Answer:
x = 32
Step-by-step explanation:
This is an equilateral triangle. This means the angles of the triangle are all equal. Since the sum of a triangle's angles is 180°, that means each angle will be 60°.

Change in temperature = initial - final.
5 -0 = 5.
5°F represents the change in temperature.

Answer:
Option A
Step-by-step explanation:
Weight of an apple = twice of the weight of a lemon
Weight of an apple = 2(weight of a lemon)
x = 2y ------(1)
x = weight of an apple
y = weight of a lemon
Number of apples in a box = 16
Weight of the apple box (A) = 16x
Number of lemons in another box = 24
Weight of the lemon box (B) = 24y
Therefore, 

[From equation (1)]


Option A will be the correct option.
-3x + 4y = 12
x - y = 1....x = y + 1
-3(y + 1) + 4y = 12
-3y - 3 + 4y = 12
-3y + 4y = 12 + 3
y = 15
x - y = 1
x - 15 = 1
x = 1 + 15
x = 16
one solution (16,15)
Answer:
58.05 kg
Step-by-step explanation:
From the table, 1 pound = 0.45 kg
Therefore, 129 pounds = 129* 0.45
