Answer:

Next numbers: 3430, 24010

Step-by-step explanation:

AS you can see you just need to discover the pattern by dividing the subsequent numbers by the direct number before that:

490/70=7

70/10=7

So both numbers indicate the patter on multiply by 7.

So to calculate the next number we first have to multiply 490*7= 3430

Now we just have to multiply the 3430 by 7 and that would be 24010.

So the next numbers would be 3430 and 24010,

Each of the numbers 10, 70 and 490 is separated from the next by a factor of 7.  10 times 7 is 70; 70 times 7 is 490; 7 times 490 is what?  7 times 7 times 490 is what?

A+b=77,a-b=13 care sun nr
STALIN [3.7K]
It's a simultaneous equation:
Steps:
1.Number the equations..

a+b=77 -1
a-b=13 -2

2. Choose what variable you want to use. In this case I would use the "b". Since the signs in front of the "b's" are different, add the two equations together

a + b = 77
+ + +
a (-b) = 13

Which gives;
2a = 90

Then solve to find a:
2a=90
a= 90/2
a=45

3.Then plug the "a" value into any of the original equations to find the "b" value. I would use equation 1 since the all the variables are positive.

a + b = 77
(45) + b = 77
b=77-45
b=32

4.Solution

a=45
b=32

a piece of string is 3 yards long. How many 1 and a quarter yard long pieces can Julie cut from the string?
Georgia [21]
This question is actually a lot simpler than it seems

for a quarter think about money - a quarter is 25 cents or 1/4 of a dollar - so 1 and a quarter yard in decimal form is equivalent to 1.25

now you need to find how many 1 and a quarter yards are in 3 yards - to do this you simply divide 3 by 1.25

3/1.25 = 2.4

so julie can cut 2.4 1 and a quarter long pieces from the string

if you have any questions about how i answered this question please let me know:)
