Answer:
x+ (x+1) = 55
27, 28
Step-by-step explanation:
Let x = first number
x+1 is the next consecutive number
x+ (x+1) = 55
Combine like terms
2x+1 = 55
Subtract 1 from each side
2x+1-1 = 55-1
2x = 54
Divide by 2
2x/2 = 54/2
x = 27
The numbers are 27 and 28
An irrational number is a non terminating, non repeating number. Therefore, square root of 5 is an irrational number.
Y= 1/2x - 1.
the slope is 1/2 and the y-intercept is -1
Answer:
449 per hour
Step-by-step explanation:
First of all we know the question is asking us to round to the nearest tenth and find the rate of gallons per hour.
First:
Know there are 60 minutes in one hour
Second:
Take 7.48 and multiply it by 60
Third:
This should give you---448.8
Which is correct, but we are not done
Fourth:
Round to the nearest whole number
448.8
8 is closer to 10 than it is to 1 so we add 0.2
Which gives us 449
Five:
Just add the "per hour"
Six:
Your answer is---449 per hour---
To determine if the ordered pair (3 , -2) is a solution to 4x = 3y + 18,
plug in the point into the equation.
4x = 3y + 18 (Plug in 3 for "x", and plug in -2 for "y")
4(3) = 3(-2) + 18
12 = -6 + 18
12 = 12
This is a solution because in the end, the number is the same on both sides
