an angle measures 58.4° more than the measure of its supplementary angle what is the measure of each angle
Answer:
58.4
119.2
Step-by-step explanation:
Givens
Let one angle = x
Let the other angle = x + 58.4
Together they make 180 degrees.
Equation
x + x + 58.4 = 180 Collect like terms.
Solution
2x + 58.4 = 180 Subtract 58.4 from both sides
2x = 180 - 58.4
2x = 121.6 Divide by 2
x = 60.8
Answer
x = 60.8
x + 58.4 = 119.2
Answer:
60.8° and 119.2°Step-by-step explanation:
α - smaller angle
β = α + 58,4° - larger angle
The sum of supplementary angles is 180°.
Therefore:
α + β = 180°
α + α + 58.4° = 180°
2α = 180° - 58.4°
2α = 121.6°
α = 121.6°÷2 = 60.8°
β = 60.8° + 58.4° = 119.2°
Checking: 119.2° + 60.8° = 180°

How do you graph y=3/2x+1
Answer:
Step-by-step explanation:
The graph for the given equations is plotted in graph below.
The given equation is y=3/2 x+1.
What is the graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.
Graph the line using the slope and y-intercept, or two points.
Slope: 3/2
y-intercept: (0,1)
Plot (0, 1) and (2, 4)
Therefore, the graph for the given equations is plotted in graph below.

4−6n=60−2n
what is n?
Answer:
n = -14
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
4 - 6n = 60 - 2n
Step 2: Solve for n
Add 6n to both sides: 4 = 60 + 4nSubtract 60 on both sides: -56 = 4nDivide both sides by 4: -14 = nRewrite: n = -14Step 3: Check
Plug in n into the original equation to verify it is a solution.
Substitute in n: 4 - 6(-14) = 60 - 2(-14)Multiply: 4 + 84 = 60 + 28Add: 88 = 88Here we see that 88 does indeed equal 88.
∴ n = -14 is a solution of the equation.

Answer:
Step-by-step explanation:
y = mx + b
Take any two points and set up 2 equations with 2 unknowns.
I'll start with the first two
y = 4x + b
410 = 4x + b (1)
440 = 6x + b (2)
Subtract (1) from (2)
440 = 6x + b
410 = 4x + b Subtract
30 = 2x Divide by 2
30/2 = 2x/2
x = 15
440 = 6(x) + b
440 = 6*15 + b
440 = 90 + b
b = 350

m<4=
degrees
*question in picture*
Answer:
38 degrees, see below :)
Step-by-step explanation:
Hello! :)
So, we can use the Base Angles theorem to say the angle with 62 degrees is equal to angle 1.
Now we know angle 1 = 62 degrees.
Next, we can use the exterior angles theorem to say that angle 3 is the sum of the remote interior angles of the triangle so:
angle 3 = 62 + angle 1
= 62 + 62
= 124
Now we know angle 3 = 124 degrees
We can find angle 4 by subtracting 18 degrees and angle 3 from 180 degrees because we know that they all have to add up to 180 so:
angle 4 = 180 - (18 + 124)
= 180 - 142
= 38 degrees.
SOMEONE HALP MEEEEEEEE
Answer:
in which class r u?............
Answer:
This I am not so sure though but might be correct but what the heck xD
Step-by-step explanation:
2)
There are three points labelled
[tex]A(100,10)\ B(180,21)\ C(200,5)\\[/tex]
The points whose (x , y) values represent the group reaching its fundraising goal would be B(180,21) as its on the line which means it satisfies the equation. The other points A and B are anomalies which don't lie on the line and thus don't satisfy the equation. So 180 tickets were sold during 21 hours of rental thus reaching the fundraising goal.
3)
The graph would be a solid line that represents the situation (180,21)
If it were (200,5) the line would have been dotted and the area shaded would be under the line .
If it were (100,10) the line would have been dotted and the area shaded would be above the line
Choose the property of real numbers that justifies the equation. Look at the picture below!
Answer:
1) 4·(n + 9) = 4·n + 4·9; Distributive Property
2) (6·7)·m = 6·(7·n); Associative Property of Multiplication
3) b · 1 = b; Multiplicative Identity Property
4) a + (-a) = 0; Additive Inverse Property
Step-by-step explanation:
1) The given equation and the properties that justifies the equation are;
4·(n + 9) = 4·n + 4·9
The above equation can be written as follows;
4 × (n + 9) = 4 × n + 4 × 9
Therefore, the common factor, 4 is distributed across the to the two terms inside the parenthesis, which gives the property as distributive property
2) (6·7)·m = 6·(7·n)
The above equation gives the association of the product of the first two terms on the left multiplied by the third term being equal to the product of the first term and the association of the product of the last two terms on the right of the term on the right hand side of the equation
Therefore, we have associative property of multiplication
3) b · 1 = b
The value of the product of any variable and 1 is the value of the variable
Therefore, we have the multiplicative identity property
4) a + (-a) = 0
The sum of a variable (or number) and the negative (or opposite) of the variable (or number) is 0
Therefore, we have the additive inverse property

4m divided by 3/5; m = 3/4
Answer: 5
Step-by-step explanation:
Answer:5
Step-by-step explanation:
If m= 3/4 then plug in 3/4 to 4m, 4(3/4)=3. Then when dividing fractions you take the reciprocal of the second then multiply; so 3/1 divided 3/5 = 3/1 • 5/3=5 you can cross cancel the 3
A graduated cylinder actually contains 7.5 mm of water 1/2 measures the volume of the water inside the graduated cylinder is measurement is 7 mm which of these is the closest percent error for hand measurement
Answer:
6.667%
Step-by-step explanation:
Given that:
Actual measurement = 7.5 mm
Measured value = 7 mm
Percentage error :
Error / (Actual measurement.) * 100%
(Actual measurement - measured value)
Error = 7.5 - 7 = 0.5 mm
Percentage error = (0.5 / 7.5) * 100%
Percentage error = 0.0666666 * 100%
= 6.667%

If 5 - 2x = 21, then what is the value of 3 - x?
Answer:
11
Step-by-step explanation:
first solve 5-2x=21
subtract 5 on both sides to get
-2x=16, then divide -2 on both sides to get
x= -8 then
3-(-8) which is 3+8=11
sec 16° cosec 74° - cot 74° tan 16°
Answer:
1.
Step-by-step explanation:
sec 16° cosec 74° - cot 74° tan 16°
= 1/ cos 16 * 1/ sin 74 - 1/tan 74 * tan16
= 1/ cos16 sin 74 - cos74/ sin74 * sin 16 / cos 16
Now cos 16 = sin 74 and sin 16 = cos 74 (supplementary angles) so:
= 1 / cos^2 16 - sin 16/cos 16 * sin 16 / cos 16
=( 1 - sin ^2 16 )/ cos^2 16
= cos^2 16 / cos^2 16
= 1.
