Which ordered pair is a solution to the system of equations 4x-y=10 y=2x-2

Answers

Answer 1
Answer:

Answer:

single solution : (4 ; 6)

Step-by-step explanation:

hello :

4x-y=10.....(1)

y=2x-2.....(2)

put the value for y in (1) :

4x-(2x-2)=10

4x-2x +2 = 10

2x=8

x=8/2 =4

but : y = 2x-2

so : y =2(4)-2=6

single solution : (4 ; 6)

One third of a number t is equal to 7

Answers

Answer:

The value of t is 21

Step-by-step explanation:

Given :One third of a number t is equal to 7

To Find : Find the value of t

Solution :

Number = t

One third of a number = (t)/(3)

Now we are given that One third of a number t is equal to 7

So, (t)/(3)=7

t=7 * 3

t=21

Hence the number is 21
if one third of t is 7 than t is equal to 21

A town in east Texas recieved 10 inches of rain in two weeks. If it kept raining at this rate for a 31-day month, how much rain did the town recieve?

Answers

The best way to approach this problem is to find out how much fell in week. As you know what two weeks is, you simply have to halve this, giving you that one week is 5 inches of rain. One you have this, you can multiply this by 4 (as this will give you 4 weeks, or 28 days), and this gives you 20 inches in 28 days. You should then find the odd three days. If you divide 5 by 7, this will give you the rain fall in one day. 5/7= 0.8 inches per day. You then have top multiply this by 3 (as you've got three odd days), and this gives you 2.4. You then have to add together 2.4 and 20, giving you 22.4
Therefore, if the rain continued to fall at the same rate for 31 days, it would receive 22.4 inches of rain.
Hope this helps :) 

Answer:

22.4
