How can I work this problem in adding integers with counters 5 + (-7)

Answer:

$5.35

Step-by-step explanation:

20-14.65=5.35

Answer: B

Step-by-step explanation:

4.5+6=10.5

2 1/2 - 5 1/2 = 2.5 - 5.5 = -3

10.5 - 3 = 7.5

Answer:

4th option

Step-by-step explanation:

The translation shifts Δ ABC → Δ A'B'C'

Consider the x- coordinates of A and A'

A has x- coordinate 1

A' has x- coordinate - 3

Then 1 to - 3 is a shift of 4 units left

Answer:

4 units lefts

Step-by-step explanation:

First you have to take 2 similar points, we will take A' and A and counts the squares between them. Since the dashed A is the new translation, we know the translation is left, all we do now is count the squares which is 4.

Answer:

125

Step-by-step explanation:

If the function is f(x) = 5^x and you need to know the value of f(3), you just need to put 3 in place of x:

f(3) = 5^3 = 5•5•5 = 125

Answer:

the first, third and fourth options are correct

1,7,5,3,6,2

J+B=8

J=6

Joey is 6

you can solve the equestion by many rules , but in my point of view the easiest rule is subtraction/addition and subtition method .

Ans X=11.5

Y = -39

8x+2y=14 eqn.......1

82+2y=4 eqn .......2

2y= -78 (4-82)

y = - 39

putting value of y in eqn ..1

we get,

8x+ 2×(-39) =14

8x= 14+78

8x=92

x = 92÷8

x=11.5

it's a subtition method..

Hey there! I'm happy to help!

Let's have the capacity be c. The tank is currently at 4/5c. We subtract 190 and then we are at 1/6c. Let's set this up as an equation and solve it.

4/5c-190=1/6c

We want to get the c all by itself to see the capacity of the tank. Let's get all of the c values on the left side of the equation and the numbers on the right by using inverse operations.

4/5c-190=1/6c

Add 190 to both sides.

4/5c=1/6+190

Subtract 1/6 from both sides.

19/30c=190

Divide both sides by 19/30.

c=300

So, the capacity of the tank is 300 liters of water.

Here we want to calculate percentages of different values to find your final grade, we can conclude that your final grade will be 73.8

We know that:

you have an average of 62 in homework

you have an average of 93 on quiz

you have an average of 60 on test.

Your final grade will be a 30%-30%-40% of the above average scores, such that the 40% will be of the highest average.

We can see that the highest one is on quiz, then your final grade will be:

the 40% of your average quiz grade plus the 30% of your average homework grade plus the 30% of your average test grade.

This will be:

[tex]g = \frac{40 \%}{100 \%}*93 + \frac{30 \%}{100 \%}*62 + \frac{30 \%}{100 \%}*60\\\\g = 0.4*93 + 0.3*62 + 0.3*60 = 73.8[/tex]

We can conclude that your final grade will be 73.8

Answer:

B one solution

Step-by-step explanation:

Answer:

B - one solution

Step-by-step explanation:

6x+8−2x(7−2)=2(6+1)

Subtract 2 from 7 to get 5.

6x+8−2x×5=2(6+1)

Multiply 2 and 5 to get 10.

6x+8−10x=2(6+1)

Combine 6x and −10x to get −4x.

−4x+8=2(6+1)

Add 6 and 1 to get 7.

−4x+8=2×7

Multiply 2 and 7 to get 14.

−4x+8=14

Subtract 8 from both sides.

−4x=14−8

Subtract 8 from 14 to get 6.

−4x=6

Divide both sides by −4.

x=−46

Reduce the fraction −46 to lowest terms by extracting and canceling out 2.

x=−23

To find the slope, you need to use the slope formula, where m is the slope:

m=[tex]\frac{y_{2}-y_{1 } }{x_{2} -x_{1} }[/tex]

Slope means rise over run, or how much the line rises per the amount the line moves forward. This equation shows the movement from the y points to show rise, over the difference in the x points to show run.

