the difference between 13 fours and 6 fours
Answers
Answer:
The lesson activity requires students to use up to four fours and any operation to make the numbers from 0 to 100. For example, 4 + 4 + 4 + 4 = 16.
Initially, students will use the more familiar operations, +, −, ×, ÷, along with brackets to create their equations. For example, (4 × 4 + 4) ÷ 4 = 5. Gradually, finding solutions for the remaining numbers in the list becomes more challenging. Here, it is a good opportunity to introduce some other operations to the students, including √4 = 2 and 4! = 24. In my experience, at least one student in the class will be familiar with the square root operation √n, which will make it easier to introduce. The other operation n!, known as factorial, will be less familiar to students.
n! is the product of all positive integers less than or equal to n; for example, 4! = 4 × 3 × 2 × 1 = 24, or 3! = 3 × 2 × 1 = 6
With the introduction of these two less familiar operations, the number of solutions that students can find to the initial problem increases.

it's c because in the triangle you can see the lines of congruence. Letter L only has only one and so does y. both x and n have 2 lines of congruence. and m and z have 3.
LNM goes to YXZ
notice how the first letter goes to the first letter of the second triangle and so on
LNM goes to YXZ

What does the variable r represent in the equation 10r+4=8
Answers
Answer:
The value of variable r in the equation [tex]10r+4=8[/tex] is [tex]\mathbf{r=0.4}[/tex]
Step-by-step explanation:
We need to find the value of variable r in the equation [tex]10r+4=8[/tex]
Step 1: Write the equation
[tex]10r+4=8[/tex]
Step 2: Subtract 4 on both sides
[tex]10r+4-4=8-4\\10r=4[/tex]
Step 3: Divide both sides by 4
[tex]\frac{10r}{10}=\frac{4}{10}\\r=0.4[/tex]
So, The value of variable r in the equation [tex]10r+4=8[/tex] is [tex]\mathbf{r=0.4}[/tex]
Marley used 7 cups of water to make 4 loaves of French bread. What equation can be used to model the total cups of water needed y for making x loaves of French bread? Write the equation in the form y =kx .
Answers
Answer:
[tex]\displaystyle y=\frac{7}{4}.x[/tex]
Step-by-step explanation:
Proportional Relationship
It's the type of relationships between two variables where their ratios are equivalent.
In a proportional relationship, one variable is always a constant value by the other. That constant is known as the constant of proportionality.
A proportional relationship between the variables x and y is written as:
y=k.x
For this problem, y represents the cups of water needed for making x loaves of French bread.
We know Marley used y=7 cups of water to make x=4 loaves of French bread. Substituting into the equation:
7=k.4
Solving for k:
[tex]\displaystyle k=\frac{7}{4}[/tex]
The equation to model the problem is:
[tex]\mathbf{\displaystyle y=\frac{7}{4}.x}[/tex]
Rob sells electronics and earns $625 per week, plus 12% of his sales. Last week, he sold $3250 worth of electronics. What was his total earnings for last week?
Answers
Answer:
$1,015
Step-by-step explanation:
Given that:
Weekly earning = $625
Commission = 12% of sales
sales made last week = $3250
Last week earning = weekly earning + commision on sale
Commission on sale = 12% of sales
Commission on sale = (0.12 * 3250) = $390
Last week earning = weekly earning + commision on sale
Last week earning = $625 + $390 = $1,015

graph the line -1 passing through the point (-4,5)
Answers
Answer:
Step-by-step explanation:
If you want to find the equation of line with a given a slope of which goes through the point (-4,5), you can simply use the point-slope formula to find the equation:
---Point-Slope Formula---
where is the slope, and is the given point
So lets use the Point-Slope Formula to find the equation of the line
Plug in , , and (these values are given)
Distribute
Multiply and to get
Add -1 to both sides to isolate y
Combine like terms and to get the answer
So the equation of the line with a slope of which goes through the point (-4,5) is:
which is now in y=mx = b form where the slope is m=-4/5 and the y-intercept is b=1
What the slope of (0,5) and (8,2)
