Solve for x. 5x+4=9
Can you help me out?

Answer:

a = -9

Step-by-step explanation:

8 - a = 17

8 -17 = a

-9 = a

Answer:

-9

Step-by-step explanation:

subtract 8 from both sides. divide -1 by both sides it gives you -9. When put into the equation the two negatives make a positive and you add 8 + 9 which gives u 17.

I'll solve one from each kind

Q1)

6 = a/4 + 2 (mutiply both sides)

24 = a + 8 (move the terms)

-a = 8 - 24 (calculate)

-a = 8 - 16 (change the signs)

a = 16

Q8)

2( 2 + 5) = -2 (divide both sides)

n + 5 = -1 (move the constant to the right)

n = -1 - 5 (calculate)

n= -6

Q3)

9x - 7 = 7 (cancel equal terms)

9x = 0 (divide both sides)

x = 0

To convert to slope-intercept form, we need to get the y by itself.

First add 3x to both sides to get 3y = 3x + 9.

I put the x term first because in slope-intercept form or y = mx + b form,

the x term will always come before the constant term.

Now divide both sides by 3 to get y = x + 3.

Answer:

y = x + 3

Step-by-step explanation:

-3x + 3y = 9

3y = 9 - 3x

/3     /3   /3

y = x + 3

3 burgers....... 2 fries.... 17 /×2

2 burgers...... 4 fries..... 18

=>

6 burgers...... 4 fries..... 34

2 burgers...... 4 fries..... 18

____________________

6 - 2 =4 burgers

34 - 18 =16 $

=>16 :4 =4 $ one burger

17 - 3×4 =5 $ cost 2 order of fries

5 :2 =2,5 $one order of fries

Final price = price x (1 + sales tax)

Final price = 45 x 1.055 = $47.48

Step-by-step explanation:

Add three to both sides 2x=5+3

Simplify  5+35+3  to  88. 2x=8

Divide both sides by 22.  x= 8/2

Simplify 8/2 to 4

x=4

Answer:

y = -5/3 x + 11/3

Step-by-step explanation:

5x +3y = 11

3y = 11 - 5x

y = -5/3 x + 11/3

Answer:

If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable

Answer:

3.8 × 10^{1}

Step-by-step explanation:

Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b.

Follow the steps below to see how 38 is written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 38

New Number: 3.8

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 3 . 8

Decimal Count: 1

There are 1 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 3.8

b = 1

Now the whole thing:

3.8 x 10^{1}

Step 4

Check work:

10^{1} = 10 x 3.8 = 38

Answer:

I only

Step-by-step explanation:

1 - 2x <= 8

-2x <= 7

x >= -7/2

x >= -3.5

-2 is a solution

Answer: I only

Answer:

answer is 1 only

as 1-2 (-2) < 8

1+ 4 < 8

5 < 8 satisfies the given equation

if the ab ratio is 1:4 wouldnt i need a diagram for that?

Answer:

m∠B= 67

m∠C= 23

Step-by-step explanation:

okay so same thing we did before except they will equal 90 not 180

B= 3(c)+2

c+b=90

c+3(c)+2=90

4c+2=90

4c=92

c=23

now input them! or subtract!

90-23=67

m∠C=23

m∠B=67

Answer:

4x + 8y = 30

Step-by-step explanation:

Cost of raisins = $4 per pounds

Cost of walnuts = $8 per pounds

Total spent on both ingredients = $30

Let

Pounds of raisins = x

Pounds of walnuts = y

Diego's equation can be represented by

PxQx + PyQy = 30

Where,

Px = price of raisins

Qx = Quantity of raisins (pounds)

Py = price of walnuts

Qy = Quantity of walnuts (pounds)

PxQx + PyQy = 30

4x + 8y = 30

Answer:

91 miles

Step-by-step explanation:

14 x 6.5 = 91

Answer:

x=10

Step-by-step explanation:

(2x)/(x-5)=4

first you multiply the denominator on both sides

2x=4(x-5)

then multiply

2x=4x-20

then move all the x variables to one side and the constants to the other with subtraction and addition

20=2x

divide and you get x=10

you can plug this in to check your work and you'll see: (2(10))/(10-5)=4 or 20/5=4 which you know is true

Answer:

Step-by-step explanation:

m<3 = 43 degrees

add 43 degrees and 43 degrees and the answer is 86. and since everything equals 180 degrees, 180 - 86 = 94. since there are 2 side needed to be solved divide 94/2 = 47

so 47 degrees for <2 and 47 degrees for <4

to check my work just add up all the sides

47 degrees for <2, 47 degrees for <4, 43 degrees for <1, 43 degrees for <3

47 + 47+ 43+ 43= 180 degrees

hope this helps:)
