1. For the first question, asking to write an equation for how much more Max needs to save up, It would simply be 95.00 + n = 150.00.
This is because he has $95 and needs $n more to get to the final amount of $150.
2. For the second question, asking which number being substituted for n makes the equation true, isolate n in the equation to find what it equals. To do this, subtract 95 from both sides.
95 + n - 95 = n < This isolates the variable.
150 - 95 = 55
This means n = 55 (fifty five)
3. The inequality is a bit more complicated since it says less than $5 per week. The way I'd do it would get some kind of answer but because I haven't done inequalities like this in a while, I unfortunately can't help you with this part. I can say, however, that it more than likely has something to do with being between two values, but I'm not sure. Sorry for the inconvenience.
Answer:
x=81 degrees z=99 degrees y=68 degrees
Step-by-step explanation:
first we know 36+63+x is 180 degrees by triangle sum ( the sum of the three angles of a triangle is 180) so x would be 81 degrees. then we know x+z=180 degrees by sum of a line( a line is 180 degrees on either side) making z=99 degrees. Then doing triangle sum again we know 13+99+y=180 degrees making y=68 degrees
Answer:
Step-by-step explanation:
We are given the integral of:
First, we can use a property to separate a constant out of integrand:
Next, expand the expression (integrand):
Since then it can be simplified to:
Recall the formula:
For , we need to convert to another identity since the integrand does not have a default or specific integration formula. We know that:
We can solve for which is:
Therefore, we can write new integral as:
Evaluate each integral, applying the integration formula:
Then add all these boxed integrated together then we'll get:
Expand 4 in the expression:
Therefore, the answer is:
1) Let, the original price = x
We know, sale price is 100 - 15 = 85% of original price.
So, x * 85% = 59
x * 0.85 = 59
x = 59/0.85
x = 69.41
In short, Your Answer would be Option B
2) Let, the original price = x
We know, sale price is 100 - 30 = 70% of original price.
x * 70% = 79
x * 0.70 = 79
x = 79/0.70
x = 112.85
In short, Your Answer would be $112.85
Hope this helps!
