Answer:

80

Step-by-step explanation:

(x + 45) - (1.5x - 12) = 17

x + 45 - 1.5x + 12 = 17

-0.5x+57=17

-0.5x=-40

-40/-0.5=80

Answer:

Step-by-step explanation:

The distributive property of multiplication over addition tells you a factor outside parentheses will multiply each term inside parentheses. That fact is used to expand the given expression. In general, ...

  a(b +c) = ab +ac

  2(-a +5) = 2(-a) +2(5)

__

The multiplicative identity element is the value that can multiply any expression and leave it unchanged. It is 1. That is, multiplying anything by 1 leaves it unchanged.

This fact is generally used to cancel factors common to a numerator and denominator: (2x)/2 = x(2/2) = x(1) = x, for example. It is also used extensively in units conversion.

__

The associative property of addition lets you group the terms of a sum any way you like. It lets you move parentheses at will. (Beware subtraction.)

Here, the parentheses are moved from grouping the first two terms to instead grouping the last two terms.

Additional comment

These are part of the vocabulary of math. Even if you don't remember the specific definitions, it is essential to remember what these properties allow. Making use of them is the way that expressions are simplified and equations are solved.

Answer:

Step-by-step explanation:

Distributive Property of Multiplication

The distributive property of multiplication is to distribute or multiply one term by all terms.

Identity Property of Multiplication

Identity property is to multiply by 1. This doesn't change the value, so it keeps the value, identity, the same.

Associative Property of Addition

The associative property is to group terms differently, preferably like terms. 2 and 5 are like terms, because they are integers.

Answer:

D. 11/24

Step-by-step explanation:

→ [tex]\frac{5}{6} -\frac{3}{8}[/tex]

→ [tex]\frac{40-18}{48}[/tex]

→ [tex]\frac{22}{48}[/tex]

→ [tex]\frac{11}{24}[/tex]

Answer:

D is the answer

Step-by-step explanation:

[tex]\frac{5}{6} - \frac{3}{8} \\[/tex]

find a common factor between 6 and 8, thats 24.

(multiply the first fraction by 4, second by 3, both numerator and denominator)

Becomes:

[tex]\frac{20}{24} - \frac{9}{24}[/tex]

Then subtract the numerators, keeping the denominators the same:

20 - 9 = 11;  

So the answer is:

[tex]\frac{11}{24}[/tex]

Answer:

3 solutions

Step-by-step explanation:

x = 0; x = 2; x = -6

As we are given with an equation as follows :

[tex]{:\implies \quad \sf x^{2}(x+2)(x+6)=0}[/tex]

As product of these three factors is equal . So , any of these factor can be 0 as product is 0 only when one of the expressions which are multiplied is 0. So , 3 cases arises as follows ;

[tex]{:\implies \quad \sf x^{2}=0}[/tex]

On raising ½ power to both sides we have ;

[tex]{:\implies \quad \sf x=\pm \: 0}[/tex]

Now , as +0 and -0 have no difference in them . So , it's simply 0

[tex]{:\implies \quad \sf So\quad x=0}[/tex]

[tex]{:\implies \quad \sf x+2=0}[/tex]

[tex]{:\implies \quad \sf So\quad x=-2}[/tex]

[tex]{:\implies \quad \sf x+6=0}[/tex]

[tex]{:\implies \quad \sf So\quad x=-6}[/tex]

[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{Hence \:\: x\in \{0,\: -6,\: -2\}}}}[/tex]

Answer:

.3390 or just .339

Step-by-step explanation:

Answer:

c ≈ 16.55cm ; ∠A = 65 degrees ; ∠B = 25 degrees

Step-by-step explanation:

Because of the Pythagorean theorem, we can solve for c.

This theorem states: a^2 + b^2 = c^2

Since there can only be 180 degrees in a triangle, angle C must be our largest angle. This means that side c is our hypotenuse (the longest side).

Using all of this information, we can say that 15^2 + 7^2 = c^2.

Simplifying that equation, we get that 274 = c^2.

In order to find c, we must square root both sides, and we find that c is about 16.55 cm long.

