Answer: The sequence rule is division. 80 divided by 2 = 40 divided by 2 = 20 divided by 2 = 10 and 10 / 2 equals 5.
Step-by-step explanation:
The sequence is divided by 2 because when you divided 80 by 2, it equals the second pattern in the sequence, 40.
I worked it out by dividing every number by 2 and getting the same numbers in the pattern, I checked by doing the opposite, 40 x 2 = 80.
Hope this helps!
The simpliest way to do this is to turn both fractions into decimals
7/10 goes to 0.7 and 2/5 goes to 0.4
then the equation would be 0.7x + 20 = 0.4
hope I've helped!
Answer:
Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time. Each of these equations on their own could have infinite possible solutions.
Answer: 30.5 and 35.5
Step-by-step explanation:
We can use a system of linear equations to find out the answer to this problem. The larger number will be x and the smaller number will be y.
x=y+5
x+y=66
Substitute y+5 in for the bottom equation to get y+5+y=66. Simplify to get 2y+5=66. Subtract 5 from both sides and get 2y=61. Divide by 2 to get y=30.5. This is the smaller number. Add 5 to get the bigger number, which is 35.5
