Answer:
129 points
Step-by-step explanation:
Let L and C represent the scores of Luke and Caleb, respectively.
L = 2C -15 . . . . . Luke scored 15 less than twice the number Caleb did
L +C = 201 . . . . . they scored 201 points altogether
Add twice the second equation to the first:
2(L +C) + (L) = 2(201) + (2C -15)
3L +2C = 387 +2C . . . . simplify
3L = 387 . . . . . . . . . . . . .subtract 2C
L = 387/3 = 129 . . . . . . .divide by 3
Luke scored 129 points.
π * Diameter = 39.8in
Diameter = 12.67in
Since 18in is greater than 12.67in, the ring is not large enough for his act.
Answer:
In 5:
UM and MS are equal since the diagonals US and VT have perpendicularly bisected each other.
So,15=6x-3
15+3=6x
18=6x
3=x
In 6:
ET=TC
8=x-4
8+4=x
12=x
Answer:
11 : 22 : 132
Step-by-step explanation:
1 + 2 + 12 = 15
165 ÷ 15 = 11
1 × 11 = 11
2 × 11 = 22
12 × 11 = 132
11 : 22 : 132
