What number is 4 times as many as 25

2 answers:

6 0

This is a standard relationship/systems of equations question. Here is how you attack it. Firstly, set up equations to represent the relationships. Ed = 4*Kim That shows that Ed has four times as many pins as Kim. Next, we see that the two have 25 together. So: Ed + Kim = 25 Now we have our two equations. In order to solve, we need to get one of the equations down to one variable. We can achieve this via substitution. The first equation tells us that we can substitute 4*Kim for Ed (in the second equation). So, let's do just that: 4*Kim + Kim = 255*Kim = 25Kim = 5 Using the first equation again, we can solve for Ed: Ed = 4*KimEd = 4*(5)Ed = 20

Just multiply 4 by 25. You get 100.

Answer: 34 panthers 13 Giants

Step-by-step explanation: 47 - 13= 34 which will equal the panthers now find what number with 34 would equal 47. so that means, 34+13= 47

Write the coordinate of the intercept

Basile [38]

Answer:

m = 2/3

y-intercept: 2

Explanation:

First convert this equation into standard form by distributing the 6y and -4x from the coefficient of 2, and then putting the variables in order.

This equation should be in the form: Ax + By = C (Standard form)

y = -Ax/B + C/B : y = mx + b (Slope intercept form)

2(6y - 4x) = 24 → 12y - 8x = 24

→ -8x + 12y = 24 → -8x = -12y + 24 → 8x = 12y - 24 → 8x - 12y = -24

8x - 12y = -24

A B C

Once you have standard form, you are ready to convert this into slope intercept by isolating the y completely.

8x - 12y = -24

-8x -8x

(First through the subtraction property of equality, remove 8x from both sides so that -12y is by itself on the left)

-12y = -8x - 24

×-1 ×-1 ×-1

(Through the identity property of negative 1, remove the negative sign from all of the numbers because a negative times a negative is a positive)

12y = 8x + 24

(Lastly, through the division property of equality, divide all sides by 12 because it is the coefficient of y, which will solve for the variable)

Identify the number of solutions to the following system:

zalisa [80]

Answer:

Step-by-step explanation:

Since these lines have the same slope and different y-intercepts, they are parallel lines. As such lines do not intersect, we can say that :

The system has no solutions.

You plan to construct a brick wall measuring 14.5 ft. in length, 5.5 ft. high, and 0.5 ft. in width. If a brick measures 6 in. x

Licemer1 [7]

Answer: There are 1436 bricks that he will need to make a brick wall.

Step-by-step explanation:

Since we have given that

Dimensions of a brick wall is given by

Length = 14.5 feet

Width = 0.5 feet

Height = 5.5 feet

Dimensions of a brick is given by

Length = 6 inch

Width = 4 inch

Height = 2 inch

We need to find the number of bricks :

So, Number of bricks is given by

$\text{ Number of bricks }=\frac{\text{ Volume of brick wall }}{\text{ Volume of brick}}\\\\=\frac{14.5\times 5.5\times 0.5\times 12\times 12\times 12}{6\times 4\times 2}\\\\=1435.5\\\\=1436$

Hence, there are 1436 bricks that he will need to make a brick wall.
