Answer:
x1 = -4; x2 = 10
Step-by-step explanation:
1) Expand the module as two separate equations:
x - 3 = 7
x - 3 = -7
2) Solve the equations:
x = 10
x = -4
=> x1 = -4; x2 = 10
Answer:
-19 degrees
Step-by-step explanation:
13+6=19
you would need to add the negative since it said dropped in temperature and the temperature was already negative.
- Multiply (-2x-4) by -5:
[(-5)(-2x) + (-5)(-4)] +5x - 4 = -29
= 10x+20+5x-4=-29
- Combine Like Terms:
(10x+5x) + (20-4) = -29
15x+16=-29
- Subtract 16 from each side
15x+16 -16 = -29 -16
15x = -45
x = -3
Answer:
If the radius is 6mm, the diameter is 12mm.
If the diameter is 22 ft, the radius is 11 ft.
Step-by-step explanation:
1st one) When you try to find the diameter of any circle, and you already have the radius, you need to multiply it by two (double it)
6 x 2 = 12mm
2nd one) Then to do the opposite, you need to divide the diameter by 2.
22/2 = 11 ft
Hope this helped :)
