Answer:

-15

Step-by-step explanation:

6.8(6.7 – 7.2) – 2(4.6 + 1.2)

The first step in PEMDAS is to do whatever's in the parenthesis. So, this would be the 6.8 bit.

6.8 times 6.7 is 45.56 and then 6.8 times 7.2 which is 48,96

Now we can also do the second set of parenthesis. 2 times 4.6 is 9.2, and 2 times 1.2 is 2.4

The equation now reads- (45.56 - 48.96) - (9.2 + 2.4)

All we have to do is evaluate what's in the parenthesis, the first set equals -3.4 and the second set equals 11.6

So, now our expression reads, -3.4 minus 11.6 which equals -15

Julia drinks 8 cups of water per day. How many quarts of water dose she drink per day
jenyasd209 [6]
So, we need to find out how many 8 cups is converted to quarts. 

1 cup = 0.25 quart

Now that we know the 1 cup equals 0.25 quarts, we can multiply how many cups by the amount of one cup.

8 (cups of water) × 0.25 (equal of one cup) = 2 quarts

Julia drinks <span>2 quart</span>s of water per day.

I have 30 ones, 82 thousands, 4 hundred thousands, 60 tens, and 100 hundreds. What number am I?
stich3 [128]
This problem tackles the place values of numbers. From the rightmost end of the number to the leftmost side, these place values are ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions, ten millions, one hundred millions, and so on and so forth. My idea for the solution of this problem is to add up all like multiples. In this problem, there are 5 multiples expressed in ones, thousands, hundred thousands, tens and hundreds. Hence, you will add up 5 like terms. The solution is as follows

30(1) + 82(1,000) + 4(100,000) + 60(10) + 100(100)

The total answer is 492,630. Therefore, the number's identity is 492,630.

-104=-8(k+8) <br><br> K = ?<br> Solution please if can?
maksim [4K]

Let's solve this question by step by step.

Layout equation.

−104=−8(k+8)

Step 1: Simplify both sides of the equation.

−104=−8(k+8)

−104=(−8)(k)+(−8)(8)(Distribute)

−104=−8k+−64

−104=−8k−64

Step 2: Flip the equation.

−8k−64=−104

Step 3: Add 64 to both sides.

−8k−64+64=−104+64

−8k=−40

Step 4: Divide both sides by -8.

-8k/-8=-40/-8

The answer for this problem is k=5.
