What can you do to get 2x alone on the equation? when finished, fill in the blanks and simplify the equation.
the equation is: 82.5 + 8(0.25x) = 338.5
"82.5 - ____ + 2x = 338.5 - _____
_____x = ______"
Answers
Answer:
2x = 256
Step-by-step explanation:
Your problem → 82.5 + 8(0.25x) = 338.5
82.5+8(0.25x)=338.5
⇒-256+80.25x=0
⇒2x-256=0
⇒2x=256
⇒x=256/2

Cubic bins with closed tops are used to transport melons to the farmers market. The edge length of each bin is 1. 5 m. What is the surface area of the outside of one of the bins? Drag and drop the correct answer into the box. Response area m².
Answers
Cube has all six faces as square. The surface area of the outside of one of the bins is 13.5 m².
What is the surface area of the cube?The surface area of the cube is the sum of the area of all the sides of the cube. All the six sides of the cube are made of the same size square, therefore, the surface area of the cube is 6s², where s is the length of its single side.
As it is given that the melons are kept in cubic bins whose top is closed, therefore, the cubic bin will have all six sides, with the length of the side as 1.5m.
We know the formula for the surface area of the cube, therefore, the surface area of the cubic bin is equal to the surface area of the cube with side 1.5m,
[tex]\text{Surface area of the cube} = 6s^2[/tex]
[tex]= 6(1.5)^2\\\\= 6 \times 2.25\\\\=13.5\rm\ m^2[/tex]
Hence, the surface area of the outside of one of the bins is 13.5 m².

[tex]\mathrm{7x=8x+2}[/tex]

a filing cabinet measures 5 feet high 18 inches wide and 2 feet deep. what is the volume of the filing cabinet
Answers
Answer:
Volume of the filling cabinet = 15ft^3
Step-by-step explanation:
volume = d * b * h
and the filling cabinet is
height = 5ft
width = 18 inch
depth = 2ft
we will first convert the width from inches to feet
where 1 ft -------- 12 inches
(x) ft ---------18 inches
therefore by cross multiplying
12 * (X) = 18 * 1
12 (X) = 18
X = 18 / 12
X = 1.5 ft
so Volume = 2 * 1.5 * 5 = 15 cubic feet or 15ft^3

Answer:
b - correspondinga - alternate interiord - verticalc - alternate exteriore - supplementaryb - correspondingStep-by-step explanation:
This is basically a vocabulary question. Angle pairs around a transversal crossing a pair of parallel lines all have names. Those names are used to refer to different theorems about the relationships of the angles to each other. Once you understand the words being used, the vocabulary is easier to remember.
Linear Pairs and Vertical AnglesAngles formed where one line crosses another form a linear pair if they share a side and the non-shared sides are opposite rays. If they share a vertex, but not a side, they are vertical angles. The angles of a linear pair are supplementary: they total 180°. Vertical angles are supplementary to the same angle, so vertical angles are congruent. These relations hold anywhere lines cross.
__
Angle Names at a TransversalWhere a single line crosses two (parallel) lines, that line is called a "transversal". Four angles will be formed at each intersection. Some of those angles are between the (parallel) lines, so are referred to as interior angles. The ones that are not between the (parallel) lines are referred to as exterior angles. The angles are alternate if they are on opposite sides of the transversal, and they are consecutive, or same-side if they are on the same side of the transversal.
Angles that lie in the same direction from the crossing point (to the northeast, for example) are corresponding angles.
__
In your figure, we can identify the following pairs:
corresponding: (a, f), (b, g), (c, h), (e, i)alternate exterior: (a, i), (c, g)alternate interior: (b, h), (e, f)consecutive exterior: (a, g), (c, i)consecutive interior: (b, f), (e, h)vertical: (a, e), (b, c), (f, i), (g, h)linear pairs: (a, b), (a, c), (b, e), (c, e), (f, g), (f, h), (g, i), (h, i)The theorems referenced above will tell you if and only if the lines are parallel ...
corresponding, alternate interior, alternate exterior angles are congruentconsecutive interior, consecutive exterior angles are supplementary (total 180°)____
Using the above, we find the answers to your questions to be ...
1. (a, f) - corresponding angles (b)
2. (b, h) - alternate interior angles (a)
3. (h, g) - vertical angles (d)
4. (c, g) - alternate exterior angles (c)
5. (a, c) - supplementary angles (e)
6. (e, i) - corresponding angles (b)
_____
Additional comment
In the above, we put (parallel) in parentheses, because these same definitions apply where the crossed lines may not be parallel. The relevant angle relationships can be used to determine if the lines are parallel or not. For example, if "corresponding" angles are congruent, the lines will be parallel. If "consecutive interior" angles do not total 180°, the lines cannot be parallel.
These same relationships hold in geometric figures, such as rectangles, trapezoids, parallelograms. For example, each side of a parallelogram is a transversal crossing a pair of parallel lines (the adjacent sides). Sometimes, you're asked to prove particular angle relationships in these figures. You can often do so by making use of the angle theorems related to parallel lines.

