Answer:
B and C
Step-by-step explanation:
(15)
The opposite sides of a parallelogram are equal , so
CD = AB , that is
7x - 54 = 5x - 2 ( subtract 5x from both sides )
2x - 54 = - 2 ( add 54 to both sides )
2x = 52 ( divide both sides by 2 )
x = 26
Then
CD = 7x - 54 = 7(26) - 54 = 182 - 54 = 128 → B
(16)
Consecutive angles are supplementary, sum to 180° , then
6y + 19 + 2y + 9 = 180
8y + 28 = 180 ( subtract 28 from both sides )
8y = 152 ( divide both sides by 8 )
y = 19
Then
∠ B = 6y + 19 = 6(19) + 19 = 114 + 19 = 133°
Opposite angles are congruent , so
∠ D = ∠ B = 133° → C
Step-by-step explanation:
Expression are problems with operations and terms, but no equal sign(s).
<u>Note: If a problem has an equal sign, it's an equation.</u>
*By eliminating the problems with equal signs, 12/4 =3 and 12 = 4 x 3 are incorrect.
12 + 4 - 3 and 12 - 4(3) are expressions, due to both problems not having an equal sign.

Answer:
43 1/3 minutes to iron 10 shirts
Step-by-step explanation:
Number of shirts : Time taken
3 shirts : 13 minutes
10 shirts : x minutes
3 / 13 = 10 / x
Cross product
3 * x = 13 * 10
3x = 130
Divide both sides by 3
3x / 3 = 130 / 3
x = 43 1/3 minutes
x = 43 minutes 20 seconds
It will take 43 minutes 20 seconds to iron 10 shirts
Sum of all the angles in Quadrilateral is equal to 360
so, 360 = 80+110+75+x
x = 360-265
x = 95
