Carlos bought 80 feet of rope for $17.60. He needs 20 more feet. If the unit price is the same how much will he pay for the extra 20 feet of rope? Show each step of your solution and explain your reasoning.
Answer:
$4.40
Step-by-step explanation:
ok so this is an instance of proportional relationships, in this case we changed one side of this equation, and now we need to figure out how to change the other side the that the change is made on both sides of the (=)
heres what we know
$17.60 = 80ft.
$??.?? = 20ft.
to help us find the change we can divide the first known side with second known side as shown below
80 / 20 = 4
so now we know that 80 was divided by 4 to get 20, so now we can divide the other side by the same amount to get...
$17.60 / 4 = $4.40
so it costs $4.40 for 20 ft. of rope
EXTRA: just because we can, lets figure out what 1 ft of rope costs using the same method as show above (starting with 20 ft)
20 / 1 = 20
$4.40 / 20 = $0.22
so the rate at wich the rope is sold is 22 cents a foot

Step-by-step explanation:
In the first problem, you have to do -5x + -8x which is -13x. Then you add 2+9 which is 11. You will get the expression -13x + 11.
In the second problem, you have to do 5x + 3x which is 8x. Then you add 8 + 2 which is 10. You will get the expression 8x + 10.
In the third problem, you have to do 1x + 9x which is 10x. The. you add 4 + 4 which is 8. You will get the expression 10x + 8.
In the fourth problem, you have to do -7x + -2x which is -9x. The. you add 6 + 9 which is 15. You will get the expression -9x + 15.
In the last problem, you have to do -4x -1x which is -5x. The. you add 14 + 3 which is 17. You will get the expression -5x + 17.

Evaluate the expression y2 when y=2.5
Answer:
5
Step-by-step explanation:
if u wouldnt mind giving me brainliest, just tryna rank up
The value of the expression at y = 2.5 is 6.25.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
y²
Substitute y = 2.5
= y²
= 2.5²
= 2.5 x 2.5
= 6.25
Thus,
The value is 6.25.

Answer:
y = -90x + 2000
Step-by-step explanation:
Hello There!
So we need to write an equation of the line in slope-intercept form
y = mx + b
where m = slope and b = y intercept
They give us everything in the caption
They say that a hot air balloon descends from 2000 feet at a constant rate of 90 feet per minute
Descends from 2000 feet indicates that the hot air balloon starts at 2000 feet
Thus this is the y intercept
Descends indicates that the slope is going to be negative because descend means to go down
The hot air balloon descends at a constant rate of 90 feet per minute
Thus meaning that the slope is -90
Now that we have everything we add it all together and get that the equation is
y = -90x + 2000
hope this helps :)
Answer:
y = -90x + 2000
Step-by-step explanation:
in y = mx+b, m is the slope and b is the y intercept
Therefore the y intercept is 2000
Now we have y = mx + 2000
Because the balloon descends at 90 ft/min, the m value is -90
So the answer is y = -90x + 2000
Select the two expressions that are equivalent to 4 + w + 12w.
a
4 + 13w
b
13w2 + 4
c
2(2 + 6w) + w
d
16 + 2w
e
2(2 + 6w2)
The equivalent values of the expression A = 4 + w + 12w are B = 4 + 13w and C = 2 ( 2 + 6w ) + w
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
To find the expressions that are equivalent to 4 + w + 12w, we need to simplify the expression and see which of the given expressions have the same result.
4 + w + 12w = 4 + 13w
So, the equivalent expressions are (a) 4 + 13w and (c) 2(2 + 6w) + w.
Let's check the other options:
(b) 13w² + 4: This is not equivalent, as it involves squaring the w term.
(d) 16 + 2w: This is not equivalent, as it involves adding a constant term.
(e) 2(2 + 6w²): This is not equivalent, as it involves squaring the 6w term.
Hence , the two expressions that are equivalent to 4 + w + 12w are (a) 4 + 13w and (c) 2(2 + 6w) + w.

Over the course of a year, a classroom went from 15 students to 19 students.
Use the drop-down menus to build an equation that could be used to find the percent change, p, in the number of students.
Answer:
26.7%
Step-by-step explanation:
The positive change from 15 to 19 is 4.
Find the value of the fraction 4/15 and multiply the result by 100% to obtain the final answer:
4/15 = 0.26667
Multiplied by 100%, 0.26667 becomes 26.7%: the percentage change in the number of students
