He learned and average of 130 words per month when he lived in Portugal and an average of 150 née words per months when he lived in Brazil. In total he learned 1920 new words. How long did wolfrich live in Portugal, and how long did he live in Brazil?

Answers

Answer 1

Answer: Number of months lived in Portugal =9

Number of months in Brazil  = 14-9 = 5

Step-by-step explanation:

Let x= Number of months lived in Portugal , then

Number of months in Brazil = 14 months (As total months he spent in both countries = 14)

Also, as per given,

130(x)+150(14-x)=1920

⇒ 130x+2100-150x=1920

⇒ -20x=1920-2100

⇒ -20x=-180

⇒ x=9  [divide both sides by -20]

Hence, Number of months lived in Portugal =9

Number of months in Brazil  = 14-9 = 5

Andre ran 2 kilometers in 15 minutes, and Jada ran 3 kilometers in 20 minutes. Both ran at a constant speed. In kilometers, How far did Andre run in 60 minutes ?

help ASAP

Answers

Answer:

They did not run at the same speed. Calculation of their speed shows that Jada was running at a higher speed.

Step-by-step explanation:

Let's first calculate the speed of each person using the units provided so that we  do not complicate the question.

speed =  distance covered/time taken

Andre's speed = 2 km/15 min = 0.133 km/min

Jada's speed = 3km/20 min = 0.15 km/min

Clearly we can see that Jada was running at a higher speed than Andre. The question says they were running at constant speed not equal speed. That just means each person maintained their speed, they did not get faster or slower.

Write in slope-intercept form (solve for y): 5x - 2y = 8

Answers

Answer:

y = 5/2 x - 4

Step-by-step explanation:

For slope-intercept form, just solve for y:

5x - 2y = 8

[tex]\frac{5x}{2} - \frac{8}{2} = \frac{2y}{2}[/tex]

5/2 x - 4 = y or

y = 5/2 x - 4

The slope intercept form is y= 5/2x - 4.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

We have the Equation

5x - 2y = 8.

As, we know from the slope intercept form

y= mx + b

So, 5x - 2y = 8

5x - 8 = 2y

5/2x - 8/2 = y

y= 5/2x - 4

where slope is 5/2 and y intercept is -4.

the sale tax rate on groceries in a certain state is 9% if the price of a grocery item before sales tax is g dollars, which expression represents the cost of the grocery item including sales tax?

Answers

Step-by-step explanation:

g + 0.09g = the final price

multiplying 0.09(9/100) with g will give you the tax

then you add it up to get the final cost.

The expression representing the cost of the grocery item including sales tax is 1.09g.

What is Percentage?

Percentage is a dimensionless number and it has no measurement units.

It is usually denoted by the sign %. Sometimes it has also used in the abbreviated form 'pct.'.

Percentage of a number is the quotient of the number dividing with the whole and then multiply with 100. The reverse calculation can be done to find the number corresponding to a percentage.

Price of a grocery item before sales tax = g dollars

Sales tax rate on groceries = 9%

Amount of sales tax = 9% × g

                                 = (9/100) × g

                                 = 0.09 g

Total cost of the grocery = g + 0.09g

                                         = 1.09g

Hence the total cost of the grocery item including sales tax is 1.09g.

Amanda filled her gas tank three times last week. Here are the amounts of gas she bought (in gallons). 10.7,15 , 3.7 What is the total amount of gas Amanda bought last week?

Answers

Answer:

29.4 gallons

Step-by-step explanation:

Given that

the amounts of gas she bought (in gallons). 10.7,15 , 3.7

total amount of gas Amanda bought last week will be sum of 10.7 , 15 and 3.7

total amount of gas Amanda bought last week = 10.7 + 15 + 3.7

=>  total amount of gas Amanda bought last week = 29.4

Thus, Amanda bought 29.4 gallons in total in last week.

Let's solve for b.

x=−5−b+2x

Step 1: Flip the equation.

−b+2x−5=x

Step 2: Add -2x to both sides.

−b+2x−5+−2x=x+−2x

−b−5=−x

Step 3: Add 5 to both sides.

−b−5+5=−x+5
