Mr martins math test which is worth 100 points has 29 problems. Each problem is worth either 5 points or 2 points.
Let x be the number of questions worth 5 points and let y be the number of questions worth 2 points.
x+y=29, 5x+2y=100

Answer:

m = 36

n = 3

Step-by-step explanation:

y varies inversely with x can be written as y ≅ 1/x.  As x goes up, y will go down.  We need a factor, N, to account for how much change occurs with each step.  There needs to be a factor involved, F, to account for how much change occurs with each step.  

Calculate the factor by using one of the known points.  I'll use (8,9):

y = F/x

9 = F/8

F = 72

The relation becomes y = 72/x.  Check this on the other given point, (12,6):

y = 72/x

6 = 72/12  ?   YES

Now use y = 72/x to find the two missing points, (m,2) and (24,n):

(m,2) 2 = 72/m,     m = 36

(24,n)  n = 72/24;   n = 3

Answer:

x = 12

Step-by-step explanation:

42 + 4x = 90 ( as it is right angle)

transpose to find x

4x = 90 - 42

4x = 48

x = 48/4

x = 12

Answer:

x=12

Step-by-step explanation:

90-42=48 48/4=12

Answer:

53.85%

Step-by-step explanation:

75-48.75= 26.25

26.25/48.75x100= 53.8461538462 Round 53.85%

Check Answer:

48.75 x 53.85%=26.251875 Round 26.25

48.75 + 26.25=75

Hence, the correct answer is 53.85%.

You can use the fact that equivalent equations are such that one equation can be obtained by performing some operations(which doesn't break equality) on the other equation and vice versa.

The equivalent equation to [tex]x + 4 = 64[/tex] is [tex]x = 60[/tex]

Equivalent equations are such that one equation can be obtained by performing some operations(which doesn't break equality) on the other equation and vice versa.

The given equation is

[tex]x + 4 = 64[/tex]

Subtracting 4 from both sides, we get

[tex]x + 4 - 4 = 64 - 4\\x = 60[/tex]

Thus, one equivalent equation to the given equation is [tex]x = 60[/tex]

The equivalent equation to [tex]x + 4 = 64[/tex] is [tex]x = 60[/tex]

Answer:

$289,169.84 (to the nearest cent)

Step-by-step explanation:

Compound interest is based on the principal amount and the interest that accumulates on it in every period.

Compound Interest = P (1 + r)^n

where P = principal amount, r = annual interest rate (as a decimal), n = term, in years​

So for this problem:

P = 185000

r = 1.4 ÷ 100 = 0.015

n = 30

Therefore,  

Compound Interest = P (1 + r)^n

                                = 185000 x (1 + 0.015)^30

                                = 185000 x (1.015)^30

                                = 289169.8408...

                                = $289,169.84 (to the nearest cent)

Step-by-step explanation:

just subtract 400.8-185.2 to get width

Answer:

15.2

Step-by-step explanation:

We know the formula to find the perimeter of a rectangle is 2(w + l) or 2w + 2l (in this case we'll use 2w + 2l). We are given the length as 185.2. Next, we multiply 185.2 by 2 (or add twice) to get 370.4. Then, we subtract 370.4 from 400.8 to get 30.4. Lastly, we split 30.4 in half to get 15.2 meters.

Answer:

System of equation : 14x+23y = 213 and y = x-2

The cost of regular tickets is $7 and the cost of tickets with donation is $5.

Step-by-step explanation:

Let regular ticket's cost be x and tickets with donation's cost be y.

14x+23y = 213

y = x-2

Now,

14x+23y = 213

or, 14x+23(x-2) = 213

or, 14x + 23x - 46 = 213

or, 37x = 259

so, x = 7

again,

y = x-2

or, y = 7-2

so, y = 5

Answer:

n = 135/7

Step-by-step explanation:

2 x long side + short side = 75

substitute measures                 ⇒ 2(1.5n + 3) + (0.5n + 1.5) = 75

multiply out brackets               ⇒ 3n + 6 + 0.5n + 1.5 = 75

gather like terms                      ⇒ 3n + 0.5 n + 6 + 1.5 = 75

combine like terms                  ⇒ 3.5n + 7.5 = 75

subtract 7.5 from both sides   ⇒ 3.5n = 67.5

divide both sides by 3.5          ⇒ n = 135/7

Answer:

vertex = (- 1, 1 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

y = x² + 2x + 2 ← is in standard form

with a = 1 and b = 2 , then

x = - [tex]\frac{2}{2}[/tex] = - 1

substitute x = - 1 into the equation for y- coordinate of vertex

y = (- 1)² + 2(- 1) + 2 = 1 - 2 + 2 = 1

vertex = (- 1, 1 )

Answer:

A) 11(0.65)+c=10

Step-by-step explanation:

Step 1: Calculate the price of 11 oranges at $0.65 each.

11 × 0.65 = $7.15

Step 2: Consider the constraint: if Maribel only has a $10 bill, we have to deduct $7.15 from $10 to find our answer:

$10.00 - $7.15 = $2.85

Step 3: Write an equation based on our solution:

C = 10-0.65x ; Where:  

* 10- indicates that we start with $10, and subtract from there.
* C is the amount of change per purchase.
* X is the number of oranges a customer buys.

Answers:

1. The customer receives $2.85 in change.
2. Given a case where a customer pays with one 10-dollar bill, their purchase amount can be calculated with C = 10-0.65x