Answers
Answer:
Given:A ∆ with an exterior angle :116° & two interior angles 7x+6 & 4x
To find :The value of angle 7x+6
Solution:we know that ,
The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non adjacent interior angles of the triangle.
so,
[tex]7x + 6 + 4x= 116 \\ 11x + 6 = 116 \\ 11x = 116 - 6 \\ 11x = 110 \\ x = 110 \div 11 \\ x = 10[/tex]
so ,the measure of green angle would be
[tex]7x + 6 \\ placing \: the \: value \: of \: x \: as \: 10 \\ 7 \times 10 + 6 \\ = 70 + 6 \\ = 76[/tex]
Verification:To verify our answer ,the sum of the resultant value of green angle and 4x should be 116°(the exterior opposite angle)
so,
[tex]7x + 6 + 4x = 116 \\ 7 \times 10 + 6 + 4 \times 10 = 116 \\ 70 + 6 + 40 = 116 \\ 76 + 40= 116 \\ 116 = 116 \\ \\ hence,\: verified[/tex]
Solution:
Note that:
Green angle = 7x + 64x + 7x + 6 + (180 - 116) = 180Simplify the equation to find x.
4x + 7x + 6 + (180 - 116) = 180=> 11x + 6 + (64) = 180=> 11x + 70 = 180=> 11x = 180 - 70=> 11x = 110=> x = 110/11 = 10Substitute the value of x into the measure of the green angle.
7x + 6=> 7(10) + 6=> 76°The measure of the green angle is 76°.

Step-by-step explanation:
cuz,
x equals the number of minutes so use the y slope formula
0.10(x)+the intercept = y
0.10(350)+the intercept = 84
35+the intercept = 84
the intercept = 49
so the equation is
0.10(x)+49 = y

1/10(x)+49 = y
1/10(300)+49=y
30+49=y

a = 64b = 112c = 78d = 88==========================================
Explanation:
The 102 inscribed angle cuts off the arc that's composed of the 140 and 'a'.
Due to the inscribed angle theorem, we know that a+140 is exactly equal to twice that of 102.
This means,
a+140 = 2*102
a+140 = 204
a = 204-140
a = 64
-----------------
The angles 102 and c are inscribed angles opposite one another. They add to 180. This is true for any inscribed quadrilateral.
c+102 = 180
c = 180-102
c = 78
-----------------
Another useful rule is that the four angles of any quadrilateral always add to 360.
102+92+c+d = 360
102+92+78+d = 360
272+d = 360
d = 360-272
d = 88
-----------------
The inscribed angle d cuts off the arc a+b
This means 2d is the measure of a+b because of the inscribed angle theorem.
a+b = 2d
64+b = 2*88
64+b = 176
b = 176-64
b = 112
