Example:17 and −34 are rational numbers

Answer:

y-(-8) = 7(x-3) or

y+8 = 7(x-3)

Answer:

x=5

Step-by-step explanation:

Answer:

the answer is x=5                              

Answer:

x+y >= 5

y<=8

x<=10

x>y

Step-by-step explanation:

x+y is greater or equal to 5 because you need at least 5 for dinner.

y is less than equal to 8 because the fishing laws state you can't have more than 8 trout.

x is less than equal to 10 because the fishing laws state you can't have more than 10 salmon.

x>y because you intend to catch more salmon than trout

Answer:

Total number of students = 4x

Step-by-step explanation:

Let the number of boys be x

Since, no of girls = 3 times the no of boys

So, number of girls = 3x

Total number of students = no of boys + no of girls

Total number of students = x + 3x

Total number of students = 4x

Answer:

The total number of students is 4x

Step-by-step explanation:

Answer:

y=1x+4 is the answer :))))

Answer:

y = x + 4

Step-by-step explanation:

slope intercept equation: y = mx + b

m = slope

b = y-intercept(when x =0)

use the points given; (0,4) and m = 1

to find b

y = mx + b

4 = 1(0) + b

4 = b

now put your equation together.

y = 1x + 4

or y = x + 4

Answer:

$73.77

I'm not sure if I understood the question correctly

explain it in the comments

Step-by-step explanation:

If what I think the question is asking is correct, theres a 70% sale on the full price which is $245.89

70% of 245.89 is 172.123, so now you subtract the sale(172.123) from the original price(245.89)

245.89 - 172.123 = 73.767

If the question was asking a different thing explain it in the comments and I'll answer it for you

Answer:

4cm by 4cm

Step-by-step explanation:

x+3+x+3+x+3+x+3=40

4x+12=40

4x=40-12

4x=28

x=28/4

x=7

original dimension=7-3

=4cm

The required original dimension of the square is 7.

Given that,

If the length of a side of a square is increased by 3 cm, the perimeter of the new square is 40 cm more than twice the length of a side of the original square. To determine the dimensions of the original square.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the length of the square be x,
Now,
According to the question,
The perimeter of the square = 40
4 (x + 3) = 40
x + 3 = 10
x = 7

Thus, the required dimension of the square is 7.

Answer:

The probability of picking a nickel or a dime is 25%

Step-by-step explanation:

Since we have the same amount of nickels and dimes we can cancel them out. That would make it a 50% chance to get one or the other, or, a 1&1 chance, but since there is 8 coins all together there is a chance to pull out 2 nickels or 2 dimes. 4 possibilities.

1. 1 nickel 1 dime

2. 2 dimes

3. 2 nickels

4. 1 dime 1 nickel

4 x 25% = 100%

each possibility has a 25% chance to happen

Answer:

x = 79°

y = 22°

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180°

79° + x° + y° = 180° the given triangular shape is isosceles which means x = 79°

so 79° + 79° + y° = 180° add like terms

158° + y° = 180° subtract 158 from both sides

y° = 22°

Answer:

x=79

y=22

Step-by-step explanation:

its an isosceles triangle meaning that 2 sides are the same and if 2 sides are the same 2 angles are and that means that 79 would have to equal x because that is the one side and then you add the two 79s to get 158 and subtract that minus 180 to get 22 leaving that to be y

79+79=158

180-158=22

y=22

Answer:

15 inches

Step-by-step explanation:

Here, we have a scale of 5 inches to 3 miles

We have 9 miles here, we now want to get the amount of corresponding inches

Let the corresponding inches be x

5 inches to 3 miles

x inches to 9 miles

That means ;

x * 3 = 5.* 9

x = 45/3

x = 15 inches
