Answer:

a triangle always equals 180 degrees so

63+ 2x+8 + x+7 =180

solve for x

and then plug it back into original equation

let me know if this makes sense

13. jewelry marena is using a certain number of blue beads in a bracelet
kherson [118]

The simplest expression that represents the total number of beads in her bracelet design is 2b + 7.

Expression:

An expression is the  sentence with a minimum of two numbers or variables and at least one math operation.

This math operation can be addition, subtraction, multiplication, or division.

The structure of an expression is:

Expression = (Number/variable, Math Operator, Number/variable)

Given,

Jewelry Marena is using a certain number of blue beads in a bracelet

design. she will use 7 more red beads than blue beads.

Here we need to write an expression in simplest form that represents the total number of beads in her bracelet design.

Assign a variable for the unknown value.

Let b be the number of blue beads for the bracelet.

The number of red beads will be represented as b + 7.

Determine the expression for the total number of beads.

Then we can written it as,

=> b + (b +7)

=> 2b + 7.

Therefore, the total number of beads can be written as 2b + 7.

What is the degree measure of x in this triangle?
Crank
So this is trig, and when it comes to right (90°) triangles, it's imperative that you know:
SOH-CAH-TOA

Sine (x) = Opposite/Hypotenuse
Cosine (x) = Adjacent/Hypotenuse
Tangent (x) = Opposite/Adjacent

*hypotenuse is always the largest side, and the one opposite the 90° angle in right triangles

therefore we'll use SOH, because the opposite of x (O) and the hypotenuse (H) are given:

Sine (x) = Opposite/Hypotenuse
Sine (x) = 32/58 = 16/29 = 0.552
Sine (x) = 0.552
now we use something called arc-sine, or
{(sin)}^{ - 1}
it's basically a fancy function of most advanced calculators, so we'll plug it in as:
x =  {(sin)}^{ - 1} (0.552)
x = 33.49° --> answer B) is correct

Chase and sara went to the candy store. Chase bought 5 pieces of fudge and 3 pieces of gum for 5.70. Sara bought 2 pieces of fud
tamaranim1 [39]

Let, price of fudge and gum is x and y respectively.

Converting given statements into mathematical equation.

We get :

5x + 3y = 5.70  ....1)

2x + 10y = 3.60 ....2)

Solving equation 1 and 2, we get :

x = $1.05 .

y = $0.15 .

Price of buying 20 pieces of fudge and 20 pieces of bubble gum is :

P = 20( 1.05 ) + 20( 0.15 )

P = $24

Hence, this is the required solution.

To transform a mixed number to an improper fraction, we must multiply the denominator by the large number, and add the numerator.


So for 14\frac{2}{7}: (14*7)+2=100


But we also put this over the denominator in the mixed number, so we get: \frac{100}{7}.


Then we do the same for 5\frac{2}{3}:


(5*3)+2=\frac{17}{3}


Then we must find a common denominator. Let's use 21 (multiply 3 and 7):


\frac{100}{7} *\frac{3}{3}= \frac{300}{21}


\frac{17}{3}* \frac{7}{7} =\frac{119}{21}


Now that we have a common denominator, we can subtract across:


\frac{300}{21} -\frac{119}{21}= \frac{181}{21}


Since \frac{181}{21} cannot be reduced any further, we are going to leave this as our answer.


So the answer is \frac{181}{21}.
