Examine parallelogram ABCD below.
gtnhenbr [62]

Given that,

∠C = (6x-21)° and ∠A = (4x+11)°

To find,

Choose the correct option.

Solution,

For a parallelogram, the opposite angles are equal. ATQ,

(6x-21)° = (4x+11)°

Taking like terms together,

6x-4x = 21 + 11

2x = 32

x = 16

∠C = (6x-21)° = 6(16) -21 = 75°

So, ∠A = 75°

So, ∠A = ∠C = 75°. Hence, the correct option is (B).

Which statement is false? A. (−2)×5&lt;(−20) B. (−2)×(−5)&gt;(−25) C. 2×5&gt;(−25) D. 2×(−5)&lt;20
natali 33 [55]

Answer:

(−2)×5<(−20)

Step-by-step explanation:

Evaluating the options given :

(−2)×5<(−20)

Open the bracket

- 10 < - 20 (false) ` This expression isn't true

(−2)×(−5)>(−25)

Open the bracket

10 > - 25 (true)

2×5>(−25)

Open the bracket

10 > - 25 (true)

2×(−5)<20

Open the bracket

- 10 < 20

Find two numbers whose sum is 50 and whos difference is 22
pentagon [3]

Answer:

36 and 14

Step-by-step explanation:

Create an equation

x+x-22=50

Combine like terms

2x-22=50

Add 22 on both sides

2x=72

divide 72 by 2

x=36

subtract 22 from 36

14+36=50

Hope this helps! :P

Angela and you are painting a room. Angela has 2 1/2 gallons of blue paint and Ryou has half as much white paint. It will take 2
GREYUIT [131]
Conversion from gallons to quarts

1 gallon = 4 quarts

Now,

Angela has 2 \frac{1}{2} gallons = 2\frac{1}{2} *4 = 10 quarts of blue paint

Ryou has 1/2 of what Angela has = 1/2*10 = 5 quarts of white paint.

Each wall requires 2 \frac{3}{4} of paint.
After coloring;
Blue colored walls = (10)/(2 \frac{3}{4}) = 3 walls with 7/11 quarts of paint remaining.
White colored walls = (5)/(2 \frac{3}{4}) = 1 wall with 9/11 quarts of paint remaining
