The figure shows how one side street intersects the main road to form two angles.
Answers
Answer:
x=31
Step-by-step explanation:
Hey There!
Those angles are a pair of supplementary angles meaning that they will add up to equal
So to find what x equal we have to set up an equation and because those angles are supplementary we use the equation of 180=4x+x+25 because like before the sum of supplementary angles is equal to 180
Now that we have the equation it is time to solve for x
180=4x+x+25
Step 1 combine any like terms
Like terms are any similar variables or constants and in this case we have two like terms 4x and x so we should add them together
4x+x=5x
Now we have
180=5x+25
Step 2 our goal is to get the variable (x) on one side and the constant on the other. What we want to do is get rid of the 25 and to do that we subtract 25 but whatever we do to one side we have to do to the other
180-25=155
25-25 cancels out
now we have 155=5x
Our final step is to divide each side by 5
5/5 cancels out
155/5=31
We can conclude that x=31

∠WXY and ∠ZXY are adjacent angles. What equation must always be TRUE? m∠WXY=m∠ZXY
m∠WXY+m∠ZXY=90°
m∠WXY+m∠ZXY=180°
m∠WXY+m∠ZXY=m∠WXZ
Pls actually answer and fast
Answers
Answer:
m∠WXY+m∠ZXY=m∠WXZ
Step-by-step explanation:
You don't know the angles to be congruent (equal measures), complementary (measures add to 90 deg), or supplementary (measures add to 180 deg); all you know is that they are adjacent, so the sum of the measures of the two smaller angles equals the measure of the larger outer angle.
Answer: m∠WXY+m∠ZXY=m∠WXZ
The equation that should be true is m∠WXY+m∠ZXY=m∠WXZ
Angles:
The angles should be congruent when it is equal measures, It should be complementary when it measures add to 90 deg, or supplementary when it measures add to 180 degree. Moreover, the sum of the measures of the two smaller angles should be equivalent to the measure of the larger outer angle.

Can someone explain how the quadratic equation works with an example!
Answers
Answer:The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) .The four methods of solving a quadratic equation are factoring, using the square roots, completing the square and the quadratic formula.

Rodrigo and Melissa went to the art supply store to buy drawing materials. Rodrigo bought 10
pencils and 7 felt-tip markers for a total of $19.00. Melissa bought 3 pencils and 5 felt-tip markers
for a total of $10.05. Which of the following systems of equations could be used to determine
the cost of one pencil, P, and one felt-tip marker, m?
Answers
Answer:
10P + 7m = 19 .......... 1
3P + 5m = 10.05 .......... 2
Step-by-step explanation:
Let the cost of pencil be represented by P, and felt-tip by m. So that;
Rodrigo bought 10 pencils and 7 felt-tip at the cost of $19.0.
⇒ 10P + 7m = 19 .......... 1
Melissa bought 3 pencils and 5 felt-tip at the cost of $10.05.
⇒ 3P + 5m = 10.05 .......... 2
From equations 1 and 2,
10P + 7m = 19 .......... 1
3P + 5m = 10.05 .......... 2
Multiply equation 1 by 3, and 2 by 10 to have;
30P + 21m = 57 ......... 3
30P + 50m = 100.5 ....... 4
Subtract equation 3 from 4,
30P - 30P + 50m - 21m = 100.5 - 57
29m =43.5
m = [tex]\frac{43.5}{29}[/tex]
= 1.5
m = 1.5
Substitute the value of m in equation 2,
3P + 5m = 10.05 .......... 2
3P + 5(1.5) = 10.05
3P = 7.5 = 10.05
3P = 3
P = 1.0
Thus, the cost of a pencil is $1.0 and that of a felt-tip is $1.5.

Amelia runs a catering business. Based on her records, her weekly profit can be modeled by P=-2x^2+152x-150P=−2x 2 +152x−150, where xx is the number of meals she caters and PP is her profit.
Answers
Answer:
The least number of meals Amelia needs to cater in order to begin making profit = 38 meals.
Step-by-step explanation:
Given - Amelia runs a catering business. Based on her records, her weekly
profit can be modeled by P= -2x² + 152x - 150, where x is the
number of meals she caters and P is her profit. When P is negative,
Amelia losses money.
To find - What is the least number of meals Amelia needs to cater in order
to begin making profit.
Proof -
As given, P = -2x² + 152x - 150
Now,
Above the break-even point, she only get profit
The break -even point is a point where there is no profit, and no loss.
Now,
For break-even point,
[tex]\frac{dP}{dx} = 0[/tex]
⇒[tex]\frac{d}{dx}( -2x^{2} + 152x - 150) = 0[/tex]
⇒-4x + 152 = 0
⇒- 4x = - 152
⇒4x = 152
⇒x = [tex]\frac{152}{4}[/tex] = 38
∴ we get
If Amelia caters at least 38 meals , then she makes Profit.

Marty, Doc, and Einstein are all traveling very fast in
their cars. Marty and Doc's position over time are
shown below in the tables. Einstein only collected two
data points during his trip; after 3 hours he travelled
240 miles and after 4 hours he travelled 320 miles.
Who drove the fastest? Show work. Explain on the
lines below.
Answers
Answer:
Doc drove the fastest.
Step-by-step explanation:
The first thing you want to do is figure out how many milese they are traveling per hour. We know that Einstein has these two time stamps (hour/miles) ; 3/240 and 4/320.
so divide the hour by the number of miles:
3÷240=80
just to make sure I did the four hour one as well;
4÷320=80
Do the same thing for doc and marty!
Doc4÷340=85
Marty4÷100=0.04
The answer that you get from the division problems is the number of miles that they travel each hour.

The mass of Parcel A was 0.7 kg. Parcel B was heavier than Parcel A.
Parcel C had the same mass as Parcel B. The total mass of the three
parcels was 2.5 kg. What was the mass of Parcel C?
Answers
Answer: 0.9kg
Step-by-step explanation:
Since we are informed that Parcel C had the same mass as Parcel B, let their mass be represented by x.
Therefore,
Parcel A + Parcel B + Parcel C = 2.5
0.7 + x + x = 2.5
0.7 + 2x = 2.5
2x = 2.5 - 0.7
2x = 1.8
x = 1.8/2
x = 0.9
The mass of parcel C is 0.9kg
