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)<span>Ed = 20</span>

Just multiply 4 by 25. You get 100.

Find the ordered pairs for the x- y-intercepts of the equation 4x+2y=16

erastovalidia [21]

The x-intercept is what 'x' is when 'y' is equal to 0. So plug in 0 for 'y' and solve for 'x':

$\sf 4x+2y=16$

$\sf 4x+2(0)=16$

Simplify:

$\sf 4x=16$

Divide 4 to both sides:

$\sf x=4$

So the x-intercept is (4, 0).

The y-intercept is what 'y' is when 'x' is equal to 0. So plug in 0 for 'x' and solve for 'y':

$\sf 4x+2y=16$

$\sf 4(0)+2y=16$

Simplify:

$\sf 2y=16$

Divide 2 to both sides:

$\sf y=8$

So the y-intercept is (0, 8).

There are 12 students in the pep squad.Three students are wearing white shirts.Six students are wearing blue shirts. What fracti

Viktor [21]

Answer:

$\frac{3}{4}$

Step-by-step explanation:

Total number of the students in the pep squad = 12 students

The number of the students wearing white shirts = 3 students

The number of the students wearing blue shirts = 6 students

Either white or blue shirts indicate that the students wearing white shirt or blue shirt.

Thus, number of students wearing either white or a blue shirt = 3 + 6 students = 9 students

So,

The fraction is:- $\frac{9}{12}=\frac{3}{4}$

if 1 mile is 5280 feet, and it is 2 miles from Ellie's house to the school, about how many feet is it from ellie's house to the

Bess [88]

This is a conversion problem. We know that 1 mile is 5280 feet, right? Since Ellie lives 2 miles, and two is double of 1, we just take 5280 and multiply that by two (or add it twice) to find how many feet is between Ellie's house and school. 5280 x 2 = 10560 (you get the same answer if you add 5280 twice). Therefore, 10560 feet lies between Ellie's house and school.
