A=b/c -b/d
a+b/d=b/c
(da+b)/d=b/c
db=(da+b)c
c=db/da+b
Answer: x=4
Step-by-step explanation:
The perimeter´s formula for this kind of polygons is
The triangle perimeter would be:
(x+2)+(x+3)+(x+3)
And the rectangle:
(x+2)+(x+2)+x+x
For them to have the same value, we should equal them:
(x+2)+(x+3)+(x+3)=(x+2)+(x+2)+x+x
Working with this:
3x+8=4x+4
x=4
Answer:
<em>37%</em>
Step-by-step explanation:
Add up the percentages and subtract them by 1.00:
- 35% & 28% = 0.35 & 0.28
- 0.35 + 0.28 = 0.63
- 1.00 - 0.63 = 0.37
- 0.37 = 37%
Good luck! :)
Answer:
120 different possible lunch specials
Step-by-step explanation:
To calculate the overall number of possible lunch specials that can be made we would need to multiply together all of the options from each one of the items found in the lunch special. These values are provided in the question so we can simply multiply them all together to calculate the total possible lunch specials that can be made...
- Salads=3
- Soups=2
- Sandwiches=5
- Drinks=4
3 * 2 * 5 * 4 = 120 possibilities
Finally, we can see that there are a total of 120 different possible lunch specials that can be made with the availble options.
Answer: y = -x - 1
<u>Step-by-step explanation:</u>
Use the Point-Slope formula: 
where
- (x₁ , y₁) is the given point (0, -1)
Insert those values into the formula and solve for y:
y - (-1) = -1(x - 0)
y + 1 = -x
y = -x - 1
