First you need to pick a number for y. Lets say you pick 0
Then you need to +3 to each side
Then you can say 3=x+2 or -3=x+2.
To find x you need to subtract 2.
You answer would be (1,3) and (-5.-3)
Answer:
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the total amount owed
P is the amount of money borrowed
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
Answer:
105
Step-by-step explanation:
55+50+x=180
x=75 this is the other inside angle. to find b, you need to take 75 and subtract it from 180. this is because a straight line is equal to 180 degrees
Answer: 164 students passed and 41 students failed.
Step-by-step explanation:
Let the number of students be x
x students failed, but 4 times the failed students passed.
So 4x students passed and x students failed.
4x + x = 205
5x = 205
x = 205/5
x = 41
41 times 4 is 164 and 41 times 1 is 41.
So 164 students passed and 41 students failed
Answer:
1. 2x + 3y =22
y=4
C. (5,4)
2. y=0
-5x - 2y = -15
B. (3,0)
Step-by-step explanation:
2x+(3)(4)=22
Step 1: Simplify both sides of the equation.
2x+12=22
Step 2: Subtract 12 from both sides.
2x+12−12=22−12
2x=10
Step 3: Divide both sides by 2.
2x/2 = 10/2
x=5
====================================================================
−5x−(2)(0)=−15
Step 1: Simplify both sides of the equation.
−5x−(2)(0)=−15
−5x+0=−15
(−5x)+(0)=−15(Combine Like Terms)
−5x=−15
−5x=−15
Step 2: Divide both sides by -5.
−5x/−5 = −15/−5
x=3
