Caleb solved this equation and recorded his work.
7.4x + 4.1(2x − 4) = −2.3(x − 6) − 21.6
1. 7.4x + 8.2x − 16.4 = −2.3x + 13.8 − 21.6
2. 15.6x − 16.4 = −2.3x + 35.4
3. 17.9x − 16.4 = 35.4
4. 17.9x = 51.8
5. x ≈ 2.89
When Caleb verified his solution, it didn’t work. What mistake did he make?

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 6, 4, 8/3... Find the 7th term.
Answers
Answer:
0.527
Step-by-step explanation:
The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 6, 4, 8/3... Find the 7th term
The sequence given in the above Question is a geometric sequence.
The formula for the nth term of a geometric sequence is given as:
an = a × r ^n - 1
Where
a = First term
r = Common ratio
n = nth term
From the above question, we are asked to find the 7th term
Hence:
a = 6
Common ratio = Second term/first term
= 4/6 = 2/3
n = 7
The 7th term = 6 × (2/3 )^7 - 1
= 6 × (2/3)^6
= 6 × (2/3)⁶
= 0.5267489712
Approximately to the nearest thousandths the 7th term = 0.527
A carpenter has at most $250 to spend on lumber. The inequality 8x+12y≤250 represents the numbers x of 2-by-8 boards and the numbers y of 4-by-4 boards the carpenter can buy. Can the carpenter buy twelve 2-by-8 boards and fourteen 4-by-4 boards?
Answers
Answer:
No, (12, 14) this is not a solution of the inequality
Step-by-step explanation:
(x, y)
x = 12 2-by-8 boards
y = 14 4-by-4 boards
(12, 14)
8x + 12y <= $250
This means that a 2-by-8 board cost $8 each, while a 4-by-4 board cost $12 each.
8(12) + 12(14) <= 250
96 + 168 <= 250
264 <= 250
264 is not less than or equal to 250

if y=3x^3+x^2-5 and z=x^2-12 what polynomial is equivalent to 2(y+z)
Answers
Answer:
2y + 2z
6x³+2x²-10 + 2x²-24
6x³+4x²-34 ■
Step-by-step explanation:
The polynomial which is equivalent to 2 (y + z) is 6x³ + 4x² - 34.
What is Polynomial?A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer.
Here, y = 3x³+x²-5 and z = x²-12
Now,
2 ( y + z ) = 2 ( 3x³+x²-5 + x²-12 )
2 ( y + z ) = 2 ( 3x³ + 2x² - 17 )
2 ( y + z ) = 6x³ + 4x² - 34
Thus, the polynomial which is equivalent to 2 (y + z) is 6x³ + 4x² - 34.

Answers
I got this right, look....
Evidence:
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
The ratios that have a unit rate greater than 1 are:
9/8 miles : 5/6 hours
4 miles : 3(1/3) hours
7 miles : 3/4 hours
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
9/8 miles : 5/6 hours
4 miles : 3(1/3) hours
7 miles : 3/4 hours
The unit rate of each given ratio.
9/8 miles = 5/6 hours
Multiply 6/5 on both sides.
6/5 x 9/8 miles = 1 hour
54/40 miles = 1 hour
27/20 miles = 1 hour
1.35 miles = 1 hour
4 miles = 3(1/3) hours
4 miles = 10/3 hours
Multiply 3/10 on both sides.
3/10 x 4 miles = 1 hour
6/5 miles = 1 hour
1.2 miles - 1 hour
7 miles = 3/4 hours
Multiply 4/3 on both sides.
4/3 x 7 miles = 1 hour
28/3 miles = 1 hour
9.33 miles = 1 hour
We see that,
All of them have unit rates greater than 1.
Thus,
The ratios that have a unit rate greater than 1 are:
9/8 miles : 5/6 hours
4 miles : 3(1/3) hours
7 miles : 3/4 hours

Find a positive coterminal angle less than 360°.
With the given angle -450
Answers
======================================================
Explanation:
The angle -450 is not between 0 and 360. Add on 360 so that we do one full revolution to get -450+360 = -90.
The angle -90 isn't between 0 and 360 either. We repeat the last step by adding on 360 to get -90+360 = 270.
The result 270 is between 0 and 360, so we stop here.
The angle -450 and 270 both point in the same direction. Both point directly south. This is why they are considered coterminal angles.

Answers
Step-by-step explanation:
Given data
let adults be x
and student be y
so
6x+15y= 48-----------1
and
8x+7=38-----------2
solve eqn 1 and 2
6x+15y= 48-----------1X 8
8x+7=38-----------2X 6
48x
+15y= 40
48x+7y= 38
subtract
8y=2
y= 2/8
y= 1/4
y= $0.25
from 8x+7=38
put y= 0.25
8x+7(0.25)=38
8x+1.75= 38
8x=38-1.75
8x=36.25
x=36.25/8
