Answer:
Shirt: $45 , Tie: $12
Step-by-step explanation:
Let s be the price of the shirt
Let t be the price of the tie
Given the information from the question,
s + t = 57 - Equation 1
s - t = 33 - Equation 2
We will use substitution method to find the prices.
We will rearranging equation 1.
s = 57 - t
We will substitute s into equation 2.
57 - t - t = 33
57 - 2t = 33
-2t = 33 - 57
-2t = -24
t = -24 / -2
= 12
We now substitute t into Equation 1.
s + 12 = 57
s = 57 - 12
= 45
From here we know, the shirt costs $45 and the tie costs $12

Answer:
A. (1,7)
Step-by-step explanation:
The format when pairing coordinates and coordinate plane is
(X,Y) a.k.a. (horizontal,vertical) That is where the other two lines intersect
<span>a. 2x + 11y when x = 4 and y = 2 is 2(4) + 11(2) = 8 + 22 = 30
</span><span>b. 4(y + 1) when y = 7 is 4(7 + 1) = 4(8) = 32
</span><span>c. 3x when x = 12 is 3(12) = 36
</span><span>d. x + 8y when x = 8 and y = 3 is 8 + 8(3) = 8 + 24 = 32
Options a and d have a value of 32. </span>
Answer:
4.06 inches, or about 4 inches.
Step-by-step explanation:
The value of pi is a <em>circle's circumference divided by its diameter</em>.
Here, the equation is <em>40.6 ÷ 10</em>.
The quotient of 40.6/10 is 4.06 inches.
I assume the approximate value will be among the range of <em>4 inches through 4.1 inches</em>.
