Answer:

Total number of marbles is:

First question:

Second question:

Third question:

Answer:

y = 0

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−5(6+7y)=−5(6+y)

(−5) (6) + (−5) (7y) = (−5) (6) + (−5) (y) (Distribute)

−30 + − 35y = −30 + −5y

−35y − 30 = −5y −30

Step 2: Add 5y to both sides.

−35y − 30 + 5y = −5y −30 + 5y

−30y −30 = −30

Step 3: Add 30 to both sides.

−30y − 30 + 30 = −30 + 30

−30y = 0

Step 4: Divide both sides by -30.

−30y /−30  =  0 /−30

Answer:

b= 2

Step-by-step explanation:

x=2

y=-2

slope= -2

y=mx+b

-2= -2(2) + b

-2= -4 +b

-2+4= b

2= b

Answer:

2=b through the slope -2=-2(2)+b

Step-by-step explanation:

Answer:

a(n) = -16b + (n - 1)(3b)

Step-by-step explanation:

First term is -6b.

Common difference is 3b; each new term is equal to the previous one, plus 3b.

Formula for this arithmetic sequence is

a(n) = -16b + (n - 1)(3b)

Answer:

B=80

Step-by-step explanation:

B is the same answer as the number on the other side

Answer:

A = 19.135 yd²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 4.3 and h = 8.9 , then

A = 0.5 × 4.3 × 8.9 = 19.135 yd²

Step-by-step explanation:

f(x)=x²+x

f(3)=3²+3

Answer:

3a. yes

3b. y= 75x

3c. 600 mi

3d. 10 inches

Step-by-step explanation:

3a: if you divide the y by the x, you'd get 75 everytime, meaning it's proportional.

3b: y would equal the amount of inches multiplied by 75, so y=75x

3c: you can use the equation and substitute the x for 8, so y=75(8), giving you 600 miles

3d: you can also use the equation in reverse, if the actual miles is 750, then this is your y, so it would look like 750=75x and to solve you'd divide, 750/75, giving you 10 inches

Answer:

315

Step-by-step explanation:

819 miles/13 hours = 63 miles per hour

63 x 5 = 315

Answer:

Step-by-step explanation:

Girls Basketball = x

Girls Soccer = x + 3

Total = 51

x + x + 3 = 51        Combine like terms

2x + 3 = 51            Subtract 3 from both sides

     - 3   - 3

2x = 48                 Divide by 2

2x/2 = 48/2

x = 24

The basketball team has 24 players

The soccer team has       27

C

Step-by-step explanation:

Answer:

-5 < x ⩽ 1

Step-by-step explanation:

Given the compount inequality

–2 < x + 3 ⩽ 4

Subtract 3 from all the sides

-2-3 < x+ 3 - 3 ⩽ 4 - 3

-5 < x ⩽ 1

This can be expressed as;

-5 <x and x ⩽ 1

x > -5 and x ⩽ 1

Hence the reqiures set of values of x are values from -4 to 1

S ={-4, -3, -2, -1, 0, 1}

Answer:

5/11, 20/11

Step-by-step explanation:

a − 3b = −5

-3b = -a - 5

b = 1/3a + 5/3

3a + 2(1/3a + 5/3) = 5

3a + 2/3a + 10/3 = 5

11/3a + 10/3 = 5

11/3a = 5/3

a = 5/11

a - 3b = -5

5/11 - 3b = -5

-3b = -60/11

b = 20/11

Answer:

126.109,63 m

Step-by-step explanation:

Por conveniencia, todas las unidades se convierten a m

1000 m = 1 km

100 m = 1hm

10m = 1 presa

1 m = 1 m

10dm = 1m

100 cm = 1 m

1000 mm = 1 m

1m- (5dm3cm) (2hm4m) + 35dam (3hm6dam) + (8dam5m) (2m5dm6cm) -85cm

= 1m- (5/10 +3/100) (2 * 100 + 4m) + 35 * 10 (3 * 100 + 6 * 10) + (8 * 10 + 5m) (2m + 5/10 + 6/100 ) -85/100

= 1 m- (0.5 +0.03) (200 + 4m) +350 (300 +60) + (80 + 5m) (2m + 0.5 + 0.06) -85/100

= 1 m- (0,53) (204 m) +350 (360) + (85 m) (2,56) -85/100

= 1 m- (108,12 m) +126000+ (217,6) - 0,85

= 126.109,63 m

For convenience all units are converted to m

1000m = 1km

100 m= 1hm

10m = 1 dam

1m= 1m

10dm= 1m

100 cm= 1 m

1000 mm= 1m

1m-(5dm3cm) (2hm4m)+35dam (3hm6dam)+(8dam5m) (2m5dm6cm)-85cm

= 1m-(5/10 +3/100) (2*100 +4m)+35*10 (3*100 +6*10)+(8*10+5m) (2m+5/10+6/100)-85/100

= 1m-(0.5 +0.03) (200 +4m)+350 (300 +60)+(80+5m) (2m+0.5+0.06)-85/100

= 1m-(0.53) (204m)+350 (360)+(85m) (2.56)-85/100

= 1m-(108.12m)+126000+(217.6)- 0.85

= 126,109.63 m

Answer:

  10

Step-by-step explanation:

The distance formula is useful.

  d = √((x2 -x1)^2 +(y2 -y1)^2)

  d = √((7 -1)^2 +(12 -4)^2) = √(6^2 +8^2) = √(36 +64) = √100

  d = 10

The distance between P and Q is 10.

You may recognize the run : rise ratio of 6 : 8 = 3 : 4. This suggests a 3-4-5 right triangle with a scale factor of 2. If you're familiar with that Pythagorean triple, you can write down the answer as soon as you see the rise and run numbers.
