Answer:
CB= 4
Step-by-step explanation:
the triangles are in AA similarity.
AB/AD = BC/DE
4/12 = x/12
CROSS MULTIPLY;
x = 48/12
x = 4
Answer:
=4/3
Step-by-step explanation:
Step 1
Multiply the denominator by the whole number
6 × 1 = 6
Step 2
Add the answer from Step 1 to the numerator
6 + 2 = 8
Step 3
Write answer from Step 2 over the denominator
8/6
=86
You can also reduce this fraction.
Find the Greatest Common Factor (GCF) of 8 and 6, if it exists, and reduce our fraction by dividing both numerator and denominator by it,
GCF = 2
=8÷2=4
6/2=3
Simplified Solution
=6×1+2/6 =8/6=4/3
hope this helps
you welcome and thanks
820 + .06(820)
820 + 49.2
869.2
The cost of the car is $869.20.
For this problem I would change:
2x + 3y = 25 into
-2x - 3y = -25
Then, I would add up both equations by lining them up top of another.
5x + 3y = 31
+ -2x - 3y = -25
3x = 6
x = 2
Now that you have x, solve for y.
5x + 3y = 31
5(2) + 3y = 31
10 + 3y = 31
3y = 21
y = 7
So, x is 2 and y is 7.
Check to see if the values are correct by plugging them into the other equation.
2x + 3y = 25
2(2) + 3(7) = 25
4 + 21 = 25
25 = 25
Since the values are correct, the solution to this problem is A (2, 7).
These would all be correct!
