Answer:6

Step-by-step explanation:

Subtract the three 1 point shots

Subtract the four 3 point shots

You are left with 12, and you split that in 2 because they're 2 point shots.

Answer:

3 and 1

Step-by-step explanation:

To make this equation true you have to fill in the blank spots so x is 3

So I simply multiplied 3 times x which is 3x+ blank is 10

if I want x to be 3 then I fill in the blank for 1

now I do additive inverse to get the x by itself

subtract 1 on both sides

the equation is now 3x=9

Divide 3 in each sides and x=3

Answer:

1x + 7 = 10

-4x + 22 = 10

Step-by-step explanation:

Equations

We are given the following expression:

__x + __ = 10

Where the spaces must be filled with any value that makes x=3 the solution to the equation.

Let's call a and b the variables to fill up the spaces:

ax + b = 10

For x=3, the following equation must stand:

3a + b = 10

Any combination of a and b that makes true the above equation will solve the problem. Let's solve for b:

b = 10 - 3a

Make a=1, thus b = 10 - 3 = 7

So the equation:

1x + 7 = 10

Has the solution x=3

For a = -4, b = 10+12 = 22

Another combination is:

-4x + 22 = 10

Answer:

2=16 3=24 spot on her shell

Step-by-step explanation:

The number of squares appeared on Ally's shell at the age of 2 is  64 and the age of 3 is 512.

"A square is a two-dimensional plane figure with four equal sides and all the four angles are equal to 90 degrees. The properties of rectangle are somewhat similar to a square, but the difference between the two is, a rectangle has only its opposite sides equal. Therefore, a rectangle is called a square only if all its four sides are of equal length."

Given,

When the turtle was 1 year old the number of squares = 8

When the turtle was 2 year old the number of squares = 8 * 8 = 64

When the turtle was 3 year old the number of squares = 64 * 8 = 512

Hence, square at age 1 = 8, squares at age 2 = 64, squares at age 3 = 512.

Answer:

-125

Step-by-step explanation:

add 50 and 75 =125 make in negative

The additional expression for the change in Dennis's score after two rounds is (-50) + (-75) and the value of change is -125.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that:

During a game, Dennis lost 50 points in the first round and then lost 75 more points in the second round.

Let x be the change in the points:

The points are 50 and 65

The expression can be written as:

= (-50) + (-75)

= -125

The negative sign needs to write before the numbers because Dennis lost 50 points and 75 points in the game.

Thus, the additional expression for the change in Dennis's score after two rounds is (-50) + (-75) and the value of change is -125.

Answer:

The answer is below

Step-by-step explanation:

m∠lon = m∠2 (vertical opposite angles are equal)

m∠lon = m∠1 (corresponding angles are equal).

Therefore; m∠2 = m∠1 (substitution property)

3x + 25 = 7x + 5

Subtracting 5 and 3x from both sides of the equation:

3x + 25 - 5 - 3x = 7x + 5 - 5 - 3x

4x = 20

dividing through by 4:

4x / 4 = 20 / 4

x = 5

Given that:

m∠3 = -2x + 70

substituting x = 5:

m∠3 = -2(5) + 70 = 60

m∠3 = 60°

Therefore:

m∠4 + m∠2 + m∠3 = 180° (substitution)

(155 - 3x) + (7x + 5) + (-2x + 70) = 180

(-3x + 7x - 2x) + (155 + 5 + 70) = 180

2x + 230 = 180

2x = -50

x = -25

Therefore; m∠3 = -2x + 70 = -2(-25) + 70 = 50 + 70

m∠3 = 120°

Step-by-step explanation:

Answer:

x=4

Step-by-step explanation:

Correct

Answer:

No solution

Step-by-step explanation:

y = x + 4

y = x - 4

The slopes are the same  (1), but the y intercepts are different ( 4, -4)

That means the lines are parallel, so they will not intersect.  That means the system does not have a solution.

Answer:

Ok so the information you gave is :-

Slope = 1/4

Y-intercept = 3

So first you will graph the y-intercept. So the y-intercept is 3 or (0, 3). Then you will plot the slope which is 1/4. If you know that slope = rise/run. So you will go 1 unit up and 4 units to the right. Hope this helps, thank you and if you need help then I am here.

Answer:

-3x²+17x-20

Step-by-step explanation:

When you apply the distributive property (which you did correctly), you simply multiply each number or variable in which you have to distribute it to (which again you wrote correctly) and then you add them all together.

(3x)(-x)=-3x²

+

(3x)(4)=12x

(-5)(-x)=5x

(-5)(4)=-20

Add those and you will get your answer. Hope this helped :)

Answer:

Natalie is 12 years and Fred is 28 years

Step-by-step explanation:

lets assume Natalie's age is X and Fred's age is Y

From the first sentence: X+Y = 40

From the second sentence: Y + 4X = 76

lets rearrange the equations

X+Y =40 ....... equation 1

4X+Y=76........ equation 2

To solve both equations, we will have to look for a way to eliminate one of the unknown to leave us with one unknown. since there are two +Y in both equations, we can subtract both equations to eliminate Y. Please note that whatever you do to one of the unknown in this equations applies to all other numbers & alphabets

So: 1. X - 4X = -3X

2. Y - Y = 0

3. 40 -76 = -36

writing the equation as one will be -3X = -36

X = 12

Put X = 12 into any of the equation

By putting X as 12 into equation 1 : 12 + Y = 40

Y = 40 -12 =28

Recall that Natalie is X and Fred is Y

Therefore Natalie is 12 years and Fred is 28 years

be

To crosscheck put in the gotten answers into the equations

X+Y =40 ....... 12 + 28 = 40

4X+Y=76........ 4(12) + 28 = 76

Answer:

x = 25

Step-by-step explanation:

it's an isosceles triangle so base angles are the same

3x - 30 = 45

Add 30 on both sides

3x = 75

divide both sides by 3

x = 25

Output       2       3/2       3        5/2       4         7/2

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

Let 'y' be the output and 'x' be the input.

Given the rule "Divide by 4, then add 2." Complete the following table. Then the function is given as,

y = (x / 4) + 2

At x = 0, then we have

y = (0 / 4) + 2 = 2

At x = 2, then we have

y = (2 / 4) + 2 = 3/2

At x = 4, then we have

y = (4 / 4) + 2 = 3

At x = 0, then we have

y = (0 / 4) + 2 = 2

At x = 0, then we have

y = (0 / 4) + 2 = 2

At x = 6, then we have

y = (6 / 4) + 2 = 5/2

At x = 8, then we have

y = (8 / 4) + 2 = 4

At x = 10, then we have

y = (10 / 4) + 2 = 7/2
