How to Solve (3/4+1/2)

Mathematics
1 answer:
Lilit [14]3 years ago

First you want to make the fractions similar.

to do this you need to make the denominators (the botom part of each fraction) the same. 
so you can multiply 1/2 by two DO NOT MULIPLY THE FRACTION AS A WHOLE that would not be good lol 
you will multiply
1*2=2
2-2=4 
now your fraction will be 2/4 

now lets place that back into the equation
3/4+2/4=?
now to solve this the denominators will stay the same.
we only add the top number 
3+2= 5

so our answer will be 5/4 or 1 1/4

grin007 [14]

Answer: 3x-4y+7=3y+1

Step-by-step explanation:

Since there is no negative x positive 4 and no negative number up to 7 that is the same, and since there is no negative number up to 3y or negative 1 the number stays the same so the answer is 3x-4y+7=3y+1

What is the slope of the line that passes through the points (-10, -8) and
bazaltina [42]
First of all we have to find the slope


m = y₂-y₁ / x₂-x₁

m = -8 + 16 / -10 + 8

m = 8/-2

m = -4

y-y₁ = m (x-x₁)

y + 8 = -4 (x + 10)

y + 8 = -4x - 40

y = -4x -40 - 8

y = -4x -48

What is the value of a?
Elan Coil [88]
Note that the interior angles must add up to 180 degrees:  50+62+m<C = 180.
Then 112 + m<C = 180, so that m<C =68 degrees.

Use the Law of Sines to find the value of a, as follows:

sin 50 deg      sin 62 deg
-------------- = ----------------
       a                  31 cm
                                                          31sin 50        31(0.766)
Then 31sin 50 = a*sin 62, and a = --------------- = ---------------- = 26.9 cm
                                                          sin 62              0.883

a =
