Let the amount of shells collected by Aaron be
and the amount of shells collected by Maria be
respectively. Then the following system of equations should be solved:
First of all, express
out of first equation:
Then, replace
in second equation with found expression and solve it:
Finally, replace
in first equation with found value and solve it too:
So, Aaron has found
7 shells while Maria has found
21.
Answer:
-6
Step-by-step explanation:
We are given x=- 3 , y= 6 and z= -4.
We are also given the expression:
-15 + (-x) +y
Substitute -3 in for x and 6 in for y.
-15 + (- -3) + 6
2 negative signs creates a positive sign
-15 + (+3) +6
-15 + 3+ 6
Add -15 and 3.
(-15+3) +6
-12 +6
Add -12 and 6.
-6
-15+(-x)+y evaluated at x= -3 and y=6 is equal to -6.
Answer:
AD = 3
Step-by-step explanation:
Pythagoras theorem formula: a² + b² = c² (c being the hypotenuse, the longest side of the triangle).
Using this formula, you can easily say that c²-b²=a². c=5, b=4, making the equation 5² - 4² = a ².
Expanding the formula, you'll get 25 - 16 = a².
25 - 16 = 9.
This means that 9 = a².
To find a, you need to root 9. Using a calculator, you'll know that this number is 3, meaning that AD = 3.
Answer:
- Translation
Step-by-step explanation:
Movement of a rigid object from one place to another without any turning is "translation." If the object also changes its orientation angle, then rotation is involved.
When you divide 98 by 5194, you get 0.01886 to be almost exact
