Answer:
x=4
Step-by-step explanation:
x + 2y = 10
x + 2(3) = 10
x + 6 = 10
-6 -6
x = 4
[tex]x + 2y = 10 \\x + 2(3) = 10 \\ x + 6 = 10 \\ x = 10 - 6 \\ x = 4[/tex]

Answer:
40.25 feet tall
Step-by-step explanation:
There is a small triangle made by the boy and the three feet of shadow. This triangle when scaled up will be the same as the flag and the full shadow.
To do this you need to find how much to multiply 3 by to get 23.
First you do 23/3 which will give you 7.6 repeating. or 7.6666666666... (same thing)
If you then multiply that number by the boy's height 5.25 you will get the answer 40.25.
This is because the triangle the flag creates is 7.666... times larger than the triangle the boy creates.
I need help with 11 and 12 pls due soon!!
Answer:

The cost for 16 ounces of cheese is $3.20. What is the cost for 20 ounces of cheese?
Answer:
It costs $4 dollars for 20 ounces of cheese.
Step-by-step explanation:
First we find out how many dollars for 1 ounce of cheese.
3.20 ÷ 16 = 0.2
Next we multiply 0.2 by 20.
20 * 0.2 = 4
So, the answer is 4 dollars.
Hope this helps! :)
You can find price of 1 ounce of cheese, then find cost of 20 ounces of cheese by simply using multiplication.
The cost for 20 ounces of cheese is $4.00
Given that:The cost for 16 ounces of cheese is $3.20To find:Cost for 20 ounces of cheese
Finding cost of 1 ounce of cheese:[tex]16 \: \rm ounce = \$3.20\\\\\\ \text{Dividing by 16 on both sides}\\\\ 1 \rm \: ounce = \dfrac{3.20}{16} = \$0.2[/tex]
Finding cost of 20 ounces of cheese:Multiplying both sides of above equation by 20, we get:
[tex]1 \rm \: ounce = \dfrac{3.20}{16} = \$0.2\\ \\ 20 \times 1 \rm \: ounce = 20 \times \$0.2\\ 20 \text{\:ounce of cheese \:}= \$4[/tex]
Thus, the cost for 20 ounces of cheese is $4.00

Radio broadcasters joke about the number of people who start leaving Ranger Stadium during the seventh inning of baseball games. One evening, during a particularly boring baseball game in which the Rangers were trailing by six runs after six innings, the fans began to leave at a record pace. After the first out in the top of the seventh inning, 100 fans left. After the second out, 150 fans left. After the third out, 200 fans left. The pattern continued in this way, with 50 more fans leaving after each out than had left after the previous out. The ridiculous thing was, the Rangers tied up the game in the bottom of the ninth inning, and people still kept leaving early. The game lasted then innings (The Rangers lost anyway), and the pattern continued through the bottom of the tenth inning, How many fans left early? Work this problem carefully.

The two scalene triangles seen below are similar figures. What is the scale factor from the small scalene triangle on the left to
the large scalene triangle on the right? The scalene triangles are not drawn to scale.
Answer:
scale factor= 4.7
Step-by-step explanation:
47/10= 4.7
32.9/7= 4.7
28.2/6= 4.7
To figure out the scale factor for the smallest to the largest triangle, divide the larger number by the smaller number (of the same side).
If you wanted to get the scale factor of the largest to smallest triangle, you would just do the opposite.

Module 06: Project Option 1
Instructions:
Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.
Sarah can use the expression 5(2j + 3 + j) to represent the amount of money they can earn.
Part 1: Writing Expressions
1. Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.
2. Translate the new algebraic expression you created in Question 1 to a verbal expression.
Part 2: Writing Equivalent Expressions
3. You will now use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.
a. Use either the commutative property or combine like terms to create an equivalent expression.
b. Use the distributive property to create an equivalent expression.
4. Pick a number from 1 to 10. Use that number to verify your three expressions (the original, the one from 3a, and the one from 3b) are equivalent by substituting it into each expression. Show all your work for complete credit.
Part 3: Finish the Story
5. Write a few sentences to end Sarah’s story. How many shark teeth did she find? How many shark teeth did John find? How much money did they earn?
6. Choose a method to present your assignment. You may submit your work in a Word Document or you may choose to develop a PowerPoint presentation or video recording of yourself. Use your creativity! Make sure to include the information from all three parts in your Word Document or presentation.

What inverse operation would you perform on both sides to solve this equation?
4-c=26 and solve it pls
Answer:
c=-24
Step-by-step explanation:
You should perform the inverse of addition and multiplication
The inverse of addition is subtraction so we subtract 4 on both sides:
4-4-c=26-4
Which will be
-c=24
Divide by -1 since the inverse of multiplication is division
-c/-1=24/-1
So the answer will be:
c=-24
