Answer:
B (Multiply by 4)
Step-by-step explanation:
In each shape, there are 4 triangles to every square, so the ratio is 4:1
That means that we have to multiply by 4 (B)

Answer: 3/40
Step-by-step explanation:
Number of A's = 4
Number of B's = 5
Number of C's = 6
Number of D's = 5
Total number of letters tiles = 20
Probability of selecting C = 6/20 = 3/10
Probability of selecting D = 5/20 = 1/4
P( C and D)= 3/10 × 1/4 = 3/40
Answer:

Step-by-step explanation:

Move 2a to left hand side and change it's sign
Similarly, move 10 to right hand side and change it's sign
⇒
Collect like terms
⇒
Subtract 10 from 26
⇒
Divide both sides of the equation by 2
⇒
Calculate
⇒

Cut the sign in half across its middle. Then you have two right triangles.
They're congruent, so pick one to work with, and discard the other one
temporarily.
In the right triangle:
-- The length of one leg is 'x'.<em />
-- The length of the other leg is (2x + 7).
-- The length of the hypotenuse is 35.47 inches.
You know that in any right triangle:
(The square of the hypotenuse) =
(the square of one leg) + (the square of the other one.)
so you can use that to find the value of 'x'.
One you know the value of 'x', go back to the whole sign before you cut it
in half, and notice that the height of the sign is '2x' ... which is the answer.
-3x +5y =5
-3x + 5y = 5
5y = 5 + 3x
y=5/5 + 3x/5
y=1 + 3x/5
-2x -4y =-48
same as 2x + 4y = 48
2x + 4 (1 + 3x/5 ) = 48
2x + 4 + 12x/5 = 48
2x +12x/5 = 48-4
10x/5 + 12x/5 =44
22x = 44 times 5 = 220
x = 220/22 =10
x = 10
y = 1 + 3x10/5
y = 1 + 30/5
y = 1 + 6 = 7
y = 7
I believe this is the answer. Hope it helps
