The easiest literal equations to understand are formulas where one variable is expressed in terms of the others. To solve for a given variable, isolate that variable on one side of the equation so that it's solved in terms of the other variables. Make sure to use the same operations on both sides of the equation!
Answer:
X = -4, y = 3
Step-by-step explanation:
Plug it in
-3x - 3(-5x - 17) = 3
-3x + 15x + 51 = 3
12x + 51 = 3
12x = -48
x = -4
plug it in to find y
Y = -5(-4) -17
y = 20 - 17
y = 3
300/150 = 2 days is how long one case will last. 7/2 = 3.5 cases needed to last 7 days. So, you need a total of 4 cases in order to have enough soap.
Answer:
Yes, the sequence is an arithmetic sequence
Step-by-step explanation:
Notice that each consecutive number is being added by the next odd number up:
0+3=3
3+5=8
8+7=15
15+9=24
24+11=35
We can represent this as the arithmetic sequence
