Greetings ! Your Answer Is Below.
Answer;
1. m = 16
2. x = -z + 34 or z = -x + 34
3. p = 49
Step-by-step explanation;
1. m + 13 - 13 = 29 - 13 | Subtract 13 from both sides ( m = 16 )
2. - z + 34 | Add -z to both of the sides ( x = - z + 34 )
Or - x + 34 | Add -x to both of the sides ( z = - x + 34 )
3. 136 - 87 = 49 | Subtract 87 from both sides ( p = 49 )

X=hours master worked
y=hours apprentice worked
62x+40y=492
if master worked 3hours more than apprntice
x=3+y
sub 3+y for x
62(3+y)+40y=492
expand
186+62y+49y=492
186+102y=492
minus 186 both sides
102y=306
divide both sides by 102
y=3
sub back
x=3+y
x=3+3
x=6
master electrician worked 6 hours
6*62=372
master electrician earned $372
Answer:
x >1/5
Step-by-step explanation:
5x-1 >0
Add 1 to each side
5x-1+1 >0+1
5x >1
Divide each side by x
5x/5 >1/5
x >1/5
19x³ + (14x + 4x³)=
You can assume that there is a 1 in front of the parentheses, so you can distribute the one to each term in the parentheses.
19x³ + 1(14x+4x³)=
19x³ + 14x + 4x³=
Then combine like terms to get 23x³ + 14x.
So 19x³ + 14x + 4x³= 23x³ + 14x
Answer:
x=5, y=-3, x=-4, y=9
Step-by-step explanation:
1. x=5, is a vertical line cutting the x axis at 5
2. y=-3 is a horizontal line cutting the y axis at -3
3. x= -4, is a vertical line cutting the x-axis at -4
4. y=9, is a horisontal line cutting the y-axis at 9
