A parallelogram has two pairs of opposite equal angles.
ABCD so
A = C and B = D

A = 2x + 35
C = 3x - 5

2x + 35 = 3x - 5
35 + 5 = 3x - 2x
40 = x

A = (2 x 40) + 35 = 115
A = C = 115

Sum of angles of a quadrilateral = 360

Angles B and D are equal
So
B = (360 - (115 + 115))/ 2
= 130/2
= 65

B = D = 65

Sue's car used 12 gallons of gas on a 300 mile trip. Jen's car used 5 gallons of gas on a 140 mile trip. Whose car got more mile

vekshin1

Jen's car because if you divide 140 by 5 you get 28 and that's 28 miles per gallon. When you divide 300 by 12 you get 25 and that's 25 miles per gallon.

taurus [48]

Answer : The grain of sand is 50 times greater than the phytoplankton.

Step-by-step explanation :

As we are given that:

Size of phytoplankton = 2 × 10⁻⁶ in

Size of sand grain = 1 × 10⁻⁴ in

Now we have to determine how many times longer the grain of sand is than the phytoplankton.

We are dividing the sand grain size by the phytoplankton size.
