Answer:

-9 = x

Step-by-step explanation:

Since this is an isosceles triangle, the <em>two</em> base angles are congruent, therefore you have this:

180° = 70° + 2[x + 64] \\ 180° = 70° + 2x + 128 \\  \\ 180 = 198 + 2x

- 198 - 198

-18 = 2x

Answer:

-9

Step-by-step explanation:

The triangle has two sides that are the same, so it is an isosceles triangle.  Therefore, the base angles are the same.

Angles of a triangle add up to 180°, so:

70 + (x + 64) + (x + 64) = 180

70 + 2x + 128 = 180

2x = -18

x = -9

Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

(7x - 1) + (13x - 19) = 180

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                    20x - 20 = 180
  2. Isolate <em>x</em> term:                              20x = 200
  3. Isolate <em>x</em>:                                       x = 10

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                    (7(10) - 1) + (13(10) - 19) = 180
  2. Multiply:                               (70 - 1) + (130 - 19) = 180
  3. Subtract:                              69 + 111 = 180
  4. Add:                                     180 = 180

Here we see that 180 does indeed equal 180.

∴ x = 10 is the solution to the equation.

Last year, 31 2 acres of strawberry fields produced approximately 14,700 pounds of strawberries. This year the number of acres p
USPshnik [31]

So in 5 acres of land produces 21,000 pounds of strawberries.

Step-by-step explanation:

Step 1:

Last year, 3\frac{1}{2} acres i.e 3.5 acres produced 14,700 pounds of strawberries. So we need to determine how many strawberries were produced per acre.

To do this we divide the total number of strawberries produced by the number of acres it was produced in.

The number of strawberries produced per acre= \frac{14,700}{3.5} = 4,200 pounds.

Step 2:

To determine the number of strawberries in 5 acres of land, we multiply the number of strawberries per acre by the number of acres.

The number of strawberries produced in 5 acres= 5(4,200) = 21,000 pounds.

So in 5 acres of land produces 21,000 pounds of strawberries.
