Answer:

20/35 =4/7 it is the simplest form of 20:35

Answer:

5 times

Step-by-step explanation:

Given

[tex]D = 30.5kg[/tex] -- Dinorah's weight

[tex]d = 6.1kg[/tex] --- Her dog's weight

Required

Determine how much she weighs as much as her dog

To do this, we simply divide her weight by her dogs.

[tex]n = \frac{D}{d}[/tex]

[tex]n = \frac{30.5kg}{6.1kg}[/tex]

[tex]n = \frac{30.5}{6.1}[/tex]

[tex]n = 5[/tex]

Answer:

x = -18

y = 4

Step-by-step explanation:

x + y = 4

2x + 3y = 30

You can do any math operation to each side of the equal sign as long as you do the same operation to both sides.

change x + y = 4       to        x = 4 - y  

Now substitute (4 - y) into the second equation, in place of x.

2(4-y) + 3y = 30

multiply the 2(4-y) part:

8 -2y + 3y = 30

simplify:

8 + y = 30

subtract 8 from each side:

y = 22

now substitute the value of y back into the first equation to solve for x:

x + 22 = 4

subtract 22 from both sides:

x = -18

Check:

x + y = 4

22 -18 = 4  

4 = 4       (this checks)

2(-18) + 3(22) = 30

-36 + 66 = 30

30 =30     (this checks also)

PS: you could have solved for y first if you had wanted to. The results would be the same.

Answer:

the questions mark is 2

9-7 = 2

Answer:

12^2-(9-7)^3+6

we make 9-7=2

then 12^2-(2)^3+6

Answer:

6

Step-by-step explanation:

i just cubed all of the numbers given and gotten that 6^3=216

Answer:

x=6

Step-by-step explanation:

If you would like to know the value of x, you can calculate this using the following steps:

x^3 = 216

x = sqrt3(216)

x = 6

The correct result would be 6.

Answer:

always acute angle.as each angle is 60°

Answer:

the absolute value is always the same number positive so the answer would just be 4

Answer:

n< 40

Step-by-step explanation:

The greatest number of bags she can make without having any stickers or pencils left over is 18 bags.

Step-by-step explanation:

The best way to go about this is by dividing the total number of pencils and stickers by the answer choices given and starting with the highest number (27). We already know that 27 goes into 54 twice without anything left over, but can only go into 36 once while having 9 leftover. This would eliminate 27 as an answer choice as it does not meet the criteria.

Repeat the same process with 18, so 54 divided by 18 is 3, and 36 divided by 18 is 2. There is nothing left over, every bag will have an equal number of pencils and stickers. With this answer, the question criteria is true, making this the correct answer choice.

Answer:

3

Step-by-step explanation:

4 ^2+x^2=5^2

5^2-4^2=9

square root of 9=3

Answer:

I think the answer is 180.00 i may be wrong i hope this helps

Step-by-step explanation:

Answer:

Step-by-step explanation:

(X + 3) ( x + 3) is x^2 + 3x + 9

-1 is now 8

X^2 + 3x + 8 = 35

Subtract 8 from both sides so it now equals 27

Divide everything by 3 so its now

X^2 + x = 9 use quadratic formula and get x = -3.541 and 2.541

Answer:

B. 62mph

B. 55weeks

Step-by-step explanation:

496 ÷ 8 = 62

15weeks/3houses = x weeks/11houses

15 × 11 ÷ 3 =55weeks

good luck, i hope this helps :)

Answer:

-15

Step-by-step explanation: the only numbers that can be used under a 0 is negative and since its colder it goes down -15+0 is -15

Answer:

Step-by-step explanation:

The midpoint between two points is the average of the coordinates.

mp=((x2+x1)/2, (y2+y1)/2)

In this case we are given one end point and the midpoint.

Just look at the x coordinate first.

If the mid x is 8 and the x from j is 10 we have

(10+x)/2=8

10+x=16

x=6, now for the y for j when y=6 and mid y of 5

(6+y)/2=5

6+y=10

y=4

So the coordinates of K are (6,4)

Answer:

This should be -5

Step-by-step explanation:

The function is f of x

Substitute 0 for x

the equations hould now be

f(0) = (0 + 5)(0 - 1)

Combine like terms: f(0) = (5)(-1)

Multiply 5 and -1 to get -5

Answer: 0-
