Answer:
D
Step-by-step explanation:
2(1) + 4 = 6
2(2) + 4 = 8
2(3) + 4 = 10
For Q3, you can subsitute x = 2 and y = 5 into the systems
-5(2) + 5 = -5
so it's a solution for the first system
-4(2)+2(5) = 2
it's also a solution for the second system
Answer:
Step-by-step explanation:
Let the numbers be x and y.
<u>We have:</u>
<u>Sum the two and find x:</u>
<u>Find y:</u>
Answer: If Percentage decrease % = 20%, (1 - Percentage decrease %) = 1 - 20% = 100/100 - 20/100 = 80/100 = 0.8 => Percentage decreased number = 0.8 × Initial value
Step-by-step explanation: Number 100 decreased by 20% (20 percent) of its value (percentage decrease) and calculated absolute change (actual difference)
Put the number in the formula and do the arithmetic.
C = (5/9)(329 - 32)
C = (5/9)(297)
C = 165
The temperature in °C is 165.
