Simplufy 8xy + 6yz + 9xy + 10yz

Answer:

The number is 9 because 9 x 8 = 72. Hope this helps!

The equation to the given phrase is 8x=72 and the unknown number is 9.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Given that, when a number is multiplied by eight, the result is 72.

Let the unknown number be x.

Here, x×8=72

8x=72

x=72/8

x=9

Therefore, the unknown number is 9.

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.

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

collect like terms

m = 18.28 - 7.28

m = 11

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.

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

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.

Step-by-step explanation:

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​

A diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles.
