The answer to your problem is 17

Not sure if you meant n-\frac{63}{m} or \frac{n-63}{m}

if it was the first one then 26-\frac{63}{7}=26-9=17
if it was the 2nd one then \frac{26-63}{7}=\frac{-37}{7}


I would assume it is the first one because it simplifies to a nice fraction

major each of the following angles write it measures right weather it is acute ,obtuse, right angle A straight angle or a reflex
Leya [2.2K]

Answer:

i = right angle

ii = obtuse angle

iii = straight angle

iv = obtuse angle

v = acute angle

Step-by-step explanation:

an acute angle is an angle less than 90 degrees

an obtuse angle is an angle more than 90 degrees

a right angle is an angle equivalent to 90 degrees (looks like two straight lines perpendicular)

a straight angle is an angle equivalent to 180 degrees (looks like a straight line)

a reflex angle is an angle greater than 180 degrees

so, ...

i = right angle

ii = obtuse angle

iii = straight angle

iv = obtuse angle

v = acute angle

Equivalent ration of <br> b/40=9/10<br> b=____ ?
NARA [144]

Answer:

The correct answer is <em>b = 36</em>

Step-by-step explanation:

In order to find out what b is, you must find out what 9/10 is.

9/10 is 0.9. This will later be used to check our answer.

Now, solve by using cross-multiplication

b * 10 = 9 * 40.

Then use the commutative property to reorder the terms

10b = 9 * 40

Now Multiply 9 * 40 = 360

10b = 360

Now divide both sides of the equation by 10

<em>b = 36</em>
