Answer:
25h = x
Step-by-step explanation:
If x is the variable for how many pages she reads in total, 25 multiplied by h (the number of hours) will give you the total pages read!
simplify the expression 4b-24+19
4b - 24 + 19 = 4b - (-24 + 19) = 4b - 5
The simplified expression becomes: 4b - 5
Here, we have,
To simplify the expression 4b - 24 + 19,
we can combine the like terms.
The like terms in the expression are the terms without a variable (constant terms) and the terms with the same variable raised to the same power.
Let's simplify step by step:
First, combine the constant terms -24 and 19:
-24 + 19 = -5
Now, the simplified expression becomes:
4b - 5

Javonie started a dog walking business over the summer. He walked 8 dogs and earned $160 in July.
He walked 9 dogs and earned $180 in August.
a. How much money did he earn over the summer?
b. How much did he charge per dog in July?
*Determine what you need to find.
*Set up the problem.
*Solve.
*Check.
Answer:
a) $340
b) $20
Step-by-step explanation:
a) in the summer (July and August) he earned 160 + 180 = $340
b) in July he earned 160 ÷ 8 = $ 20
Javonie earned $340 over the summer and he charged $20 per dog in July.
The amount of money he earned over the summer is the sum of the money he earned in July and the sum of the money he earned in August
Total amount earned in the summer = amount earned in July + amount earned in August
$160 + $180 = $340
The amount he charged per dog in July can be determined by dividing the total amount earned in July by the total number of dogs he walked.
Amount charged per dog = amount earned in July / total dogs worked
$160 / 8 = $20

Find the equation of the line with x-intercept 4 and y-intercept -1 in slope-intercept
form.
Answer:
Step-by-step explanation:
The slope-intercept form is y=mx+b, where m is the slope and b is the y-coordinate of the y-intercept, so we can already conclude that b=-1.
This results in y = mx - 1
We also have the x-intercept, and we know that the y-coordinate of an x-intercept is always 0. This means that we have the point (4,0). Substitute this into the formula to generate m:
0 = 4m - 1
4m = 1
m = 1/4
thus y = [tex]\frac{1}{4}[/tex]x - 1
are the ratios 1:3 and 2:4 equivalent

What is chemical formula ?A chemical equation is a phrase that enumerates a compound's component elements and their respective weights. If there is just single atom of a particular sort, no subscript is necessary. If an atom contains three or more of a specific type of atom, a subscript is appended to a symbol for that atom.

Briefing:
Both graphite and diamond are carbon allotropes. Although graphene and fullerenes are among the rarer unusual allotropes of carbon, they do exist. An enormous three-dimensional network of carbon atoms makes up a diamond.
we know that is the importance of chemical formula :
Chemical equations provide details about the chemical composition of a compound. They also represent the proportions in which the compound's individual components come together to create the compound. The chemical formula of a compound is crucial when describing it in a chemical equation.

The "A" or the "C"? plz
Answer:
A: 4
Step-by-step explanation:
The rise is 4
You can see that by noticing points (-1,-1) and (0,3)
The distance between the y values, -1 and 3 is 4 units
The run is 1
As it rises four units, it runs 1 unit
The difference between 0 and -1 is 1
Slope is calculated by rise/run
4/1 = 4 so the slope is 4
