17h +1= [3h-7| for h.

Seventy minus the product of 8 and a number is 86 as an equation

Alinara [238K]

Hey there!!

Let us take the number as ' x '

7 - 8x = 56

-8x = 49

x = -49/8

Hope helps!

The amount of money jorge earns for (h) hours of work can be expressed as 100 + 25 (h) which inequality represents the number of

insens350 [35]

Answer:

This means jorge must work for at least 36 hours to earn $1,000. The inequality that represent this expression is h $\geq$ 36

Step-by-step explanation:

Given the amount of money jorge earns for (h) hours of work expressed as 100 + 25 (h). If jorge must work to earn at least $1,000, this means that the lowest amount jorge can earn is $1,000. Jorge cannot earn below but above $1000 i.e he will always earn amount greater than or equal to $1,000.

The statement can be represented using the inequality;

100+25h $\geq$ 1000

To know the number of hours jorge must work to earn at least $1000, we can solve the inequality function for 'h'

Subtarcting 100 from both sides;

100+25h-100 $\geq$ 1000-100

25h $\geq$ 900

dividing both sides by 25

$\frac{25h}{25} \geq \frac{900}{25} \\h\geq 36$

This means jorge must work for at least 36 hours to earn $1,000

If there are approximately 1.8 million cars in Vancouver and if each car travels an average of 17,500 kilometres in a year, how

Goryan [66]

Rates are used to measure a quantity over another.

The 1.8 million cars use $1.85 \times 10^{10}$ liters each year

Given

$Cars = 1.8\ million$

$d = 17500km$ --- distance

$r = 40miles/gallon$

First, we calculate the number (n) of gallons used by each car

$r = \frac{d}{n}$

Solve for n

$n = \frac{d}{r}$

So, we have:

$n = \frac{17500km}{40miles/gallon}$

$n = \frac{17500km}{40miles}gallon$

Convert miles to kilometers

$n = \frac{17500km}{40km \times 1.60934}gallon$

$n = \frac{17500km}{64.3738km}gallon$

$n = 271.85\ gallon$

The number of gallons (N), used by all the cars is:

$N = n \times cars$

$N = 271.85 \times 1.8\ million$

$N = 489330000$

Convert to liters

$N = 489330000 \times 3.78541L$

$N = 1852314675.3L$

In scientific notation to 2 decimal places, we have:

$N = 1.85 \times 10^{10}L$

Hence, the number of liters used is $1.85 \times 10^{10}$

Write 93/50 as a percentage.

elena55 [62]

Answer: 186%

To get this simply divide 93 into 50 (you will get 1.86 which you can convert to the percentage 186%). An even easier way is to multiply 93 by two (186) since 50% times 2 is 100%. Hope this helps!
