Answer:

6 dogs

Step-by-step explanation:

To begin, we can start with that we know we want to work with two separate fractions. When we're doing this, we can make the denominators the same to make the comparisons easier.

Our two fractions are 1/8 and 3/4. To find a denominator that can work, we need to find the least common multiple. We can do this by listing the multiples of each number (in this case, the denominators) until one matches.

For 4, we have 4, 8, 12, 16, ...

For 8, we have 8, 16, 24, 32, ...

The lowest number in both of these is 8. Therefore, 8 is our least common multiple. Since 1/8 already has 8 as its denominator, we only need to change the denominator of 3/4.

To change the denominator, one way we can do this is to take (new denominator)/(old denominator) and multiply that value by both the numerator and denominator. We multiply that value by the numerator as well to ensure that the fraction stays the same.

We can then do (8/4) =2, so we multiply both 3 and 4 by 2 to get 6/8 = 3/4

Going back to our problem, we need to find how many dogs Dillon feeds with 6/8th of a can of food. Each dog takes 1/8th of a can of food every day, so we need to figure out how many times 1/8 goes into 6/8.

Because 1/8 is one-eighth of 8/8, or one whole, we can similarly say that 1/8 is one-sixth of 6/8, or six-eights. Therefore, Dillon has 6 dogs

Answer:

C (-2,0)

Step-by-step explanation:

Find the point where they intersect. It's (-2,0) on the graph

Answer:

C

Step-by-step explanation:

Looking at the graph, the solution is (-2, 0).

This is because on the x axis, the point is 2 units to left (negative number) and does not move on the y axis (leaving it at 0).

Another way to see this is by plugging in these coordinates into the system of equations:

0 = -2(-2) - 4

0 = 4 - 4

0 = 0

0 = -2 + 2

0 = 0

These are both correct, once again proving the solution is (-2, 0).

Answer:

x = 10

Step-by-step explanation:

8x-12 = 6x+ 8

or, 8x -6x = 8 + 12

or, 2x = 20

or, x = 20/2

so, x = 10

Answer:

10

there is a problem with the question...

IF it was : 8x - 12 = 6x + 8

then the answer would be: 2x = 20 .... x = 10

Answer:

61cm

Step-by-step explanation:

A right angled triangle is given to us with two sides as 11cm and 60 cm .We need to find out the length of the third side . Here , since it is a right angle triangle we can apply the Pythagoras theorem .

Pythagoras Theorem :- In a right angle triangle sum of squares of perpendicular and base is equal to the square of hypotenuse.

[tex]\rm\implies hypontenuse^2 = base^2+perpendicular^2[/tex]

As we can see that here ,

Base = 11cm

Perpendicular = 60cm.

[tex]\rm\implies Hypontenuse^2 = Perpendicular^2+Base^2 [/tex]

Substitute the respective values ,

[tex]\rm\implies h^2 = (11cm)^2+(60cm)^2 [/tex]

Simplifying ,

[tex]\rm\implies h^2 = 121cm^2+3600cm^2 [/tex]

Add the numbers on RHS ,

[tex]\rm\implies h^2= 3721 [/tex]

Take squareroot on both sides ,

[tex]\rm\implies h =\sqrt{61\times 61}[/tex]

Simplify the squareroot ,

[tex]\rm\implies \boxed{\blue{\rm Hypontenuse= 61 cm }}[/tex]

Hence the hypontenuse of the triangle is 61cm .

Answer:

8 1/4 kg

Step-by-step explanation:

Add the weight of the fruits together

3 1/2 + 4 3/4

Get a common denominator of 4

3 2/4 + 4 3/4

7 5/4

7 4/4 + 1/4

8 1/4 kg

You have the right idea. You'll apply a y-axis reflection to go from above the x axis to below it. This allows us to move the red line into the correct vertical position without having to use a vertical translation.

Afterward, you'll shift the red line 4 units to the right to have it line up perfectly with the blue line.

Going from f(x) to -f(x) is the y-axis reflection part

Going from -f(x) to -f(x-4) will shift the line 4 units to the right.

Answer:

 He Saved 18.664%

Step-by-step explanation:

Well first we need to find the total of the original price of the items he got

then we can solve for how much (in percentage) he saved

We know the original price of the pant as € 34.50 because 5+29.50=34.50

Now lets find out the original price of the shirt

The shirt's original price can be found by using this equation

x * .75 = 17

17/ .75  = x

22.67 = x

Now since we know the prices of these two items lets add them together

34.50 + 22.67 = 57.17

He actually spent

29.50 + 17 = 46.5

Now what percentage of 57.17 is 46.5?

We can use 46.5/57.17 = 0.81336

.81336 *100 =  81.336%

100-81.336 = 18.664

18.664% was saved

Answer:

See answers below

Step-by-step explanation:

For the expression

The sum of two numbers is  25.  The first number is 37 more  than 2 times the second  number

Let the two numbers be x and y

If the sum is 25, then;

x + y = 25 .... 1

37 more  than 2 times the second  the number is expressed as;

37+2y

If the first number is 37 more  than 2 times the second  number, then;

x = 37 + 2y

x - 2y = 37 ...2

This shows that the simultaneous equation that fits the expressions are;

x - 2y = 37

x + y = 25

For the expression

A child has a piggy bank full  of $1 and $2 coins totaling  $37.  There are 25 more $1 coins  than there are $2 coins.

Let x be the $1 coins

Let y be the $2 coins

If a child has a piggy bank full  of $1 and $2 coins totaling  $37, then;

x + 2y = 37 ... 1

Also, if there are 25 more $1 coins  than there are $2 coins, then;

x = 25 + y

x - y = 25 ...2

The equivalent expressions for the statement will be;

x + 2y = 37

x - y = 25

This hence leaves us with the last;

An exam that is worth 37  marks contain 25  questions.  The questions are either  worth 1 mark or 2 marks. The resulting simultaneous equation will be;

x + 2y = 37

x + y = 25

Answer:

5 + 20 + 6

Step-by-step explanation:

that's how you get

Answer:

x = 69

Step-by-step explanation:

since AB is parallel to CD we can find the value of y with the following equation :

2y - 40 = 66 add 40 to both sides

2y = 110 divide both sides by 2

y = 55

from supplementary angles, we know that the exterior angle's measure is 124

since the sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle

y + x = 124 we found value of y earlier

55 + x = 124 subtract 55 from both sides

x = 69

Answer:

648

Step-by-step explanation:

18√2×18√2= (18√2)²

                  = (18)²×(√2)²

                  = 324×2

                  = 648

Answer:

Step-by-step explanation:

for question 5 )  

we know that  x-5 = 6   because I'm pretty sure outside of the question we are told that the rectangles  are similar and therefore,  we can say the above

x-5 = 6

add 5 to both side

x = 11

for question 6)

30 is  [tex]\frac{5}{6}[/tex] of 36, so use that on the remaining given side

 [tex]\frac{5}{6}[/tex] * 15 = 12.5

then thats what the other side of the bigger shape is

12.5 = x + 6

minus 6 from both sides

6.5 = x

by the way,  notice that they have used a variable "x" for both 5 & 6 which is named the same but has a different value  in each problem.  X is the name of the variable for each problem, but doesn't have any meaning once outside of each of the problems.  It's just confusing to use the same named variable at times.  something like xy   and xz ,  might have been better names.    anyway  :)

Answer:

The answer is 0.6*7=4.2ounces of fish food.

Step-by-step explanation:

If 0.6 ounces of fish food will suffice for Dominic's fish for a month, then for 7 months he would need 7 times the food he requires for 1 month.

7*0.6=4.2 ounces of fish food.
