Answer:
Well I mean There are multiple solutions I think, a = 26.25
Step-by-step explanation:
Simplifying
12a + 7c = 315
Solving
12a + 7c = 315
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-7c' to each side of the equation.
12a + 7c + -7c = 315 + -7c
Combine like terms: 7c + -7c = 0
12a + 0 = 315 + -7c
12a = 315 + -7c
Divide each side by '12'.
a = 26.25 + -0.5833333333c
Simplifying
a = 26.25 + -0.5833333333c
[tex]12a+7c=315\\\\\implies 12a = 315-7c\\\\\implies a = \dfrac{315-7c}{12}\\\\\implies a = \dfrac{7}{12}(45-c)[/tex]

The polynomial which must be added to 3x² +4x + 7 to obtain a sum of 0 is; -3x² -4x +7.
Let the polynomial which must be added to 3x² +4x + 7 to obtain a sum of 0 be represented by P.
In essence;
P + 3x² +4x + 7 = 0.By subtracting 3x² +4x + 7 from both sides of the equation to obtain the value of P; we have;
P = 0 -3x² -4x +7.Ultimately, P = -3x² -4x +7.

Solving a One-Variable Linear Equation
Answer:
[tex]\Longrightarrow:\boxed{\sf{h=14}}[/tex]
Step-by-step explanation:
Isolate the term of h from one side of the equation.
Use the distributive property.
Distributive property:
→ A(B+C)=AB+AC
7h-5(3h-8)=-72First, multiply expand.
⇒ -5(3h-8)
⇒ -5*3h=-15h
⇒ -5*8=40
Rewrite the problem.
→ -15h+40
⇒ 7h-15h+40=-72
⇒ 7h-15h=-8h
→ -8h+40=-72
Subtract by 40 from both sides.
⇒ -8h+40-40=-72-40
Solve.
⇒ -72-40=-112
⇒ -8h=-112
Then, you divide by -8 from both sides.
⇒ -8h/-8=-112/-8
Solve.
Divide the numbers from left to right.
→ -112/-8=14
[tex]\Longrightarrow: \boxed{\sf{h=14}}[/tex]
Therefore, the correct answer is h=14.I hope this helps! Let me know if you have any questions.

An astronaut drops a hammer on the Moon as part of an experiment. Before the drop, he raises the hammer by a height of 1 m, which increases its gravitational potential energy by 1.2 J. The mass of the hammer is 0.75 kg. Calculate the gravitational field strength on the Moon.
Answer:
1.6 N/kg
Step-by-step explanation:
The units of gravitational field strength are newtons per kilogram. The joule is a derived unit equivalent to a newton·meter.
Then the field strength is ...
newtons/kg = (1.2 N·m)/((1 m)(0.75 kg)) = 1.6 N/kg

Find the formula for an inverse proportion, knowing that its graph goes through the point: A(8, 0.125) PLEASE EXPLAIN WELL! THANK YOU
The formula for the given inverse proportion is:
y = 1/x
How to get the formula of the inverse proportion?
The general formula of an inverse proportion is written as:
y = k/x
Where k is the constant of proportionality.
In this case, we know that the point (8, 0.125) belongs to the graph, then replacing these values on the general formula we get:
0.125 = k/8
Solving for k we get:
0.125*8 = k = 1

This is easy....
First, the frequency is how many times a number or certain value in a set of data appears...
So basically, its asking you for the number of times that a number in between 0 and 9 appears in the data set:
23, 15, 18, 11, 30, 32, 47, 5, 9, 10, 0, 34, 39, 49, 9
To make this easier, we can put them in numerical order.
0,5,9,9,10,11,15,18,23,30,32,34,39,47,49
Now, just single out the numbers before 10.
0,5,9,9
4 numbers, so its 4. The number of times a number between 0 and 9 appears in the data set is 4. That goes in the Frequency side...

Johnson cut a round pizza into 12 equal pieces. He ate 4 adjacent pieces. What is the measure of the angle of the pizza that Johnson ate?
A.
48°
B.
90°
C.

D.
160°
Answer:
C 120 degrees
Step-by-step explanation: 3 times 4 equals 12 so if 4 peices are eaten then there is only 2/3 left so theres only 240 degrees left of the pizza so we take 360 minus 240 we get 120 so there is 120 degrees of pizza eaten by johnson.
