Answer:
a. 49
Step-by-step explanation:
so, basically turn the equation around! -15+64. because -15 is in parentheses, we know that it is negative, but another way you can do it is to take away the addition symbol and just use the negative as a subtraction one. so you could do 64-15 and you get 49. for b it's a little different, two negative cancel each other out so because there's a subtraction sign after 18 and there's a negative sign before 55 you can see that to simplify the equation it would be -18+55 or again 55-18. for c I think that one is pretty simple, just do 92-86 (I don't know if you see the pattern yet but most times you can just flip it around.) and for d you can do 17 plus 44 and then make the solution negative. I hope this helped a little!!

Answer:
5y+25= 30y
5y+5= 10y
8x-12= -4x
4x+24= 28x
Step-by-step explanation:
If you see a math problem with one variable (letters) and one a number by itself, the anwar will always be the variable after the number you had answar like for EXAMPLE: 1x+1= 2x
Answer:
The value of the slope is 6
Step-by-step explanation:
To get the slope of the line, we are going to make use of the slope equation
Mathematically, we have this as;
m = (y2-y1)/(x2-x1)
where (x1,y1) = (1,2) and (x2,y2) = (2,8)
Substituting these values;
m = (8-2)/(2-1) = 6/1 = 6
Okay first if you want to find the angle of 4, you have to complete the first triangle's angles.
So since the 2 angles that are in the triangle are 25° & 52<span>°
Then you add them together and get 77</span><span>°
Next you subtract 77</span>° from 180°, so you should get 103<span>° for angle 3
Finally you subtract 103</span>° from 180° to complete line segment ←PAL
Final Answer: 77<span>°</span>
