Schach [20]3 years ago

3 0

For the first one, 1 1/2 + 1 1/2 = 3

To find this out, take what we know, the 1 1/2 and subtract that from the final answer, 3.
That leaves us with the missing number.

Same with the rest of them, subtract the number that is know from the total.

#3 is 2 1/2
#4 is 1/4
#5 is 1 1/4

Hope this helps!

What are the three differences between an inconsistent system and a consistent and independent system. Explan?

RUDIKE [14]

Hey there Mejia021274,
1) Independent systems have exactly one solution:
x + y = 1
x - y = 3
x = 2, y = -1

2) Inconsistent systems have no solutions :
5x + y = 6
5x + y = 10
There is no solution as 5x + y cannot be equal to 6 and 10

3) Consistent systems have a lot of solutions:
x+y = 5
2x+2y = 10 
A few solutions to this system are (1,4), (2,3), (3,2), (4,1), (5,0), and so on.

Hope this helps :))

Mark made a scale drawing of a soccer field, using a scale of .5 cm=1m. The actual length of the field is 110 m. What is the len

VikaD [51]

Answer:

The length of the field on the drawing is 55 cm that is option D.

Step-by-step explanation:

Given:

Mark made a scale drawing of a soccer field, using a scale of .5 cm=1 m.

The actual length of the field is 110 m.

Now, to find the length of the field on the drawing.

Let the length of the field on drawing be $x\ cm.$

As given,

Drawing of a soccer field, using a scale of 0.5 cm=1 m.

So, 0.5 cm is equivalent to 1 m.

Thus, $x\ cm$ is equivalent to 110 m.

Now, to get the length of the field on the drawing by using cross multiplication:

$\frac{0.5}{1} =\frac{x}{110}$

By cross multiplying we get:

$55=x$

$x=55\ cm$

Therefore, the length of the field on the drawing is 55 cm that is option D.

two classmates have decided to read all the volumes in a popular series of books. Katie has already read 4 volumes and will cont

scoray [572]

To solve this we can make it into an equation, which looks like this

y = 2x (for Rebecca)
y = x + 10 (for Alice)

The we subtract one equation from the other to solve

0 = x - 10
10 = x
x = 10

Now we replace x in whichever equation and we get 20

So, each girl will read 20 books for them to be at the same book.

Hope this helps, remember that Jesus loves you
