If 120% of a is equal to 80% of b, then what is the value of a+b in terms of a and b?
Answers
80% of b
120% = 120/100 =1.2
80%= 80/100 = 0.8
1.2a=0.8b | ÷1.2
1a = 2/3 b
1.2a=0.8b | ÷0.8
1b=1.5a
(a+b) = ((2/3b)+ (1.5a)) =2/3b + 1.5a
*not 100% sure
Answer:
120/100 a = 80/100 b
12/10 a = 8/10 b
10 (12/10) a = 10 (8/10) b
12a= 8b
3a= 2b
a+b in terms of a
b = 3/2×a
a+ 3/2×a = 5/2×a
a+b in terms of b
a = 2/3×b
b + 2/3.b = 5/3×b

Answers
Answer:
67 degrees or 113 degrees.
Step-by-step explanation:
The other angle is 67 degrees because a complementary angle adds up to 90 degrees. It could also be 113 because that is 23 degrees more than a complementary angle.

a car drives 10 1/2 miles in 1/6 hour. what is its speed in miles per hour
Answers
The speed for the given distance and time is 12.6 miles per hour.
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
Given that, a car drives [tex]10\frac{1}{2}[/tex] miles in 1/6 hour.
We know that, the formula to find the speed is Speed=Distance/Time
Speed = [tex]10\frac{1}{2}[/tex] ÷ 1/6
= 21/10 ×6/1
= 63/5
= 12.6 miles per hour
Therefore, the speed for the given distance and time is 12.6 miles per hour.

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.
