Answer:
A. 35°
Step-by-step explanation:
Step 1: Derive an Equation
To answer this question, we will use what's called the Triangle Sum Theorem, which states that the sum of all of the interior angles of a triangle is 180°.
By this theorem, in ΔSRT (the triangle, not the angle), the sum of m∠TSR, m∠RTS, and m∠SRT is 180°. Putting this into a mathematical equation gives us the following:
m∠TSR + m∠RTS + m∠SRT = 180°
Now, from the picture, we can see that m∠TSR = 20° and m∠RTS = 125°. Substituting these values into our original equation gives us:
20° + 125° + m∠SRT = 180°
Step 2: Solve the Equation
Solving for m∠SRT, we get:
20° + 125° + m∠SRT = 180°
145° + m∠SRT = 180° (Simplify the LHS by combining like terms)
m∠SRT = 35° (Subtract 45° from both sides of the equation to isolate m∠SRT)

[tex]Hi!~I~am~beinggreat78,~and~I~will~help~you![/tex]
Let's start by breaking down the problem.
This is how it should look. ↓
[tex]60[/tex] ÷ [tex]20[/tex] ⇒ [tex]+ 3[/tex] ⇒ [tex]x * 5^2[/tex]
What does that x mean? x is just a substituted value for the first 2 equations.
Now, we can solve.
[tex]60[/tex] ÷ [tex]20[/tex] [tex]= 3[/tex]
Add 3
[tex]3 + 3 = 6[/tex]
Now, multiply 6 times 5 squared. What does 5 squared mean? 5 squared is just 5 times itself once. You most likely want to solve 5 squared before multiplying.
[tex]5^2~or~5 * 5 = 25[/tex]
And now for the last step, multiply 25 times 6
[tex]25 * 6 = 150[/tex]
With that information, the problem is solved! Your answer is 150
This is a simple PEMDAS equation.
We will start with 5^2 because there are no parentheses and the second step is exponents. 5^2 is 25.
Now our equation looks like this: 60/20+3x25.
The next step will be multiplication. 3x 25 is 75.
Our equation now look like this: 60/20+75.
The next step is dividing. 60/20 is 3.
The equation now looks like this: 3+75 which is 78.
And that’s your answer.

Answer:

Step-by-step explanation:
Rewrite "(x - 4)/4" in a different way:
⇒ 8 + x/2 = (x - 4)/4 - 1
⇒ 8 + x/2 = x/4 - 4/4 - 1
Simplify the R.H.S:
⇒ 8 + x/2 = x/4 - 1 - 1
⇒ 8 + x/2 = x/4 - 2
Add 2 both sides and subtract x/2 both sides:
⇒ 8 + x/2 = x/4 - 2
⇒ 8 + 2 = x/4 - x/2
⇒ 10 = x/4 - 2x/4
Simplify the R.H.S:
⇒ 10 = x/4 - 2x/4
⇒ 10 = -x/4
Use cross multiplication:
⇒ 10 × 4 = -x
⇒ -(40) = x = -40

Answer:
15
Step-by-step explanation:
We have been told:
Alex made 18 free throws Quinn made 1/6 less than thatTherefore, to find the number of throws Quinn made, we need to find 1/6 of 18, then subtract this from 18 (the number of throws Alex made).
[tex]\begin{aligned}\sf \dfrac16\:of\:18 &=\sf \dfrac16 \times 18\\\\ & = \sf \dfrac{1 \times 18}{6}\\\\ & = \sf\dfrac{18}{6}\\\\ & =\sf18 \div 6\\\\ & =\sf3\end{aligned}[/tex]
Now we have calculated 1/6 of 18, we can subtract it from 18 to find the number of throws Quinn made:
⇒ Number of throws Quinn made = 18 - 3 = 15

Solve f(x)=2, if f(x)=1/2x-3
Both equations are set to equal f(x) so the solution would be the two equations set to equal each other
2 = 1/2x - 3
==> add 3 to both sides
5 = 1/2x
==> multiply both sides by 2
10 = x

Part A: the second choice
Part B: 72 blocks
Step-by-step explanation:
The prism has 3 layers and 24 blocks per layer. The base of each layer of the second choice has a width of 8 and length of 3.
8*3=24.
Multiply the 24 blocks on each layer with the 3 layers and we get 72 blocks in total.
We can check this by multiplying the dimensions of the prism together. 3*3*8=72 and this verifies that we are correct.
Part A is the second choice & part B is 72

[tex]\sf\rightarrow 53712.4[/tex]
Answer:
53712.4
Step-by-step explanation:
To represent this expression as a number, we need to simplify the expression to obtain a specific number (solution). The first step would be to simplify the exponent in the expression.
Simplifying the exponent:
⇒ 53.7124 x 10^{3}
⇒ 53.7124 x 10 x 10 x 10
Note: Each 10 will shift the decimal 1 place to the right.
⇒ 537.124 x 10 x 10
⇒ 5371.24 x 10
⇒ 53712.4

∠1 = 63 - 2x°∠2 = 72 - 3x°And if we look at the diagram, we can see that angles 1 and 2 are corresponding, and corresponding angles are congruent(meaning they measure the same degrees).
So all we need to do now, is set up the equation to angle 1 being equal to angle 2.
(63 - 2x) ← [angle 1] = (72 - 3x) ← [angle 2]
Solve;
63 - 2x = 72 - 3x

63 = 72 - 1x

4 + 4.75a = 3 + 5.55a
Answers
4 - 3 = (5.55 - 4.75)a
1 = 0.8a
a = $1.25 [A.]
Rearrange the term’s 4.75a-5.55a =3-4
Combine like terms-8a=3-4
Divide both side of the equation by the coefficients of variables a=-1/-0.8
