Step-by-step explanation:

$10a-25+5b\\\\-2(-5a-25+5b)=(-2)(-5a)+(-2)(-25)+(-2)(5b)\\=10a+50-10b\qquad NOT\\\\(2a-5+b)(5)=(2a)(5)+(-5)(5)+(b)(5)=10a-25+5b\qquad YES\\\\10(a-2.5+0.5b)=(10)(a)+(10)(-2.5)+(10)(0.5b)\\=10a-25+5b\qquad YES\\\\(-2a+5-b)(-5)=(-2a)(-5)+(5)(-5)+(-b)(-5)\\=10a-25+5b\qquad YES\\\\-10(-a-2.5-0.5b)=(-10)(-a)+(-10)(-2.5)+(-10)(-0.5b)\\=10a+25+5b\qquad NOT$

Find the value of z.

nataly862011 [7]

Answer:

z = $\frac{50}{3}$

Step-by-step explanation:

The ratio of corresponding sides are equal, that is

$\frac{z}{10}$ = $\frac{20}{12}$ ( cross- multiply )

12z = 200 ( divide both sides by 12 )

z = $\frac{200}{12}$ = $\frac{50}{3}$

If you scale down the ratio on the left, what will you get for the unknown quantity on the right? 434 miles14 gallons = ?2 gallo

jarptica [38.1K]

Answer:

option (A) 62 miles

Step-by-step explanation:

Data provided in the question:

Ratio on the left = 434 miles : 14 gallons

ratio on the right = ?? : 2 gallons

Now,

The ratio on the both sides are equal

let the unknown value in the ratio be 'x'

Now, the ratio a : b can also be represented as $\frac{a}{b}$

therefore,

434 miles : 14 gallons = x : 2 gallons

or

⇒ $\frac{\textup{434 miles}}{\textup{14 gallons}}$ = $\frac{\textup{x}}{\textup{2}}$

or

⇒ x = $\frac{\textup{434 miles}}{\textup{14 gallons}}\times2 gallons}$

or

⇒ x = 62 miles

Hence,

the correct answer is option (A) 62 miles
