Answer:

7

Step-by-step explanation:

Given expression:

        4x + 2y  = 36

  coordinates  = (a,4)

Solution:

  From the given coordinates;

       x = a

       y = 4

       4x + 2y  = 36

 Substitute for the values and find "a"

    4a + 2(4)  = 36

     4a + 8  = 36

     4a  = 36 - 8

     4a  = 28

      a  = 7

The solution is 7

Answer:

8 wristbands

Step-by-step explanation:

Let us assume that both of the company were ordered to deliver w wristbands.

The amount of money charged by company 1 who sells at $2 and offers free shipping is given as:

2w

The amount of money charged by company 2 who sells at $1.25 and $6 for shipping per order given as:

1.25w + 6

If both companies charge the same amount, hence:

2w = 1.25w + 6

2w - 1.25w = 6

0.75w = 6

w = 6/0.75

w = 8

The two companies charge the same amount for 8 wristbands

Total number of parts = 5 + 7 + 8 = 20

Let the sum of the money with them be = x

Cleopatra has =

= 5/20 of x = $17

= 5/20x = 17

= 1/4x = 17

= 1x = 17 × 4 ( transposing ÷4 from LHS to RHS changes ÷4 to ×4 )

= x = 68

Therefore , they have $68 in total .

Total number of parts = 5 + 7 + 8 = 20

Parts with Dalila = 7/20

Money with Dalila =

= 7/20 of 68

= 7/20 × 68/1

= 476/20

= 23.8

Dalila has $23.8 with her .

Money she spends on a hat = $12

Money left with her =

= 23.8 - 12

= 11.8

Therefore , Dalila has $11.8 left with her , after she buys a hat .

Solution to the problems in the comment box :-

Ratio of cement to sand to aggregate to water = 2:5:8:1

Total parts = 2 + 5 + 8 + 1 = 16 parts

Number of parts for aggregate = 8/16

Then the aggregate needed by Bobbie =

= 8/16 × 1.2

= 1/2 × 1.2

= 1.2 as a fraction will be 6/5

= 1/2 × 6/5

= 6/10

6/10 as a decimal = 0.6

Therefore , Bobbie needs 0.6 cube of meter .

Cement : sand : aggregate : water = 2:5:8:1

Total parts = 16

Number of parts for cement = 5/16

Let the quantity of concrete be = x

Then ,

Cement =

= 5/16 of x

= 5/16x = 0.25 meter cube

= x = 0.25 × 16/5

= x = 25/100 × 16/5

= x = 1/4 × 16/5

= x = 16/20

= x = 4/5

4/5 as decimal = 80/100 = 0.08

Cement needed by Eddie = 0.08 cubic meter .

Quantity of water Eddie will need =

= 1/16 × 0.08

= 1/16 × 80/100

= 1/16 × 8/10

= 8/60

= 0.13

Water needed by Eddie = 0.13 cubic meter .

Quantity of aggregate needed by Eddie =

= 8/16 × 80/100

= 1/2 × 8/10

= 8/20

= 40/100

= 0.04

Aggregate needed by Eddie = 0.04 cubic meter .

Quantity of sand Eddie will need =

= 5/16 × 80/100

= 5/16 × 8/10

= 40/160

= 0.25

Quantity of sand needed by Eddie = 0.25 cubic meter .

Therefore , Eddie will need 0.25 cubic meter of sand , 0.04 cubic meter of aggregate ,0.13 cubic meter of water along with 0.25 cubic meter of cement to make concrete .

When water and aggregate has been added the quantity of concrete =

= 0.13 + 0.04

= 0.07

Therefore , when water and aggregate has been added the quantity of concrete will be 0.07 cubic meter .

Answer:

6 miles per hour or 6 miles

Step-by-step explanation:

If Karis can run 1 mile in 10 minutes, how many miles could he run in 1 hour at this same rate?

1 mile = 10 minutes

there are 60 minutes in 1 hour

10 minutes × 60 minutes = 6

6 × 1 mile = 6 miles so the answer is 6 mile per hour

Answer:

About 5 and a half

Step-by-step explanation:

Given :

A local company offers a monthly plan for 58.95 dollars.

The company is having a sale and offering a discount of 4.75 off the monthly plan.

To Find :

Sam says that the new cost is 11.45 explain Sam's error and find the correct new cost.

Solution :

Correct cost = Original price - Discount offered

Correct cost = $( 58.95 - 4.75 )

Correct cost = $54.2 .

Now, Sam's cost is $11.45 because he took $4.75 as $47.5 .

Hence, this is the required solution.

Answer:

D) 132.67 (this seems to be the closest to the answer, I hope it helps)

Step-by-step explanation:

First, have the area of circle formula: A = π r²

Then, you need to find the radius to be able to complete the area formula. So, since you have the circumference, you will need to use it to find the radius:

C = 2 π r

40.82 = 2 π r

20.41 = π r

r = 6.496704777 . . . Do not round! Rounding will not give an exact answer!

Now that you have the radius, plug in:

A = π r²

   = π (6.49 . . .)²

   = π  (42.20717296 . . .) Do not round! Rounding will not be exact!

   = 132.5977445 . . .

   ≈ 132.6

Answer:

(8x/2)-6=5

Step-by-step explanation:

Answer:

B would be the answer because line c goes through a and b. line c would the 180 line. if you subtract 180 with the numbers on lines a and b, they would equal the same.

Option B is right.

What are corresponding angles?

Corresponding angles are those angles formed in the same relative position on different intersections when a pair of lines are crossed by a third line.

Here, if we see the 60° angle, then the opposite angle must be = (180° - 60°) = 120°.

This equal to the given corresponding angle , which is also 120°.

We know, if the corresponding angles of a pair of lines are equal, then the pair of lines must be parallel.

Hence, Option B is correct.
