2 consecutive numbers that add up to 719
Answers
Answer:
359+360
Step-by-step explanation:
Answer:
359+360
Step-by-step explanation:
Here we will use algebra to find three consecutive integers whose sum is 719. We start by assigning X to the first integer. Since they are consecutive, it means that the 2nd number will be X + 1 and the 3rd number will be X + 2 and they should all add up to 719. Therefore, you can write the equation as follows:
(X) + (X + 1) + (X + 2) = 719

Hey guys this is confusing, someone plz help
Answers
Answer: x = 13
Step-by-step explanation:
To find the value of x, you have to find ∠QRP
∠QRP + ∠QRS = 180
∠QRP + 95 = 180
Subtract 95 from both sides
∠QRP = 85
∠RQP + ∠QPR + ∠QRP = 180 Definition of triangle
(4x + 3) + (3x + 1) + 85 = 180
Subtract 85 from both sides
(4x + 3) + (3x + 1) = 95
7x + 4 = 95
Subtract 4 from both sides
7x = 91
Divide 7 from both sides
x = 13

A robin can fly 10 miles per hour faster than a blue jay. It takes a robin 1 1/2 hours to fly 45 miles.
How many hours will it take a blue jay to fly that same distance?
Answers
Answer: [tex]2\dfrac14\text{ hours}[/tex]
Step-by-step explanation:
Given: It takes a robin [tex]1\dfrac12[/tex] hours to fly 45 miles.
[tex]1\dfrac12=\dfrac32[/tex]
Speed of robin= [tex]\dfrac{distance}{time}=\dfrac{45}{\dfrac32}[/tex]
[tex]\dfrac{45}{3}\times2= 15\times2= 30\text{ miles per hour}[/tex]
A robin can fly 10 miles per hour faster than a blue jay. It
Speed of Blue jay = Speed of robin - 10 miles per hour
= 30 miles per hour - 10 miles per hour
= 20 miles per hour
Time taken to cover 45 miles = [tex]\dfrac{45}{20}=\dfrac{9}{4}=2\dfrac14\text{ hours}[/tex]
Hence, it will take [tex]2\dfrac14\text{ hours}[/tex] by a blue jay to fly that same distance.
