 x 3?? It is 72. So do that. Carry your 3 and put it above the 6. Than put your 72 under your 76 and subtract. that will get you 4 well 4 can't go into 24 so carry down your 8 and that will give you 48.Then think what will 24 go into to?? Well, 24 x 2 is 48 so thats it. Put your 2 above your 8. Subtract 48-48 and get 0. When you finish that you should have $0.32.I hope this helped. It took me 30 minutes to type that.

.525
4.21
21.4
.21
Choose the following ratios as a percent: 21 out of 40 mountain bikes

52%
Answer:
1) B is the answer
2) C is the answer
Step-by-step explanation:
1) 21:40=0.525
2) 21:40=0.525=52.5%
Because with percents it has to be out of 100 so 0.525 is not out of a hundred so multiply 0.525 times 100 to get 53.5%.

The ratio of a drawing to an object is 6 cm: 40 cm. If the length of the drawing is 36 cm, what is the actual length of the object?
Brainleast? I mean if u give me an answer and an explanation pls.
Answer:
240
Step-by-step explanation:
If the length of the drawing is 36cm, then we divide 36 by 6, which then equals 6...
Since we changed the 6, we have to change the 40...
40 x 6 = 240
so the ratio is 36:240 and the object's length equals 240cm

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

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.

4. 1 foot =_____ inches; the ratio of feet to inches is_____
5. 3 feet =_____yard; the ratio of feet to yards is_____
6. 1 yard =_____feet; the ratio of yards to feet is_____
Answer:
1)= 1 kilogram per liter (kg/l) + 8.35 pound per gallon (lb/gal)
2)= 4.4704 meters per seconds
3)= 12in= 1ft ratio is 12:1
4)= 1ft=12in ratio is 1:12
5)= 3ft= 1 yard ratio is 3:1
6)=1 yard = 3ft ratio 1:3
Step-by-step explanation:
12 in = 1 foot
1 yard = 3 feet
1 yard = 36 in

The coordinates of a point on a coordinate grid are (−1, 5). The point is reflected across the x-axis to obtain a new point. The coordinates of the reflected point are (1, −5) (−1, 5) (1, 5) (−1, −5)
Answer:
I think it should be (-1,-5)
Step-by-step explanation:
On a coordinate grid, when you flip this coordinate across the x-axis, the x-axis number won't change, meaning that -1 will stay. The intial number was in the second quadrant, this means that the new number will be in the third quadrant which is made up of all negative numbers. This means that 5 will now be graphed as negative 5, making (-1,-5) the correct answer in this situation.
