Answer:
∠1 = 5 degrees
∠2 = 85 degrees
Step-by-step explanation:
if we add ∠1 and ∠2 that will be 90 degrees (as it is straight angle and its already given in the picture)
( x - 12) + 5x = 90
6x -12 = 90
6x = 90 + 12
6x = 102
x = 102/6
x = 17
Put 17 in both the angles instead of x
∠1 = ( x-12)
= ( 17 - 12)
= 5
∠2 = 5x
= 5 (17)
= 85
now you can even Cross-check
5 + 85
= 90 degrees
Cross-checked

How do you simplify (4m)^5
Answers
Hi! I'm happy to help!
To first solve this, we need to know what is going on. In the order of operations, everything inside of the parenthesis happens first. Since 4 and m are being multiplied inside of the parenthesis, that would happen before being moved to the fifth power. Since m is unknown, we make everything inside of the parenthesis to the fifth power, and make sure they are multiplied together as they are inside of the parenthesis. (Everything inside of the parenthesis applies to the raising to the fifth power.)
[tex]4^{5}[/tex]·[tex]m^{5}[/tex]
From here, we can simplify [tex]4^{5}[/tex] to 1024.
1024·[tex]m^{5}[/tex]
We don't need the multiplication sign because it is a variable.
1024[tex]m^{5}[/tex]
Since we cannot simplify m, this is our most simplified form: 1024[tex]m^{5}[/tex]

Answer:
-2 7/8
Step-by-step explanation:
The usual recommendation is to convert the mixed numbers to improper fractions before multiplying.
[tex]-2\dfrac{5}{9}\times1\dfrac{1}{8}=-\dfrac{9\cdot2+5}{9}\times\dfrac{8\cdot1+1}{8}\\\\=-\dfrac{23\cdot9}{9\cdot8}=-\dfrac{23}{8}=\boxed{-2\dfrac{7}{8}}[/tex]
__
Note the factors of 9 cancel in the first expression on the last line, leaving -23/8.
Answer:
[tex]\frac{23}{8}=2\frac{7}{8}[/tex]
Step-by-step explanation:
[tex]-2\frac{5}{9}\times \:1\frac{1}{8}[/tex]
Step 1: Convert into an improper fraction
[tex]2\frac{5}{9}=\frac{2\times 9+5}{9}\\\\=\frac{23}{9}[/tex]
[tex]-\frac{23}{9}\times \:1\frac{1}{8}[/tex]
[tex]1\frac{1}{8}=\frac{1\times 8+1}{8}\\\\=\frac{9}{8}[/tex]
[tex]-\frac{23}{9}\times \frac{9}{8}[/tex]
Step 2: Cross-cancel 9
[tex]=-\frac{23}{8}[/tex]
Step 3: Convert to an improper fraction
[tex]\frac{23}{8}=2\frac{7}{8}\\\\2\frac{7}{8}[/tex]

8/15 divided by -0.35 as fraction
Answers
(8/15) / (7/20) = (8/15) * (20/7) = (8*20) / (15*7)
= 160/105 = 32/21
Hi, I'm happy to help!
To solve this problem, we can turn -0.35 into an equivalent fraction.
[tex]\frac{8}{15}[/tex]÷[tex]\frac{-0.35}{1}[/tex]
For division, I like to use the strategy called KFC. This stand for Keep, flip, and change. You keep the first fraction, flip the second, and change the operation.
[tex]\frac{8}{15}[/tex]×[tex]\frac{1}{-0.35}[/tex]
Now we multiply the top by the top and the bottom by the bottom.
[tex]\frac{8}{-5.25}[/tex]
We know that the negative applies to the entire fraction, so we write it like this:
-[tex]\frac{8}{5.25}[/tex]

Answers
Answer:
7
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
Ok, so we know 42 is the number of points added up, and we know that she threw 6 darts all scoring the same. Now, all we have to do is figure out what number(for example x) multiplied by 6 equals 42. Or in the form of an equation:
6x = 42
Now, to finish the equation, all we have to do is divide:
6x/6 = 42/6
42/6 = 7
x = 7
