Answer:
x = 25°Step-by-step explanation:
Since BD is altitude, BD ⊥ AC
Therefore ∠ ADB = 90°
3x + 15° = 90°3x = 90° -15°3x = 75°x = 75°/3x = 25°A cashier contains 53 coins worth $4.40 they are all nickels and dimes right to equations that would be used to solve the system and solve

Aditya has $120 in his savings account and Sarah has $180 in her account. Each week Aditya adds $14 to his account and Sarah adds $10 to hers. How many weeks will it be before Aditya and Sarah have the same amount of money saved up? Write an equation and solve.
Sara has opened her own bakery, where customers can buy three chocolate chip cookies for $2.49. a. What is the unit price? b. What is the constant of proportionality, or k? c. In a complete sentence, explain what k means in the context of this problem.
Answer:
a) $0.83
b) k = 1.205
c) In the context of this problem, k means
The number of chocolate chip cookies increases as the price increases because number of chocolate chip cookie is directly proportional to its price
Step-by-step explanation:
Sara has opened her own bakery, where customers can buy three chocolate chip cookies for $2.49.
a. What is the unit price?
The unit price means the cost of 1 cookie
Hence:
3 chocolate chip cookies = $2.49
1 chocolate chip cookies = x
3x = $2.49 × 1
x = $2.49 × 1/3
x = $0.83
Hence, the unit price = $0.83
b. What is the constant of proportionality, or k?
Chocolate chip cookie ∝ Price
Chocolate chip cookie is directly proportional to the Price
C = kP
Where k is constant of proportionality
k = Chocolate chip cookie/Price
k = C/P
Hence,
k = 3/2.49
k = 1.2048192771
k = 1.205
c. In a complete sentence, explain what k means in the context of this problem.
In the context of this problem, k means
The number of chocolate chip cookies increases as the price increases because number of chocolate chip cookie is directly proportional to its price

Lydia is deciding between two different movie streaming sites to subscribe to. Plan A costs $5 per month plus $2.50 per movie watched. Plan B costs $24 per month plus $1.50 per movie watched. Let A represent the monthly cost of Plan A if Lydia watches & per month, and let B represent the monthly cost of Plan B if Lydia watches x movies per month. Write an equation for each situation, in terms of x, and determine which plan would be cheaper if Lydia plans on watching 21 movies each month.
Answer:
A= 2.50x+52.50x+5
B= 1.50x+241.50x+24
Step-by-step explanation:
Plan B is $2 cheaper than Plan A when watching 21 movies.
Lydia Plan B would be 2 dollars cheaper than plan A.
Equation on each plan are:
A = 2.50x + 5
B = 1.50x + 24
Lydia deciding between two different movie streaming site to subscribe to.
Lydia have two plan, Plan A and Plan B.
What is Linear equation in one variable?
The linear equation in one variable is an equation which is represent in the form of ax + b = c, where a and b are two integers and x is a variable and has only one solution.
Here, Plan A costs $5 per month plus $2.50 per movie watched.
A = 5 + 2.50 x
here, x is movies per month.
And Plan B costs $24 per month plus $1.50 per movie watched.
B = 24 + 1.50 x
When Lydia plans on watching 21 movies each month.
x = 21
⇒ A = 5 + 2.50 (21) = 57.50
⇒ B = 24 + 1.50 (21) = 55.50
So, Lydia Plan B would be 2 dollars cheaper than plan A.

Manny is buying new clothes for school. He buys three shirts for $14.95 each and a tie for $12. Everything in the store is on sale for 15% off. What is Manny's total cost?
Given:
Cost of each shirt = $14.95
Cost of a tie = $12
Discount on Sale = 15% off
Manny buys three shirts and a tie.
To find:
The Manny's total cost.
Solution:
We have,
Cost of 1 shirt = $14.95
Cost of 3 shirt = 3 × $14.95
= $44.85
Cost of a tie = $12
Total cost before discount = Cost of 3 shirt + Cost of a tie
= $44.85 + $12
= $56.85
Everything in the store is on sale for 15% off. So,
[tex]\text{Manny's total cost}=56.85-\dfrac{15}{100}\times 56.85[/tex]
[tex]\text{Manny's total cost}=56.85-0.15\times 56.85[/tex]
[tex]\text{Manny's total cost}=56.85-8.5275[/tex]
[tex]\text{Manny's total cost}=48.3225[/tex]
Therefore, the Manny's total cost is $48.3225.

3. m∠A < 80°
Step-by-step explanation:
The exterior angle NGS, marked as 80°, has a measure that is the sum of the measures of the remote interior angles: GAN, GNA.
If we assume that angle measures cannot be zero, then we must have ...
m∠A +m∠N = 80°
m∠A = 80° -m∠N
Since m∠N > 0, the measure of angle A must be less than 80°.
This conclusion matches choice 3.

what is the final step in the inequality -2(5-4x)<6x-4
Answer:
x < 3
Step-by-step explanation:
-2(5-4x)<6x-4
In this inequality, we are to solve for x using the steps below;
-2(5-4x)<6x-4
Expand the parentheses on the left hand side of the expression;
-10 + 8x < 6x - 4
Collect like terms to both sides;
-10 + 4 < 6x - 8x
-6 < -2x
Divide both sides by - 2; Note the sign of the inequality changes;

You are making a new type of deodorant from two different mixtures the first mixture is 30% smell proof and the second mixture is 80% smell proof to make a safe make sure it needs to be 50% smell proof how much of each makes you need if you want 1000 L total
Answer:
600 L of 30% proof and 400 L of 80% proof is needed
Step-by-step explanation:
Let the amount of 30% smell proof be x while that of 80% smell proof is y
Then;
x + y = 1000 •••••(i)
Also;
30% of x + 80% of y = 50% of 1000
0.3x + 0.8y = 500 •••••(ii)
From i, x = 1000 - y
Put this into ii
0.3(1000-y) + 0.8y = 500
300 - 0.3y + 0.8y = 500
0.5y = 500-300
0.5y = 200
y = 200/0.5
y = 400 L
But x = 1000 - y
x = 1000 - 400 = 600 L
