Answer:

2/3x + 3y = 1/5

Step-by-step explanation:

-3y + 1/5 = 2/3x (subtract 1/5)

-3y = 2/3x - 1/5 (subtract 2/3x)

-2/3x - 3y = -1/5 (divide by negative 1)

2/3x + 3y = 1/5

Hope this helps ya!!

Answer:

y=5 x=3

Step-by-step explanation:

x-y=-2 move the y over to isolate x

x=-2+y Now plug that in for x in the first equation

2(-2+y)-y=1 Distribute

-4+y=1 Add 4 on both sides

y=5

x-5=-2

x=3

Answer:-1

Step-by-step explanation:

the output of a function is the y value while the input is the x value.

so the question is asking what does the y value( output) have to be for the x value( input) to be zero.

since the graph is provided we can just look to see where the x values becomes zero ( the y axis is when all y values are zero)

we then can identify that the y intercept is -1

Answer:

15/8

Step-by-step explanation:

The area of a rectangle is given as 5/6 square foot.

The width is given as 2/3 foot

But area if a Rectangle = Lenght × width

A = Lenght x width

5/6= Lenght × 2/3

If we make Lenght subject of the formula we have

lenght= (5/6) / (2/3)

length = (5×3)/(6×2)

Lenght= 5/4

To calculate the number of times greater is the length than the width we take the ratio of Lenght and width

Lenght / width = (5/4) / (2/3)

= (5×3)/(4×2)

= 15/8

Hence the number of times greater is the length than the width is 15/8

Answer:

There are 4 toppings on a pizza that costs $15.

Step-by-step explanation:

To find the amount of toppings that are on a pizza that costs $15, you will need to consider that P=15, replace this value on the formula and then, solve for n that is the number of toppings on the pizza:

P=2n+7

15=2n+7

15-7=2n

n=8/2

n=4

According to this, the answer is that there are 4 toppings on a pizza that costs $15.

Answer:

There are 30 girls

Step-by-step explanation:

The ratio is 3:5 so (3)*(6)= 18 boys , and (5)*(6)=30

30+18=48 members

There were 30 girls in swim team.

We have,

Total Members = 48

Ratio of Boys to Girls= 3:5

So, the number of boys are

= 3/8 x 48

= 3 x 6

= 18

and, the number of girls

= 5/8 x 48

= 5 x 6

= 30

Thus, 30 girls were in swim team.

Answer:

Step-by-step explanation:

This problem is on the mensuration of flat shapes, a circle.

The length of the string corresponds to the circumference of the circle.

The lenght of the string can be calculated by using the expression for circumference, if after using the ruler to obtain the diameter "d"

upon measuring the diameter we can further obtain the radius "r"

The expression for the radius is r=d/2 (the radius is half the diameter)

C=2πr

where pi= 3.124 a constant term

Hence Circumference is the same as the length of the string

Answer:

36,42,102

Step-by-step explanation:

A triangle is 180° total so your equation to find x is:

3x+6+4x+2+10x+2=180°

17x+10=180

17x=170

x=10

to find the individual sides:

3(10)+6=36

4(10)+2=42

10(10)+2=102

to make sure this is right, add 36+42+102. It should equal 180 and it does

The fraction equivalent of 13/14% is 13/1400.

If the numerator is bigger, it is referred to as an improper fraction and can also be expressed as a mixed number, which is a whole-number quotient with a proper-fraction remainder.

Any fraction can be expressed in decimal form by dividing it by its denominator. One or more digits may continue to repeat indefinitely or the result may come to a stop at some point.

So as per the question, the fraction equivalent of the given number will be

13/14% i.e 13/1400.

Now we have a rational number with us, the equivalent fraction can be obtained by multiplying similar numbers in both the numerator and denominator.

so if we multiply by 2 on both sides the fraction we get will be 26/2800.

so if we multiply by 10 on both sides the fraction we get will be 130/14000.

Hence we will get an infinite number of fractions equivalent to 13/14%.

Answer:

1/4 equal pieces

Step-by-step explanation:

Total number of bowls of rice = 3

We are seeking servings of size 12

Then it means we are dividing 3bowls into 12 equal pieces

= 3/12 bowls

= 1/4 equal pieces

Which means each member of the family is getting 1/4 each of the bowl of rice

Therefore, 1/4 servings of size 12 can you make out of the 3 bowls of rice

Answer:

The equation for the nth term will be;

An = 10 + 2n

After the 9th planter ( 8 more than the initial one); number of trees will be 28

Step-by-step explanation:

After the first person plant two trees, there were 12 trees at the plant sites

What this mean is that initially, they were 12-2 = 10 trees at the plant site

The nth term of the sequence which represents the number of trees given the number of persons that have planted will be;

An = 10 + 2n

Now, after 8 more people planted, since we had one that already planted, the total number of planters is now 9 planters

So using the equation, n will be 9

So ; A9 = 10 + 2(9)

A9 = 10 + 18

A9 = 28
