Answer:
h = 23
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
4h = 92
Step 2: Solve for h
Divide both sides by 4: h = 23Step 3: Check
Plug in h into the original equation to verify it's a solution.
Substitute in h: 4(23) = 92Multiply: 92 = 92Here we see that 92 does indeed equal 92.
∴ h = 23 is the solution to the equation.
What’s the side and angles?
Answer:
I think that the side length is 25.8 and the angle length is 180 degrees
Step-by-step explanation:
I'm not 100% sure but all I did was add the side lengths to get 25.8 (8.6 + 8.6 + 8.6) and the angle length is 180 degrees (because all triangles has to equal to 180 degrees and 60 plus 60 plus 60 is equal to 180).
There you go. Just to remind you that I'm not 100% sure about this answer, but hope this helps.
Emilio has 2 quarters, 4 dimes, 3 nickels and 5 pennies. How much money does Emilio have in all?
Answer:
$1.10
Step-by-step explanation:
What we know:
Emilio has 2 quarters, 4 dimes, 3 nickels, and 5 pennies.
Quarters = 0.25 * 2
Dimes = 0.1 * 4
Nickels = 0.05 * 3
Pennies = 0.01 * 5
$0.50 + $0.40 + $0.15 + $0.05
$0.90 + $0.20 = $1.10 in total

Look at the picture for the question.
Answer:
Option D: the x-intercept represents the minimum amount of photographs he must sell to pay for his photography lab.
Step-by-step explanation:
We are told that his monthly profit is given by the relation;
P = 32.5x - 845
Where x is number of pictures he needs.
We want to find what the x - intercept represents.
x intercept means that the y-value at that point is zero.
Thus, x-intercept means the profit is 0.
If profit is zero, it means his cost of operating his photography lab each month is equal to the amount of photographs he is able to sell.
Thus, it means that the x-intercept represents the minimum amount of photographs he must sell to pay for his photography lab monthly.
Richardo had saved $80 from his summer job to buy video games. He
bought 4 games and the cashier gave him $16.40 in change. If each
game cost the same amount, how much was each game?
Leave off the dollar sign in your answer.
Answer:
$15.90
Step-by-step explanation:
80 - 16.40 = 63.60
63.60÷4 =15.9
15.9 = $15.90

How many perfect cube divisors does 160,000 have?
Answer:
160,000 has three(3) perfect cube divisors namely;. 8, 8 and 125
Step-by-step explanation:
To determine how many perfect cube divisors 160,000 has;
We first need to highlight the factors of 160,000 as follows;
(2 × 2 × 2) × (2 × 2 × 2) × 2 × 2 × (5 × 5 × 5) × 5
As such, the product of numbers in each bracket yield a perfect cube; the expression above then becomes;
2 × 2 × 5 × 8 × 8 × 125.
Therefore, 160,000 has three(3) perfect cube divisors namely;. 8, 8 and 125
Dr. Brown, a veterinarian, noticed that he only had about 200 grams of cat treats left. So, he bought a new 2.5-kilogram jar. If he uses about 100 grams of cat treats every week, in how many weeks will he run out?
(Sorry if I'm asking so many questions I really need help!)
The number of weeks that they cat treats will train out is 27 weeks.
How to calculate the value?From the information given, the total grams will be:
= 200 + (2.5 × 1000)
= 200 + 2500
= 2700 grams.
Then he uses about 100 grams of cat treats every week, the number of weeks will be:
= 2700 / 100
= 27
There'll be 27 weeks.

