Step-by-step explanation:
Explanation: QT = x +4
Use proportions: x +4/ 4 = 9/3
Cross Multiply: 3(x+4) = 36
Solve 3x+12 = 36
x=8
Plug back into equation: 8 +4 = 12

Isaac has three types of coins in his pocket. There are two more quarters than dimes, and as many nickels as quarters and dimes together. The coins total $3.75. How many quarters, dimes, and nickels are in Isaac's pocket?
Answers
Answer:
There are 16 nickels, 7 dimes, and 9 quarters.
Step-by-step explanation:
Aight, so lets set dimes as "x". Since there are 2 more quarters than dimes, quarters is "x+2". And since nickels is equal to dimes plus quarters, nickels takes the role of "(x+2)+x". We can simplify this by adding x and x together, so nickels is "2x+2" In this example, I'm converting these variables to cents, since it's easier than converting to dollars. Since a dime is 10 cents, 10 times x is"10x". Quarters are worth 25, so first we do x times 25 (25x) and then 2 times 25 (50). Then nickels. 2x+2 times 5 is 10x + 10. Alright, so now we have our cent values. $3.75 is 375 cents, so now we can make an equation:
10x + 25x + 50 + 10x + 10 = 375 cents.
I'm guessing you already know how to solve an equation, first combine like terms, then figure out how many times the variable goes into the numerical value. You should end up with 7, which is dimes. If we go back to our problem, we see that there are 2 more quarters, so 7+2= 9 quarters. As for nickels (9+7) there are 16 nickels.
There's probably a more efficient way to do this, but since I'm so... uh... inefficient, this is the best explanation I can do :p

Shamika bought 3 skirts that cost $25 each before the discount. What was her total after thediscount?
A. $45.00
B. $48.75
C. $52.50
D. $56.25
Answers
Answer:
The answer is C and please give me brainliet And a like!
Where the above parameters are given, Shamika's total after the discount is $56.25. (Option D)
How to compute the above resultAccording to the table, if the total purchases are less than $50, the discount is 25%.
Shamika bought 3 skirts at $25 each, so her total purchase amount is 3 * $25 = $75.
Since $75 is less than $50, she qualifies for a 25% discount.
To calculate the discount, we multiply the total purchase amount by the discount rate -
Discount = 25% of $75 = (25/100) * $75 = $18.75
To find her total after the discount, we subtract the discount from the total purchase amount -
Total after discount = Total purchase amount - Discount
Total after discount = $75 - $18.75 = $56.25
Therefore, Shamika's total after the discount is $56.25. (Option D)

Answer:
x = 4
y = 4√3
Step-by-step explanation:
Reference angle = 30°
Hypotenuse = 8
Adjacent = y
Opposite = x
Recall: SOHCAHTOA
✔️To find x, apply SOH:
Sin 30 = Opp/Hyp
Sin 30 = x/8
x = 8 × sin 30
x = 8 × ½ (sin 30 = ½)
x = 4
✔️To find y, apply CAH:
cos 30 = Adj/Hyp
Cos 30 = y/8
y = 8 × Cos 30
y = 8 × √3/2 (cos 30 = √3/2)
y = 4 × √3
y = 4√3

x = 15
Step-by-step explanation:
We know that 4x° + 8x° make a straight angle of 180°.
4x° + 8x° = 180°
12x° = 180°
12x = 180
x = 180/12 = 15
Answer:
x=15
Step-by-step explanation:
I gotcha bro
The line C is straight and straight lines are 180°
so 180° = 4x + 8x = 12x ----> 180 = 12x ---> then divide both sides by 12
180/12 = 15 and 12x/12 = x
so 15 = x or x = 15
