What is [tex]13 \leq 24[/tex]
Make a explanation to this... Do not copy, or on g.oogle...
Maybe you can show proof how you got the answer?
Thanks~
Answer:
13 < 24.
Step-by-step explanation:
This is asking if 13 is greater than or equal to 24.
13 does not equal 24.
Thus, 13 is greater than 24.
We point the arrow tip at the 13 because it is being shot by the 24. (I made that up but it actually works)
Jim needs to rent a car. A rental company charges $21 per day to rent a car plus $0.80 per mile driven. How many miles can he drive in a day if he wants to spent AT MOST $82. Write an inequality. Show work Or explain how to solve it and then give a solution as an inequality.
Answer:
Inequality: .80x +21 ≤ 82
Answer: 76.25 miles in total
Step-by-step explanation:
Hi,
An inequality to represent this is .80x +21 ≤ 82
(.80 is the cost per mile and x is the number of miles driven. 21 is the fee that must be paid no matter what and the 82 is the total cost they can pay. We use the ≤ sign to say they can spend less than or equal to 82. The phrase "at most" means we can use the ≤ sign).
Now we solve...
.80x + 21 ≤ 82
Subtract 21 on both sides...
.80x ≤ 61
Now, divide by .80 on both sides...
x ≤ 76.25
He can drive up to 76.25 miles in total
Hope this helps :)
Sandy’s mom bought 4 lbs of apples and paid $8.76. What was the cost per pound? *
A: $2.09/lb
B: $2.19/lb
C: $1.99/lb
D: $0.45/lb
Answer:
B. $2.19/lb
Step-by-step explanation:
the equation 8.76÷4 will give us the cost per pound
8.76÷4= 2.19
this is because I used the normal equation to find the unit rate which in this case is the price per pound

3(y+25)=−15
what is y
Answer:
y = -30
Step-by-step explanation:
3(y+25)=−15
3y +75 = -15
subtract 75 from each side of the equation:
3y = -90
y = -90/3 = -30
proof:
substituting -30 for y:
3(-30 + 25) = -15
-90 + 75 = -15
-15 = -15
Answer: The answer to your question is y= -30
The volume of a rectangular prism is 50 5/8 cubic inches.
The dimensions are given below.
What is the missing value in the table?
Answer:i think b
hope this helps
Step-by-step explanation:
The width of the rectangular prism is W = 4 1/2 inches
What is the volume of a prism?A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.
The volume of a prism is the product of its base area and height
Volume of Prism = B x h
where B = base area of prism
h = height of prism
Given data ,
Let the volume of the prism be V = 50 5/8 inches³
Now , the length of the prism is L = 5 inches
And , the height of the prism be H = 2 1/4 inches
Let the width of the prism be W = W
where Volume of Prism = B x h = L x W x H
On simplifying , we get
50 5/8 inches³ = 5 x 2 1/4 x ( W )
50.625 = 11.25W
Divide by 11.25 on both sides , we get
W = 4.5 inches
Hence , the width of the rectangular prism is W = 4.5 inches

Answer:
answer of q no.2
-3 and 12
Explanation:Suppose two numbers are x and y
smaller number = x
larger number = y
Given that,
The difference of two numbers is 15
Equation 1
y - x = 15
Five times the smaller is the same as 9 less than twice the larger.
Equation 2
5x = 9 - 2y
Solve them
-x = 15 - y
x = y -15
put value of x in equation 2
5(y - 15) = 9 - 2y
-75 + 5y = 9 - 2y
-75 - 9 = -2y - 5y
-84 = -7y
y = 84/7
y = 12
x = 12 - 15
x = -3

Chloe is drinking 3/5 cup of water every 6 minutes. How many cups will they drink in 2 hours?
Answer:
12 cups
Step-by-step explanation:
One of the easiest ways to solve this problem is to first turn the fraction into a decimal. 3/5=0.6
The second step is to see how much water Chloe drinks in an hour. Since there are 60 minutes in an hour and 6 times 10 is 60, we do 0.6 times 10 to see how much water Chloe drinks in one hour. 0.6x10=6
The third and final step is to double 6. We do this because 6 is how many cups of water Chloe drinks in one hour, but we need to find two. 6x2=12.
Therefore, Chloe would drink 12 cups of water in 2 hours.
Answer:
Step-by-step explanation:
12 cups. You have to divide 120 by 6, then you divide that answer (20) by 3/5, which is 0.6 in decimal form, your answer should be 12 cups of water.
