The solution is x =
Answer:
[tex] - 30(x + 5) = 7x - 7 \\ - 30x - 150 = 7x - 7 \\ 7x + 30x = - 150 + 7 \\ 37x = - 143 \\ x = \frac{ - 143}{37} \\ x = - 3.864[/tex]

A triangle has angles described as follows: The measure of the first angle is two more than nine times a number, the measure of the second angle is five less than the first, and the measure of the third angle is 19 times the number more than the second angle. What is the measure of each angle in degrees?
Answer:
x = measure of the first angle
2x -5 = measure of the second angle
3x - 19 = measure of the third angle
the sum of the measures of a triangle is 180 degrees
x + (2x-5) + (3x-19) = 180
6x - 18 = 180
x = 33 (first angle)
2x - 5 = 2 (33) -5 = 61 (second angle)
3x - 19 = 3 (33) - 19 = 86 (third angle)
Which equation represents a line which is parallel to the x-axis?
y = x - 1
y = 8
x = - 5
x = - 3y
Answer:
y = 8
Step-by-step explanation:
The equation of a line parallel to the x- axis has equation
y = c
where c is the value of the y- coordinates the line passes through.
Then
y = 8 ← is equation of line parallel to the x- axis
Light travels at a speed of 3.00 x 10^10 cm/sec. What is the speed of light in km/hr?
Answer:
100 centimeter = 1 meter
1000 meter is 1 kilometer.
so speed is 300000 kilometer/second.
Step-by-step explanation:
There are 3600 seconds in one hour, multiply with 3600=
1080 000 000 kilometer/hour.
Answer:
1.08^9km/hr
Step-by-step explanation:
3 x 10^10cm/ 1s
(3 x 10^10 ÷100÷1000)km / 1÷60÷60
=1.08^9km/hr
which of the following to variables would you expect to have no correlation?
A-total of a ice cream sales in amount of births in a city
b-total amount of ice cream sales in amount of ice cream cones used
c-total amount of ice cream sales in temperature outside
d-total amount of ice cream sales in amount of precipitation outside
Step-by-step explanation:
A because the amount of ice cream sales doesn't relate to the number of births in a city.
B works because amount of ice cream sales can relate to money. Both C and D work because temperature could affect when people want to buy ice cream. (people most likely won't buy ice cream in the winter but most likely will in the summer)

Answer: -3
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
Given information
x= -3
Given expression
5x - 4 [7 + (2x - 4)]
Substitute x value into the expression
=5(-3) - 4 [7 + (2(-3) - 4)]
Simplify by multiplication
=-15 - 4 [7 + (-6 - 4)]
Simplify value in parentheses
=-15 - 4 [7 + (-10)]
Simplify value in bracket
=-15 - 4 [-3]
Simplify by multiplication
=-15 - (-12)
=-15 + 12

One is given the following information:
Triangle (ABC) is an isosceles triangle (meaning two of its sides are congruentSide (AB = AC)One property of an isosceles triangle is the base angles theorem. This states that in an isosceles triangle, the two angles that are opposite the congruent sides are also congruent. Applying this theorem here, one can state the following:
[tex]AB = AC\\\\m<C = m<B[/tex]
The sum of angle measures in a triangle is (180) degrees. One can apply this here by stating the following:
[tex]m<A+m<B+m<C=180[/tex]
Substitute in the proved information: express angle (<C) in terms of angle (<B).
[tex]m<A+m<B+m<C=180[/tex]
[tex]m<A+m<B+m<B=180[/tex]
Simplify, combine like terms.
[tex]m<A+m<B+m<B=180[/tex]
[tex]m<A+2(m<B)=180[/tex]
Inverse operations: solve for angle (<B)
[tex]m<A+2(m<B)=180[/tex]
[tex]2(m<B)=180-(m<A)[/tex]
[tex]m<B=\frac{180-(m<A)}{2}[/tex]
Simplify,
[tex]m<B=\frac{180-(m<A)}{2}[/tex]
[tex]m<B=90-\frac{(m<A)}{2}[/tex]
Thus, one has proven that the statement ([tex]m<B=90-\frac{(m<A)}{2}[/tex]) is true.
Please note, this proof can be typed in a statement-reason format, where the bolded part of the written words above the statement is the reason.
Find the measures of
21
and
22
80°
2102°
Answer:
Angle 1 is 22°
Angle 2 is 78°
Step-by-step explanation:
Angles on a straight line always add up to 180°.
To find Angle 2, you would have to do 180° take away 102°.
180-102=78°
Angles in a triangle also add up to 180°.
So to find Angle 1, you would have to add the two Angles you already have and take it away from 180°.
80+78=158°
180-158=22°
Hope this helps :)
f(x)=1/x; Find f(1/2)
Answer:

We can split into factors using the "guess and check" method.
Factors are in the format of:
(ax + b)(cx + d), where in this instance:
a · c = 2
bc + da = 5
b · d = 3
Thus, we get:

3= −4g −5
what is g?
Answer:
3 = - 4g - 5
3 + 5 = - 4g
8 = - 4g
8/-4 = g
-2 = g
* g = -2
The value of g in the equation 3= −4g −5 is -2.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 3=-4g-5
Three equal to minus four times of g minus five.
The g in the equation is a variable.
The operator in the given equation is Subtraction which is minus.
We need to find the value of variable g.
By addition property add 5 on both sides
3+5= −4g −5+5
The plus five and minus five will be cancelled in the right side.
3+5=-4g
Add 3 and 5 in left side.
8=-4g
By division property divide both sides by 4
g=-2
Hence, the value of g in the equation 3= −4g −5 is -2.

Kim is planning to rent a bike. It costs $15 per day plus $5 per hour. Kim's total bill was $100, how many hours did she rent the bike?
Answer:
17 hours
Step-by-step explanation:
total cost = fee + cost per hour * hours
100 = 15 + 5h
Subtract 15 from each side
100-15 = 5h
85 = 5h
Divide by 5
85/5 = 5h/5
17 =h
Answer:
Kim rent the bike for 17 hours.
Step-by-step explanation:
h=hours
15 + 5h = 100
Subtract 15 on both sides.
5h = 85
Divide 5 on both sides.
h = 17
