Answers

Answer 1

Answer:

yes it is correct tq

Step-by-step explanation:

my friend

Answer 2

Answer:

10 quarts.

Step-by-step explanation:

Work with amounts of pure acid.

There is 0.10*3 quarts of pure acid in the 10% solution.

3*0.10 + 0.75x = 0.60(x + 3)    where x is the number of quarts of 75% acid.

0.30 + 0.75x = 0.60x + 1.8

0.15x = 1.5

x = 10 .

Answer:

D, Divide both sides by -4.6

Can someone help me

Answers

Yes it is 10.

Step 1: convert the mixed number to a fraction so now it is 15/2 divided by 3/4

Step 2: flip the second fraction so now it is 15/2 divided by 4/3

Step 3: multiply straight across so 15x4 and 2x3

Step 4: now you have 60/6

Step 5: reduce that and now you have 10

Solve -2(x-5) + 3x = 2(x+3) + 17 *

Answers

Answer:

x=-13

Step-by-step explanation:

Hope this helped :)

Answer:

x = -13

Step-by-step explanation:

-2x + 10 + 3x = 2x + 6 + 17

x + 10 = 2x + 6 + 17

x + 10 = 2x + 23

10 = 2x + 23 - x

10 = x + 23

10 - 23 = x

-13 = x

x = -13

tarting at elevation zero, Zen climbs to an elevation of 4,646.4 feet to reach the Cragway Trail. From there, he hikes up another 1,817.6 feet to the Calloway Peak Summit, the highest point on Grandfather Mountain. Based on these numbers, the Calloway Peak Summit is at a height of
feet.

On his return trip, Zen descends from the Calloway Peak Summit to an elevation of 2,402.5 feet, arriving at the Flat Rock Junction. So, the elevation at Flat Rock is
feet.

Answers

I’m depressed and need someone to talk to :(((((

Answer:

Calloway Peak is 6,464 Feet. And Flat Rock is 4061.5 Feet

Step-by-step explanation:

For Calloway Peak Started at 0 so 4646.4+1817.6=6,464

Zen then descends which means he walked back down 2402.5 feet.

To find Flat Rock you subtract the height of Calloway Peak by 2402.5 the amount that he walked back down to get how tall Flat Rock is in Feet

6464-2402.5=4061.5 Feet

So Flat Rock is 4061.5 Feet tall.
