Eight times the square of a negative
integer plus 24 times the negative
integer equals 80. Find the unknown
negative integer.
Answer:
-2
Step-by-step explanation:
8(-a)^2+24*-a=80
or,8a^2-24a=80
or,8a^2-24a-80=0
or,8(a^2-3a-10)=0
or,a^2-3a-10=0
or,a^2-(5-2)a-10=0
or,a^2-5a+2a-10=0
or,a(a-5)+2(a-5)=0
or,(a-5)(a+2)=0
either,
a-5=0
•°•a=5
or,
a+2=0
•°•a=-2(negative integer)
The value of the unknown integer is -2.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given data eight times the square of a negative integer plus 24 times the negative integer equals 80 in the form of the mathematical expression will be written as:-
8(-a)²+24-a=80
8a²-24a=80
8a²-24a-80=0
8(a²-3a-10)=0
a²-3a-10=0
a²-(5-2)a-10=0
a²-5a+2a-10=0
a(a-5)+2(a-5)=0
(a-5)(a+2)=0
a-5=0
a=5 or, a+2=0 a=-2
Therefore, the value of the unknown integer is -2.

Rates Lin, Diego, and Elena are competing to see who can finish their book the fastest. Lin read the first 54 pages from a 270-page book in the first 3 days. Diego read the first 100 pages from a 320-page book in the first 4 days. Elena read the first 160 pages from a 480-page book in the first 5 days. If they continue to read every day at these rates, who will finish first, second, and third? Explain or show your reasoning:
Answer:
Diego will finish first while Lin and Elena would finish reading their book at the same time
Step-by-step explanation:
Rates Lin, Diego, and Elena are competing to see who can finish their book the fastest.
Their rates is calculated as:
For Lin
Lin read the first 54 pages from a 270-page book in the first 3 days.
54 pages = 3 days
270 pages = x
Cross Multiply
54x = 270 × 3
x = 270 × 3/54
x = 15 days
For Diego
Diego read the first 100 pages from a 320-page book in the first 4 days.
100 pages = 4 days
320 pages = x days
Cross Multiply
100x = 320 × 4
x = 320 × 4/100
x = 12.8 days
For Elena
Elena read the first 160 pages from a 480-page book in the first 5 days.
160 pages = 5 days
480 pages = x days
Cross Multiply
160x = 480 × 5
x = 480 × 5/160
x = 15 days
If they continue to read every day at these rates, who will finish first, second, and third?
Diego will finish reading his book first while Lin and Elena would finish reading their book at the same time
Answer:
Diego will finish first while Lin and Elena would finish reading their book at the same time

Answer:
64 bags
Step-by-step explanation:
number of bags sold by Takis Scorpion BBQ = x
Number of bags sold by Takis Valcano Quesco = 3x - 6
the total number of bags = x + ( 3x - 6 )
x + 3x - 6 = 250
therefore, 4x - 6 = 250
4x = 250 + 6
4x = 256
dividing through by 4
x = 64

Answer:
y = -6/5x + 2
Answer:
5\6x-2
Step-by-step explanation:
Y=(10-6x)\5
Y= 2-6\5x
Slope of line 1 = -6\5
Slope of line 2*(slope of line 1 )= -1
Slope of line 2 *-6\5=-1
Slopes of line 2 = 5\6
(X-x0)m = y-y0
(X-6)*5\6=y-3
5\6x -5 = y-3
Y= 5\6x -2
In △ABD, altitude AC¯¯¯¯¯ intersects the right angle of triangle ABD at vertex A. BC=4.2 in. and CD=9.6 in..
What is the length of AC¯¯¯¯¯?
Answer:
AC = 6.35 in.
Step-by-step explanation:
BC times CD
4.2(9.6) = 40.32
The square root of 40.32 = 6.3498031465550174172038778087342
Round your answer to the nearest hundredth
AC = 6.35 in.
