Solve the real-world situation by using the substitution method. The number of DVDs sold at a store in a month was 935 and the number of DVDs sold decreased by 12 per month. The number of Blu-ray discs sold in the same store in the same month was 517 and the number of Blu-ray discs sold increased by 26 per month. Let d represent the number of discs sold and t represent the time in months. The system of equations lbrace d = 935 − 12t d = 517 + 26t can be used to represent this situation. If this trend continues, how many months will the number of DVDs sold equal the number of Blu-ray discs sold? How many of each is sold in that month? There will be ______ DVDs and Blu-Ray discs sold per month in ______ months.
Answer:
t = 11 months
d = 803
Step-by-step explanation:
d = 935 − 12t
d = 517 + 26t
how many months will the number of DVDs sold equal the number of Blu-ray discs sold
Equate both equations to solve for the number of months
935 − 12t = 517 + 26t
935 - 517 = 26t + 12t
418 = 38t
t = 418 / 38
t = 11 months
How many of each is sold in that month?
d = 935 − 12t
= 935 - 12(11)
= 935 - 132
= 803
d = 517 + 26t
= 517 + 26(11)
= 517 + 286
d = 803
There will be 803 DVDs and Blu-Ray discs sold per month in 803 months.

A person standing 154 feet from the base of a church observed the angle of elevation to the church's steeple to be 25∘. How tall is the church?
Answer:
71.764 feet
Step-by-step explanation:
See attached the rough sketch for your reference
Step one;
Given data
The angle of elevation= 25°
From the triangular diagram, we can see that the height of the church is the opposite, while the distance of the person from the church is the adjacent
Step two:
Applying SOH CAH TOA
tan∅= opp/adj
tan 25= opp/154
0.466= opp/154
cross multiply
0.466*154= opp
opp= height of church = 71.764 feet

Please help me find an equation for this
Answer:
The equation that represents this situation is x + 3x + (x - 4) + 2(x - 4) = 72, where x is Erik's age
Step-by-step explanation:
Let us solve the question
Assume that Erik is x years old
∵ Erik is x years old
∵ Erik is [tex]\frac{1}{3}[/tex] as old as Dawn
→ That means x = [tex]\frac{1}{3}[/tex] Dawn
∴ x = [tex]\frac{1}{3}[/tex] Dawn
→ Multiply both sides by 3
∴ 3x = Dawn
∴ Dawn is 3x years old
∵ Jiro is 4 years younger than Erik
→ That means Jiro = x - 4
∴ Jiro is (x - 4) years old
∵ Alita is 2 times as old as Jiro
→ That means Alita = 2 × (x - 4)
∴ Alita = 2 × (x - 4)
∴ Alita is 2(x - 4) years old
∵ The sum of all their ages is 72
→ That means add their ages and equate the sum by 72
∴ Erike's age + Dawn's age + Jiro's age + Alita's age = 72
∴ x + 3x + (x - 4) + 2(x - 4) = 72
The equation that represents this situation is x + 3x + (x - 4) + 2(x - 4) = 72, where x is Erik's age
When do you need to flip the inequality sign when solving?
Answer:
When you divide by a negative.

What number does x stand for in this equation?
- 7x + 6= 27
A
21
B
2
C-3
D-7
Answer:
c. -3
Step-by-step explanation:
- 7x + 6= 27 [subtract 6 from both sides]
-7x = 21 [divide by -7 to isolate x]
x = -3
Answer:
The answer is C
Pay attention, here's why.
Step-by-step explanation:
Let's solve your equation.
−7x+6=27
Step 1: Subtract 6 from both sides.
−7x+6−6=27−6
−7x=21
Step 2: Divide both sides by -7.
−7x /−7 = 21/ −7

(NEED DONE QUICKLY) If the domain of a coordinate transformation that is reflected over the y-axis is (-6, 2), (4, 5), (2, -1), what is the range?
Answer:
Step-by-step explanation:
Remark 1
If you are using a mirror on the y axis, then only the x value is changed. The y value remains the same.
For (-6,2), -6 changes into plus 6
The new point is (6,2)
For (4,5), 4 changes to minus 4
The new point is (-4,5)
For (2,-1) the new point is (-2,-1)
Remark 2
But none of those are the answer you want. What you want is what happens to the y value? The answer is it remains the same. The y value is the range. So the answer goes from (-1 to 5) just as it did before.
