Your question is incomplete, here is the complete form.
Points J, K and L are collinear with J between L and K. If KJ = 2x - 3, LK = 9x + 7 and LJ = 4x - 8, solve for x:
Answer:
The value of x is -6 ⇒ B
Step-by-step explanation:
∵ J, K, and L are collinear
→ That means they form a straight segment
∵ J is between K and L
→ That means J divides LK into two segments KJ and LJ
∴ LK = KJ + LJ
∵ LK = 9x + 7
∵ KJ = 2x - 3
∵ LJ = 4x - 8
→ Substitute them in the equation above
∴ 9x + 7 = (2x - 3) + (4x - 8)
→ Add the like terms in the right side
∵ 9x + 7 = (2x + 4x) + (-3 - 8)
∴ 9x + 7 = 6x + -11
∴ 9x + 7 = 6x - 11
→ Subtract 7 from both sides
∵ 9x + 7 - 7 = 6x - 11 - 7
∴ 9x = 6x - 18
→ Subtract 6x from both sides
∵ 9x - 6x = 6x - 6x - 18
∴ 3x = -18
→ Divide both sides by 3
∵
∴ x = -6
∴ The value of x is -6
Answer:
Step-by-step explanation:
Assuming this pizza is a circle, we can use this formula for area:
1. Find Radius
We are given the diameter: 12 inches, but the formula uses radius.
The radius is half the diameter, or:
2. Calculate Area
Substitute the radius (6 inches) in for r. The question also asks us to use 3.14 for pi.
Solve the exponent.
- (6 in)²= 6 in* 6 in= 36 in²
Multiply.
3. Round
The question asks us to round to the nearest tenth.
The 4 in the hundredth place tells us to leave the 0 in the tenth place.
The area of the pizza is about 113.0 square inches.
