2x - 4y = 32
2x - 8y = 48
2x - 2x - 4x - (-8y) = 32 - 48
4x = -16
x = -16 ÷ 4
x = -4
substitute your value of x into any of the original equations
2 (-4) - 4y = 32
-8 - 4y = 32
-4y = 32 + 8
-4y = 40
y = 40 ÷ -4
y = -10
Answer:
<5 = 132°
<7 = 132°
<8 = 48°
Step-by-step explanation:
aAgle 2 and angle 5 are supplementary which means their sum is 180° so angle 5 is 180 - 48 = 32°
Angle 5 and angle 7 are congruent so their measures are equal 132°
Angle 8 and angle 2 are congruent and equal to each other as well
The answer would be B. All you would do is subtract 6.4 - 2.06 and you would annex a zero after the four. Then you would get 4.34
Answer:
1 ans 6
2 ans 4
3 ans 8
because if x equals zero then its basic arithmetic
£7200
In first year depreciates by 20%, that is it is worth 80% of it's original value
80% =
= 0.8
value after 1 year = 0.8 × £10000 = £8000
In the second year it depreciates by 10% of it's value, that is it is worth 90% of it's value at the end of the first year.
90% =
= 0.9
value after 2 years = 0.9 × £8000 = £7200
