7 0

Answer:

Sacing 490 spending 420

Step-by-step explanation:

If a is a fraction

Saving 7a Spending 6a

7a + 6a = 910

13a = 910

a = 910/13

a = 70

Saving 7×70 = 490

Spending 6×70 = 420

The sum is 490 + 420 is equal to 910

Simplify the expression. Write your answer using only positive exponents:7^6 x 7 x 7^-4
svetoff [14.1K]
The problem is asking you to simplify the exponents.  When you multiply two or more powers with the same base, the exponents can be added and subtracted.  In this case, the base is 7.

7^6*7*7^{-4}

7 can also be written as 7^1.

7^6*7^1*7^{-4} = 7 ^{(6+1-4)} = 7^3

The answer would be 7³ if you kept the exponent, or 343 if you simplified further.

In Science class, Mrs. Olson had 30.6 pounds of metamorphic rock. Mrs. Olson had to divide the rocks into 9 different containers
JulijaS [17]

The answer is 3.4 because 30 can’t be divided equally into 9, reason being that 9 x 30 = 270 which doesn’t make sense, so you have to divide 30 equally into 9 parts then turn it into a ratio.
