If three times a number is increased by 24, the result is 16 less than seven times the same number. Find the number.
Answers
Answer:
10
Step-by-step explanation:
let x = unknown number
three times x is increased by 24
so 3x + 24
this is equal to 16 less than 7 times x
so 3x + 24 = 7x - 16
we now solve for x
3x + 24 = 7x - 16
add 16 to both sides
3x + 24 + 16 = 7x - 16 + 16
3x + 40 = 7x
subtract 3x from both sides
3x - 3x + 40 = 7x - 3x
40 = 4x
divide both sides by 4
40/4 = 10
4x / 4 =x
x=10
the unknown number is 10

Which sequence is geometric and which is arithmetic?
Answers
The table on the left is arithmetic
This is because each term is increasing by the same amount (2) each time.
3+2 = 55+2 = 77+2 = 99+2 = 11--------------------------------------------
The table on the right is geometric
Why? Because this time we are multiplying each term by the same value (2) to get the next term.
3*2 = 66*2 = 1212*2 = 2424*2 = 48Both involve the number 2, but the first table uses addition while the second table uses multiplication.
1) Arithmetic
~3,5,7
common difference of 2
2)Geometric
~3,6,12
each term is found by multiplying the previous one by a fixed number

A triangle has vertices at (−2, −2), (−2, −5), and (−4, −5). The triangle is translated 2 units to the right and rotated 90° clockwise about the origin. What are the coordinates of its image?
( , ), ( , ), ( , ) → ( , ), ( , ), ( , ),
Answers
Step-by-step explanation:
translated (shifted) 2 units to the right (positive x direction) creates the points
(-2 + 2, -2) = (0, -2)
(-2 + 2, -5) = (0, -5)
(-4 + 2, -5) = (-2, -5)
and now we rotate these points 90° clockwise around the origin.
that means a positive x turns into a negative y, a negative y into a negative x, a negative x into a positive y, and a positive y into a positive x.
and a 0 just trades places.
therefore,
(0, -2) becomes (-2, 0)
(0, -5) becomes (-5, 0)
(-2, -5) becomes (-5, 2)
so, overall
(-2, -2) becomes (-2, 0)
(-2, -5) becomes (-5, 0)
(-4, -5) becomes (-5, 2)

Answer:
A. 1.06
B. $6,784
Step-by-step explanation:
I = A - P = $384.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Solving our equation:
A = 6400(1 + (0.06 × 1)) = 6784
A = $6,784.00
The total amount accrued, principal plus interest, from simple interest on a principal of $6,400.00 at a rate of 6% per year for 1 year is $6,784.00.
