You can isolate the variable by subtracting 6 from both sides.
e.g.
x + 6 = 13
- 6 - 6
Now we have x = 7, which not only isolates the variable but solves for x.
If you don't know why we can subtract from both sides, look up the Addition Property of Equality and Subtraction Property of Equality.

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $3820 and his stock in Company B was worth $2960. The stock in Company A has increased 15% since last year and the stock in Company B has increased 5%. What was the total percentage increase in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Answer:
10.6%
Step-by-step explanation: Find new values:
3820(1+0.15)=\color{green}{4393}
3820(1+0.15)=4393
2960(1+0.05)=\color{blue}{3108}
2960(1+0.05)=3108
Last Year This Year
Stock A 3820 4393
Stock B 2960 3108
Total 6780 7501
\text{Find overall increase:}
Find overall increase:
6780(1+r)=7501
6780(1+r)=7501
\frac{6780(1+r)}{6780}=\frac{7501}{6780}
6780
6780(1+r)
=
6780
7501
1+r=1.106342
1+r=1.106342
r=0.106342
r=0.106342
Subtract 1
\text{Final Answer: }10.6\%
Final Answer: 10.6%

consider the expression 7 - 4y. Why would the co-efficient be -4 and not 4?
Answer:
because a co-efficient is the multiplicative factor in polynomials and it's minus 4 before the y. you would just take the minus and put it with the 4 otherwise it would just be floating there ig.

3. Find the values of the variables and the lengths of the sides of this kite.
y - 3
x+2
2x+2
x+11
A. x = 9, y = 14; 11, 20
B. x = 14, y = 9; 11, 11
C. x = 14, y = 9; 6, 16
D. x = 9, y = 14; 6, 16
Answer:
So, the correct option is A. x = 9, y = 14 , Sides are 11 and 20
Step-by-step explanation:
P.S - the exact question is -
As given in the question ,
Side AB = Side AD
⇒y - 3 = x + 2
⇒y - x = 2 + 3 = 5
⇒y - x = 5 .........(1)
Also, given
Side BC = Side CD
⇒2x + 2 = x + 11
⇒2x - x = 11 - 2
⇒x = 9
∴ equation (1) becomes
y - 9 = 5
⇒y = 5 + 9 = 14
⇒y = 14
∴ we get
x = 9, y = 14
Now,
as given ,
Side AB = y - 3
⇒ AB = 14 - 3 = 11
Side BC = 2x + 2
⇒ BC = 2(9) + 2 = 18 + 2 = 20
Side CD = x + 11
⇒ CD = 9 + 11 = 20
Side DA = x + 2
⇒DA = 9 + 2 = 11
∴ we get
The sides are 11 and 20
So,
The correct option is A. x = 9, y = 14 , Sides are 11 and 20
I need help with 1 - 4 please
Answer:
I'll help u with #1 then u can do the others hopefully
Step-by-step explanation:
y=mx+b
1. slope=m
slope=1.5 so y=1.5x+b
y-intercept=b
y-intercept=5 (because (0, 5) means x is 0 and y is 5, which is that point)
Answer: y=1.5x+5
The present value in a savings account is $420. It is receiving 3% annually compounded monthly. What is the future value in 2 months?
Answer:
$422.10
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Present value (PV) = $420
Rate of interest( compounded monthly) = 3% annually
so, rate of interest per month (r) = 3 ÷ 12 = 0.25% per month
Time period (n) = 2 months
so, by putting the value in excel FV formula, we get.
Attachment is attached below.
Future value in 2 months = $422.10
