pls help me with this if you can
1) Let L = the larger # and S = the smaller #.
A large # is 5 more than twice a smaller #.....This gives Eq 1) L = 5 + 2S
Their sum is 80...This gives Eq 2) L + S = 80.
Substitute Eq 1) into Eq 2), you get
L + S = 80
5 + 2S + S = 80
3S = 75
S = 75 / 3 = 25
L = 5 + 2S
= 5 + 2(25)
= 5 + 50
= 55

· Interval
A set of values between two endpoints.
· Inequality
A mathematical expression which shows that two quantites are not equal.
Answer:
1) x = 25
2) 2(25)+5 = 55
-12<= x < 6
x <2 and x <= -7
Step-by-step explanation:
1) x
2) 2x + 5
x + 2x + 5 = 80
3x = 80 - 5
x = 75/3
x = 25
-24 <= 2x - 10
-24+10 <= 2x
-14/2 <= x
-7 <= x
2x -10< -6
2x < - 6 + 10
x < 4/2
x < 2
-½(x + 1¼) = - 3 + ¼x
Solve for x

Translate the sentence into an equation or formula.
The perimeter P of a triangle is equal to the sum of the lengths of sides a, b, and c.
Answer:
P = a + b + c
Step-by-step explanation:
Find three consecutive integers such that twice the first is equal to 17 more than the largest number
smallest is X
middle is X+1
largest is X+2
2X = x+2 + 17
2X = x + 19
x = 19

Write a story that would explain the graph below.
Answer:
A kid leaping happily to home after school
The graph represents the relationship between height and time.
Given that,
A curve has been shown we have to explain the behavior of the curve.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
The curve is shown, where the vertical axis represents the height above the ground and the horizontal axis represents the time. Let's assume a plane of paper is flying, the plane getting a rise and then a certain down and again rise and down as according to the height of the plane.
Thus, the graph represents the relationship between height and time.

Place the following steps in order to describe how to solve the following equation: 2(2x+3)-2=5
Answer:
0.25
Step-by-step explanation:
First, you distribute the equation.
2(2x+3)-2=5
4x+6-2=5
Then, you combine like terms.
4x+6-2=5
4x+4=5
Next, you subtract 4 from each side.
4x+4=5
4x+4-4=4x
5-4=1
4x=1
Finally, you divide each side by 4.
4x/4
1/4
(4x/4 you'd end up with x)
Answer: x=1/4

Answer:
n = 27
Step-by-step explanation:
Multiplication has the commutative property, which means it doesn't matter what way around you put the numbers e.g. 4 × 3 = 3 × 4
So 27π = 27 × π = π × 27
n is 27
