So if you solve for x using the first equation, you get: x = 5y - 5.
From there you can plug that into the second equation which would give you:
7y-5y+5=-23
Simplifying from that point, you get y = -9.
Now that you have one of the values, you can solve for x by plugging it back into the equation we made (x = 5y - 5) and getting to the answer x = -40.
Solve 54 - 10x s 20 + 7x.

Answer:
2 ≤ x
Step-by-step explanation:
Maybe you want to solve ...
54 -10x ≤ 20 +7x
34 ≤ 17x . . . . . . . . . . . . add 10x-20 to both sides

Step-by-step explanation:
rate of large polygon side to small polygon side is 15:10, or big polygon is 1.5 times greater than small polygon.
so, 12 * 1.5 = 18.
Answer: I think the answer would be 18 or A
Step-by-step explanation: I think because 12+5=17 but 18 is the closest to 17 how I got it is because 15-10=5. It's hard to explain but i think it's A

so my brother asked another question. He asked what is the rectangular room measures 224 square feet. One side of the room is 14 feet long. what is the perimeter of the room? how the question goes. (the rectangular room measures 224 square feet. One side of the room is 14 feet long. what is the perimeter os the room?
Answer:
The perimeter of the room is 60 feet.
Step-by-step explanation:
If the area of the room is 224 square feet, and one side is 14 feet, then the other side is 224/14 feet, or 16 feet.
This gives us the dimensions of the room, 14 x 16.
From this, we can calculate the perimeter, which would be 2(14+16), or 60.
Let me know if this helps!
Answer:
Step-by-step explanation:
The perimeter of the room is 60

Miss Guydan and her friend Alyssa are collecting food for the local food bank. Their goal is to collect 2100 pounds of food. They start with 400 pounds of food donated by a local grocery store. Their goal is to collect 25 pounds of food per day. Write an equation that represent this situation. Define your variables.
Answer: Required equation: 400+25x = 2100
Variable: x = Number of days to donate 2100 pounds.
Step-by-step explanation:
Let x = Number of days.
y = Total pounds of food donated in x days.
Given: Initial amount of food = 400 pounds
Pounds of food donated per day = 25
Total food = Initial amount of food + (Pounds of food donated per day ) (Number of days)
y = 400+25x
Their goal is to collect 2100 pounds.
2100 = 400+25x [Substitute y= 2100]
Required equation: 400+25x = 2100
Variable: x = Number of days.

which graph represents y=3x+2
Step-by-step explanation:
The general form of a straight line is y = mx + c, where m is the line's slope and c is the y-intercept.
For y = 3x + 2, the slope is positive 3 and the y-intercept is 2. The line should rise up and pass through the point (0, 2).
We are between Options B and C.
In Graph B, the line raises by 4 units for every 2 units across. Hence its slope is 4/2 = 2.
In Graph C, the line raises by 3 units for every 1 unit across. Hence its slope is 3/1 = 3.
Since we want 3 as the slope,
The answer is Option C.
The graph C represents y=3x+2

What is the quotient of 5y^3/(5y)^-2
−2 1/4=r−4/5
Help
Plz
Answer:
r=-29/20
Step-by-step explanation:
because
-2 1/4 will be -9/4=r-2/5 now you add 2/5 to both sides
witch means you have to increase the denominator to the greatest common denominator of 4 and 5 witch is 20 multiply the number used to combine with the denominator to get 20 to the numerator so itll be -45/20+16/20 witch will be -29/20 so there fore r=-29/20 or 1 9/20.

Answer:
the equation that has the same solution as the given expression is
m + 7.28 = 18.28
Step-by-step explanation:
Given expression;
0.2m = 2.20
To solve for m, divide both sides by 0.2
[tex]\frac{0.2 m}{0.2} = \frac{2.2}{0.2} \\\\m = 11[/tex]
From the given options, the equation that has the same solution as the given expression is m + 7.28 = 18.28
Solve the equation to confirm as follows;
m + 7.28 = 18.28
