Which number is a solution of the inequality 7x-5>-2? ( by the way that sign is supposed to be a less than or equal to)
A.-3
B.-1
C.0
D.1
Final answer:
The correct answer to the inequality 7x - 5 ≥ -2 is D. 1, since 1 is greater than 3/7 and thus satisfies the inequality.
Explanation:
To solve the inequality 7x - 5 ≥ -2, we need to isolate x. Follow these steps:
Add 5 to both sides of the inequality to cancel out the -5 on the left: 7x ≥ 3.
Divide both sides by 7 to solve for x: x ≥ 3/7.
Now we need to determine which of the provided options is a solution to the inequality. We have:
A. -3 (which is less than 3/7)
B. -1 (which is also less than 3/7)
C. 0 (which is again, less than 3/7)
D. 1 (which is greater than 3/7, making it a solution to the inequality)
The correct answer is D. 1 because it satisfies the given inequality.

Deshawn fuels 2 yachts and 6 barges. Each boat gets 126 gallons of fuel. To find how much fuel he needs for all the boats, deshawn first findsthe number of boats, then he uses an algorithm to multiply. Which are the three partial products deshawn could add to find the final product?
Deshawn, who fuels 2 yachts and 6 barges each with 126 gallons of fuel, can find the total fuel needed by calculating and summing three partial products; 800, 160 and 48, derived from breaking down the multiplication of 8 (total boats) and 126 (gallons per boat). The combined total is 1008 gallons.
Explanation:Deshawn needs to fuel 2 yachts and 6 barges, making a total of 8 boats. Each boat requires 126 gallons of fuel. Deshawn's algorithm for determining the total fuel required involves finding three partial products to multiply.
If we break down the multiplication of 8 (total boats) and 126 (gallons per boat), into three parts we get:
Multiplying 8 by 100 to get 800. Multiplying 8 by 20 (part of the 26 in 126) to get 160. Finally, multiplying 8 by 6 (the units digit in 126) to get 48.
These are the three partial products that Deshawn could add together (800 + 160 +48) to find the total fuel needed which is 1008 gallons.

What number can you add to π to get a rational number?
PLEASE HELP thank you :P
Solution:
As we know π is an irrational number.The value of π is non terminating non repeating.
As we all know , π =[tex]\frac{\text{Circumference of circle}}{\text{Diameter}}[/tex],
The fact is still we are getting an irrational number.
As , 0 is a rational number.
So, The number which when added to π, to get a rational number is (-π).

Four friends purchase 18.4 pounds of peaches. The peaches cost $1.75 per pound. The friends share the cost of the peaches equally. How do I do this!!!!?????????
Answer:
Cost per friend = 8.05 $
Step-by-step explanation:
Four friends purchase 18.4 pounds of peaches.
The peaches cost $1.75 per pound.
Total cost of peach = Total pounds x Cost of peach per pound
Total cost of peach = 18.4 x 1.75 = 32.2 $
Number of friends dividing the cost equally = 4
[tex]\texttt{Cost per friend = }\frac{\texttt{Total cost of peach}}{\texttt{Number of friends dividing the cost equally}}\\\\\texttt{Cost per friend = }\frac{32.2}{4}=8.05\$[/tex]
Cost per friend = 8.05 $

for fhg find the measure of the smallest angle <hfg if m<ghf equals 92 degrees and m<hgf equals 72 degrees
The correct answer is:
16°.
Explanation:
The sum of the measures of the angles of a triangle is 180°. The two angles we have are 92° and 72°; together, these total to
92+72 = 164
This leaves us
180-164 = 16° for the remaining angle of the triangle.
To find the measure of the smallest angle
To find the measure of the smallest angle <hfg in triangle FHG, we need to use the fact that the sum of the angles in a triangle is 180 degrees. We are given that m<ghf = 92 degrees and m<hgf = 72 degrees. To find <hfg, subtract the measures of the other two angles from 180: 180 - 92 - 72 = 16 degrees. Therefore, the measure of the smallest angle <hfg is 16 degrees.
