I am guessing this is an expression that needs to be simplify or factorise or both.
If the expression goes like this and I repeat :
2 1/2 x - 3/4 (2x+5) + 3/8
5x/2 - 3x/2 - 15/4 + 3/8
5x/2 - 6x/2 - 27/8
-x/2 - 27/8
-(4x + 27)/8 Answer:
Please comment me back if I got the question incorrect.
Answer:
a) 37º
b) 143º
c) 2x - 5 = 143
Step-by-step explanation:
a) Angles 5 and 7 are vertical angles and therefore have the same measurements.
b) Angles 5 and 6 form a straight line and are therefore supplementary (add up to 180º). 180 - 37 = 143.
c) We found the measure of angle 6 is 143º in part b. We can set that equal to 2x - 5. Therefore the equation is 2x - 5 = 143.
Answer:
4
Step-by-step explanation:
The fraction reduces to 4/7
Answer:
the answer is 10 you round up a nine it keeps going to the end
If you add them straight down:
2d-e = 7
d + e = 5
Then the e's cancel out.
You are left with 3d = 12
Then solve for d by dividing each side by 3.
Now you have d =4.
To solve for e go back into one of your original equations and substitute 4 for the d.
You can use either equation, so I'll choose the second one.
4 + e = 5
Now solve for e by subtracting each side by 4.
Now you have e = 1.
So your solutions are d = 4 and e = 1
