Answer:
$55.90
Step-by-step explanation:
First, create an equation representing her earnings each day.
Let x represent the number of hours that she walks the dog.
Since she charges $10.30 per hour, the cost from walking is 10.3x
She also charges $3.75 as a base fee, which has to be added
Putting this together, we get the equation y = 10.3x + 3.75
Plug in 5.5 as x to find her earnings:
y = 10.3x + 3.75
y = 10.3(5.5) + 3.75
y = 60.4
Since the spends $4.50 on dog treats a day, we have to subtract this from her earnings:
60.4 - 4.5
= 55.9
So, if she works for 5.5 hours, she will earn $55.90

Which fraction is BETWEEN 2/11 and 3/11?
Answer:
5/22
Step-by-step explanation:
The fraction is 5/22 between 2/11 and 3/11.
What is the fraction?A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
We have been given that (2/11) and (3/11)
To determine whether the fraction is between 2/11 and 3/11,
We need to apply the concept of the midpoint to the required fraction.
So the required fraction = (2/11 + 3/11)/2,
The required fraction = (5/11) ×1/2
The required fraction = 5/22
Hence, the fraction is 5/22 between 2/11 and 3/11.

ace's grandfather is 3 years older than Ace's grandmother. their combined age is 121 years. how old is each?
Answer: Grandfather = 62
Grandmother = 59
Step-by-step explanation:
1) Organize information.
m + 3 = ff + m = 121m + (m + 3) = 1212) Simplify.
2m + 3 = 121 -3 -3 2m = 118÷2 ÷2m = 593) Insert value of m into m + 3 = f.
59 + 3 = f59 + 3 = 624) Check work.
59 + 62 = 121?YesSolve 4b +8= 6b - 4 b= ?
Answer:
B = 6
Step-by-step explanation:
1. 4b + 8 = 6b - 4
2. Add 4 to both sides: 4b + 12 = 6b
3. Subtract 4b from both sides: 12 = 2b
4. Divide 12 by 2: b = 6
Brainliest Please.
Answer:
b = 6.
Step-by-step explanation:
4b + 8 = 6b - 4
4b - 6b = -4 - 8
-2b = -12
b = -12/-2
b = 6.

What are the solutions of the equation
-12x+26=-(1/5)-x+2+3
Answer:
Step-by-step explanation:
Expand -(1/5)-x+2+3
-(1/5)-x+2+3
Remove the parenthesis;
=1/5-x+2+3
Add the numbers; 2+3=5
=-x+5-1/5
Convert element to fraction;
=5*5-1/5
Since the denominators are equal combine the fractions;
5*5/5-1/5
5*5-1=24
Multiply the numbers;5*5=25
=25-1
Subtract the numbers:25-1=24
=24
=-x+24/5
-12x+26=-x+24/5
Subtract 26 from both sides;
-12x+26-26=-x+24/5-26
Simplify;
-12x+26-26
Add similar elements; 26-26=0
=-12x
Simplify;-x+24/5-26
Convert element to fraction;
- 26/*5/5+24/5
Since the denominators are equal , combine the fractions;
-26*5+24
Multiply the numbers; 25*5=130
=-130+24
Add/subtract the number;-130+24=-106
=-106
=-106/5
Apply the fraction rule;
=-x-106/5
-12x=-x-106/5
Add x to both sides;
-12x+x=-x-106/5+x
Simplify;
-11x+=-106/5
Divide both sides by -11
-11x/-11=-106/5/-11
Simplify ;-11x/-11
Divide ;11/11
=1
=x
simplify;-106/5/-11
Apply fraction rule; 106/5/11
106/5*11
Multiply the numbers;5*11=55
=106/55
x=106/55

Josie drank 3 4 liter of water Monday before going jogging. She drank 3 5 liter of water after her jog. How much water did Josie drink altogether? Write your answer as a mixed number.
Answer:
[tex]Total\ water\ drank = 1\frac{7}{20}\ liters[/tex]
Step-by-step explanation:
Amount of water drank before jogging = 3/4 liter
Amount of water drunk after jogging = 3/5
Total amount of water drunk = amount drank before jogging + amount drank after jogging
[tex]Total\ water\ drunk\ = \frac{3}{4} + \frac{3}{5} = \frac{15+ 12}{20} = \frac{27}{20}\\converting\ to\ a\ mixed\ number\\ \frac{27}{20}= 1\frac{7}{20}\\\therefore Total\ water\ drank = 1\frac{7}{20}\ liters[/tex]

4 x 2/3
so just by that you can already tell that 4 x 2 + 4 x 2/3 is gonna be more because the other equation is multiplyping 2/3 by 3. The other is multiplying by 4. So therefore,
4 x 2 + 4 x 2/3 (>) 3 x 2/3

Answer:
D. x = 10, m<TRS = 60
Step-by-step explanation:
1. Approach
To solve this problem, one will set up an equation to model the problem. The problem gives that the sum of two angles (m<QRT and m<TRS) equals the third angle (m<QRS). Additionally, the measure of one of the angles is given (m<QRS = 122), and the expression for the values of the other two angles are given, (m<QRT = 7x - 8), (m<TRS = 6x). One can form an equation, and solve it to find the unknown. Finally, one can then substitute the values of the unknown, into the expression to find the measure of the angle.
2. Solve for (x)
One can set up an equation based on the given information, then solve the equation.
m<QRT + m<TRS = m<QRS
Substitute,
(7x - 8) + (6x) = 122
Simplify
7x - 8 + 6x = 122
13x - 8 = 122
Inverse operations
13x - 8 = 122
+8 +8
13x = 130
/13 /13
x = 10
3. Find (m<TRS)
Now that one has the value of (x), one can substitute the value into the given expression for the (m<TRS), and solve to find the value.
m<TRS = 6x
x = 10
m<TRS = 6(10)
m<TRS = 60

40 tickets were sold for a concert, some at 75 cents and the rest at $1.25. if the total raiwed was $42, how many had the cheaper ticket
Answer:
16 had the cheaper ticket
Step-by-step explanation:
Let the number of 75cents tickets be x
Let the number of $1.25 tickets be y
Since the total tickets is 40, hence;
x+y =40 .... 1
Also if some are sold at 75 cents and the rest at $1.25 with total of $42 earned, then;
0.75x+1.25y = 42... 2
From 1
x = 40-y
Substitute into 2;
0.75(40-y)+1.25y = 42
30-0.75y+1.25y = 42
30+0.5y = 42
0.5y =42-30
0.5y = 12
y = 12/0.5
y = 24
Since x = 40-y
x = 40-24
x = 16
The number of cheaper ticket are 16
What is an example of a square root function? In (,) form
Step-by-step explanation:
The parent function of the functions of the form f(x)=√x−a+b is f(x)=√x . Note that the domain of f(x)=√x is x≥0 and the range is y≥0 . The graph of f(x)=√x−a+b can be obtained by translating the graph of f(x)=√x to a units to the right and then b units up.
