Answer:6y= -5x + 3
Step-by-step explanation:
Answer: The answer is A, 40.
2 x 2 = 4 + 4 x 4 = 16
4 + 16
= 20 + 2 x 40
20 + 80 = 100
(x = 40)
Answer: £60
Step-by-step explanation:
Natalie bought a pair of shoes for £54 which had been reduced by 10%.
To find the original cost, assume the original cost is x.
The discount would be: 10% * x
The expression would therefore be:
x - (10% * x) = 54
x - 0.1x = 54
0.9x = 54
x = 54 / 0.9
x = £60
Answer:
X = 20
Step-by-step explanation:
The angle are supplementary:
- Meaning that the two angles = 180°
Equation:
Solve:
- 7x + x + 20 = 180
- 8x + 20 -20 = 180 - 20
- 8x = 160
- Divide 8 from both sides:
- <u>x = 20</u>
