Answer:
100 hours
Step-by-step explanation:
it's very simple just reduce it to 1 carpenter 1 hour and 1 chair
What 2 numbesr multiply go get -6 and add to get 1
-2 and 3
(x-2)(x+3)=0
set each to zero
x-2=0
x=2
x+3=0
x=-3
{2,-3}
Answer:
The total monthly cost would be $214
explanation:
They gave us 1,250, which is half of 2,500. multiplication:
1,250 = 2,500
107 = x
2 × 1,250 = 2,500
2 × 107 = 214
Therefore, the total monthly cost if the cell phone is used for 2,500 minutes is $214.
Answer:
x=31°, y=52°,z=97°
Step-by-step explanation:
The interior angles of a triangle sum up to 180°
y°+ 31°+ 97°= 180°
y° = 180 - 31° - 97°
y=180°-128°
y° = 52°
Alternative angles are equal
x= 31°
Two opposite angles of a parallelogram are equal
z°= 97°
Therefore x=31°,y=52° and z=97°
The last choice is correct.
