Which best describes the solution to 4 minus 7?
A. Because Negative 4 + (negative 7) is an equivalent expression, the answer is –11.
B. Because 4 + (negative 7) is an equivalent expression, the answer is –3.
C. Because 4 + (negative 7)is an equivalent expression, the answer is –11.
D. Because Negative 4 + (negative 7) is an equivalent expression, the answer is –3.
Answer:
The answer would be "because 4 + (negative 7) is an equivalent expression, the answer is –3".
Step-by-step explanation:
First of all, determine if the answer is going to be positive or negative by seeing the sign of the greater number (that would be 7). So, the answer would be negative. Then do the expression using absolute values; 7-4=3. Now, just add the negative sign before 3 and that's it. You did it! Please rank Brainliest if this helps. Thank you!

12x+5y=34
-6x+5y=3
what do x and y equal
Answer:
Step-by-step explanation:
12x + 5y = 34
6x - 5y = -3
18x = 31
x = 31/18
-6(31/18) + 5y = 3
-31/3 + 5y = 9/3
5y = 40/3
15y = 40
y = 40/15
y = 8/3
(31/18, 8/3)

Sadie finished her math test in sixteen minutes less than three times the amount of time it took her friend Laura to finish. If their combined time was 1 hour and 8 minutes (68 minutes), how long did Sadie take?
Answer:
47 minutes
Step-by-step explanation:
Let k be the amount of time Laura took.
Then Sadie would be 3k-16. So
k+3k-16=68
4k=84
k=21 minutes for Laura
Sadie=3(21)-16=47 minutes ......
In ΔEFG, g = 6.7 inches, e = 5.9 inches and ∠F=70°. Find the length of f, to the nearest 10th of an inch.
Step-by-step explanation:
Using cosine rule,
f² = g² + e² - 2(g)(e)(cosF) = 6.7² + 5.9² - 2(6.7)(5.9)(cos70°)
= 52.6598 in²
Hence f = 7.3 in.
The length of f in the triangle EFG is 7.3 inches.
What is cosine rule?The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them. The law of cosine states that: a² = b² + c² − 2bc·cosA.
Given that, in ΔEFG, g = 6.7 inches, e = 5.9 inches and ∠F=70°.
By using cosine rule in ΔEFG, we get
f² = e² + g² − 2eg·cos70°
= 5.9²+6.7²-2×5.9×6.7×0.342
= 79.7-27.03852
f² = 52.66148
f = 7.3 inches
Therefore, the length of f is 7.3 inches.

Explain how to write a composite function to find
the area of the region at time t.
Answer:
[tex]A(t) = \pi (0.5 + 2t)^2[/tex]
Step-by-step explanation:
Given
[tex]r(t) = 0.5 + 2t[/tex]
[tex]A(r) = \pi r^2[/tex]
Required
Determine composite function to find A in terms of t
The interpretation of this question is to determine A(t) and this is solved as follows:
Because:
[tex]r(t) = 0.5 + 2t[/tex]
And we want to eliminate r in [tex]A(r) = \pi r^2[/tex]
We have to substitute 0.5 + 2t for r in [tex]A(r) = \pi r^2[/tex]
[tex]A(r) = \pi r^2[/tex] becomes
[tex]A(t) = \pi (0.5 + 2t)^2[/tex]
The solution can be solved further, but it is best left in this form:
[tex]A(t) = \pi (0.5 + 2t)^2[/tex]
A farmer owns a total of 10 acres of land. The land is separated into 4 2/3 equally sized sections. How many acres are in each section? Write your answer as a mixed number in simplest form.
Answer:
2 1/7 arces are in each section
Step-by-step explanation:
4 2/3 is same as 14/3
So we want to divide 10 acres into 14/3 equally sized sections
Mathematically, that will be;
10/14/3
= 10/14 * 3 = 15/7 = 2 1/7 arces

(NEED HELP ASAP!!) You are saving for a skateboard. Your aunt gives you $45 to start, and you save $3 each
week. The expression 45 + 3 w gives the amount of money you save after w weeks. How
much will you have after six weeks?
Answer:
$63
Step-by-step explanation:
You have the constant, $45. You then receive $3 each week. This can be written at $45 + $3w, where w is the number of weeks. So in this case, we need to find out how much money you will have after 6 weeks. We just need to plug in 6 weeks into the equation. The new equation will now be $45 + $3(6).
3 times 6 is $18.
$45 + $18 will give you a final answer of $63.
Answer:
The answer is $171
Step-by-step explanation:
There 7 days in 1 week so 7 times 6 which is 42 then you do 42 times 3 which is 126 then 126 plus 45 is 171 there's your answer
How much would 5 chicken and noodle meals and 1 order of chicken and potatoes be if the tax on 1 meal is $0.18. Chicken noodle costs $7.35 and chicken and potatoes costs $6.25.
Answer:$44.08
Step-by-step explanation:
$7.35 x 5 = $36.75
$0.18 x 5 = $0.90
$0.90 + $36.75 = $37.65
$37.65 + $6.25 + $0.18 = $44.08
What is the area of the irregular figure?
_____ m2
Answer:
936 is the correct nswer he he he he eh
Step-by-step explanation:
The total area of the given figure will be 936 square meters.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.
Given that the dimensions of the given figure are,
Width of the first rectangle = 24 m
Length of the first rectangle = 18 + 12 = 30 m
Width of the second rectangle = 42 - 24 = 18 m
Length of the second rectangle = 12 m
Total area = Area of first rectangle + Area of the second rectangle
Total area = ( 24 x 30 ) + ( 18 x 12 )
Total area = 720 + 216
Total area = 936 square meters
Therefore, the total area of the given figure will be 936 square meters.
