Answer:x=4 y=-2

Step-by-step explanation:

3x-5y=22

3x+1.5y=9

-6.5y=13

6.5y=-13

0.5y=-1

Y=-2

Replace/substitute

2x-2=6

2x=8

X=4

2x+y=6---------(2)

y=6-2x---------(3)

putting value of y on equation

3x-5y=22

3x-5(6-2x)=22

3x-30+10x=22

13x=22+30

13x=52

x=52/13

x=4

putting value of x on equation (3)

y=6-2x

y=6-2.4

y=6-8

y=-2

Complete question :

The beginning balance of Cooper's savings account for the month of September was $5700, and it remained this way for the first 11 days of the month. On September 12, Cooper made a withdrawal of $900, so his balance changed, and it remained the same for a total of 9 days. On September 20, Cooper made a deposit of $1100, so his balance changed again, and it remained the same for a total of 10 days to finish out the month. Cooper's savings account has an APR of 3.65%, calculates interest daily, and pays interest at the end of the month. Cooper wants to calculate the amount he earned in interest during the month of September.

Part I: What interest rate does Cooper's savings account pay per day?

Part II: How much did Cooper earn in interest during the first 11 days of September?

Answer:

0.01% ; $6.27

Step-by-step explanation:

Given :

Annual percentage interest (APR) = 3.65%

To obtain the daily interest :

APR / Number of days in a year

3.65% / 365

0.0365 / 365

= 0.0001

= 0.0001 * 100

= 0.01%

B.) Interest earned during first 11 days :

Using the relation :

Interest earned = Principal * Rate * Time

Principal = $5700 ; daily rate = 0.0001 ; number of days = 11

Interest earned = (5700 * 0.0001 * 11)

Interest earned = $6.27

Answer:

Approximately [tex]3410[/tex] steps each hour.

Step-by-step explanation:

Given: On Tuesday, Julissa worked from 9:00 A.M. to 3:00 P.M.

Julissa had walked [tex]20,458[/tex] steps preparing orders to be shipped.

To find: Number of steps, approximately, she walked each hour.

Solution: We have,

Total number of steps [tex]=20,458[/tex] steps.

Number of hours, from 9:00 A.M. to 3:00 P.M. [tex]=6[/tex] hours.

So, number of steps she walked each hour [tex]=\frac{20,458}{6} =3409.67[/tex] steps.

Hence, Julissa walked approximately [tex]3410[/tex] steps each hour.

Here, we want to interpret the meaning of the slope

The slope generally refers to the change in y values with corresponding change in x value

with respect to this question, we can see that the slope is negative

What this mean is that the rate of change in the level of oxygen measured in liters is decreasing with an increase in the time

This means that as more time elapses, more oxygen is used up leading to a decrease in the liters of oxygen present

Answer:

[tex]\frac{3}{5} = \frac{18}{30}[/tex]

Step-by-step explanation:

To solve this proportion, we will divide the two given denominators.

Now, we have: 30 ÷ 5 = 6

Next, we will multiply the given numerator by the quotient: 3 × 6 = 18

So, our final proportion will have to be:

[tex]\frac{3}{5} = \frac{18}{30}[/tex]

Answer:

X = 18

Answer:

Each person will pay $9.78

Step-by-step explanation:

Given that:

Amount of bill = $34

Tip = 15%

Amount of tip = [tex]\frac{15}{100}*34[/tex]

Amount of tip = 0.15 * 34

Amount of tip = $5.10

Amount after bill = 34 + 5.10 = $39.10

Number of people = William + three friends = 4

Per person share = [tex]\frac{39.10}{4}[/tex]

Per person share = $9.775

Rounded to two decimal places

Per person share = $9.78

Hence,

Each person will pay $9.78

Step-by-step explanation:

at 3=3

at 0=9

at 4=1

[tex]y = ax + b[/tex]

[tex]1 = 4a + b \\ 3 = 3a + b \\ 2 = - a \\ a = - 2 \\ 1 = - 4 \times 2 + b \\ b = 1 + 8 = 9 \\ y = - 2x + 9[/tex]

Answer:

y=-2x+9

Step-by-step explanation:

From looking at the line you can already tell that the slope is going to be negative, and the y-intercept is going to be 9, since that's where y is when x is 0. You can see that when x is one, y is 7. When x is 2, y is 5. And when x is 3, y is 3.

So:

0: 9

1:7

2:5

3:3

And the difference of y over the difference of x is the slope

-2/1=-2

So the slope is -2

Therefore, putting the equation together makes:

y=-2x+9

Complete question : Two hikers are 33 miles apart and walking toward each other. They meet in 5 hours. Find the rate of each hiker if one hiker walks 2.2 mph faster than the other. The speed of the slow hiker is nothing ​mph, and the speed of the fast hiker is nothing mph.

Answer:

2.2 mph ; 4.4 mph

Step-by-step explanation:

Given that :

Total distance apart = 33

Time taken = 5 hours

Rate of slow hiker = x

Rate of fast hiker = x + 2.2

Speed (rate) = distance / time

Distance = speed * time

Distance covered by fast hiker + distance covers by slow hiker

(x + 2.2)*5 + 5x = 33

5x + 11 + 5x = 33

10x = 33 - 11

10x = 22

x = 22 / 10

x = 2.2

Rate of slow hiker = 2.2 mph

Rate of fat hike = x + 2.2 = 2.2 + 2.2 = 4.4 moj

Answer:

Rhian did better in the Math test.  

Step-by-step explanation:

Given: Rhian scored [tex]14[/tex] out of [tex]17[/tex] in a Math test. In the English test she scored [tex]31[/tex] out of [tex]39[/tex].

To find: In which test did she do better?

Solution:

We have,

Rhian scored [tex]14[/tex] out of [tex]17[/tex] in a Math test.

Rhian scored [tex]31[/tex] out of [tex]39[/tex] in an English test.

So, first we need to find the percentage of the marks scored.

Percentage in the Math test [tex]=\frac{14}{17}\times100=82.35 \%[/tex].

Percentage in the English test [tex]=\frac{31}{39}\times100= 79.49\%[/tex].    

Clearly, the percentage in the Math test is greater than the percentage in the English test.

So, Rhian did better in the Math test.
