Answer:

7 quaters and 19 dimes

Step-by-step explanation:

Let say x the numbers of quaters,

2*x+5 the numbers of dimes

In cents,: 25*x+10*(2x+5)=365

25x+20x+50=365

45x=365-50

45x=315

x=7

Number of quaters: 7

Number of dimes: 2*7+5=19

Proof:

7*25+10*19=365

Answer:

8 GB

Step-by-step explanation:

Cost = sum of fees 1, 2, and 3

C = 56 + .95g +  .08t

so

68 = 56 + .95g + .08(55)

68 = 56 + .95g + .08(55)

68 = 56 + .95g + 4.4

68 - 56 - 4.4 = .95g

7.6 = .95 g

7.6/.95 = g

8 = g

Answer:

∠DAB = 68

Step-by-step explanation:

∠DAB we need to find this

∠DAB = ∠C (vertically opposite angles are equal)

∠DAB = 68

Answer:

[tex]5.72[/tex]g of fiber is contained in the black beans.

Step-by-step explanation:

Given:

No.of. ounces[tex]=4.4[/tex]

Each ounce contains [tex]1.3[/tex]g of fiber

To calculate the fiber contained in the black beans

Total Fiber = No.of. ounces × Fiber contained in each ounce

[tex]=4.4[/tex] × [tex]1.3[/tex]

[tex]=5.72[/tex]g

Therefore, fiber contained in the black beans is [tex]5.72[/tex]g.

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

4x + y = 1 ( subtract 4x from both sides )

y = - 4x + 1 ← in slope- intercept form

with slope m = - 4 and y- intercept c = 1

Answer:

-6

Step-by-step explanation:

Hope I understand your "f(x) = 12 over the quantity of 4 x + 2" correctly

f(x) = 12 / 4x +2

Now so they want a f(-1), as u can see they substituted the x for - 1, therefor do that the same to the right side

f(-1) = 12/ 4(-1) + 2

f(-1) = 12 / - 4+2

= 12/ - 2

= - 6

Answer:

B

Step-by-step explanation:

4 (x - 7) - 2 (x + 1) = 10

I Kg = 1000 g

3 Kg = 3000 Kg

Step-by-step explanation:

Kg - Hg - Dag - g

1 Kg - 10 Hg - 100 Dag - 1000 g

So, 1 Kg = 1000 g

3 Kg = 3(1000)g = 3000 g

Answer:

Step-by-step explanation:

The balls - multiples of 3 are:

The probability of a multiple of 3 is:

30% probability is in the range 0%-50% so this event is unlikely

Total multiples=3

[tex]\\ \sf\longmapsto P(3)=\dfrac{Multiples\:of\:3}{Total \:balls}[/tex]

[tex]\\ \sf\longmapsto P(3)=\dfrac{3}{10}[/tex]

[tex]\\ \sf\longmapsto P(3)=30\%[/tex]

So it is unlikely to happen.

Answer:

x = 2

Step-by-step explanation:

5-2x = -4x+9

5+(-2x+4x) = (-4x+4x)+9      [Add 4x to each side to get ride of 4x on the right]

5+2x = 9

(5-5)+2x = (9-5)     [subtract 5 from both sides to get rid of 5 on the left]

2x = 4

2x/2 = 4/2     [Divide each side by 2 to get x alone]

x=2

The solution to the equation 5 - 2x = -4x + 9 is x = 2.

Here, we have,

To solve the equation 5 - 2x = -4x + 9 step by step, we will combine like terms and isolate the variable x.

Here's how:

Start by simplifying both sides of the equation by combining like terms:

5 - 2x = -4x + 9

The left side has no like terms to combine, so we move to the right side:

-2x + 4x = 9 - 5

Simplifying further:

2x = 4

Now, we want to isolate the variable x.

To do that, we need to get rid of the coefficient 2 that is multiplied by x.

We can achieve this by dividing both sides of the equation by 2:

(2x)/2 = 4/2

Simplifying further:

x = 2

We have found the solution for the variable x.

Therefore, the solution to the equation 5 - 2x = -4x + 9 is x = 2.

Answer:

number is 3

Step-by-step explanation:

let the number be n then the product of 3 and the number is 3n , so

16 = 7 + 3n ( subtract 7 from both sides )

9 = 3n ( divide both sides by 3 )

3 = n

That is the number is 3

Answer:x=11

65.25x + 1063.50= 1781.25

To solve this equation, subtract the rental cost of the bus to get $717.75.

Now the equation should be 65.25x= 717.75

Divide both sides by 65.25, and you should get that x = 11. That’s your finally answer!

Answer:

Step-by-step explanation:

The expanded form of 79 is 70+ 9. To apply the distributive property you rewrite the problem 3(70 + 9) which is the same as (3x70) + (3x9). Next do the multiplication 3x70= 210 + 3x9= 27

Next add the sums: 210 + 27 = 237.

by using the formula, we can find :

T7 = [7⁴ - 6(7)³ +23(7)² - 18(7) +24] / 24 =

(2401 - 2058 + 1127 - 126 +24) / 24 =

1368/ 24 = 57

T8 = [8⁴-6(8)³+23(8)²-18(8)+24]/24 =

(4096-3072+1472-144+24)/24 =

2376/ 24 = 99