solving multistep equations(with work shown, please)
116= -4 + 5(-6 - 5a)
8m + 4(4m -5) = -92
-3(8 - 6x) = -96
-126 = -3 (6+6x)
-8 -8(5a + 7)=-224
-2(-5x -1) = 82
-7(4x + 6) = -182
Answer:
#1) 116= -4 + 5(-6 - 5a) : a = -6
#2) 8m + 4(4m -5) = -92 : m = -3
#3) -3(8 - 6x) = -96 : x = -4
#4) -126 = -3 (6+6x) : x = 6
#5) -8 -8(5a + 7)=-224 : a = 4
#6) -2(-5x -1) = 82 : x = 8
#7) -7(4x + 6) = -182 :x = 5
Step-by-step explanation:
Remember: An equation must be equal at all times. This means if something is added to one side, it must also be added to the other. This holds true for addition, subtraction, division, and multiplication.
Problem 1:
116= -4 + 5(-6 - 5a)
move the -4 to the left side by adding 4 to both sides:
116 + 4 = -4 + 5(-6 - 5a) + 4
now 120 = 5(-6 - 5a)
divide both sides by 5:
120/5 = (5(-6 - 5a))/5
now 24 = -6 - 5a
move the -6 to the left side by adding 6 to both sides:
24 + 6 = -6 - 5a + 6
now 30 = - 5a
divide each side by -5:
(30)/-5 = (- 5a)/ -5
now -6 = a or a = -6
___________________________
Problem 2:
8m + 4(4m -5) = -92
begin by diving both sides by 4:
(8m + 4(4m -5))/4 = (-92)/4
now 2m + 4m - 5 = -23
move the -5 to the right side by adding 5 to both sides:
2m + 4m - 5 + 5 = -23 + 5
now 2m + 4m = -18
restate the left side and combine:
now 6m = -18
divide both sides by 6:
6m/6 = -18/6
so m = -3
___________________________
Problem 3:
-3(8 - 6x) = -96
divide both sides by - 3:
(-3(8 - 6x)) / -3 = -96/-3
now 8 - 6x = 32
move 8 to right side by subtracting 8 from both sides:
8 - 6x - 8 = 32 - 8
now -6x = 24
divide both sides by -6:
-6x/ -6 = 24/-6
x = -4
___________________________
Problem 4:
-126 = -3 (6+6x)
divide both sides by - 3:
-126/-3 = (-3 (6+6x)) /-3
now 42 = 6 + 6x
move 6 to left side by subtracting 6 from both sidesL
42 - 6 = 6 + 6x - 6
now 36 = 6x
divide both sides by 6:
36/6 = 6x/6
x = 6
___________________________
Problem 5:
-8 - 8(5a + 7)= -224
add 8 to both sides:
-8 - 8(5a + 7) + 8 = -224 + 8
now -8(5a + 7) = - 216
divide both sides by -8:
(- 8(5a + 7))/-8 = - 216 /-8
now 5a + 7 = 27
move 7 to right side by subtracting 7 from both sides:
5a + 7 - 7 = 27 - 7
now 5a = 20
divide both sides by 5:
5a/5 = 20/5
a = 4
___________________________
Problem 6:
-2(-5x -1) = 82
divide both sides by -2:
(-2(-5x -1))/-2 = 82/-2
now -5x -1 = -41
move -1 to right side by adding 1 to both sides:
-5x - 1 + 1= -41 + 1
now -5x = -40
divide both sides by -5:
-5x/-5 = -40/-5
x = 8
___________________________
Problem 7:
-7(4x + 6) = -182
divide both sides by -7:
(-7(4x + 6))/-7 = -182/-7
now 4x + 6 = 26
move 6 to right side by subtracting 6 from both sides:
4x + 6 - 6 = 26 - 6
now 4x = 20
divide both sides by 4:
4x/4 = 20/4
x = 5

Answer: the original slope is 3/2
The perpendicular slope is -2/3
Slope is rise/run
Step-by-step explanation: For the original slope get
Find coordinates where the graphed line crosses the grid lines at the intersections. Here, (0,-2) and (2,1) Count the number of squares vertically. That is the rise. It is the difference in y-values. It is the numerator of the fraction. Then count the squares horizontally to get the run. That is the denominator of the fraction.
It is possible to use the expression [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex] to calculate the slope.
[tex]\frac{1-(-2)}{2-0} = 3/2[/tex]
To find the perpendicular slope, reverse the sign and use the reciprocal of the original fraction.
The reciprocal of 3/2 is 2/3. The opposite sign is negative. -2/3

5w+10x
The value of the expression is 130.
Here,
The values are given as;
w = 6 and x = 10
We have to find the value of expression 5w + 10x.
What is Substitution method?
The algebraic method to solve simultaneous linear equation is called Substitution method.
Now,
The values are given as;
w = 6 and x = 10
Substitute this values in given expression, we get;
5w + 10x = 5*6 + 10*10
= 30 + 100

Step-by-step explanation:
A statue in the park is 24 feet tall and has a width of 36 inches. Chase was in
ceramics class and decided to make a model of the statue. The model is 16 inches
tall. How wide is the model (to the nearest tenth of an inch)?
Answer:
22.33 feet tall / 267.96 inches tall
Step-by-step explanation:
The statue is 36 inches wide. If Chase made his model of the statue 16 inches wide, he decreased it by 20 inches. Now change the inches into feet. 36 inches would be 3 feet, 16 inches would be 1.33 feet and 20 inches would be 1.67 feet. 24ft - 1.67 = 22.33ft. Now change the answers to inches. 22.33ft will be 267.96 inches tall.