Now, to find the slope we insert our values, starting with our second y point:

m=[tex]\frac{2-y_{1 } }{x_{2} -x_{1} }[/tex]

Now insert our first y point:

m=[tex]\frac{2-4 }{x_{2} -x_{1} }[/tex]

Now we insert our second x point:

m=[tex]\frac{2-4 }{-3 -x_{1} }[/tex]

And finally our first x point:

m=[tex]\frac{2-4 }{-3 -3 }[/tex]

Now, we solve:

m=[tex]\frac{-2 }{-6}[/tex]

So, our slope is -2/-6, to simplify it, we remove both negatives because they cancel each other out.

m=[tex]\frac{2 }{6}[/tex]

Now, we simplify our fraction by dividing the top and bottom by 2:

m=[tex]\frac{1}{3}[/tex]

So, our slope is 1/3. This means that for every 1 unit the line rises, it goes to the right 3 units. The y-intercept is where the line hits the y axis.

If the question is asking for slope intercept form for the equation, you use y=mx+b

y represents any y coordinate on your line, m represents your slope (1/3), x represents any x coordinate on your line, and b represents your y-intercept (3).

If you were to insert these values, you would get:

y=[tex]\frac{1}{3}[/tex]x+3

You use this to find what a y coordinate would be so you can draw your line.

For the next equation we do the same thing:

m=[tex]\frac{y_{2}-y_{1 } }{x_{2} -x_{1} }[/tex]

Insert our values:

m=[tex]\frac{4-1}{2-(-4)}[/tex]

Get rid of the double negative:

m=[tex]\frac{4-1}{2+4}[/tex]

Solve:

m=[tex]\frac{3}{6}[/tex]

Simplify:

m=[tex]\frac{1}{2}[/tex]

Now that we know our slope, let's plug it in to our slope intercept form equation.

y=[tex]\frac{1}{2}[/tex]x+3

Answer:

x is less than -6

Step-by-step explanation:

Add 4 to both sides

-2x is greater than 12

Divide both sides by -2 and don't forget to change the sign

x is less than -6

Answer:

x < - 6

Step-by-step explanation:

Given

- 2x - 4 > 8 ( add 4 to both sides )

- 2x > 12

Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.

x < - 6

Step-by-step explanation:

1) 5a+4b-3a-7b+4a

Add terms having 'a' and 'b' separately

=6a-3b

Now subtitute values of a and b :

=6(-3)-3(4)

=-18-12

=-30

2)c(6-b)-c²

=6c-bc-c²

Subtitute values of b and c:

= 6(-2)-(5)(-2)-(-2)²

=-12+10-4

=-6

3)5x²-2xy+3y

Subtitute values of x and y:

=5(-5)²-2(-5)(-2)+3(-2)

=5(25)-20-6

=125-20-6

=99

4)-k²-(7k-4m)

Subtitute values of m and k:

=-(-2)²-{7(-2)-4(4)}

=-4-(-14-16)

=-4-(-30)

=-4+30

=26

5)3(6x+5y)-2y

Subtitute values of x and y:

=3{6(3)+5(-3)}-2(-2)

=3(18-15)+4

=3(3)+4

=9+4

=13

6)5(3m-n)-4(2m-n)

Subtitue values of m and n:

=5{5(-8)-(-11)}-4{2(-8)-(-11)}

=5(-40+11)-4(-16+11)

=5(-29)-4(-5)

=-145+20

Answer:

Below.

Step-by-step explanation:

In total there are 8 kids. Each cupcake is 2.75 so 8x2.75= 22 now the total is 46.00 So? 46-22 = 24. 24 divided by 2 = 12.

I Divided by 12 because they said cost of each individual cookie.

Answer:

$1.375

Step-by-step explanation:

7guests + 1son = 8children

8 (children) x 2.75 (dollars-per-cupcake) = 22

46 (total cost) - 22 (dollars spend on cupcakes) = 24

24 (left) / 16 (number of cookies needed (each child gets two)) = 1.375

Answer:

5y=4x+2

Step-by-step explanation:

First the slope, the slope is 4/5. Using the slope intercept form, the line of equation is y-2=(4/5)(x-2), 5y-10=4x-8, 5y=4x+2

Step-by-step explanation:

If two lines, segments, or rays intersect at right angles, then they are perpendicular. If two angles are complementary, then their measures add up to 90 degrees. If two angles' measures add up to 90 degrees, then they are complementary. If two angles are supplementary, then their measures add up to 180 degrees.

Answer:

$31,598.33

Step-by-step explanation:

she worked 4+5=9 days.

due the total average we need the total of sales and divide it by the length of the observation period (9 days).

how much did she sell in total on the first 4 days ?

well, the average times 4 = 32130×4 = $128520

how much did she sell in total during the following 5 days ?

31173×5 = $155865

so, the daily average is

($128520 + $155865) / 9 =$284385 / 9 = $31,598.33
