Answer:
6
Step-by-step explanation:
Purple = p
Blue = b
Step 1: Write as an algebraic equation.
p = 4b - 6
p + b = 49
Step 2: Rearrange p + b = 49 to make p the subject.
p + b = 49
p = 49 - b
Step 3: Write p = 4b - 6 and p = 49 - b into one equation.
p = 4b - 6 = 49 - b
Step 4: Move all b values onto one side.
p = 5b = 55
Step 5: Find the value of one blue marble.
5b = 55
b = 11
Step 6: If there are 11 blue marbles and there are 49 marbles in total, then find the number of purple marbles.
p = 49 - b
p = 49 - 11
p = 38
ANSWER:
There are 38 blue marbles.
Step-by-step explanation:
1. AB = BC (B is the midpoint of AC)
2. DE = EF (E is the midpoint of DF)
3. EB is common
4. ∠ABE = ∠CBE; ∠BED = ∠BEF (EB⊥AC, EB⊥DF)
5. ΔDEB ≅ ΔFEB (RHS)
6. DB = FB (corresponding ∠s of ≅ Δs)
7. ∠EFB = ∠CBF; ∠EDB = ∠ABD (alternate interior angles, AC║DF)
8. ΔABD ≅ ΔCBF (SAS)

Answer:
we will use Pythagorean's Theorem

Therefore, the missing leg is 15 meters long.
Step-by-step explanation:
we will use pythagoras theorem
Given that,
One leg of the triangle is 20 meters long,
the hypothenuse is 25 meters long,
and the leg missing is called x.
we will use Pythagorean's Theorem

Therefore, the missing leg is 15 meters long.
