Answer:

you will pay $69 for 4m of cloth if 1m costs $17.25

Step-by-step explanation:

17.25 x 4 = 69

Step-by-step explanation:

4x=44

x=11

6x+4= 6*11+4= 70

Answer:

6x+4=70

Step-by-step explanation:

To solve this, first, we need to know what x is. To do this, we need to solve the equation:

4x-9=35

The first step to solving this is to add nine to both sides, since we need to do the inverse of subtraction to get our answer.

4x-9+9=35+9

4x=44

Now, do the inverse of multiplying by four, which is dividing by four, to both sides.

4/4x=44/4

x=11

Now that we know what x is, we can find the value of 6x+4. Simply plug in 11 for x.

6(11)+4

66+4

70

Our answer is 70.

Answer:

223 kilograms= 2230000 centigrams

Total weight of fruit:  1/8 + 1/4 + 1.25 = 1.625 pounds

Cost of fruit: 1.625 x 0.80 = $1.30

Cost of cheese = total spent - cost of fruit:

Cost of cheese = 4.05 - 1.30 = $2.75

Answer: $2.75

Answer:

1+2=3

3×0.8=2.4

4.05-2.4=1.65

Step-by-step explanation:

Step-by-step explanation:

x, y are the 2 numbers.

x/y = 9/11

x - y = 6

x = y + 6

now we use that in the first equation

(y + 6)/y = 9/11

y + 6 = 9y/11

11y + 66 = 9y

2y = -66

y = -33

x = y + 6 = -27

but the second equation could also be

y - x = 6

then

x = y - 6

and that in the first equation leads to

(y - 6)/y = 9/11

y - 6 = 9y/11

11y - 66 = 9y

2y = 66

y = 33

x = y - 6 = 27

Answer:

the answer is 1.5 i think

Step-by-step explanation:

Step-by-step explanation:

Given the linear function, w(x) = 3/5x + 2, where the slope, m = 3/5, and the y-intercept is (0, 2).

Start by plotting the y-intercept on the graph. Then, use your slope, m = 3/5 (rise 3 units, run 5 units) to plot other points on the graph.  

Attached is an edited screenshot of your given problem, which shows the plotted points on the graph using the techniques explained in this post.

Answer:

=4/15

=0.26

Step-by-step explanation:

Answer:

x = 4/15

Step-by-step explanation:

Step 1: Multiply both sides by x.

Step 2: Divide both sides by 45.

Therefore, x = 4/15.

Answer: This is false because although -5.8 is a rational number, it is not a integer because the number has a decimal point and only whole numbers are integers.

Answer:

y = 2/3

Step-by-step explanation:

so 12y-3=5, add the 3 to the 5 to get 12y=8. Then divide the 12y by 12 and the 8 by 12. In so you geet y=2/3

Answer:

y is equal to 2 thirds (y = 2/3)

Step-by-step explanation:

12y − 3 = 5

Substitute the given options to see which one will provide a true statement:

If y = 2:

12y − 3 = 5

12(2) − 3 = 5

24 − 3 = 5

21  = 5  (False statement, so it's not the right answer).

If y = 1:

12(1) − 3 = 5

12− 3 = 5

9 = 5  (False statement).

If y = 2/3:

12(2/3) − 3 = 5

8 - 3 = 5

5 = 5 (True statement).

If y = 13:

12(13) − 3 = 5

156 - 3 = 5

153 = 5 (False statement).

Therefore, the correct answer is: y = 2/3.

if it pasts the vertical line check

Step-by-step explanation:

so if there are 2 dots on the same line of a graph it's not a function. or if it's based on x's and y's there can not me x's that are the same number. they can't repeat but y's can!

Answer:

I don't know if you have given the full question.

Step-by-step explanation:

but from what you have typed I understood that ( -x ) = - ( x)

positive × positive = positive

negative × negative = positive

positive × negative = negative

so from this we derive -x = -x ( when we open the bracket negative 1 is multiplied to x)

Answer:

x=1     y=3

Step-by-step explanation:

x+5y=16

x+3y=10

2y=6

y=3

x+15=16

x=1

verify

1+9=10

Answer:

x = 1 , y = 3

Step-by-step explanation:

x + 5y = 16 → (1)

x + 3y = 10 → (2)

Subtract (1) from (2) term by term to eliminate x

0 + 2y = 6

2y = 6 ( divide both sides by 2 )

y = 3

Substitute y = 3 into either of the 2 equations and solve for x

Substituting into (1)

x + 5(3) = 16

x + 15 = 16 ( subtract 15 from both sides )

x = 1

Answer Wen is incorrect. The reason being is that the function does not continue in both directions from the origin. Since we cannot have a negative value of people, we cannot use all values of x as inputs in the equation. Therefore, it is not continuous.

Answer:

Should be D.

Step-by-step explanation:

Because you can't factor the equation you use the quadratic formula. By using it you should get 4 plus or minus the square root of -4 all over 2. Simplified would be 2 plus or minus i

Answer:

The tailor used 3m per baju kurung.

Step-by-step explanation:

The tailor began with 23m of cloth and at the end had 2m of cloth left.  You calculate how many meters of cloth she used all together by subtracting 2 from 23:

    23m - 2m = 21m

Then you find out how many meters she used per baju kurung by dividing 21 by 7:

    21m / 7m = 3m

Answer:

it is solved at jemrare dot com

Step-by-step explanation:

This problem can be solved using distance formula;

s=vt

Here we suppose;

Speed of Tourists=v1=4 km/h

speed of bus=v2=60km/h

Total time to be taken by the tourists to reach the camp without bus=t

Time taken by tourists when bus used=t-2h20min=t-140min

let the total distance is ‘x’ but half is travelled without bus and other half by bus!

for first half distance=s1 =x/2

for second half distance=s2=x/2

Using s=vt formula for first half;