Using SOHCAHTOA, we know that the tan(∠B)=[tex]\frac{7}{15}[/tex]. Therefore, the arctan ([tex]\frac{7}{15}[/tex]) = ∠B.

Once you find that ∠B is about 25 degrees, you can add ∠B and ∠C together and subtract that from 180 to find ∠A.

∠A = 65 degrees.

Answer: 9sqrt(3)

Step-by-step explanation:

First, we can prime factorize 243.

243 = 3^5

Therefore we are computing the square root of 3^5

3^5 = 3^4 * 3^1; 3^4 = (3^2)^2

Therefore, sqrt(3^5) = sqrt((3^2)^2))*3^1)

= 3^2*sqrt(3)

= 9sqrt(3)

Answer:

Step-by-step explanation:

I will use the formula for finding the slope of a line.

rise/run = y2 - y1/x2 - x1

3 - r/2 - -5

We will subtract 2 from -5. 2 - -5 = 7

Since the slope is 2, and 2 - -5 = 7, then 3 - r = 7x2 = 14.

3 - 14 = -11

r = -11

Answer:

Michaela gets 3.45$ back.

Step-by-step explanation:

1 carton of eggs = 1.58$

she buys 2, so 2 times 1.58= 3.16$

1 pound of turkey = 6.99$

she buys 4.15 pounds, so 4.15 times 6.99= 29.01$

she buys a jar of jam for 4.38$

4.38 + 3.16 + 29.01 = 36.55$

4 times 10= 40

40 - 36.55 = 3.45$

Answer:

  $3.10

Step-by-step explanation:

The cost of the goods Michaela buys is ...

  2 cartons eggs at $1.58 per carton = $3.16

  4 1/5 pounds turkey at $6.99 per pound = $29.36

  1 jar of jam at $4.38 per jar = $4.38

The total is then ...

  $3.16 +29.36 +4.38 = $36.90

Four $10 bills will be $40, so the change is ...

  $40 -36.90 = $3.10

Michaela will receive $3.10 in change.

Additional comment

We know that Brainly often mangles mixed numbers, so we have assumed that "415" is intended to be 4 1/5. If it is intended to be 4.15 pounds, then the price of the turkey, and the change, will be different by about $0.35. Michaela's change will increase by that amount.

Answer:

a=10 and c=20

Step-by-step explanation:

This is a system of equations. I will solve using the substitution method.

a+c=30

12a+8c=280

Solving for a:

a+c-c=30-c

a=30-c

Substituting a into the second equation:

12(30-c)+8c=280

360-12c+8c=280

360-4c=280

-4c=-80

c=20

Substituting into the original equation:

a+20=30

a+20-20=30-20

a=10

To prove this answer is correct, I will plug the solutions back in to the original equation.

a+c=30

10+20=30

30=30, True

12a+8c=280

12*10+8*20=280

120+160=280

280=280, True

Therefore, a=10 and c=20.

Answer:

[tex]x^2+2x+4[/tex]

Step-by-step explanation:

This expression can also be written as a difference of cubes:

[tex]x^3-2^3[/tex]

A important formula to remember is:

[tex]a^3-b^3=(a-b)(a^2+ab+b^2)[/tex]

We can use this to factor this expression:

[tex]x^3-2^3=(x-2)(x^2+2x+4)[/tex]

Therefore the other factor is:

[tex]x^2+2x+4[/tex]

Answer:

Zachary invests $470 into the account that earns 5% simple interest. At the end of 2 years, the account balance is $517

Step-by-step explanation:

I took the test

The new account balance at the end of 2 years is $517.

5 years

Using this formula

I= (P+r×t)

Where:

I=Interest=?

P=Principal=$400

r=Interest rate=3.5%

t=Time=5 years

Hence:

I= ($400×0.035 x 5)

I= $70

2 years

I=Interest=?

P=Principal=$470

r=Interest rate=5%

t=Time=2 years

I=($470+0.05×2)

I=$47

New balance:

New balance=$400+$70+$47

New balance=$517

Inconclusion the new account balance at the end of 2 years is $517.
