Answer 1

Answer: x is equal to 4

Step-by-step explanation:

A triangle's angles sums up to 180°. So we already know that the three angles in this triangle add up to 180°. The equation would be as following.

(18x - 12) + 15x + (10x + 20) = 180

We first add like terms together.

43x + 8 = 180

We then substract 8 on both sides.

43x = 172

We finally divide 43 on both sides.

x = 4

The sum of two numbers is -12.6 identify the two negative addends that make the statement true

Answers

The sum of the two numbers = -12.6

The two negative addends that make the statement "The sum of two numbers is -12.6" true are -8.6 and -4

Let x represent the first negative number

Let y represent the second negative number

x   +  y   =   -12.6

To make the above equation to be true, assume a value f x that is negative but greater than -12.6

Let x = -8.6

Substitute x = -8.6 into the equation x + y = -12.6

-8.6  +  y   =  -12.6

Add 8.6 to both sides of the equation

-8.6  +  8.6  +  y   =  -12.6  +  8.6

y   =  -4

As a proof:

-8.6  -  4   =   -12.6

The two negative addends that make the statement "The sum of two numbers is -12.6" true are -8.6 and -4

Find the measure of each marked angle.

Answers

Answer:

X= 15, m∠78°

Step-by-step explanation:

Since the angles are vertically opposite

Therefore their measurements are equal

Therefore (2x + 48 ) = (5x + 3 )

So,

[tex](2x + 48) = (5x + 3)\\(2x-5x)= (3-48)\\-3x = -45\\x = -45/-3\\x = 15[/tex]

[tex](2x + 48)\\=( 2* 15 + 48)\\= 30 + 48\\=78\\\\(5x + 3)\\=(5*15 + 3)\\=75+3\\=78[/tex]

They both equal 78°

Step-by-step explanation:

We can substitute in y here as 30, so that 60+102=2x^2

91=x^2

So x will be the square root of 91

If f(x) is an exponential function where f(-2) = 1 and f(7) = 63, then find the
value of f(1), to the nearest hundredth.

Answers

An exponential function is represented as: [tex]\mathbf{f(x) = ab^x}[/tex]

The value of f(1) is 3.95

f(-2) = 1 means that:

[tex]\mathbf{ab^{-2} = 1}[/tex]

f(7) = 63 means that:

[tex]\mathbf{ab^{7} = 63}[/tex]

Divide both equations

[tex]\mathbf{\frac{ab^7}{ab^{-2}} = \frac{63}{1}}[/tex]

Apply law of indices

[tex]\mathbf{b^9 = 63}[/tex]

Take 9th root of both sides

[tex]\mathbf{b =1.58}[/tex]

Make a, the subject in [tex]\mathbf{ab^{-2} = 1}[/tex]

[tex]\mathbf{a = \frac{1}{b^{-2}}}[/tex]

[tex]\mathbf{a = b^2}[/tex]

Substitute [tex]\mathbf{b =1.58}[/tex]

[tex]\mathbf{a = 1.58^2}[/tex]

[tex]\mathbf{a = 2.50}[/tex]

So, we have:

[tex]\mathbf{f(x) = ab^x}[/tex]

[tex]\mathbf{f(x) = 2.50 \times 1.58^x}[/tex]

Substitute 1 for x

[tex]\mathbf{f(1) = 2.50 \times 1.58^1}[/tex]

[tex]\mathbf{f(1) = 3.95}[/tex]

Hence, the value of f(1) is 3.95

The ratio of blue crayons to red crayons in a classroom is 32:28. The classroom has 16 blue crayons.

How many red crayons are in the classroom?

Answers

32/28=16/x
32x= 448

There are 14 red crayons in classroom

Answer:

14 red crayons

Step-by-step explanation:

since we already know the ratios of the crayons we are going to use ratio and proportion to solve our question B:R is 32:28 and they are directly proportional meaning we can scale the quantities by multiplying.32:28 and 16:R , r is the unknown quantity ,then we cross multiply  the 2 ratios to get 32R= 448, then we divide by32 both sides so we can remain with the value of R which is 14

1) Delectable Cookie Company sells chocolate chip cookies for $6.95 per pound and
white chocolate cookies for $5.95 per pound. How many pounds of chocolate chip
cookies should be mixed with 4 pounds of white chocolate cookies to obtain a mixture
that sells for $6.75 per pound?

Answers

Answer: 16lbs

Step-by-step explanation: CCC=Chocolate Chip Cookie; WCC=White Chocolate Cookie.

Set up a table showing the pricing ($/lb) and pounds (lbs) for both cookies. The total value of the WCC is $23.8 ($5.95/lb x 4 lbs). The value of the CCC is 6.95x, where x is the lbs CCC.

CCC WCC

6.95 5.95 $/lb

x 4 lbs

6.95x 23.8 $ Total value [$/lb * lbs]

We want x lbs of CCC cookies such that the total value of cookies divided by the total number of lbs is equal to $6.75/lb. That can be written as:

(6.95x + 5.95*4)/(x+4) = 6.75 [Total value of cookies divided by total weight equals $6.75]

(6.95x + 23.8)/(x+4) = 6.75

6.95x + 23.8 =6.75x + 27

0.2x = 3.2

x = 16 lbs

We need 16 lbs of CCC added to the 4 lbs of WCC for a total weight of 20 lbs and a price of $6.75/lb.
