Answer:
Step-by-step explanation:
No. of blue n(B) = 5
No. of red n(R) = 3
Total marble is N = 8
P(R) = n(R)/N
= 3/8
First, find the area of the entire traingle using the formula bh/2.
18*9/2=81 cm^2
Then subtract the area of the smaller triangle within the larger one (white triangle). It has the same base but a height of only 4.
18*4/2=36 cm^2
81-36=45
Final answer: 45 cm^2
A= base x height = 3x4 = 12 ft
Answer:
x = 1/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
10−2x=19x+2−5x
10+−2x=19x+2+−5x
−2x+10=(19x+−5x)+(2)(Combine Like Terms)
−2x+10=14x+2
−2x+10=14x+2
Step 2: Subtract 14x from both sides.
−2x+10−14x=14x+2−14x
−16x+10=2
Step 3: Subtract 10 from both sides.
−16x+10−10=2−10
−16x=−8
Step 4: Divide both sides by -16.
−16x/−16 = −8/−16
x = 1/2
