Answer:
x>-8
Step-by-step explanation:
multiply both sides with -1
Answer:
1) B/ 0.4n = 12; n = 30
2) B/ 125 – x = 58
3) B/ $1.75
Step-by-step explanation:
1) 0.4n = 12
n = 12 ÷ 0.4
n = 30
2) 125 – x = 58
– x = 58 – 125
– x = – 67 ( – & – will get cancelled)
x = 67
a) 125 + x = 58
x = 58 – 125
x = – 67 (pages won't be in negative)
c) 125 ÷ 58 = x
2.15 = x (wrong)
d) 58 – x = 125
– x = 125 – 58
– x = 67
x = 67 ÷ –1
x = – 67 ( pages won't be in negative)
3) 12x = 21
x = 21 ÷ 12
x = 1.75
Answer:
To find x we use sine
Sine ∅ = opposite/ hypotenuse
x is the opposite
The hypotenuse is 15cm
sin 35° = x / 15
x = 15 sin 35°
x = 8.60
x = 9cm to the nearest tenth
