Answer:

5,240 literate

1310 illiterate

Step-by-step explanation:

-ratio of literate : illiterate is 1:4

-add the numbers in the ratio (4+1=5)

-divide total population by 5 (6,550/5= 1,310)

-multiply the outcome by 4 to find the number of literate people (1,310*4=5,240 people)

-subtract the number of literate people from total population to find number of illiterate people (6,550-5,240= 1,310 people).

Answer:

The solution of the given equations is (-3,2)

Step-by-step explanation:

The Given equations are 2 x+3 y=0 .......(1)

x+2 y-1 =0.........(2)

Solving<u> </u>both equations by using substitution method

multiply equation (2) with number '2' ,

2 x+4 y-2=0.......(3)

subtracting the equations (1) and (3) and cancelled 'x' terms

we get $3y-4y=0-2$

$y=2$

<u>Step 3:</u>-

substitute y= 2 in equation (1) we get

$2 x+3 y=0$

$2 x+3(2)=0$

$2 x=-6$

$x=-3$

<u>Final answer</u>:-

The solution of the given equations is (-3,2)

Cheryl falkowski has a collection of silver spoons from all over the world. she finds that she can arrange her spoons in sets of

Afina-wow [57]

There are a number of ways to approach this problem, including writing all the numbers that match one of the arrangements, such as for sets of 15:
.. 14, 29, 44, 59, 74, 89, 104, 119, 134, 149, 164, 179, 194 (separated by 15)
Modulo 8, these numbers are
.. 6, 5, 4, 3, 2, 1, 0, 7, 6, 5, 4, 3, 2
This reduces the numbers of interest to those that are 3 modulo 8:
.. 59, 179 (separated by 8*15 = 120)
Looking at these modulo 7, we have
.. 3, 4
pinpointing 179 as the number of spoons in Cheryl's collection.

_____
The attachment shows a solution via graphing calculator. We simply added the absolute values of the differences of the remainders from the desired values and looked for where that sum was zero. This method, too, pointed to 179 as the solution to the problem.
