Answer:

y=8-6x

Step-by-step explanation:

Answer:

y=0

x=4/3

Step-by-step explanation:

6x+y=8

x =8-y/6

substitute 8-y/6 in second equation

42*8-y/6 +7y=56

7(8-y) +7y=56

56-y+ 7y=56

-y+ 7y=0

6y=0

y=0

6x+y=8

6x+0=8

x=8/6

x=4/3

Answer:

A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself.

In mathematics, the sieve of Eratosthenes is an ancient algorithm for finding all prime numbers up to any given limit. It does so by iteratively marking as composite the multiples of each prime, starting with the first prime number, 2

given x+1 > 10,

x > 10 - 1

x > 9

which means x MUST BE more than 9 , which also means 9 isnt included in the inequality therefore x = 9 is not a solution.

Answer and Step-by-step explanation:

First, get theta by itself.

θ = [tex]sin^{-1}(\frac{\sqrt{3} }{2} )[/tex]

Plug this into a calculator.

θ = 60°

To get it in radians, multiply 60 by [tex]\frac{\pi }{180}[/tex].

θ = [tex]\frac{1}{3} \pi[/tex] radians

Answer:  

C. (g − f)x

Step-by-step explanation:  Subtract costs (f) from revenue (g) and multiply by bouquets made (x) to find profit.

Example would be if it costs $1 to make each bouquet and she charges $3 for each bouquet made.  If she made 5 and sold them it would be...

(g-f)x

(3 - 1) 5 = profit

(2) 5 = $10 profit

Answer:

Area of triangle = 8.9

Area of parallelogram = 53.4 yd² (option A)

Step-by-step explanation:

✔️Area of the triangle = ½*base*height

base = 3 m

height = 5.9 m

Area of triangle = ½*3*5.9

Area of triangle = 8.85 ≈ 8.9 (nearest tenth)

✔️Area of parallelogram = base*height

base = 8.9 yd

height = 6 yd

Area of parallelogram = 8.9*6 = 53.4 yd²

Answer:

2, 10, 0, 4

Step-by-step explanation:

"regrouping 1 tenth into 10 hundredths" is taking one of those green tenth sticks and dividing it into 10 hundredth squares. That means that you have 2 wholes, 2 tenths (remaining green sticks), and 10 hundredths (because the only hundredths you have are the ones you got from that tenth you regrouped).

After crossing them out, you have 2 wholes, 0 tenths (because you only had 2 before), and 4 hundredths (because you crossed out 6 of the 10, 10-6=4).

Hope I could help you!

Answer:

4

Step-by-step explanation:

5x + 10y = − 3.... (given)

Adding 7 on both sides,

5x + 10y + 7 = - 3 + 7

5x + 10y + 7 = 4

The circumference of the circle with a diameter of 40 is approximately 125.6636 units.

To calculate the circumference of a circle, we can use the formula:

Circumference = π * Diameter

Given that the diameter of the circle is 40, we can substitute this value into the formula:

Circumference = π * 40

The value of π (pi) is approximately 3.14159, so we can further simplify the equation:

Circumference ≈ 3.14159 * 40

Calculating this expression gives us:

Circumference ≈ 125.6636

Therefore, the circumference of the circle with a diameter of 40 is approximately 125.6636 units. Note that the unit of measurement is not provided in the question, so the answer is given in generic units.

James has dimes and quarters saved up in his change jar. He has a total of 162 coins totaling $31.20 what is the total amount james has in quarters?

a. $10.00

b. $6.20

c.$15.50

d.$25.00

Answer:

d.$25.00

Step-by-step explanation:

With the information provided, you can write the following equations given that dimes are equal to 0.10 and quarters to 0.25 to determine the number of dimes and quarters that James has:

x+y=162 (1)

0.10x+0.25y=31.20 (2), where:

x is the number of dimes

y is the number of quarters

First, you can solve for x in (1):

x=162-y (3)

Then, you have to replace (3) in (2) and solve for y:

0.10(162-y)+0.25y=31.20

16.2-0.10y+0.25y=31.20

0.15y=31.20-16.2

0.15y=15

y=15/0.15

y=100

Finally, you have to replace the value of y in (3) to find x:

x=162-100

x=62

Now, you know that James has 100 quarters and you can multiply this number for the value of a quarter to find the amount James has in quarters:

100*0.25=25

According to this, the answer is that James has $25 in quarters.

Answer:

I think the strawberry cake measure have to be 360⁰. so the arc measure is 360⁰÷3=100

so we have all three arcs congruent b/c all measures 100⁰

I think XYZ=100⁰

Step-by-step explanation:

solution given:

a strawberry cake is cut into three pieces

since

Arc measures of all three pieces are congruent

all 3 arc are equal

So it forms a equilateral TRIANGLE

each angle of equilateral triangle is 60°

So,measure of angle XYZ is 60°.

Answer:

Average time for West Middle was maximum.

Step-by-step explanation:

Average time for a track meet for schools = [tex]\frac{\text{Time}}{\text{Distance}}[/tex]

For Eastbay Middle,

Average time per mile = [tex]\frac{42}{7}[/tex]

                                     = 6 minutes per mile

For Northwest Middle,

Average time = [tex]\frac{25}{5}[/tex]

                       = 5 minutes per mile

For South Central Middle,

Average time = [tex]\frac{28}{4}[/tex]

                       = 7 minutes per mile

For West Middle,

Average time = [tex]\frac{48}{6}[/tex]

                       = 8 minutes per mile

Therefore, average time for West Middle (8 minutes per minute) was maximum.
