3(2x - 7) = 5(x + 3) + 2x7
Answers
Answer:
x = -1.52016
Step-by-step explanation:
Step 1: Write equation
3(2x - 7) = 5(x + 3) + 2x⁷
Step 2: Solve for x
Distribute: 6x - 21 = 5x + 15 + 2x⁷Subtract 6x on both sides: -21 = -x + 15 + 2x⁷Add 21 to both sides: 0 = -x + 36 + 2x⁷Rearrange: 0 = 2x⁷ - x + 36Find roots by graphing: x = -1.52016

Find the value of c. 16 = 4 - 3c
Answers
Answer:
c = -4
Step-by-step explanation:
16 = 4 - 3c
subtract 4 from each side
16-4 = 4-4 - 3c
12 = -3c
Divide each side by -3
12/-3 = -3c/-3
-4 =c
16= 4- 3(-4)
16= 4 + 12
16=16
On-the-Go Phone Company has two monthly plans for their customers. The EZ Pay Plan costs $0.15 per minute. The 40 to Go Plan costs $40 per month plus $0.05 per minute. Which plan should you choose if you want only 200 minutes per month? Why? Justify your answer.
Answers
Answer:
The EZ Pay Plan because it would cost less than the 40 to Go Plan.
Step-by-step explanation:
You will have to calculate the amount that you would pay with each monthly plan if you have 200 minutes per month.
-EZ Pay Plan:
$0.15*200=$30
-40 to Go Plan:
$40+($0.05*200)=$40+$10=$50
According to this, the answer is that if you only want 200 minutes per month, you should choose the EZ Pay Plan because it would cost $30 which is less than the 40 to Go Plan that would cost $50.

Solve by completing the square:
x^2 + 2x - 3 =0
a. - 3 or 1
b. X-3 or -1
C. - 3 or -1
d. 2-3 or 1
Please select the best answer from the choices provided
Answers
Answer:
a
Step-by-step explanation:
Given
x² + 2x - 3 = 0 ( add 3 to both sides )
x² + 2x = 3
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(1)x + 1 = 3 + 1
(x + 1)² = 4 ( take the square root of both sides )
x + 1 = ± [tex]\sqrt{4}[/tex] = ± 2 ( subtract 1 from both sides )
x = - 1 ± 2
Thus
x = - 1 - 2 = - 3
x = - 1 + 2 = 1

Find the area. Simplify your answer.
Answers
Answer: 1.5x²
Step-by-step explanation:
Rule: To find the area of a triangle, multiply the base times one side, then divide the product by 2.
Step 1: Find the length of the left side using the pythagorean theorem.
a^2 + b^2 = c^2.
x^2 + 2x^2 = 3x^2
√3x² = 3x
Step 2: Multiply the base times the hypotenuse.
x * 3x = 3x²
Step 3: Divide by two
3x²/2 = 1.5x²

Jason has $90 to spend. He wants to purchase a bag for $35,one eraser for $10, and three pencils. Each of the pencils costs the same price. This will use up all of Jason's money. Determine the price of a pencil.
Answers
Answer:
1 pencil = $15
Step-by-step explanation:
Starting money = 90
Bag price = 35
Eraser price = 10
Price per 1 pencil = X
90 - 35 = 55
$55 after buying the bag.
55 - 10 = 45
$45 after buying the eraser.
45 ÷ 3 = 15
$15 dollars for each pencil.

