Answer:
$1054
Step-by-step explanation:
simple interest = 4% of original amount each time
850/100 = 8.5 = 1%
8.5 x 4 = 34 = 4%
34 x 6 = 204
$850 + $204 = $1054
Answer:
9+9=18
Step-by-step explanation:
as they are positive numbers so by adding it we get 18
5x+4y=-2
3x+4y=10
Make one with negative coefficient to find first what is x then solve for y .
-1(5x+4y)= -1 (-2)
3x+4y=10
-5x-4y=2
+ 3x+4y=10
_________
-x = 12
Divide both sides by -2
-2x/-2=12/-2
X= -6
Now substitute your x into one of the equations to find y .
-5x-4y=2
-5(-6)+4y=2
30+4y=2
Subtract 30 both sides
-4y= 2-30
Divide both sides by -4
Y= -28/-4
Y= 7
Your answer is in point form (-6,7) meaning x is -6 and y is 7.
Answer:
b= 29/11
Step-by-step explanation:
2b+8−5b+3=−13+8b−5
Step 1: Simplify both sides of the equation.
2b+8−5b+3=−13+8b−5
2b+8+−5b+3=−13+8b+−5
(2b+−5b)+(8+3)=(8b)+(−13+−5)(Combine Like Terms)
−3b+11=8b+−18
−3b+11=8b−18
Step 2: Subtract 8b from both sides.
−3b+11−8b=8b−18−8b
−11b+11=−18
Step 3: Subtract 11 from both sides.
−11b+11−11=−18−11
−11b=−29
Step 4: Divide both sides by -11.
−11b/−11 = −29/−11
b= 29/11
