Answer:
b = d/(2ac)
Step-by-step explanation:
10abc - 2d = 3d
Add 2d to each side
10abc - 2d+2d = 3d+2d
10 abc = 5d
Divide each side by 10ac
10 abc/ (10ac) = 5d/10ac
b = d/(2ac)
The commutative property means that the numbers can be switched when multiplying. The second one shows the associative property, where the numbers can be grouped differently. The third one shows the identity property, where multiplying by 1 will get the same number you are multiplying it by. The fourth one shows the zero property, where multiplying by zero will get zero.
Therefore, the answer is the first one because the numbers are simply flipped.
Answer:
D)
Step-by-step explanation:
I don't know if there was a picture, but d will made a triangular prism. All are possible but they will look more like a dome.
Let's solve for x.
Step 1: Add -3x to both sides.
Step 2: Add -8 to both sides.
Step 3: Divide both sides by 4.
Answer:
AC = 10sin40°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = = , then
sin40° = ( multiply both sides by 10 )
10sin40° = AC
