Answer:
Number of students in a student group = 8
Step-by-step explanation:
Let number of student in a student group = x
∴ Kevin lead 150 adults and 6x students
⇒Kevin lead = 150 + 6x
And,
Monica lead 134 adults and 8x students
⇒Monica lead = 134 + 8x
So, the number of students are equal
⇒150 + 6x = 134 + 8x
⇒150 - 134 = 8x - 6x
⇒16 = 2x
⇒x = [tex]\frac{16}{2}[/tex] = 8
∴ we get
Number of students in a student group = 8

Raphael deposited $6,500 in an account that pays 4.25% interest, compounded annually. He left the money in the account for 4 years, without depositing money to it or withdrawing money from it.
At the end of the 4 years, how much interest in dollars and cents did the account earn? help asap
Answer:
$1105
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4.25%/100 = 0.0425 per year,
then, solving our equation
I = 6500 × 0.0425 × 4 = 1105
I = $ 1,105.00
The simple interest accumulated
on a principal of $ 6,500.00
at a rate of 4.25% per year
for 4 years is $ 1,105.00.

2 + x = 19
what does x equal
Answer:
x = 17
Step-by-step explanation:
2 + x = 19
Subtract 2 on both sides to isolate the variable
2 - 2 + x = 19 - 2
x = 17
Check
We can check by distributing the "x" with 17 since thats what we got as the value.
2 + x = 19
2 + 17 = 19
19 = 19
CORRECT
Hope this helped!

Answer:
127.3 feet
Step-by-step explanation:
Using the Pythagorean Theorem, you would start with 90² + 90² = __²
90² = 8,100

Now you have to square root 16, 200
√16,200 = 127.27922...
Rounded to the nearest tenth is: 127. 3 ft

SMART PPL PLEASE HELP ,Explain how you know the expression represents the area of shaded part of the rectangle.
Answer:
6(m-2)
Step-by-step explanation:
Alright. Let's start by finding the length of this shaded area. The full length of the rectangle is 'm', and the part that is not shaded has a length of '2', so if we subtract the full length and the non-shaded length, we will get the shaded part's length. This is 'm-2'. The width/height we already know...it is 6, so-
Answer is: 6(m-2)
Answer:
6(m-2)
Step-by-step explanation:
it is 6(m-2) because you would do the whole length of m minus 2.

Find the solution of the system of equations -7x-3y=-20 3x+6y=-15
9514 1404 393
Answer:
(5, -5)
Step-by-step explanation:
I like a graphing calculator for quickly finding a solution to a system of equations. It shows the solution to be (5, -5).
__
We can add the second equation to 2 times the first to eliminate the y-variable.
2(-7x -3y) +(3x +6y) = 2(-20) +(-15)
-11x = -55 . . . . . collect terms
x = 5 . . . . . . . . . divide by -11
Substituting this value into the second equation, we have ...
3(5) +6y = -15
6y = -30 . . . . . . . . subtract 15
y = -5 . . . . . . . . . . divide by 6
The solution is (x, y) = (5, -5).

you invest 10000 that will earn 8.3% every year how much will you earn in 12 years.
Answer:
$16034.03
Step-by-step explanation:
I'm going to assume it's compound interest
10000(1+.083)^12
26034.03
subtract the original amount to find out how much was earned
26034.03-10000=16034.03
Answer:
$9960 would be earning in 12 years
Step-by-step explanation:
8.3% of 10,000 is 830
1% of 10,000 is 100
.3 would just be 30
.4 would be 40
etc etc
so 830 times 12(years) is $9960.00