if m2 = 125, m12= 37 and m18 = 102, find the measure of each angle
Answers
Answer/Step-by-step explanation:
Given:
m<2 = 125°
m<12 = 37°
m<18 = 102°
a. m<1 + m<2 = 180° (linear pair)
m<1 + 125° = 180° (substitution)
m<1 = 180° - 125°
m<1 = 55°
b. m<3 = m<18 (alternate exterior angles)
m<3 = 102° (substitution)
c. m<4 + m<3 = 180° (linear pair)
m<4 + 102° = 180° (substitution)
m<4 = 180° - 102°
m<4 = 78°
d. m<5 = m<2 (vertical angles)
m<5 = 125° (substitution)
e. m<6 = m<1 (vertical angles)
m<6 = 55° (substitution)
f. m<7 = m<12 (alternate angles)
m<7 = 37° (substitution)
g. m<8 + m<12 + m<13 = 180° (sum of triangle)
m<12 = 37° (given)
m<13 = m<18 = 102° (vertical angles)
m<8 + 37° + 102° = 180° (substitution)
m<8 + 139° = 180°
m<8 = 180° - 139°
m<8 = 41°
h. m<9 = m<18 (corresponding angles)
m<19 = 102° (substitution)
i. m<10 = m<6 (alternate interior angles)
m<10 = 55°
j. m<11 + m<6 + m<7 = 180° (sum of triangle)
m<11 + 55° + 37° = 180° (substitution)
m<11 + 92° = 180°
m<11 = 180° - 92°
m<11 = 88°
k. m<13 = m<18 (vertical angles)
m<13 = 102°
l. m<14 = m<4 (corresponding angles)
m<14 = 78°
m. m<15 = m<5 (corresponding angles)
m<15 = 125°
n. m<16 = m<6 (corresponding angles)
m<16 = 55°
o. m<17 = m<14 (vertical angles)
m<17 = 78°

En la casa de Juan, van a pedir pizza para la comida, pero cuando la van a pedir se dan cuenta que deben pedirla por perímetro o área de la misma. La mamá dice que es más grande la de perímetro de 100cm y el papá dice que es más la de área de 100cm². ¿Cuál tiene la razón? *
Answers
Responder:
La pizza con un perímetro de 100 cm es más grande ¿verdad?
Explicación paso a paso:
Deja que la pizza tenga forma circular.
Sea el área de la pizza = πd² / 4 y;
Perímetro de la pizza = πd
d es el diámetro de la pizza
Si la madre dice que el que tiene un perímetro de 100 cm es más grande, para estar seguros necesitamos obtener el diámetro de la pizza. La de mayor diámetro será la pizza más grande.
P = 100cm
100 = πd
d = 100 / π
d = 100 / 3,14
d = 31,85 cm
El diámetro de la pizza mamá es de 31,85 cm.
Si el padre dice que el que tiene un área de 100 cm² es más grande, obtengamos también el diámetro para estar seguros.
A = πd² / 4
100 = πd² / 4
400 = πd²
d² = 400 / π
d² = 400 / 3,14
d² = 127,39
d = √127,39
d = 11,29 cm
Por lo tanto, el diámetro de la pizza padre es de 11,29 cm.
Dado que el diámetro de la pizza madre es mayor que el de esa, la pizza con un perímetro de 100 cm es más grande, lo que demuestra que la madre tiene razón.

Question 1: >
Question 2: >
Question 3: <
Step-by-step explanation:
Lets start with [tex]\sqrt{83} - 12[/tex]. First you need to find the square root of 83, which is 9.1104. Right after you get the square root of 83 you need to subtract 12 which will give you -2.8895. For the second part of question one (in the image you provided), we will be doing [tex]\sqrt{49} - 10[/tex]. We will start by finding the square root of 49, which is very simple. It's 7. You would then subtract 10 from 7 which gives you -3. And finally for question 1, you have to compare -2.8895 and -3 and determine which number is greater. Which is -2.8895, so you would put >.For the 2nd question, we will start with [tex]2 + \sqrt{7}[/tex]. First, let's get the square root of 7, which is 2.6457. Now we simply add 2! You should now end up with 4.6457. Now for [tex]\sqrt{17} -1[/tex], you need to get the square root of 17, which is 4.1231. Now just simply subtract 1. You should end up with 3.1231. Now just find which number is greater. Which is 4.6457. You should put > as your answer.For the final question, we will start with [tex]15-\sqrt{15}[/tex]. Just start by getting the square root of 15, which is 3.8729. Then simply subtract 15! You should have -11.1270 as your answer. And for [tex]\sqrt{10} + 4[/tex]. Just get the square root of 10 to start which will be 3.1622. Now finally, add 4! You should get 7.1622 as your answer. Now for the final step, find the greatest number, which is 7.1622, you would then answer < for your final questionIf you have any questions just ask them below. Thank you!
