Answer:
subtract 3 from to both sides. then you have -5n = -25. then you divide -5 to both sides to get n = 5.
Step-by-step explanation:
the same as the answer because you wanted it in word form.
So its 20t+1.75 because each ticket is 20 dollars, so when you substitute 3 into t, the answer is 61.75
Hey there! :)
Answer:
x = 12.
Step-by-step explanation:
Given:
Cross multiply to solve for x:
3 · 20 = 5 · x
60 = 5x
Divide by 5:
12 = x.
The altitude of an equilateral triangle:
h = s √3 / 2, where s is the length of one side of the triangle.
s √3 /2 = 7 √ 3 / : √3
s / 2 = 7
s = 7 * 2
s = 14 units
Answer:
B ) 14
For this case, we have that:
- By definition, a rectangle is a parallelogram. So, we discard the first option.
- On the other hand, we have that all rectangles can not be squares, since a square has all its sides equal, while the rectangle, poir definition, no.So, we discard the second option.
- All quadrilaterals are not rectangles because there are other figures with four sides that are not necessarily rectangular. We discard the third option.
- Finally, we have that all squares are rectangles. This statement is true since squares can be rectangles with pairs of equal sides.
