PLEASE HELP IF YOUR GOOD AT ALGEBRA
LUCKY_DIMON [66]

9514 1404 393

Answer:

  lower left

Step-by-step explanation:

We notice that the answer choices have only the first equation changed. The equivalent of the first equation must have the same ratios of coefficients.

  x-coefficient : y-coefficient : constant

  = 2 : 1 : -15 . . . . . in the given equation

  2 : -2 : 30 = 1 : -1 : 15 . . .  upper left — not the same

  -4 : -2 : -15 = 4 : 2 : 15 . . . upper right — not the same

  -4 : -2 : 30 = 2 : 1 : -15 . . . lower left — same as the given equation

  -4 : 1 : 30 = 4 : -1 : -30 . . . lower right — not the same

Please help, I’m struggling
Naddika [18.5K]

Answer:

49.5 mi

Step-by-step explanation:

Area of a triangle is   A = (height) X (base) / 2

So if you plug in the numbers you get:

806.9 = (32.6) X (base) / 2

1613.8 = (32.6) X (base)

1613.8 / 32.6 = base

base =  49.5 mi

Help needed ! 13 - 2(2x + 1) = 1 ?
kirill115 [55]

Answer:

x = ¹⁰⁄₄,⁵⁄₂, or 2.5

Step-by-step explanation:

Given: 13 - 2(2x + 1) = 1

1. Distribute -2 through the parentheses:

⇒ 13 - 2(2x + 1) = 1

⇒ 13 + (-2)(2x) + (-2)(1) = 1

13 - 4x - 2 = 1

2. Combine like terms:

⇒ 13 - 4x - 2 = 1

⟹ 11 - 4x = 1

3. Subtract 11 from both sides:

⇒ 11 - 11 - 4x = 1 - 11

⟹ -4x = -10

4. Divide both sides by -4:

⇒ -4x ÷ -4 = -10 ÷ -4

⟹ x = ¹⁰⁄₄,⁵⁄₂, or 2.5

5. Check your work:

⇒ 13 - 2(2x + 1) = 1

⇒ 13 - 2(2(2.5) + 1) = 1

⇒ 13 - 2(5 + 1) = 1

⇒ 13 - 2(6) = 1

⇒ 13 - 12 = 1

⟹ 1 = 1 ✔
