Answer:
(7-5)
Step-by-step explanation:
According to PEMDAS, parenthesis go first. But there are two sets of parenthesis so the one inside the other goes first.
Next would be [3+(2*2)]
Then, [3+4]
Then, -8/1
Then, -3(7)
So the question would be 4-8-21
Which gives you -25 as an answer.
I realize that you weren't asking for the whole thing but maybe there are follow up questions.
The answer is x equals -1
Answer:
32 or 34 I multiply 18 by 4 to get it
Answer:
b = 0.7w
Step-by-step explanation:
To make a shade of blue paint :
3 1/2 quarts of blue
5 quarts of white
3 1/2 α 5
7/2 = 5k
Where k is the proportionality constant
k = 7/2 ÷ 5
k = 7/2 * 1/5
k = 7/10
k = 0.7
To mix :
b quartz of blue with w quartz of white
b = kw
b = 0.7w
Answer:
B is correct
Step-by-step explanation:
In order to simplify a square root, look at the number inside the square root. See its factors. For this problem, 100*2=200. The square root of 100 is 10, which you would take outside of the square root. This leaves 2 inside the square root, which cannot be further simplified.
