Answer:
The answer is 120, 80, 100, 180, 40, 0, 240
Step-by-step explanation:
In this situation, quadrupling means to times everything (everything which is 30, 20, 25, 45, 10, 0, 60) by 4, which will give you 120, 80 ,100 ,180, 40, 0, 240
26+a
(12+a)+14
(12+14)+a
<u><em>Answer: x=-17 and -17=x. *The answer should be the negative sign.*</em></u>
subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
a-c=b-c
subtract by 5 both sides of an equation.
x+5-5=-12-5
simplify.
12+5=17
17-5=12
17-12=5
x=-17 and -17=x
Hope this helps!
Thanks!
Have a great day!
Answer:im not sure i wish i can help but goodluck

31.2*10^3
We know that 10^3 is 1 with 3 zeros = 1000
31.2 *1000
Multiplying by 1000 moves the decimal 3 places to the right
