Solve the original equation 2+1/b+2=3b/b+2 by solving the proportion. The solutions are
a.-6,-1 b. -6,1 c. -1,6 d. 1,6
Answer:
b=1
Step-by-step explanation:
2b+1+2b=3b+2b
4b+1=5b(Simplify both sides of the equation)
4b+1−5b=5b−5b(Subtract 5b from both sides)
−b+1=0
−b+1−1=0−1(Subtract 1 from both sides)
−b=−1
−b
−1
=
−1

Can you solve this geometry problem?
Answer:
m<UTV = 100°
Step-by-step explanation:
360 = 140 + 120 + m
360 = 260 + m
360 - 260 = 260 - 260 + m
100 = m
----------------------------------------
360 = 140 + 120 + 100
360 = 260 + 100
360 = 360

Allie goes cruising on her dirt bike. She rides 2 km north, 4 km west, 13 km south, 10 km east, 1 km south and 6 km east. What was her displacement?
Answer:
16.97km
Step-by-step explanation:
To get the displacement, we will use the pythagoras theorem
Sum of distances along the horizontal (east and west) is expressed as
dx = 10 - 4 + 6
dx = 6+6
dx = 12km
Sum of distances along the y;
dy = 2 - 13 - 1
dy = -11-1
dy = -12km
Find the displacement using the pythagoras theorem
D = √(12)²+(-12)²
D = √144+144
D = √288
D = 16.97km
Hence her displacement is 16.97km

Describe how you know whether an equation will be true for all values of x or true for no values of x.
Answer:
Substitute your answer for the variable x. If the equation looks accurate or is correct, then the value of x is the right answer. Not sure if this makes sense
Determining whether an equation is true for all values of x or true for no values of x requires simplifying the equation, determining its domain, checking for variable restrictions, and evaluating the equation for different values of x.
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Simplify the equation as much as possible using algebraic manipulations such as combining like terms, factoring, and expanding.
Evaluate the equation for a few different values of x to see if it holds true. If the equation is true for all values of x within the domain, then it will be true for all values of x. If there are any values of x within the domain that make the equation false, then it will be false for no values of x.
If the equation cannot be simplified or the domain cannot be determined, then it may require further analysis, such as graphing or using calculus techniques to determine its behavior.
Thus, determining whether an equation is true for all values of x or true for no values of x requires simplifying the equation, determining its domain, checking for variable restrictions, and evaluating the equation for different values of x.

Mr. Frankel bought 7 tickets to a puppet show and spent $43. He bought a combination of child tickets for $4
each and adult tickets for $9 each. Which system of equations below will determine the number of adult
tickets, a, and the number of child tickets, c, he bought?
1. a=C-9
9a + 40 =43
2. 9a +4c=43
a+c=7
3. 40 + 40 = 50
a+c=7
4. a+c= 301
a+c=7
Answer:
Step-by-step explanation:
2. 9a +4c=43
a+c=7
The total tickets for adults and children = 7 (a+c =7) 7 people in all
price for adult = $9 (9a) Price per child =$4 (4c)
total price =$ 43
9a +7c = 43

Answer:
The missing side of the triangle is 15
Please help with explanation
Answer:
B
Step-by-step explanation:
The formula for a area of the first semi circle is
[tex] \frac{1}{2} \times \pi {r}^{2} [/tex]
where r is the radius
Since 4 is the diameter, 2 is the radius
plug it in
[tex] \frac{1}{2} \times \pi {2}^{2} [/tex]
[tex] \frac{1}{2} \times 4\pi[/tex]
[tex]2\pi[/tex]
so the area of the first circle is 2
[tex]2\pi[/tex]
now let find the second circle
Since the semi circle is twice the area of AB the diameter is 8 so the radius is 4.
Put it in the equation.
[tex] \frac{1}{2} \times \pi {4}^{2} [/tex]
[tex] \frac{1}{2} \times \pi \times 16[/tex]
[tex]8\pi[/tex]
Now let find the third circle
Since it is twice the size of the second circle, the diameter is 16 and the radius is 8.
[tex] \frac{1}{2} \times \pi {8}^{2} [/tex]
[tex] \frac{1}{2} \times 64\pi[/tex]
[tex]32\pi[/tex]
Now let add the area of the semi circle
[tex]32\pi + 2\pi + 8\pi = 42\pi[/tex]
9. There are 45 marbles in a bag (black and white only). The ratio of white marbles to black marbles is 2:3.
How many of each are there?
18 white and 27 black
Step-by-step explanation:
add 2 + 3 to get 5
45 ÷ 5 = 9
since white is 2, multiply 9 by 2 to get 18
since black 3, multiply 9 by 3 to get 27

Suppose the ratio of Lev's age to Mina's age is $1 : 2$ and the ratio of Mina's age to Naomi's age is $3 : 4$. What is the ratio of Lev's age to Naomi's age? Give your answer in simplest form.
Answer:
3:8
Step-by-step explanation:
The ratio of Mina's age to Naomi's age is 3 : 4
Multiplying the above ratio by 2 = 6:8
The ratio of Lev's age to Mina's age is 1 : 2
Multiplying the above ratio by 3
= 3:6
Therefore, ratio of Lev's age to Naomi's age in simplest form.
= 3:8
Answer:
3:8
Step-by-step explanation:
Let L, M, and N stand for the three ages.
The given ratios tell us that
M = 2L
and
N = 4/3M.
Therefore,
N = 4/3 x 2L = 8/3L.
This means that Lev's and Naomi's ages are in the ratio 3:8.
After his alarm rings, Clarence has
25 minutes to get ready. He snoozes in
bed for one minute after the alarm rings
the first day, two minutes the second
day, three minutes the third day, etc.
When Clarence is down to 11 minutes to
get ready, how many days has it been?
Answer: 14 days
Step-by-step explanation:
Day 1: 1 minute snooze = 24 minutes
Day 2: 2 minute nooze = 23 minutes ; these examples show snooze time = days.
We can set up an equation for this situation: 25 - s = r ; where s = snooze time and r = time to get ready.
Given the problem, we can fill out this equation with: 25 - s = 11
When you solve this equation, time snoozed = 14.
We already know that snooze time = days, so days = 14.
