Use the commutative property of addition to rewrite and simplify the expression.
–10 + 6

Answer: Bella invested $500 in first and $500 in second stock this year.

Step-by-step explanation:

Given: Total principal amount = $1000

Interest = $110

For first year , interest = P x r  , where P= principal , r= rate of interest ( in decimal)

For first bond , interest rate=  15% = 0.15

Let P = x

Interest = 0.15x

For second bond ,  interest rate=  7% = 0.07

Let P = 1000-x

Interest = 0.07(1000-x)=70-0.07x

Now, [tex]0.15x+70-0.07x=110[/tex]

[tex]\Rightarrow\ 0.8x=40\\\\\Rightarrow x=\dfrac{40}{0.08}\\\\\Rightarrow x=500[/tex]

Also, 1000-x = 1000-500=500

Hence, Bella invested $500 in first and $500 in second stock this year.

[tex]8 ^{4} \times 3 {}^{2} [/tex]

Count how many of the same number, since you have four 8's the exponent will be

[tex]8 {}^{4} [/tex]

same applies for 3

Answer:  [tex]8^4 \times 3^2[/tex]

On a keyboard, you can type 8^4*3^2 to indicate the same thing.

===========================================================

Explanation:

There are four copies of 8 being multiplied. Writing [tex]8^4[/tex] is a shorthand way of saying [tex]8 \times 8 \times 8 \times 8[/tex]. The exponent tells us how many copies of the base to multiply out.

Similarly, we have two copies of 3 which means [tex]3 \times 3 = 3^2[/tex]

Answer:

should be 1

Step-by-step explanation:

its constant meaning its an exact slope

and it runs through intersections every 1-1

so the answer is 1 because 1 over 1 in a fraction is still 1

the slope is positive because as you move to the right, the graph goes up

the slope is rise/run = 3/3 = 1

the slope of the line is 1

Infinite amount of solutions

Step-by-step explanation:

Step 1: Write systems of equations

4x - y = 7

3y - 12x = -21

Step 2: Rewrite

-y = 7 - 4x

y = 4x - 7

Step 3: Solve for x

Here we see that we would have infinite amount of solutions.

Answer:

Free throw: 139

2 pointers: 173

3 pts: 123

Step-by-step explanation:

Set x equal to the number of 3pts scored.

Then get 2x-73 from the given number of 2pts relative to 3pts.

Then get 2x-107 from the given number of free throws.

Set up an equation in reference to the number of 3pts and multiply by pts for each type to get:

3x+2(2x-73)+1(2x-107)=854

where 3x is pts from 3pts

2(2x-73) is pts from 2pts

1(2x-107) is pts from free throws.

Simplify to get:

9x-253=854

Solve:

9x=1107

x=123.

Then plug in the number of 3pts scored into the other numbers.

Answer: 1,920ft

Step-by-step explanation:

Answer:

A) 19.2 ft^2

B) 28.9 ft^3

Step-by-step explanation:

Thickness = 8 inches

Assuming the triangular prism is made up of an equilateral triangle hence all sides are equal

lets assume the side = 10 inches  

lets assume the thickness as the height of the prism = 8 inches

Assume length of the rectangle(l) = 5 feet

A) The surface area of the sandwich triangular prism

total surface area = bh + 2ls + lb

                             = 10*8 + 2(5*10) + ( 5 * 10 )

                             = 80 + 100 + 50 = 230 inches = 19.2 ft^2

B ) The volume of filing in cubic feet to the nearest tenth

V = [tex]\frac{1}{4} h \sqrt{-a^4 +2(ab)^2+2(ac)^2-b^4+2(bc)^2-c^4}[/tex]  ------- 1

where : a = b = c = 10 inches

h = 8 inches

input the given values into the equation 1 above

V= 346.41 inches ^3  =  28.9 ft^3

Answer:

[tex]3\frac{12}{13}[/tex]

Step-by-step explanation:

51 / 13 = 3.9231 = 3

51 - (13 x 3) = 12

[tex]3\frac{12}{13}[/tex]

Answer:

3 12/13

Step-by-step explanation:

51/13

13 goes into 51 3 times

13*3 =39

51-39 =12

The 12 goes over the denominator

3 12/13

Answer:

-17

Step-by-step explanation:

The angles are corresponding angles so when the lines are parallel, the lines are equal

3x-12 = 4x+5

Subtract 3x from each side

3x-12 -3x = 4x+5-3x

-12 = x+5

Subtract 5 from each side

-12 -5 = x+5-5

-17 = x

Answer:

-17

Step-by-step explanation:

The two angles that are shown are *corresponding angles* which means they lie in the same spot, just on two different parallel lines. They are congruent angles. Therefore, you should set up an equation to solve for x. Since the two angles are congruent, you should set the expressions equal to each other. 3x-12=4x+5.

Answer:

m = slope  

b = y-intercept  

y = output  

x = input

y = mx + b

y2 - y1 / x2 - x1

Answer:

21

Step-by-step explanation:

The rule for a right triangle is (x^2)x(y^2)=(z^2)

so 20 squared is 400 and 29 squared is 841.

And since the side with the length 29 is the hypotenuse.

It is 400 + [tex]\sqrt{x}[/tex] = 841

841-400=441

the square root of 441 is 21

[tex]\large\underline{\underline{\red{\sf \blue{\longmapsto} Step-by-step\: Explanation:-}}}[/tex]

Given linear equⁿ : x - 2y = 6 .

So , on drawing its graph , the points though which it passes , the coordinates of that particular point will be a solution for this linear equⁿ .

Here , taking the given equⁿ & drawing its graph ,

⇒ x - 2y = 6 .

⇒ x = 6 + 2y .

Now , for a given value of y , x will also have some values .

[tex]\boxed{\begin{tabular}{|c|c|c|}\cline{1-3} \bf x & 6 & 8 \\ \cline{1-3} \bf y & 0 & 1 \\\cline{1-3} \end{tabular}}[/tex]

Now , it's clear that the required order pair which will be solution of the equⁿ can be ( 6 , 0 ) or ( 8 , 1 ) . But since it is a straight line it will have infinite number of solutions .

[ Also Refer to graph in the attachment ]

The ordered pair which will be the solution of the equation can be ( 6, 0 ) or ( 8, 1 ).

Given that,

Equation; [tex]\rm x-2y =6[/tex]

We have to determine,

An ordered pair (x, y) is a solution to the equation?

According to the question,

An ordered pair refers to a number written in a certain order. An ordered pair is used to show the position on a graph,

Where the "x" (horizontal) value is first, and the "y" (vertical) value is second. Also in the co-ordinate system, ordered pair is used to locate a point.

The points through which it passes, the coordinates of that particular point will be a solution for this linear equation.

Here, taking the given equation & drawing its graph,

Equation; [tex]\rm x-2y =6[/tex]

The equation can also be written as,

[tex]\rm x-2y =6\\\\x = 6+2y[/tex]

An ordered pair of the solution is found when substitute y = 0,

[tex]\rm x = 6+2y \\\\x= 6+2(0)\\\\x = 6+0\\\\x = 6[/tex]

And another ordered pair of the solution is found when substitute y = 1,

[tex]\rm x = 6+2y \\\\x= 6+2(1)\\\\x = 6+2\\\\x = 8[/tex]

Hence, the required order pair which will be the solution of the equation can be ( 6, 0 ) or ( 8, 1 ).
