Solve for p in the literal equation 2p + 38 = 9.
p =
Answer:
p = -29/2
Step-by-step explanation:
2p + 38 = 9
Subtract 38 from each side
2p + 38-38 = 9-38
2p = -29
divide by 2
2p/2 = -29/2
p = -29/2
Answer:
p=-14.5
Step-by-step explanation:
2p + 38 = 9
-38 -38
2p = -29

14. If I share 123 sweets equally among amongst 7 children, how many sweets will each child get?
……………………………………..
Answer:
No. of sweets = 123
No. of children = 7
then
sweets per children =123/7 =17. 57
Answer: =17.57
Step-by-step explanation:
Divide the no. of sweets by the no. of children
=123/7
=17.57
Use the elimination method to solve the system of equations. Choose the correct ordered pair
Answer:
Answer is B
Step-by-step explanation:
[tex]12x - y = 25 \\ 9x + y = 17 \\ x = \frac{17 - y}{9} \\ 12( \frac{17 - y}{9} ) - y = 25 \\ [/tex]
[tex]\frac{204}{9} - \frac{12}{9} y - y = 25 \\ \frac{204}{9} - \frac{21y}{9} = 25 \\ - \frac{21y}{9} = 25 - \frac{204}{9} \\ - \frac{21y}{9} = 2.33 \\ - 21y = 20.997 \\ y = - 0.99[/tex]
[tex]y = - 1 \\ x = \frac{17 - y}{9} \\ x = \frac{17 - - 1}{9} = \frac{18}{9} \\ x = 2[/tex]
Which function is graphed below?
Answer:
[tex]g(x)=\sqrt{x+2}[/tex]
Step-by-step explanation:
Parent function of the given graph is,
f(x) = [tex]\sqrt{x}[/tex]
If the parent function is shifted 2 units to he left the new function or image function will be,
g(x) = [tex]\sqrt{x+2}[/tex]
Therefore, graph will represent the graph of the function g(x) = [tex]\sqrt{x+2}[/tex].

Answer:
21
Step-by-step explanation:
If lines m and n are equal, line t intersects both of them at the exact same angle. This means that 6x+3=7x-19. Start moving the variables to one side. 3=x-19. Then move the numbers to the other side of the equation. x=21.

Answer:
Rhombus
Energy used
Step-by-step explanation:
A rhombus is formed fromm the intersection, since the stick have equal length, Hence, all the sides will be equal and the opposite side will be parallel.
If a person exercises more and more, more energy is utilized, the dependemt variable here is the amount of energy utilized because it is the measured variable whose value is based on the amount or level of exercise the body is subjected to. The amount of exercise is the dependent variable as it gives influences the amount of energy expended

Answer: x = 8,-2
Step-by-step explanation:
x^2-6x-16=0
x =[ -(-6)+-sqrt(-6)^2 - 4x1x(-16)/2x1
x = [6+-sqrt 36+64]/2
x = 6+-sqrt 100/2
x = 6 +-10/2
x = 6+10/2, 6-10,2
x = 8, -2
Answer:
Step-by-step explanation:
This is the quadratic equation formula for the roots.
x^2 - 6x - 16 = 0
x = [- (-6) +/- √( (-6)^2 - 4*1*-16) / 2*1
x = (6 +/- √(36 + 64) / 2
x = (6 +/- √(100) / 2
x = (6 +/- 10) / 2
x = 16/2 = 8
x = -4/2 = -2

ABCF AND EFGH ARE CONGRUENT PARALLELGRAMS. AD = 10cm, MC = 8cm, and the area of ABCD is 112cm^2. What is the number of centimeters in EN? Express your answer as a decimal to the nearest tenth
The image to the question is attached below.
Answer: The value of EN is 11.2 cm
Step-by-step explanation:
We are given:
The parallelograms ABCD and EFGH are congruent, which simply means
AB = EF
BC = FG
CD = GH and
AD = EH
Area of ABCD = area of EFGH
Also, opposite sides of a parallelogram are equal. Thus,
AB = EF = CD = GH
BC = FG = AD = EH
It is given:
[tex]AD=10cm=FG\\\\\text{Area of ABCD}=112cm^2=\text{Area of EFGH}[/tex]
To calculate the area of a parallelogram, we use the equation:
[tex]Area=b\times h[/tex]
where, for parallelogram EFGH
b = base = FG = 10 cm
h = height = EN = ?
Area = [tex]112cm^2[/tex]
Plugging values in above equation, we get:
[tex]112cm^2=10cm\times EN\\\\EN=\frac{112cm^2}{10cm}=11.2cm[/tex]
Hence, the value of EN is 11.2 cm

Answer:
a=2
b=10.5
c=4
d=17.5
Step-by-step explanation:
so 3.5 miles per hour and the columns are miles and then hours
so an equation can be 3.5 (mi/hr) * t (time) = distance
so for a): 3.5*t=7
t=2
b) 3.5*3=distance
distance is 10.5
c) 3.5*t=14
t=4
d) 3.5*5=d
d= 17.5

Sam works as a baggage carrier at an airport facility. He owes a certain amount of money, in dollars, to his friend Daniel. The function y = 12x − 40 represents the amount of money that Sam has after paying Daniel back in terms of the number of hours he works at the airport.
Answer:40: the amount in dollars that sam owes Daniel. 12: the amount in dollars that sam earns per hour, y variable: the amount in dollars that sam has after paying back Daniel, x variable: the number of hours Sam works at the airport.
Step-by-step explanation:
Answer:
x variable = represents the number of hours Sam works at the airport
y variable = represents the amount in dollars that Sam has after paying Daniel
12 = is the amount in dollars that Sam earns per hour
40 = is the amount in dollars Sam owes Daniel

Four rays come together at a single point. What is the value of the missing angle?
Answer:
? = 140
Step-by-step explanation:
The rays form a circle, which is 360 degrees
90+ 105+25+? = 360
Combine like terms
220+? = 360
? = 360-220
? = 140

The pair of triangles below have two corresponding parts marked as congruent. What additional information is
needed for a HL congruence correspondence?
A. ∠M≅∠H
B. LM≅JK
C. LM≅JH
D. LN≅JK
(there is a line above the letters besides a)
Answer:
C. LM ≅ JH
Step-by-step explanation:
The criteria that needs to be satisfied before two right triangles can be said to be congruent to each other is by the Hypotenuse-Leg Theorem are:
1. Both must have a corresponding leg that are congruent to each other.
In the diagram given above, NM is congruent to KH. They are corresponding legs that are congruent.
2. The hypotenuse of one triangle must be equal to that of the other.
We are not given if the hypotenuse of one, LM is congruent to the hypotenuse of the other, JH.
Therefore, the additional information required would be:
LM ≅ JH
