Simplify the expression. 1.7 – 2.7 – 1.34 + 4.9 – 1.48
please explain I'm lost
Answer:
Step-by-step explanation:
1.7 - 2.7 - 1.34 + 4.9 - 1.48
First we can group the positive and negative numbers
1.7 + 4.9 - 2.7 - 1.34 - 1.48
add the positive numbers then add the negative numbers
1.7 + 4.9 becomes 6.6
-2.7 - 1.34 - 1.48 becomes - 5.52
Now add both the answers
6.6 + (- 5.52) = 1.08
Hope this helps

for a new neighborhood, 100 acres of land will be split into 10 lots. how many acres of land will each lot have?
Each lot will have 10 acres of land.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To find out how many acres of land each lot will have, you can divide the total amount of land (100 acres) by the number of lots (10).
So,
= 100 acres ÷ 10 lots
= 10 acres per lot
Therefore,
Each lot will have 10 acres of land.

22 382
i put the top one but appearnly its wrong it probs me being stupid i dont know please help 10 points avabile
Answer:
682 is the biggest number but if it is talking about the two numbers added then it is 19 and 682
Edit: If there is supposed to be a comma in-between the two pairs of numbers then the answer would be 32,665. I didn't think they could have been commas at first but if they are then 32,665 is the answer.
Step-by-step explanation:
682 is bigger than all the others. 19 + 682 is bigger than all the other paired ones.

Which of the following numbers is a composite number?
OA) 13
OB) 31
OC) 49
OD) 67
Step-by-step explanation:
First you will need to know what a composite number is.
A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.
see pic below
I think it would be OC) 49
(Because that is a composite number.)

What is the equation of the line that passes through the point (8,1) and has a slope of -3/4 PLEASE HELP
Answer:
y = -3/4x + 7
Step-by-step explanation:
Given: m = -3/4
y = mx + b
(1) = -3/4(8) + b
1 = -6 + b
b = 7
Use m and b to form equation of line:
y = mx + b
y = -3/4x + 7
Answer: y = 7 over 10 x -8
Step-by-step explanation:The point we are given (0,−8) is the y-intercept (c). The clue for this is that the x-value is 0, which means the point lies on the y-axis.

For the first equation 6v+38≤ -4
The answer would be v≤-7
and for the second equation 2(v+3)≥-2
the answer would be v≥-4
Step-by-step explanation:
6v+38≤ -4
Subtract 38 from both sides
6v+38-38≤-4-38
Simplify
6v≤-42
Divide both sides by 6
6v/6≤-42/6
Simplify
v≤-7
SAME THING FOR THE OTHER
2(v+3)≥-2
Divide both sides by 2
2(v+3)/2≥-2/2
Simplify
v+3≥-1
Subtract 3 from both sides
v+3-3≥-1-3
And finally, simplify
v≥-4

The sum of five consecutive even integers is 220. Find the middle value of the five consecutive integers.
Answer:
44Step-by-step explanation:
If we have odd number of consecutive numbers increasing by the same value (2) then the middle value of them is their mean:
220:5 = 44
Of course you can find them to be sure:
Consecutive even integers increase by 2.
So if 2x is the smallest of them (x is an integer), then the numbers are:
2x, 2x+2, 2x+4, 2x+6, 2x+8
So their sum: 10x+20
10x + 20 = 220 ⇒ 10x = 200 ⇒ 2x = 40
So the numbers are: 40, 42, 44, 46, 48
Answer:
44

You have $65.00 in birthday money and want to buy some CDs and a DVD.
Suppose a DVD cost $15.00 and a CD cost $12.00. Write an inequality to find
out how many CDs you can buy along with one DVD. Solve the inequality.
Answer:
1 dvd and 4 cds
Step-by-step explanation:
If you have $65.00 and 1 dvd costs $15.00 that leaves you with $50.00 and each CD costs $12.00 just multiply by 12s until you get to 50 or close so there you can buy 4 CDs and have 2$ left.

Answer:
Step-by-step explanation:
L = 3*w + 1 Given
P = 2*(L + w) Formula for Perimeter. Substitute for L
P = 2*(3w + 1 + w) Combine
P = 2*(4w + 1)
P = 58 Given
58 = 8w + 2 Remove the brackets
58 - 2 = 8w Subtract 2
56 = 8*w Divide by 8
56/8 = w
7 = w
================
Find L
L = 3*w + 1
L = 3*7 + 1
L = 22
================
Check
2L + 2W = 58
2*22 + 2*7 =? 58
44 + 14 = ? 58
58 = 58
The answer checks.

What will the value of angle #2 be? Show your work.
Find g(3), given that g is a linear function with g(1)=-2 and g(4)=8
Answer:
14/3
Step-by-step explanation:
linear equation slope passing (1,-2), (4,8)= 8-(-2) / 4-1 = 10/3
g=10/3 x +b, substitute (1,-2) to solve b
-2=10/3 (1) +b, b=-16/3
thus, g=10/3 x - 16/3
when x=3, g=14/3
