Really !
If zero is a solution, then you can put it in place of 'x' and the statement will be true.
x > -3
Put zero in place of 'x':
Zero is greater than -3 .
Is that true ?
(Hint: Yes, it's true.)
Then zero is a solution.
Answer:
Step-by-step explanation:
Joint variations occurs when one variable depends on the value of two or more variables. The variable varies directly or indirectly with the other variables combined together. The other variables are held constant. From the given examples, the equation(s) that represent joint variations are
1) z = 3x/y
z varies directly with x and inversely with y.
2) w = abc/4
w varies inversely with a,b and c. 4 is the value of the constant of variation.
Answer:
Each cookbook cost $15.15.
Step-by-step explanation:
Since the statement indicates that four cookbooks and one novel cost $68.75, you can write the following equation:
4x+y=68.75, where:
x is the price of cookbooks
y is the price of novels
Also, given that the novel cost 7 dollars less than a cookbook, you can write the following equation:
x=y+7
Now, you can replace x=y+7 in the first equation:
4(y+7)+y=68.75
4y+28+y=68.75
5y=40.75
y=40.75/5
y=8.15
Now, you can replace the value of y in x=y+7:
x=8.15+7
x=15.15
According to this, the answer is that each cookbook cost $15.15.
6 lots can be created
<em><u>Solution:</u></em>
Given that neighborhood development that is 4 acres is to be divided into 
acre lots
To find: number of lots created
From given information,
Total acres = 4
one lot = 
So number of lots created can be found by dividing the total acres by acre of 1 lot
<em><u>Thus the formula is:</u></em>
<em><u>Substituting the values we get,</u></em>
Thus 6 lots can be created
Answer:
Step-by-step explanation:
There are two sides on a coin, heads and tails. So, the probability of flipping heads is going to be 1/2, as there is one chance out of the two options that you will flip a head. As for spinning blue, there are 3 options that are blue out of the four color options given. So, the probability of spinning blue would be 3/4. Hope this helped :) Take this with a grain of salt, though. It's been a while since I reviewed probabilities.
