find the value of "x" in the following
(a) 60° (b) 125°
Step-by-step explanation:-
a)Given are three [tex]x[/tex]'s, so,
[tex]3x = 180[/tex](As all sides of triangle add upto 180°)
[tex] = > x = \frac{180}{3} [/tex]
[tex] = > x = 60[/tex]
Hence, value of x is 60°
b)Given two interior angles(55°,70°) & one exterior angle([tex]x[/tex]°)
[tex] = > x° = (55 + 70)°[/tex]
[tex] = > x° = 125°[/tex]
Hence, value of x is 125°

A $3,000 loan is taken out for 12% interest for 6 months. What is the amount of interest charged?
A. $36.00
B. $90.00
C. $180.00
D. $270.00
Answer:
$180
Step-by-step explanation:
Simple interest → ( principal * rate of interest * time in years ) ÷ 100
Here the principal is $3,000, rate of interest is 12%, years in years will be
(6/12) = 0.5 years
Using the formula:
Interest charge → ( 3,000 * 12 * 0.5 ) ÷ 100
→ ( 18000 ) ÷ 100
→ $180

5) A farmer raises turkeys and pigs. There are 15 animals all together. The farmer
counts 34 legs on these animals. How many of each type of animal does the farmer
have? (See #7 in Notes)
t-turkey
p-Pigs
Answer:
2 pigs, 13 turkeys
Step-by-step explanation:
34=2t+4p (equation for legs)
t+p=15 (equation for total # of animals) --> t=15-p
substitution:
34=2(15-p)+4p
p=2
plug back in to other equation
t=15-(2)
t= 13

Aviva deposited some amount of money at a 4% annual interest rate into her bank account. The money was left in the account for 18 months, and she did not make any more deposits.
If Aviva's money earned $240 interest after 18 months, how much money did she deposit into the account?
Answer:
Aviva deposited $4,000
Step-by-step explanation:
Given:
$240 is the 6% interest rate annually (1.5 years)The money was left in the account for 18 monthsSolving:
We'll create an equation to find the amount of money Aviva deposited.
D = 240(50/3)
D = the amount of money she has deposited.
50/3 represents 94% of D.
Since 240 is 6% of the deposit Aviva has deposited, multiplying 50/3 by 240 will equal 100% of D.
Solve:
4,000 = 240(50/3)
The amount of money Aviva deposited is $4,000.
*This is one method to solve.

answer:
n = [tex]-\frac{3}{2}[/tex]Explanation:
→ [tex]4(n+10) = 34[/tex]
→ [tex]\frac{4(n+10)}{4} = \frac{34}{4}[/tex]
→ n + 10 = [tex]\frac{17}{2}[/tex]
→ n = [tex]\frac{17}{2} -10[/tex]
→ n = [tex]\frac{17-20}{2}[/tex]
→ n = [tex]\frac{-3}{2}[/tex]
Answer:
[tex]\sf n=\dfrac{-3}{2}[/tex]
Step-by-step explanation:
Given equation: 4(n + 10) = 34
Step 1: Expand the expression.
[tex]\sf \implies \boldsymbol{\sf 4(n + 10)} = 34[/tex]
[tex]\sf \implies \boldsymbol{\sf 4(n) + 4(10)} = 34[/tex]
[tex]\sf \implies 4n + 40 = 34[/tex]
Step 2: Subtract [tex]\sf 40[/tex] from both sides and combine like terms.
[tex]\sf \implies 4n + 40 - 40 = 34 - 40[/tex]
[tex]\sf \implies 4n = -6[/tex]
Step 3: Isolate the variable ([tex]\sf n[/tex]) (simply if necessary).
[tex]\sf \implies \dfrac{4n}{4} = \dfrac{-6}{4}[/tex]
[tex]\sf \implies n=\dfrac{-6}{4} = \dfrac{-3}{2}[/tex]

413=11−x
11 decreased by 413 is the same as a number.
413 is the same as a number decreased by 11.
413 is the same as 11 decreased by a number.
A number is the same as the difference of 11 and 413.
Answer:
option b
Step-by-step explanation:
413 is the same as a number decreased by 11 because when you say 11 is decreased by a number that means we are subtracting a number from 11 but when you say a number is decreased by 11 it means 11 is being subtracted from a certain number to give 413

video store charges $12 for used games and $25 for new games. Jonathan has saved $300 to spend on video games. This scenario is represented by a linear equation.
12x + 25y = 300
x = number of used games
y = number of new games
How many games can Jonathan buy if he spends all his money on used games?
Answer:
He can spend games at a rate of y = -0.48x + 12
Step-by-step explanation:
12x + 25y = 300
Move the 12x on the other side.
25y = -12x + 300
Divide the 25y with everything.
y = -0.48x + 12
