Step-by-step explanation:
Complementary angles sum to 90° , then
5x + 7 + 8x - 21 = 90 , that is
13x - 14 = 90 ( add 14 to both sides )
13x = 104 ( divide both sides by 13 )
x = 8
Then the measure of the angles are
5x + 7 = 5(8) + 7 = 40 + 7 = 47°
8x - 21 = 8(8) - 21 = 64 - 21 = 43°
--------------------------------------------------------
let the angle be x then its complement is (90 - x) and
x = 2(90 - x) + 21
x = 180 - 2x + 21
x = 201 - 2x ( add 2x to both sides )
3x = 201 ( divide both sides by 3 )
x = 67
The measure of the angle is 67°

How to calculate the distance between two runners?? Ex) A finish 100m in 10.93 sec, and B finish in 10.49 sec, by how many meters did B won?? (Pls help me)
Answer:
The average speed of A is
100m ÷ 10. 93s = 9.14m/s
The average speed of B is
100m ÷ 10. 49s = 9. 53m/s
The average speed that B is faster than A is 9. 53 - 9. 14 = 0. 42m/s
The speed that B is faster than A is
0. 42m/s × 10. 49s = 4. 40m
So, B won by 4. 40m

Solve for x

Step-by-step explanation:
There are several methods to solve equations of the type AX = XB. These type of equations occur in domains like robotics, for which solutions have been proposed like the Tsai and Lenz method [IEEE 1987], for example. 1) I feel solving the equation XA = XB is not the same as solving the known form AX = XB. Am I right? 2) Neither can it be solved like the Sylvester equation, because even that requires AX+XB=CAX+XB=C form. What i have is XA=XBXA=XB, a redundant set of equations. That is,
A1.XA2.XAn.X=X.B1=X.B2⋮=X.BnA1.X=X.B1A2.X=X.B2⋮An.X=X.Bn
If i am correct, these could be rewritten into another form like AX=BXAX=BX. Should i rewrite the equation and try to solve this problem using any other existing methods?

Find the midpoint of me of the line segment
help needed urgently pls
Answer:
The sum of the larger and smaller number is 15.
Step-by-step explanation:
Let x = smaller number
Let y = larger number
Set up a system of equations.
2y - x = 21
2y + x = 27
Add the two equations together to cancel out x
4y = 48
Divide both sides by 4
y = 12
Plug value into either equation to find x
2(12) - x = 21
24 - x = 21
x = 3
12 + 3 = 15
Is my answer correct?
Answer:
yes $56 is correct
Step-by-step explanation:
The 3 part of the ratio relates to $42 , then
$42 ÷ 3 = $14 ← value of 1 part of the ratio , then
4 parts = 4 × $14 = $56
John had $200 in his bank account. He made a purchase at the grocery store that was $1.50 more than he had in his account. Select the point o
the number line that represents the balance of his bank account after buying groceries.
Answer: on the number line put -1.50 (1 and a half (1 1/2))
Step-by-step explanation:
$1.50 more than his account is $200.
the balance should be $-1.50
on the number line put -1.50

At a school camp there is enough food for 150 students for 5 days.
a How long would the food last if there were only 100
students?
Answer: 7.5 days or 7 days (round down)
Step-by-step explanation:
STEP ONE: Find the total number of food in 5 days
150 students
5 days
150 × 5 = 750 unit of foods
In another word, there is enough food for 750 students in one day.
STEP TWO: Find the days this amount of food would last for 100 students
750 unit of food
100 students
750 ÷ 100 = 7.5 days
7.5 (round down) = 7 days
**Disclaimer** Rounding down to 7 days means that these food are enough for all 100 students for a whole day. If keeping 7.5 days, this would mean either the students would not be full, or there would only be half of the student body could get food. From my knowledge, I would round down. HOWEVER, this all depends on the rules that you would apply in mathematics.
Hope this helps!! :)

Shelly and Terrence earned points in a game by come playing various tasks. Shelly completed x tasks and scored 90 points on each one. The expression below shows Terrence’s total points in the game:
90x - 20
What does the constant term of expression represent?
Answer:
The correct answer to the question is:
The difference between Shelly's and Terrence's total points.
Answer:
B
Step-by-step explanation:
The answer or the only choice you could pick, is D.
But it is not correct - not really.
The question says that 90x - 20 represents Terrence's points. Only if D is correct does 20 show his tasks. The question must have 2 answers.
So which one do you pick? You should never have to deal with this kind of question. The answer I think you need to give is B, but I wouldn't bet the farm on it.
The question should say 90*x - 20 has Terrence's tasks in it. Then the answer is B.

Answer:
y^-24, x^-2 y^-5, 1/ y^24, x^2/y^11, x^2y^-11 and 1/ x^2y^5
ok i tried searching up the problem and how to solve it but didn`t come up with much.
i don`t know if this changes anything, but I noticed that some of these answers are opposites
ex (from the sequence you gave me in the comments below) : y^-24, x^-2, y^-5, y^24, x^2, y^5
maybe thats what it meant by matching the expressions?

At a day care center for toddles there is one
teacher for every 7 toddlers. Determine
whether there is a direct variation between
the number of toddlers, y, and the number of
teachers, x. If so, find the equation of direct
variation.
Answer: x = 7y.
Step-by-step explanation: There is direct variation between the number of toddlers and the number of teachers. We know this because when one increases, the other would as well. We can write the equation of direct variation as x = 7y.

y=x^2-2x-5 vertex form
Hey there! I'm happy to help!
First, we'll want to find the vertex of this parabola.
Given the equation y=ax^2+bx+c, the formula for the x-coordinate of the vertex is always [tex]-\frac{b}{2a}[/tex].
In our equation here, our a is 1 and our b is -2.
[tex]-\frac{-2}{2}=\frac{2}{2}=1[/tex]
Now that we have our x-value of our vertex, we can plug it into our equation to find our y-coordinate.
y=1²-2(1)-5
y=1-2+5
y=-1+5
y=4
So, our vertex is at (1,4).
Vertex form is y=a(x-h)²+ k where (h,k) is our vertex. We know now that our vertex is (1,4) and we also know that our a is 1, so we can simply plug it in to this equation.
y=(x-1)²+4
