Answer:

Step-by-step explanation:

Let's solve for x.

1.5x+0.5y=12

Step 1: Add -0.5y to both sides.

1.5x+0.5y+−0.5y=12+−0.5y

1.5x=−0.5y+12

Step 2: Divide both sides by 1.5.

1.5x

1.5

=

−0.5y+12

1.5

Answer:

8 and one thirds

Step-by-step explanation:

5 times 5 is equal to 25 and 25 divided by 3 is 8.3333

Answer:

$8.33

Step-by-step explanation:

So, to figure out how much one mango costs, I did $5 divided by 3, which gave me 1.66.

I then multiplied that by 5 to see how much 5 mangos cost, and I got $8.33

Answer:

30

Step-by-step explanation:

since x=5, and it's 6x, it'd be the same as 5x6, or 6(5).

Answer:

I think it should equal 30

Step-by-step explanation:

If x is 5 it would be 6(5) so you multiply 6 and 5 which equals 30

Answer:

Step-by-step explanation:

-7x + 12 + (-8x + 48) = 180

-15x + 60 = 180

-15x = 120

x = -8

m<BDC= -7(-8)+ 12 = 56 + 12 = 68

m<CBA = -8(-8)+48 = 64+48 = 112

Answer:

x=-8

mbdc=68

Step-by-step explanation:

bda is a straight angle

=> bdc+cda=180°

=> (-7x+12)°+(-8x+48)°=180°

=> -15x+60=180°

=> -15x=120°

=> x=-8

bdc= (-7)×(-8)+12=68°

Answer:

5.5 hours (If rounded, then 6)

Step-by-step explanation:

If you divide 100 by 2, it would be 50. So then you would have to divide 275 by 50, which will get you your time. Which is 5.5 hours.

Step-by-step explanation:

Answer: Balls 4 and 9 are furthest apart

Step-by-step explanation:

The 9 and 4 ball are farthest from each other.

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given that, three billiard balls are left on the table, we need to determine which two balls are furthest apart.

So, the balls are in the shape of a triangle, we know that, the greatest angle is opposite of the largest side,

So, we will find the angles first,

Since the angles of a triangle add up to 180 degrees,

(x-5)+(2x+1)+(3x-8)=180,

6x-12=180.

x = 32.

That means the 9 ball is at 27 degrees, the 4 ball is at 65 degrees, and the 5 ball is at 88 degrees.

Based on the angles, the farthest distance would be between balls 9 and 4.

Hence, the 9 and 4 ball are farthest from each other.

40 - 26 = 14

14 / 2 = 7

Answer:

The solutions are:

-28.25, -14.5, -2.25

Step-by-step explanation:

Given compound inequality is:

[tex]-17.5\leq \frac{2x+4}{3} <17.5[/tex]

The compound inequalities are broken down into two inequalities to find the solution

The two inequalities will be:

[tex]\frac{2x+4}{3} \geq -17.5[/tex]   AND   [tex]\frac{2x+4}{3}<{17.5}[/tex]

Solving both inequalities one by one

[tex]\frac{2x+4}{3} \geq -17.5\\2x+4 \geq -52.5\\2x \geq -52.5-4\\2x \geq -56.5\\\frac{2x}{2} \geq \frac{-56.5}{2}\\x \geq -28.25\\\frac{2x+4}{3} < 17.5\\2x+4 < 52.5\\2x < 52.5-4\\2x \geq 48.5\\\frac{2x}{2} \geq \frac{48.5}{2}\\x < 24.25[/tex]

The solution is:

-28.25 ≤ x < 24.25

We have to see which options lie in the solution range.

The solutions are:

-28.25, -14.5, -2.25

Answer:

Pineapple juice = 2 cups

Step-by-step explanation:

Francine uses 2/3 cup of pineapple juice for every 1/3 cup of orange juice to make a smoothie , how many cups of pineapple juice does Francine use for 1 cup of orange juice

Pineapple juice : Orange juice

2/3 cup : 1/3 cup

how many cups of pineapple juice does Francine use for 1 cup of orange juice

Let x = cups of pineapple juice

Pineapple juice : Orange juice

x cup : 1 cup

Equate the ratios

2/3 cup : 1/3 cup = x cup : 1 cup

2/3 ÷ 1/3 = x / 1

2/3 × 3/1 = x / 1

6/3 = x / 1

Cross product

6 * 1 = 3 * x

6 = 3x

x = 6/3

x = 2

Pineapple juice = 2 cups

(x - 7)

Step-by-step explanation:

To factor the polynomial in form [tex]x^{2} +bx+c[/tex] find two factors of C that have a sum of B

B = -1

C = -42

Factors of 42:

1, 2, 3, 6, 7, 14, 21, 42

6 and -7 multiply to -42 and add to -1

Write in factored form:

(x + 6)(x - 7)

Answer:

(x - 7)(x + 6)

Step-by-step explanation:

Given

x² - x - 42

Consider the factors of the constant term (- 42) which sum to give the coefficient of the x- term (- 1)

The factors are - 7 and + 6 , since

- 7 × 6 = - 42 and - 7 + 6 = - 1 , thus

x² - x - 42 = (x - 7)(x + 6)

Answer:

NO

Step-by-step explanation:

Exponents are expressed as numbers or variables in superscript above a base number. When the exponent is equal to or greater than 2, it directs how many times the base number is to be multiplied. The numbers 1 and 0 are special exponents, and negative integers as exponents stand for reciprocal values.

Answer:

It matters of what the whole number in front is.

Step-by-step explanation:

For example: 6 to the power of 2 = 36  

if the first number is a decimal: 1.6 to the power of 2.56

Its NOT an exponent if the starting number is a decimal usually.

Answer:

B) The system graphs as one line.

Step-by-step explanation:

The solutions of systems are basically the points where the two lines of the linear equations meet, or intersect.

So, picture it like this: if a system of linear equations has INFINITE (never-ending) solutions, then it must mean that the two lines intersect at EVERY single one of their points. And if they intersect at every one of their points, then that must mean that they are the same line, even if the equations are written differently.

Answer:

Number of adult tickets = 180

Number of child tickets = 165

Step-by-step explanation:

Given:

Total number of ticket = 345

Total amount = $1,395

Cost of adult ticket = $5

Cost of child ticket = $3

Find:

Number of child and adult tickets

Computation:

Assume;

Number of child tickets = a

Number of adult tickets = b

So,

a + b = 345...........eq 1

3a + 5b = 1,395...........eq2

3 x in eq 1

3a + 3b = 1,035.........eq3

eq2 - eq3

2b = 360

b = 180

Number of adult tickets = 180

a + b = 345

a = 165

Number of child tickets = 165

Hi there!

[tex]\large\boxed{\text{x = 12, x = 5}}[/tex]

Problem 1:

The angles pictured are vertical angles, so each will be equivalent. Therefore:

(5x + 5)° = 65°

Subtract 5 from both sides:

5x = 60

Divide both sides by 5:

x = 12°.

Problem 2:

The two angles are supplementary, so they add up to 180°. Therefore:

180° = (9x)° + (12x + 75)°

180 = 9x + 12x + 75

Combine like terms:

180 = 21x + 75

Subtract 75 from both sides:

105 = 21x

Divide both sides by 21:

x = 5°.

question one

180 - 6 = 174 ( c )

because angles on a straight line are 180 !

question two

AB = 6 units

AC = 8 units

( i just counted the boxes )

BC = square root ( 36 + 64 ) = 10
