OMG PLEASE HELP QUICK 7TH GRADE LEVEL

Answer:

16/14= 8/7 = lauren/ cara

8x+7x= 1200

15x= 1200

x= 1200/15

x=80

lauren= 8x= 8(80)= 640

cara= 7x= 7(80)= 560

Step-by-step explanation:

Answer:

Step-by-step explanation:

Okay, I'm assuming you want us to figure out how much the hat costs.

To start off, let's figure out how much the gloves cost after the discount. 35 / 100= 0.3. We multiply that by 70%, since that is how much of the price is going to be left over after deducting 30%. We get $24.50.

So;

$44.80 of the total bill - $24.50=$20.30.

So we now know the hat cost $20.30.

Answer:

x = 4

Step-by-step explanation:

7x + 16/11 = 4

11 x 7x + 16/11 = 4 x 11

7x + 16 = 44

7x + 16 - 16 = 44 - 16

7x = 28

7x/7 = 28/7

x = 4

Check:

7x + 16/11 = 4

7(4) + 16/11 = 4

28 + 16/11 = 4

44/11 = 4

4 = 4 (note that this number is not the answer, just to check if each side is balanced, the actual answer is 4)

Answer:

x = 4

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define

[tex]\displaystyle \frac{7x + 16}{11} = 4[/tex]

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 4 does indeed equal 4.

∴ x = 4 is the solution to the equation.

Answer:

16 rides

Step-by-step explanation:

If he has $12 in total and each ride costs 75 cents, you can divide 12 by .75 to find how many rides he can go on.

12/0.75 = 16

Answer:

2x^9 x

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "x3"   was replaced by   "x^3".  

STEP  1 :

Multiplying exponential expressions :

1.1    x4 multiplied by x3 = x(4 + 3) = x7

The Equation at the end of step  1 :

 ((2x7 • x) • x) • y

STEP  2:  Final result :

 2x^9 y

Answer:

how to do this

Step-by-step explanation:

i need it

Answer:

yes

Step-by-step explanation:

it is a rational number

Answer:

Step-by-step explanation:

To solve this, we would use the formula for calculating simple interest which is:

Interest = PRT

Then, we will slot in the values given which will be:

84 = P × 3% × 7

84 = P × 0.03 × 7

84 = 0.21P

P = 84/0.21

P = $400

The Principal is $400

Answer:

100th term = -1485

Step-by-step explanation:

[tex]t_{n} = a + (n - 1)d[/tex]

n = number of terms

= 100

a = first term

= 5

d = difference

= second term - first term

= 2 - 5

= -3

substitute the values into the formula

[tex]t_{100} = 5(100 - 1)( - 3)[/tex]

[tex]t_{100} = 5(99)( - 3)[/tex]

[tex]t_{100} = 495( - 3)[/tex]

[tex]t_{100} = - 1485[/tex]

Answer:

0.2 is the answer...........

Answer:

50%

Step-by-step explanation:

Total students = 12 + 18 + 6 = 36

Seventh-graders = 18

18/36*100 = 50%

Answer:

Step-by-step explanation:

12 are 6th graders

18 are 7th graders

6 are eight graders

total=36

7th graders are 50%

18........................?%

36.........................100

18*100/36=50

Step-by-step explanation:

4+5+6=1000

1000/15

4 . 5. 6= 266.4 . 333. 399

9514 1404 393

Answer:

  266 2/3 : 333 1/3 : 400

Step-by-step explanation:

The total of ratio units is 4+5+6 = 15, so the fraction of 1000 that each portion represents is ...

  4/15 : 5/15 : 6/15 = 4/15 : 1/3 : 2/5

Multiplying 1000 by these fractions gives ...

  1000(4/15) : 1000/3 : 1000(2/5)

  = 266 2/3 : 333 1/3 : 400

Answer:

x=22 y= 46

Step-by-step explanation:

2-24 2-48

Answer:

Equations are :---

[tex]3x - 2y = 24............... (i) \\ x + 2y = 48..................(ii)[/tex]

By adding the both equations we get,

[tex](3x - 2y) + (x + 2y) = 24 + 48 \\ 4x = 72 \\ x = \frac{72}{4} \\ \boxed{ x = 18} \\ [/tex]

Putting the value of x in equation (ii) we get

[tex]18 + 2y = 48 \\ 2y = 48 - 18 \\ 2y = 30 \\ y = \frac{30}{2} \\ \boxed{y = 15}[/tex]

Answer:

  B)  Dilations increase angle measures.

Step-by-step explanation:

Dilations have no effect on angle measures, but they uniformly change the size and spacing of line segments. They are a non-rigid transformation that leaves geometric figures similar to the original.

The false statement is B.

Answer:

The minimum number of teachers needed for this trip is 18.

Step-by-step explanation:

The slope for this is 5/2. So the equation is y = (5/2)x. We know the y is 45 students. So we do division. In the end, we get x = 18 teachers.

Answer:

(1/3)(9x+27) > x + 33

multiply out the 1/3

3x + 9 > x + 33

subtract x and 9 from both sides

2x > 24

x > 12

D) because you dont include the 12

Step-by-step explanation:

Right angled triangle ✅

90° + 3x + 2x = 180° {sum}

5x = 90

x = 90/5 = 18

x = 18

acute angle : 3x = 3 × 18 = 54°

2x = 2 × 18 = 36°

Answer:

lemonade = 11

Step-by-step explanation:

let p = pink lemonade

let t = sweet tea

create a system of equations -- one with quantity, one with associate costs

p + t = 21      

2.5p + 4t = 67.5

substitution method:  let t = 21 - p

2.5p + 4(21 - p) = 67.5

2.5p + 84 - 4p = 67.5

-1.5 p = -16.5

p = 11

t = 21 - 11

t = 10
