Ramon simplified this expression correctly. Here is what he wrote 12x+2-5. 12x-3 why didn't Ramon combine the 12x with the 2 or -5
Answer:
He didn't combine the 12 with the two or the -5 because it has a variable.
Step-by-step explanation:
There is an unknown to it, like how much it is multiplied by or something. Since the 2 and the -5 didn't have a variable attached to them, they could be combined with teach other, but not the 12.

Answer:
124.80 ft
Step-by-step explanation:
Height of Daniel = 6 ft
The angle of elevation from his eyes to the top of the statue is = 68°
Daniel is 48 ft away from the base of the statue
To find the height of the statue apply the tangent of an angle formula then add height of Daniel as;
Tan 68° = h/48
h= {48 tan 68°} + 6 ft
h= 124.804168964
h= 124.80 ft

Answer:
The answer is A
Step-by-step explanation:
Use the form y = mx + b for your answer. Since 32 is the starting point, it will represent b. b represents the y intercept. Since the temperature decreases every hour, the second part of the equation would -2h. So, if you put it together, the final equation is y = -2h + 32.

The price of gas at Bob's Gas Station is $0.25 less per gallon than Phil's Gas Station. Which equation shows the price of gas at Bob's Gas Station?
A p = 2.59
OB. p = 2.79
oc. p= 2.759
OD p = 39
Answer: A
Step-by-step explanation:
The equation p = 2.5g shows the price of gas at Bob's Gas Station.
What is equation?The definition of an equation in algebra is a mathematical statement that proves two mathematical expressions are equal.
Types of Equations:
Linear Equation: More than one variable may be present in a linear equation. An equation is said to be linear if the maximum power of the variable is consistently 1.
Quadratic Equation:This equation is of second order. At least one of the variables in a quadratic equation needs to be raised to exponent 2.
Cubic Equation: A third-order equation is this one. At least one of the variables in cubic equations needs to be raised to exponent 3.
Rational Equation: A fractional equation having a variable in the numerator, denominator, or both is referred to as a rational equation.
the equation of price of gas at Phil's station is:
for p = 2.7g +0.25g
p(5) = 2.7*5+0.25*5
= 14.75 (which is not true)
hence,
p = 2.5g + 0.25*g
p(5) = 2.5*5 + 0.25*5
p(5) = 13.75
hence equation of price of gas at Bob's station is:
p = 2.5g

A museum curator needs to frame a rectangular painting. The painting is 30 inches by 17 inches. If the frame has a width of x on all sides, what is the quadratic function that models the area of the painting and frame?
Answer:
(30 + 2x) * (17 + 2x)
Step-by-step explanation:
Dimension of painting = 30 by 17 inches
Width of frame on all sides = x
Painting and frame takes the shape of a rectangle :
Area of rectangle = Length * Width
Area of painting = (30 * 17)
Area of frame ;
Length = (x + x) = 2x ;
Width = (x + x) = 2x
Area of frame = 2x * 2x
Equation for the Area of painting and frame :
(30 + 2x) * (17 + 2x)
a 100oz bottle costs $2.97 and a 200oz bottle costs $5.78 what is the unit price of each one?
Answer: BOTTLE 1 =0.0297 BOTTLE 2 =0.0289
Step-by-step explanation:
In a unit rate, the denominator is always 1. So, to find unit rate, divide the denominator with the numerator in a way that the denominator becomes 1. For example, if 50 km is covered in 5.5 hours, the unit rate will be 50 km/5.5 hours = 9.09 km/hour
bottle 1: $2.97/100 oz = unit rate
bottle 2: $5.78/200 oz=unit rate
BOTTLE 1 =0.0297
BOTTLE 2 =0.0289

The sum of two numbers is -6. The difference is 16. Find the two numbers.
Answer:
[tex]-5\:\mathrm{and}\: 11[/tex]
Step-by-step explanation:
We can write the following system of equations:
[tex]\begin{cases}x+y=6\\x-y=16\\\end{cases}[/tex]
Adding both equations together, we isolate [tex]x[/tex] and get:
[tex]2x=22,\: x=11[/tex]
Plugging [tex]x=11[/tex] in any of the equations, we can solve for [tex]y[/tex]:
[tex]11+y=6,\: y=-5[/tex]
Verify that the solution pair [tex](11, -5)[/tex] works [tex]\checkmark[/tex]
Therefore, the two numbers are [tex]\fbox{$-5\:\mathrm{and}\: 11$}[/tex].

What are the domain and range of the function?
The domain is the set of integers, and the range is y > 4.
The domain is the set of integers, and the range is y > 0.
The domain is the set of real numbers, and the range is y > 0.
The domain is the set of real numbers, and the range is y > 4.
Answer:
The answer is C, The domain is a set of real numbers, and the range is y>0.
Step-by-step explanation:
If you recall from the instruction, the domain has to be whole numbers, because of it is not then the function will decrease into fractions never quite reaching zero. X has to be a real number, because it cannot be a fraction to keep an increasing rate, making the domain all real numbers. The range can never hit 0, so that means y>0.
Based on the values of the ordered pairs in the table of the exponential function, the domain is a set of real numbers, and the range is y>0.
What are the domain and range of the function?
The domain of a function refers to the set of possible input values.
For a graph, the domain refers to the set of possible input values shown on the x-axis.
The range of a function is the set of possible output values.
For a graph, the range is the set of possible output values shown on the y-axis.
Based on the values of the ordered pairs in the table of the exponential function, the domain is a set of real numbers, and the range is y>0.

The surface areas of two cubes have a ratio of 49to 81. What is the ratio of the edge lengths of the two cubes
Answer:it is 3 to 4
Step-by-step explanation:
This is correct
The ratio of the edge lengths of the two cubes is 7 : 9.
What is surface area of cube?The surface area of the cube can be defined as the total area covered by all six faces of the cube.
Given
The surface areas of two cubes have a ratio of 49 to 81.
Formula of surface area of cube = 6[tex]a^{2}[/tex]
Surface area of cube 1 = [tex]6a^{2} _{1}[/tex]
Surface area of cube 1 = [tex]6a^{2} _{2}[/tex]
Surface areas of two cubes have a ratio of 49 to 81.
[tex]\frac{6a^{2} _{1} }{6a^{2} _{2}}=\frac{49}{81}[/tex]
⇒ [tex]\frac{a^{2} _{1} }{a^{2} _{2}}=\frac{49}{81}[/tex]
⇒ [tex](\frac{a_{1} }{a_{2} } )^{2} =\frac{49}{81}[/tex]
⇒ [tex]\frac{a_{1} }{a_{2} } =\sqrt{\frac{49}{81} }[/tex]
⇒ [tex]\frac{a_{1} }{a_{2} } =\frac{7}{9} }[/tex]
