Answer:
C. 5 3/10
Step-by-step explanation:
After adding the red strips count up the yellow blocks (13 in all)
take away 10 because that makes 1 whole
3 left over out of that 10
4 red strips + 10/10 + 3/10 = 5 3/10
Answer:
Multiply he second equation by -3
The solution is (0, 2)
Step-by-step explanation:
When doing this, you make it so you can eliminate the x variables...
start with
3x + 6y = 12
x + 5y = 10
Now multiply the second equation by -3
-3(x + 5y = 10) becomes...
-3x - 15y - 30
Now our system is
3x + 6y = 12
-3x - 15y = -30
When we add them together, we get
-9y = -18
***The x variable is gone, so we have eliminated that
Here is the final solution in case you need it..
-9y = -18 solve for y..
y = 2 (divide by -9 on both sides to isolate y)
There for x is
x + 5(2) = 10
x + 10 = 10
x = 0
so the solution is (0, 2)
Answer:
B
Step-by-step explanation:
4^2 = 16
Answer:
4/663
Step-by-step explanation:
(4/52)×(4/51)
= 4/663
= 0.00603
Answer:
second option : the side length was multiplied by 5.
Step-by-step explanation:
a = side length of the original square
A² = a×a
(a+5)×(a+5) = a² + 10a + 25
and that should be equal to a²×25
a² + 10a + 25 = 25a² ?
10a + 25 = 24a²
no, that is not true for all a
a×5 × a×5 = a²×25 = 25A²
this is the correct solution, as it is true for all a.
