Answer:
B
Step-by-step explanation:
We can subtract the fixed 12 of 40 to see how much she can spend on messages alone. So we are left with $28.
At 10 cents apiece for every dollar she can send 10. So we would get 280 messages.
I dont understand the options given, I think there are equation signs missing
So it would be B I assume since x=280

( -5, ∞)
Step-by-step explanation:
6 - 11x < 61
Subtract 6 from both sides
-11x < 55
Divided both side by -11. When divided by a negative number the < switch to >
So, the answer is
x > -5

PQR is a non-right-angled triangle. QR is 5.1cm, RP is 7.8cm and PQ is 6.2cm. Find the area of PQR
Using Heron's formula the area of the triangle is 15.78cm²
What is Heron's FormulaHeron's formula is a formula for calculating the area of a triangle when the lengths of all three sides are known. It is named after the Greek mathematician and engineer Heron of Alexandria (c. 10–70 AD). The formula is:
Area = √s(s-a)(s-b)(s-c)
Where a, b, and c are the lengths of the sides of the triangle, and s is the semi-perimeter, or half the perimeter, of the triangle, given by:
s = (a + b + c)/2
Let's define the variables as;
a = 5.1b = 7.8c = 6.2s = (5.1 + 7.8 + 6.2) / 2
s = 9.55cm
The area can be calculated as;
A = √s(s - a)(s - b)(s - c)
A = √9.55(9.55 - 5.1)(9.55 - 7.8)(9.55 - 6.2)
A = 15.78cm²

Answer:
55
Step-by-step explanation:
So lets take our 50 dollars.
Next, take your increase of 5%. Remember, 5% is 0.05, and it is a increase of 5%, so we are multipling 50 by 1.05.
Before we start multiplying, lets recall that this occurs twice(2 years), but this doesnt mean we multiply 50 by 1.10. No, we just mutiply 50 by 1.05 2 times:
50*1.05
=
52.5
52.5*1.05
=
55.25
So your answer is 55 dollars(rounding down).
Hope this helps!

Part A: Maci made $170 grooming dogs one day with her mobile dog grooming business. She charges $60 per appointment and earned $50 in tips. Write an equation to represent this situation. (4 points)
Part B: Logan made a profit of $210. 00 as a mobile groomer. He charged $75. 00 per appointment and received $35. 00 in tips, but also had to pay a rental fee for the truck at $10. 00 per appointment. Write an equation to represent this situation. (4 points)
Part C: Explain how the equations from Part A and Part B differ. (2 points)
The equations for parts A and B are 170 = 60x + 50 and 210 = 75x + 35 - 10x, respectively.
What is an equation ?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
We have LHS = RHS (left hand side = right hand side) in every mathematical equation.
To determine the value of an unknown variable that represents an unknown quantity, equations can be solved.
The statement is not an equation if there is no "equal to" sign in it.
According to our question-
A) It is stated that Maci once earned $170 by grooming dogs.
For each appointment, she charges $60, and she received $50 in tips. Consequently, the equation to illustrate this is;
170 = 60x + 50
the number of appointments is x.
B) Logan earned $210.00 in profit. He charged $75.00 for each session and got $35.00 in gratuities. In addition, he had a $10.00 truck rental fee per appointment. In order to represent this, the equation is;
210 = 75x + 35 - 10x
the number of appointments is x.
C) The quantity of tips they will receive even without an appointment varies between the formulae.

A linear system has no solution if both lines are parallel.It is when the lines have same slope but different y-intercepts.Review the options1. Option A.
If you double the first equation, then it will be exact copy of the second one. It means the lines overlap, and there are infinitely many solutions.
No2. Option B
Both the x and y have same coefficients, it means the slopes are same. The y-intercepts are different, so the lines are parallel and no solution.
Yes3. Option C
Multiply one of the equations by -1 to get exact same of the other equation. Same as option A, infinitely many solutions.

NoIf the total daily wages of 7 women or 5 men is $525.What will be the daily wage of 13 and 7 women and men respectively?
Answer:
Daily wages of 13 woman = $975
Daily wages of 7 man = $735
Step-by-step explanation:
Given:
Daily wages of 7 women or 5 men = $525
Find:
Daily wage of 13 women and 7 men
Computation:
Daily wages of 1 woman = 525 / 7
Daily wages of 1 woman = $75
Daily wages of 1 man = 525 / 5
Daily wages of 1 man = $105
Daily wages of 13 woman = 13 x Daily wages of 1 woman
Daily wages of 13 woman = 13 x 75
Daily wages of 13 woman = $975
Daily wages of 7 man = 7 x Daily wages of 1 man
Daily wages of 7 man = 7 x 105
Daily wages of 7 man = $735
The temperature in knowlton is 2.5 C colder than the terminal elmwood. Which equation shows the temperature, in C, in knowlton? 9 - 2.5 = 6.5 or 9 + 2.5 = 11.5 or -9 - 2.5 = - 11.5 or -9 + 2.5 = -6.5
The equation representing the asked situation is (9 - 2.5) = 6.5
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, The temperature in Knowlton is 2.5 C colder than the terminal Elmwood.
We know, that, if temperature is colder in any area A than another area B then, A will have less temperature than B.
Therefore, temperature in Knowlton is less than that of in Elmwood.
Therefore, if the temperature in Elmwood is 9 the temperature in Knowlton will be 9-2.5 = 6.5
Hence, the required equation is 9-2.5 = 6.5

Mrs Lim has sponsored a total of 105 hot dogs and 126 cans of fruit juice for the refreshment of a classic picnic. Each student will receive the same amount of refreshment.
a) what is the greatest number of students who will get the refreshment ?
b) how many hot dogs will each student get?
C) how many fruit juices wil each student get
a) The greatest number of students who will get the refreshment is 210.
b) Each student will get 0.5 hot dogs.
c) Each student will get 0.6 cans of fruit juice.
a) To find the greatest number of students who will get the refreshment , we need to find the least common multiple of hot dogs and fruit juice.
The least common multiple is 210, which is the multiple of 105, and 126 is the least.
So the greatest number of students who will get the refreshment is 210.
b) To find the number of hot dogs each student will receive, we need to divide the total number of hot dogs (105) by the greatest number of students who will get the refreshment (210)
105/210 = 0.5
So each student will get 0.5 hot dogs.
c) To find the number of fruit juices each student will receive, we need to divide the total number of fruit juice (126) by the greatest number of students who will get the refreshment (210)
126/210 = 0.6
So each student will get 0.6 cans of fruit juice.
