The measures of the angles of a triangle are shown in the figure below. Solve for x.
(2x+12)°
42°
Answers
-12. = -12
2x = 30
Divide by 2 = divided by 2
X= 15
That how you solve it
Explanation: So we know that when you add all angles together of a triangle it has to equal 180° and we know that one of the angles is 90° another is 42° and the last one is (2x+12)° so our equation would be
180=90+42+(2x+12)
add all the numbers that we can and get
180=2x+144
now subtract 144 from both sides so we could have the 2x by itself
36=2x
now to find the x we need to get rid of the 2 so we divide by 2 on both sides and get
18=x

If you double a number, you will get the same as the triple of one-fourth of 24. What is the number?
Answers
Answer:
x = 9
Step-by-step explanation:
Let's write an equation.
2x = 3 x (24 x 1/4)
2x = 3 x 6
2x = 18
x = 9
Hope that helps!
Triple one fourth of 24 = 6 x 3 = 18
Half of 18 = 18/ 2 = 9
9 can be double to get the same answer as the triple of one fourth of 24.

Translate the new algebraic expression you created in Question 1 to a verbal expression.
Answers
Answer:
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
Q1. 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.
25(10j + 18 + 5j)
Your expression is good.
Q2. Translate the new algebraic expression you created in Question 1 to a verbal expression.
Skuttle offered to pay his sister Izzy $25 for every four leaf clover she finds in the woods. Izzy finds 18 clovers but decides to get Roxy’s help. Izzy finds clovers twice as fast as Roxy but they will over all make more money together.
Your verbal expression is good. It refrects your chosen equation.
Part 2: Writing Equivalent Expressions
Q3. Use your knowledge of the mathematical properties to create two equivalent algebraic expressions for the algebraic expression you created in Question 1. Explain how you arrived at the equivalent expressions by showing all your steps and stating which properties you used.
Using commutative property of addition, the expression in question 1 can be rewritten as follows:
25(10j + 18 + 5j) = 25(10j + 5j + 18)
Using distributive property of multiplication over addition, the expression in question 1 can also be rewritten as follows:
25(10j + 18 + 5j) = 250j + 450 + 125j
Q 4. Use substitution to prove your algebraic expressions are equivalent. You may substitute any number for the variables you choose. Show all your work for complete credit.
Now we can subsitute, say 7 for j.
For the first expression, we have:
25(10j + 5j + 18) = 25(10(7) + 5(7) + 18)
= 25(70 + 35 + 18) = 25(123) = 3,075.
For the second expression, we have:
250j + 450 + 125j = 250(7) + 450 + 125(7) = 1,750 + 450 + 875 = 3,075.
Thus, we can see that both expressions are equivalent.
Part 3: Finish the Story
Q5. 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?
Sarah found 3 + 7 = 10 shark teeth.
John found 10 / 2 = 5 shark teeth.
The total money they earned is $5 x 15 = $75.

The area of the shaded square is 125 square inches. The length of the unshaded rectangle is 7√5 inches.
The estimated value of the length of the shaded square is ___ inches. The estimated value of the area of the unshaded rectangle is ___ square inches.
Answers
Answer:
Question incomplete
Step-by-step explanation:
The estimated value of the length of the shaded square is 5 inches. The estimated value of the area of the unshaded rectangle is 35√5 square inches.
What is the area?The space filled by a flat form or the surface of an item is known as the area.
The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters and other similar units are used to measure area.
Given data;
The area of the shaded square = 125 square inches.
Length of the unshaded rectangle, b= 7√5 inches
The side of the square is a;
A = 125 square inches
l²= 5² square inches
l = 5 inch
The area of the unshaded rectangle is;
A' = l × b
A'=5 ×7√5
A'=35√5
Hence, the estimated value of the length of the shaded square is 5 inches. The estimated value of the area of the unshaded rectangle is 35√5 square inches.
