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°.

PLEASEEE HELP!!! Need help pls
borishaifa [10]

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, \frac{A}{B}=\frac{16x}{24y}

\frac{A}{B}=\frac{2x}{3y}

\frac{A}{B}=\frac{2(2y)}{3y} [From equation (1)]

\frac{A}{B}=\frac{4y}{3y}

\frac{A}{B}=\frac{4}{3}

Option A will be the correct option.

Which statement is true about the equations –3x + 4y = 12 and x – y = 1?
Firlakuza [10]
-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)
