Answer:

Geometric

Ratio = 5:1

Step-by-step explanation:

Geometric sequence is when the relation between the numbers in the sequence is multiplication or division.

For an arithmetic sequence, it is difference as it includes addition or subtraction, but since this sequence is division, we have to use ratios.

The ratio is 5:1 because the previous number is 5 times larger than the following one.

Hope this helps

What is the value of the expression? Show all work. -9 - 6 + 8 ÷ -4 * -2?

nadya68 [22]

Step-by-step explanation:

To do Order of Operations, we need to go with the order of the formula, PEMDAS.

P= Parenthesis

E= Exponents

M= Multiply (Whatever Comes First in Equation: M and D)

D= Divide

A= Addition (Whatever Comes First in Equation: A and S)

S= Subtraction

---------------------------------------------

So, we need to start with parenthesis, there aren't any, so we move on to Exponents.

There are no Exponents either, so we start with division, then multiplication.

(We always have to go left to right).

So,

-9 - 6 + 8 / -4 x -2

-9 - 6 + -2 x -2

-9 - 6 + 4

Our problem is:

-9 - 6 + 4

We do subtraction, then addition. (Left to Right)

-9 - 6 + 4

-15 + 4

-11.

Therefore, the answer is -11.

John received $9,000 in student loans. Part of the money he was able to borrow at 7% simple interest, but on the rest of the mon

lidiya [134]

He borrowed "a" at 7% and "b" at 8.25%

now, whatever "a" and "b" are, we know, his student loan was 9000, thus
a+b = 9000

now, he owes 7% or 7/100 for "a", what's 7% of a? well, 7/100 * a or 0.07a

he owes 8.25% of "b", how much is 8.25% of b? well, 8.25/100 * b or 0.0825b

now, we know, at the end of the year, he owed for both loans, 706.25 in interest
thus we know that 0.07a + 0.0825b = 706.25

thus $\bf \begin{cases}
a+b=9000\implies \boxed{b}=9000-a\\
0.07a+0.0825b=706.25\\
----------\\
0.07a+0.0825\left(\boxed{9000-a} \right)=706.25
\end{cases}$

solve for "a", to see how much he borrowed at 7%

what about "b"? well, b = 9000-a
