Answer:
7x + 6 =8x - 6
x= 12
Step-by-step explanation:
- put them equal to each other
- then subtract 8x from both sides
- 7x(-8x) + 6 = 8x(-8x) - 6
- to get -1x
- then subtract 6 from both sides
- you'll get -1x = -12
- then divide -1 to both sides
- then you get x = 12
Answer:
E. 1/2
Step-by-step explanation:
Divide by 2, then make use of the Pythagorean identity for sine and cosine.
sin(x)^2 +cos(x)^2 = 2a
1 = 2a . . . . . . . sin²+cos²=1
1/2 = a
Answer:
<u>The last step in solving this equation was D. Divide both sides of the equation by 3</u>
Step-by-step explanation:
For finding the solution, let's solve the equation:
7/8 = 3x - 5/11
-3x = - 5/11 - 7/8
-3x = (-40 - 77)/88 (Subtracting at the right side of the equation)
-3x = -117/88
3x = 117/88 (Multiplying by - 1 at both sides of the equation)
x = (117/88)/3 (Dividing by 3 at both sides of the equation)
<u>x = 117/264</u>
<u>The last step in solving this equation was D. Divide both sides of the equation by 3</u>

"<span>Add or subtract. Be sure to reduce your answer: 5\6-9/20"...
To add or subtract rationals, you must find a common denominator of both fractions.
This can be done by multiplying the denominators by each other:
6*20=120
We must do the same operation to the numerators.
5*20=100
9*6=54
Now we can the subtract the rationals:
</span>100/120-54/120
<span>=100-54/120
=46/120
=23/60
Hope this helps.
