Answer:
2x+3=-13
x=5
Step-by-step explanation:
it says 2 times a number which would be the 2x, and it says the sum of that and 3 which would be 2x+3 and it says is 13. 2x+3=13
now solving it
2x+3=13
subtract 3 from both sides
2x=10
and divide 2 from both sides
x=5
Answer:
Equation: 2n+3 = -13 Number: -8
Step-by-step explanation:
Ok so, it states the sum of twice a number and 3 equals -13. The question states to consider the number as "n" so the equation is 2n + 3 = -13.
Subtract 3 on both sides. Now . you have 2n = -16.
Divide 2 on both sides.
n = -8

I'll use the formula for compounding interest.
A = P(1+r/n)^nt
A = future value of the loan including interest
P = principal of the loan
r = interest rate
n = number of times the interest is compounded per year (monthly=12)
t = number of years the money is loaned for
Given:
P = 12,450
r = 7.3%, compounded monthly
t = 10 years
A = 12,450 (1+0.073/12)^12*10
A = 12,450 (1.006)¹²⁰
A = 12,450 (2.05)
A = 25,522.50
25,522.50 - 12,450 = 13,072.50 total interest paid.
The correct answer will be option A.

Answer:
(8 × 10) + (10 × 10) = 80 + 100 = 180 minutes
Step-by-step explanation:
It is given that, Jack reads his book for 8 minutes before school and 10 minutes after school.
No of days between Monday to Friday = 5
No of days between Monday to Friday in 2 weeks = 10
We need to find how many minutes Jack reads his book in two weeks.
For 10 days, before school = (8 × 10) min = 80 minutes
For 10 days, after school = (10 × 10) min = 100 minutes
It means, total time will be :
T = (8 × 10) min + (10 × 10) min
T = 80 + 100
T = 180 minutes
Hence, the correct option is (C).

1.- Calculate the distance from FG
dFG =
dFG =
dFG =
dFG =
dFG = = 7.07
2.- Calculate the distance from GH
dGH =
dGH =
dGH =
dGH = 10
3.- Calculate the distance from FH
dFH =
dFH =
dFH =
dFH =
dFH = = 7.07
4.- Calculate the perimeter
Perimeter = 7.07 + 10 + 7.07
= 24.1 units

given that A and B are parallel, you can conclude that 30 = x - y since they are corresponding angles. Also you can conclude that 5y = 2x since they are alternate interior angles. At this point, there is a solvable system of equations set up
30 = x - y
5y = 2x
Now, you must isolate a variable so let's isolate x from the 1st equation. so u just need to add y to both sides, getting x = 30 + y. Now you plug that into the 2nd equation and solve for y. 5y = 60 + 2y. Subtract 2y from both sides. 3y = 60. Divide by 3, y = 20.
Now with your y value, just plug back into original equation (the 1st one). 30 = x - 20. Solve for x by adding 20. X = 50

What are Mathematical operators?
A collection of numbers and operations is an expression in mathematics. The following are the parts of a math expression that do a math operation:
Operands: Operands are the numbers that an operator uses. The terms that are given to the operands vary according to the kind of operation.
Given money received by Angelina in the first week = $10
and money she will get each week for rest of the year = $10
amount in first week = $10
amount in second week = $10 + $10 = $20
amount in third week = $20 + $10 = $30
amount is week 52 = 52 x $10 = $520
table for the week and money
week 1 2 3 4 5 6 ........ 52
money $10 $20 $30 $40 $50 $60 ....... $520
Hence the amount after 1 year will be $520.
