Ben wrestles in the 132 to 138-pound weight class. If he currently weighs 133 pounds, how much weight can he gain if he wishes to stay in the same class?
Answer:
X is less than or equal to 5
Step-by-step explanation:
I cant do the less than or equal to sign so I wrote it in words. Hope this helps :)
Answer:
5 pounds
Step-by-step explanation:
Let x represent Ben's weight gain.
[tex]138 \geq 133 + x\\[/tex]
Subtract 133 from both sides
[tex]5 \geq x[/tex]
Therefore, Ben can't gain more than 5 points if he wishes to stay in the same weight class.

The equation of the line in this graph is y = ____x + ____.
Answer:
y=3/2x+3
Step-by-step explanation:
The equation is in y=mx+b format. m is the slope, or steepness of the line, while b is the y intercept (where the line crosses with the y axis).
The given line shows the y intercept; it's 3.
To find the slope, use this equation: y2-y1/x2-x1
Pick any two points and plug them into the equation. For example, use (0,3) (y intercept) and (-2, 0) (x intercept.)
now,
3-0/0-(-2)
3/2
the slope is 3/2.
Now, the line is
y=3/2x+3.

what is the slope of the line below
Answer:
m=1/2
Step-by-step explanation:
When finding the slope of a line on a graph, I like to count the steps up/down and to the side between two of the line's points. For this line, we can see that it has points at (2,-1) and (4,0). To get from (2,-1) to (4,0), you need to count
"up 1, over 2"
1/2
Therefore, the slope is 1/2.

The given question is incomplete
Here are some letters and what they represent. All costs are in dollars.
m represents the cost of a main dish.
n represents the number of side dishes.
s represents the cost of a side dish.
t represents the total cost of a meal.
Discuss with a partner: What does each equation mean in this situation? a. a. m = 7.50
b. m = s + 4.50
c . ns = 6
d. m + ns = t
2. Write a new equation that could be true in this situation.
Answer:
t = 3m -n(s+1)
Step-by-step explanation:
Using the information we can describe the value of each letters
using a and b
we have m = 7.50 and m = s + 4.507.50 = s + 4.50
s = 3
substitute s in c, we get
ns = 6n = 6/3 = 2using equation d we have
m + ns = t7.50 + 6 = tt = 13.50so we an equation using the above data
t +ns = 3m - n
t = 3m -n(s+1)

Hurryyy !!! Lincoln Glass pays it workers overtime if they work on weekends or
holidays. Overtime is 1/2 times the usual hourly pay. If Tim was
earning $8.25 an hour, how much would he get for 1 hour of
overtime? For 8 hours of overtime?
Step-by-step explanation:
since overtime is 1/2 the usual pay which is 8.25 or 8 1/4 then its 8 1/4 (divided) by 1/2 which is equal to 4.125 or 4 1/8 so: in 1 hour the workers get paid 4 1/8 dollars and in 8 hours its 8 x 4 1/8 which is equal to 33
really hope this helps :) good luck
#Answer:
1 hour = $4.13 (rounded) . 1 hour = $4.125 (not rounded)
8 hours = $33.04 (rounded) 8 hours = $33 (not rounded)

A table showing Number, Value, and Total Value. The first row shows Nickels, with the entries, n, 0.05, and 0.05 n. The second row shows Quarters, with the entries 36 minus n, 0.25, and 0.25 left-parenthesis 36 minus n right-parenthesis. The last row has Total, with the entries 36, blank, 6.
Alexandra has 36 coins valued at $6.00. She has only nickels and quarters. Which equation can be used to solve for the number of nickels, n?
0.05n + 0.25(36 – n) = 6
0.05n + 0.25(36 – n) = 36
n + 0.05 = 0.05n
n + (36 – n) = 36
Answer:
a- 0.05n + 0.25(36 – n) = 6
Step-by-step explanation:
i just did it on edg
The value of each coin (Nickels and Quarters) determines their number in a money sum
The correct option that gives the equation that can be used to solve for the number of nickels, n, is option;
0.05·n + 0.25·(36 - n) = 6
Reason:
The given equation can be presented as follows;
[tex]\begin{array}{|c|c|c|c|}&\mathbf{Number}&\mathbf{Value}&\mathbf{Total \ value}\\&&&\\Nickels&n&0.05&0.05 \cdot n\\Quarters&36 - n&0.25 & 0.25 \cdot(36 - n)\\&&&\\\mathbf{Total}&36&&6\end{array}\right][/tex]
From the above table, we have;
0.05·n + 0.25·(36 - n) = 6
Solving the above equation gives;
0.05·n + 9 - 0.25·n = 6
-0.2·n = 6 - 9 = -3
[tex]n = \dfrac{3}{0.2} = 15[/tex]
Therefore;
The equation that can be used to solve for the number of nickels, n, is; 0.05·n + 0.25·(36 - n) = 6

What is the determinant of A = [ -2 2 b 0 3 a 0 0 -5 ]
Answer:
30
Step-by-step explanation:
To find the determinant of a 3x3 matrix, you can use this method. (See picture.)
Start with the first number in the top row, and block off the row and column. A 2x2 matrix will be left. Find the determinant of this 2x2 matrix, and multiply it by the number in the top row.
Repeat for the other two numbers in the top row. Add the first result, subtract the second, and add the third.
det A = -2 [(3)(-5) − (a)(0)] − 2 [(0)(-5) − (a)(0)] + b [(0)(0) − (3)(0)]
det A = -2 (3)(-5) − 0 + 0
det A = 30
In 56 years, Kevin will be 9 times as old as he is right now.
Answer – 7 years old
SOLVINGS
Let Kevin’s present age be ‘x’
In 56 years, Kevin’s age will be x + 56
In 56 years, Kevin’s age will be 9x
Therefore, x + 56 = 9x
Solving for x
x + 56 = 9x
9x – x = 56
8x = 56
x = 56/8
x = 7
Kevin is 7 years old right now.
