Answer:

x = -13

Step-by-step explanation:

angles 1 and 5 are congruent (equal) because they are classified as 'corresponding'

-3x + 69 = -5x + 43

2x = -26

x = -13

Answer:

108°

Step-by-step explanation:

$- 3x + 69 = - 5x + 43 \: \: \\ (corresponding \: \angle s) \\ \\ 5x - 3x = 43 - 69 \\ \\ 2x = - 26 \\ \\ x = \frac{ - 26}{2} \\ \\ x = - 13 \\ \\ - 5x + 43 = - 5( - 13) + 43 \\ = 65 + 43 \\ = 108 \degree \\ \\ \because m \angle \: 4 = - 5x + 43 \\ (vertical \: \angle s) \\ \\ \huge \red{\therefore \: m \angle \: 4 } \pink{=} \purple{ 108 \degree}$

Give one number that makes the inequality x + 7 > 20 true

Zigmanuir [339]

For example smallest x which makes inequelity is x =14
because 14 + 7 = 21 > 20

you can take any number >= 14

It takes 60 minutes to make 2000 copies on an old copy machine. The newer copier works with the old copier to create 2000 sheets

Cerrena [4.2K]

The new copier can create 2000 copies in 20 minutes.

Step-by-step explanation:

Given,

It takes 60 minutes to make 2000 copies by old printer and 15 minutes to made x number of copies, therefore, using proportion

$60:2000::15:x$

Product of mean = Product of extreme

$2000*15=60*x\\30000=60x\\60x=30000$

Dividing both sides by 60

$\frac{60x}{60}=\frac{30000}{60}\\x=500$

As the new copier is working with old copier, therefore,

Copies made by new printer = 2000 - 500 = 1500

New copier can make 1500 copies in 15 minutes and 2000 copies in x minutes, using proportion

$1500:15::2000:x\\1500*x=15*2000\\1500x=30000$

Dividing both sides by 1500;

$\frac{1500x}{1500}=\frac{30000}{1500}\\x=20$

The new copier can create 2000 copies in 20 minutes.
