Answer:

35

Step-by-step explanation:

In such cases where there are two minuses, you join them and turn it into a plus sign. So therefore...

= 10 - ( -25 )

= 10 + 25

= 35

Answer:

x = 3

Step-by-step explanation:

Subtract 8x from both sides.

3x+4−8x=8x−11−8x

−5x+4=−11

Subtract 4 from both sides.

−5x+4−4=−11−4

−5x=−15

Divide both sides by -5.

−5x

−5

=

−15

−5

x=3

Answer:

x=4

Step-by-step explanation:

4(3+2x)+2=46

12+8x+2=46

12+8x=44

8x=32

x=4

Answer:

4

Step-by-step explanation:

You need to start with the 2x inside the parenthesis

If you put 4 in place of x you get 8

8+3=11

then because there isnt any sign between 4 and the parenthesis you multiply

4x11=44

then its easy

44+2=46

Answer:

y=13

Step-by-step explanation:

AD is identical to DC so if half of AC is AD which is 8, AC must be 16

2y - 10 = 16

2y = 26

y = 13

Answer:

The sum will be positive because when using KCF ( keep change flip) the problem becomes 75-57 therefore the answer will be positive 18. hope this helps

Answer:

675 miles

Step-by-step explanation:

450 : 2 = 225

10 gallons of gas = 225 miles

225 * 3 = 675

30 miles will get you 675 miles

Answer:

y=x-1

Step-by-step explanation:

The equation is currently in standard form which is a+b=y and slope-intercept is y=mx+b where m is the slope and b is the y-intercept. To change the form we must move the terms around using Properties of Equality.

First, subtract 1 from both sides

x-y-1=1-1

x-y-1=0

Then, add y to both sides

x-y-1+y=0+y

x-1=y

So that is the equation in slope-intercept form with a slope of 1 and a y-intercept of -1.

Answer:

y=x-1

Step-by-step explanation:

It is y=x-1 because first when we do ANYTHING first. We leave the y on the left side of the equation, since the slope y=mx+b has the y always on the left side. So we subtract x from both sides and we get -y=-x+1. We are NOT DONE yet, so after this, we divide both sides by -1. Why? This is because you cannot have a negative y. Dividing both sides by -1 you finally get y=x-1. If this is trouble some to read, I will also put how to solve the problem down below. :)

Let's solve for y.

x−y=1

Step 1: Add -x to both sides.

x−y=1+−x

−x

−y=−x+1

Step 2: Divide both sides by -1.

−y/ −1 = −x+1 /−1

y=x−1

Answer:

y=x−1

Answer:

Step-by-step explanation:

step 1 Address input parameters & values.

Input parameters & values:

The fraction number = 315/79

step 2 Write it as a decimal

315/79 = 3.9873

3.9873 is the decimal representation for 315/79

For Percentage Conversion :

step 1 To represent 3.9873 in percentage, write 3.9873 as a fraction

Fraction = 3.9873/1

step 2 multiply 100 to both numerator & denominator

(3.9873 x 100)/(1 x 100) = 398.73/100

398.73% is the percentage representation for 315/79

Answer:

probaly about ten or 11 five four times is 20 and they are 22

Step-by-step explanation:

5 + 5 +5 +5=20

then you would do 2 x 4 since five is four times

2 x 4 = 8

so i would round up

Step-by-step explanation:

let eqn be y = mx + b.

3y = x - 15

y = 1/3x - 5

perpendicular means product of grad = -1

hence m = -3.

sun (8, 0):

8 = -3(0) + b

b = 8

therefore, equation if the line is y = -3x + 8

Step-by-step explanation: The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.
