Answer:
[/tex]
Step-by-step explanation:
Solving the equation mean finding the value of x
Equation given is:
Now what we need to do is take the values with x in it to the left side of the equation and the other numbers to the right side of the equation.
Now simplify values with x and the numbers.
[/tex]
Therefore [/tex]
x =
simplify the left side by collecting like terms
7x + 1 = x + 4 ( subtract x from both sides )
6x + 1 = 4 ( subtract 1 from both sides )
6x = 3 ( divide both sides by 6 )
x = =
Answer:
SAS
Step-by-step explanation:
SAS is the correct answer
b) the acute angle AOB.
Answer:
a) 24 [cm]; b) 30°.
Step-by-step explanation:
a) the length of full the circle is: min_arc(AB)+maj_arc(AB)=π(22+2)=24π [cm]. Then the radius is: r=L/π; ⇒ r=24π/π=24 [cm];
b) if the full circle is 360° (L=24π), then m(∠AOB):2=360°:24 and the required measure of the acute angle AOB is:
m(∠AOB)=360*(1/12)=30°.

Answer:
Suppose that the height (in centimeters) of a candle is a linear function of
the amount of time (in hours) it has been burning.
After 11 hours of burning, a candle has a height of 23.4 centimeters.
After 30 hours of burning, its height is 12 centimeters.
What is the height of the candle after 13 hours?
:
Assign the given values as follows:
x1 = 11; y1 = 23.4
x2 = 30; y2 = 12
:
Find the slope using: m = %28y2-y1%29%2F%28x2-x1%29
m = %2812-23.4%29%2F%2830-11%29 = %28-11.4%29%2F19
:
Find the equation using the point/slope formula: y - y1 = m(x - x1)
y - 23.4 = -11.4%2F19(x - 11)
y - 23.4 = -11.4%2F19x + 125.4%2F19
y = -11.4%2F19x + 125.4%2F19 + 23.4
y = -11.4%2F19x + 125.4%2F19 + 23.4
y = -11.4%2F19x + 125.4%2F19 + 444.6%2F19
y = -11.4%2F19x + 570%2F19
y = -11.4%2F19x + 30, is the equation
:
What is the height of the candle after 13 hours?
x = 13
y = -11.4%2F19(13) + 30
y = -148.2%2F19 + 30
y = -7.8 + 30
y = 22.2 cm after 13 hrs
Based on the available information, and options in the question, the total change in the gift card balance after 3 weeks is option A. -$17.61
Evaluation in Mathematics is a method that is used to find the value of the expression when the variable is replaced by a given number.
In this case, to find the total change in the gift card balance after 3 weeks, calculate the total amount spent on gourmet coffee during this period.
Given that Sonia purchases a $5.87 gourmet coffee each week the total amount spent on coffee after 3 weeks can be calculated as follows:
Total amount spent = cost per coffee * number of weeks
= $5.87 * 3
= $17.61
Therefore, Sonia will have spent a total of $17.61 on gourmet coffee after 3 weeks, which will be $-17.61 of the top change in the gift card.
Hence, in this case, it is concluded that the correct answer is option A. -$17.61

Answer:
Step-by-step explanation:
find x from the given triangle.
first step is to get x
add all inside angles = 180
∠2 + ∠3 + ∠4 = 180
x + 40 + 5x + 14 = 180
x + 5x = 180 - 40 - 14
6x = 126
x = 126 / 6
x = 21
substitute x=21 into angle 4
∠4 = 5x + 14
∠4 = 5(21) + 14
∠4 = 119
lastly, add ∠1 + ∠4 = 180
∠1 + 119 = 180
∠1 = 180 - 119
∠1 = 61°
therefore, the answer is D. 61
