Jenny made 520 walnut biscuits. This is 40% of the total number of biscuits that she made. How many biscuits did she make in all?

Answer:

5x

Step-by-step explanation:

subtract 4x fromboth sides

4x-10=2x

-4x     -4x

divide both sides by -2

-10=-2x

-10/-2=-2x/-2

5=x

Answer: 42 gallons

Step-by-step explanation:

1,260/180 = 7

Per 180 mile = 6 gallon

7x6=42

Answer:

Y = 2/5z-6/5w

Step-by-step explanation:

6W + 5y = 2z

1. Subtract 6W from both sides

2. 5y = 2z-6W

3. Divide both sides by 5

4. y = 2/5z-6/5W

Answer:

im not 100 percent sure but i think its x=71

Answer:

Step-by-step explanation:

The problem with this question would be resolved in a New York second if people learned what an exterior angle was. x is an exterior angle. Exterior angles have their own set of properties. One of them is that they are the sum of the two interior angles not supplementary to the given exterior angle.

In the diagram above the supplement to x has no marking. It is not an exterior angle. x is the exterior angle.

A triangle has Interior sums of 180o. Everyone here seems to understand that. What is not understood is the properties of x and the other two exterior angles. Exterior angles polygons of any number of sides have exterior angles that add up to 360 degrees. The 360 degrees does not indicate that they are not circles.

So the answer to this question is that x = 64 + 45 = 109. If you put anything else in, you will get it wrong.

This question checks to see if you understand the difference between an exterior angle and an interior angle. 71 is not the answer. It is not even the second best answer. It is just the third interior angle.

Answer:

x = 3

y = 18

Step-by-step explanation:

you replace y with 6x

x + 6x = 21

combine like terms

7x = 21

divide both sides by seven

x = 3

then you plyg 3 into the other equation

y = 6(3)

y= 18

Answer:

x=3

y=18

Step-by-step explanation:

x+y=21..........equation 1

or,x=21-y......equation 2

y=6x.......equation3

substituting the value of x in equation 3

y=6(21-y)

or,y=126-6y

or,7y=126

y=18

again,substituting the value of y in equation 2

x=21-y

or,x=21-18

x=3

x=3,y=18

B) the plant grows 0,45 inches per day

C) the height and the number of days are highly related

D) 5.55

Am in a rush sorry lol don’t have time to explain

Answer:

The plant grew 9 more inches since last year.

Step-by-step explanation:

75% of 12 is 9 and the initial plant growth was 12 inches.

So, the plant grew 9 more inches since last year.

The plant is now 21 inches.

Answer:

9

Step-by-step explanation:

Divide 12 by 4 to get 25% = 3

25% x 3 = 75%

3 x 3 = 9

Answer: 1/7

Step-by-step explanation: The points create a posotive line so the answer has to be posotive. You then have to look at the rise over run. (0,1) is 1 unit higher than (-7,0) and the run is the ditance between the 2 x exvalues. 7. Rise/run = 1/7
