1. 3x-(5x-9)= 7-4(x+1)​

Answer:

The team scored 25 2-point goals and 5 3-point goals

Step-by-step explanation:

Here, we are interested in calculating the number of 3 points and 2 points goals scored by the team

let the number of two point goals be x while the number of three point goals be y

The total goal number is 30;

Hence;

x + y = 30 ••••••(i)

Also, the total point is 65

point of two points goals is 2 * x = 2x

points of three point goal is 3 * y = 3y

Adding both;

2x + 3y = 65 ••••••(ii)

So we have two equations to solve simultaneously.

From 1, x = 30 -y

Now substitute this into ii

2(30-y) + 3y = 65

60 -2y + 3y = 65

y = 65 -60

y = 5

x = 30 - y

x = 30-5 = 25

Answer: C

Step-by-step explanation:

30 km/s x 60 = 1800 (1 minute)

1800 x 60 = 10800 (1 hour)

Answer:

C.  108,000 km

Step-by-step explanation:

use distance = velocity x time

30  km x 3600 sec  x  1 hr

      sec         1 hr

= 108,000 km

Answer:

T(n) = 1800 + 58n

Step-by-step explanation:

Rent reception = $1800

Charge per person = $58

Number of person who attend reception = n

Total cost = fixed cost + variable cost

Fixed cost = 1800

Variable cost = 58n

Total cost = T(n)

Total cost = fixed cost + variable cost

T(n) = 1800 + 58n

Answer:

A: Infinite

B: One

C: No Solution

Step-by-step explanation:

The sides are the same. This means that the equation has infinite solutions.

The equation has one solution.

[tex]2x+7=2x\\\\2x-2x+7=2x-2x\\\\\boxed{7\neq 0}[/tex]

The final result is a contradiction. The equation has no solution.

Answer:

1. C

2. A

Step-by-step explanation:

Step 1: Write equation

3x - 1 = 7

3x = 8

Step 2: Use 1st equation and solve

3x = 8

x = 8/3

Step 3: Use 2nd equation and solve

3x = 8

x = 8/3

Both equations have equivalent solutions and the 2nd equation is the simplified version of the 1st.

Answer:

[tex]BC=26[/tex]

Step-by-step explanation:

Start with:

[tex]AB+BC=AC[/tex]

Since [tex]B[/tex] is the midpoint, we also know that:

[tex]AB=BC[/tex]

Knowing this, we can use a system of equations and substitute [tex]AB[/tex] for [tex]BC[/tex] in the equation we started with:

[tex]AB+AB=AC[/tex]

Let's identify our values:

[tex]AB=3x-1\\AC=8x-20[/tex]

Substitute:

[tex]3x-1+3x-1=8x-20[/tex]

Combine like terms:

[tex]6x-2=8x-20[/tex]

Add [tex]20[/tex] to both sides of the equation:

[tex]6x+18=8x[/tex]

Subtract [tex]6x[/tex] from both sides of the equation:

[tex]18=2x[/tex]

Divide by the coefficient of [tex]x[/tex], which is [tex]2.[/tex]

[tex]x=9[/tex]

Substitute [tex]9[/tex] into [tex]3x-1[/tex]

[tex]3(9)-1[/tex]

Solve:

[tex]AB=26[/tex]

Remember that [tex]AB=BC[/tex], thus:

[tex]BC=26[/tex]

The first thing he has to do is take that "minus" sign through the parentheses containing the second polynomial. Some students find it helpful to put a " 1 " in front of the parentheses, to help them keep track of the minus sign. Here's what the subtraction looks like, when working horizontally.

The correct option is Option C: the missing value is 12.

In directly proportionality, if one quantity increases then the other quantity also increases. if one quantity decreases then other quantity also decreases.

x ∝ y

⇒ x= ky

where k is proportionality constant.

Here the value x1, y1 is given by

x1=8

y1=6

as x1 is directly proportional to y1.

x1 = ky1

⇒8=6k

⇒k= 8/6

⇒k =4/3

If x3= 24 then x3 =ky3

⇒24=(4/3)y3

⇒y3= 24/(4/3)= 18 which is true from the table

Then given in the question x2=16

As x2 is directly proportional to y2.

x2 ∝ y2

⇒ x2 =ky2

where k= 4/3

⇒ 16 = (4/3)y2

⇒ y2= 16/(4/3)

⇒y2= 16*3/4

⇒y2= 12

The correct option is Option C: the missing value is 12.

Answer:

GH = 17

Step-by-step explanation:

Given that H is the midpoint of segment GI, and GH = 5x + 2, HI = 9x - 10, GH is congruent to HI. This implies GH = HI.

Therefore:

[tex] GH = HI [/tex], which will give us the following equation:

[tex] 5x + 2 = 9x - 10 [/tex]

Solve for x

[tex] 5x + 2 - 9x = 9x - 10 - 9x [/tex] (subtracting 9x from each side)

[tex] -4x + 2 = -10 [/tex]

[tex] -4x + 2 - 2 = -10 - 2 [/tex] (subtracting 2 from each side)

[tex] -4x = -12 [/tex]

[tex] \frac{-4x}{-4} = \frac{-12}{-4} [/tex] (dividing both sides by -4)

[tex] x = 3 [/tex]

GH = 5x + 2

Plug in the value of x

GH = 5(3) + 2 = 15 + 2

GH = 17

Answer:

Vertically opposite angles are angles that are formed opposite of each other when two lines intersect, and they are always equal.

Thus, Angle PBH is 118 degrees.

Answer:

696

Step-by-step explanation:

[tex]\frac{m}{8} = 87[/tex]

First I would multiply each side by 8 to find what M is (because if you multiple m/8 by 8 the 8s will cancel out).

[tex]m=87*8\\m = 696[/tex]

Because any number divided by 1 would just be itself, 696/1 is just 696.

Answer: m/1= 7.125 or 7.1 (rounded)

Step-by-step explanation:

if m/8=57 then m/1 multiplied by 8 would be 57 . so you do the opposite and divide 57 by 8.
