Solve for t.
Reduce any fractions to lowest terms. Don't round your answer, and don't use mixed fractions.
4t - 3 > 37t - 50
Answers
Answer:
4t - 3 > 37t - 50
Step-by-step explanation:
Step 1: 4t - 3 > 37t - 50
-4t -4t
-3 > 33t - 50
+50 + 50
47 > 33t
33 33
t < 47/33
The value for t in the given inequality 4t - 3 > 37t - 50 after solving the inequality is t < [tex]\frac{47}{33}[/tex].
Given an inequality:
4t - 3 > 37t - 50
It is required to find the value of t after solving the inequality.
In order to solve the inequality, write the inequality such that the like terms are on the same side.
Here the like terms in variables are 4t and 37t which are on opposite sides.
The like terms in constant are -3 and -50 which are also on opposite sides.
Consider the inequality:
4t - 3 > 37t - 50
Add 3 on both sides.
4t > 37t - 47
Subtract 37t on both sides.
-33t > -47
Divide both sides by -33. Then the inequality sign also switches to its opposite sign.
t < [tex]\frac{47}{33}[/tex]
Hence the solution of the given inequality is any number t whose value is less than [tex]\frac{47}{33}[/tex].

Answer:
C. x = 5, y = 7
Step-by-step explanation:
Diagonals of a parallelogram bisects each other. Therefore:
[tex] 2x = y + 3 [/tex], and,
[tex] x + 2 = y [/tex]
✔️To find the value of x, substitute y = (x + 2) in [tex] 2x = y + 3 [/tex].
Thus:
[tex] 2x = (x + 2) + 3 [/tex]
[tex] 2x = x + 2 + 3 [/tex]
[tex] 2x = x + 5 [/tex]
Subtract x from each side
[tex] 2x - x = 5 [/tex]
[tex] x = 5 [/tex]
✔️To find y, substitute x = 5 in [tex] x + 2 = y [/tex].
Thus:
[tex] 5 + 2 = y [/tex]
[tex] 7 = y [/tex]
[tex] y = 7 [/tex]

Step-by-step explanation: Any number raised to a negative exponent, essentially means you reciprocal to get rid of the negative. After that, you do the math for the number in the denominator, without considering the negative sign. You could also do it the other way, do the function first without the negative, 3^3 is 27 and then applying the negative, reciprocal it to 1/27.

In the previous question, we determined that if you borrow $3,000 on an 8% discounted loan for 9 months, the amount you actually receive will be $2,820. Given this, what is the effective interest rate on the loan you receive? Express your answer as a percentage rounded to the nearest tenth of a percent if necessary, but do not include the percent sign.
Answers
Answer: 8.5%
Step-by-step explanation:
I=Prt
180=(2,820)r(3/4)
180=2,115r
R=180/2,115
r≈8.5%
The effective interest rate is approximately 8.5%, about half a percent higher than what was advertised.

Step-by-step explanation:
PR = PQ + QR
10x - 45 = 3 + x + 6 {Combine like terms}
10x - 45 = 9 + x {Subtract 'x' from both sides}
10x - x - 45 = 9
9x - 45 = 9 {Add 45 to both sides}
9x = 9 +45
9x = 54
x = 54/9
x = 6
PR = 10x - 45
= 10*6 - 45
= 60 - 45
