Step-by-step explanation:
x + y = 72
x - y = 40
x = y + 40
so, the first equation is then
y + 40 + y = 72
2y + 40 = 72
2y = 32
y = 16
x = y + 40 = 16 + 40 = 56

If B=-2t+1B=−2t+1 and A=t+9,A=t+9, find an expression that equals 2B+2A2B+2A in standard form.
The value of 2B+ 2A -2t + 20.
what is Algebra?Algebra is the part of mathematics that helps represent problems or situations in the form of mathematical expressions.
Given:
B=-2t+1
A=t+9
we have to find the expression that is equivalent to 2A + 2B
so,
2A + 2B
=2( t + 9) + 2( -2t + 1)
=2t + 18 - 4t +2
=2t - 4t + 18 +2
=-2t + 20
Hence, the value of 2A + 2B = -2t + 20

When applying PEMDAS, always work from left to right. True or False?
Answer:
False
Step-by-step explanation:
Sometimes, multiplication can occur after addition. For example, in 3+4*7, you don't add 3 and 4 first. You multiply 4 and 7 first since that's following the PEMDAS rule. After multiplying 4 and 7, then you add 3 to get a total of 31. ==> 3+4*7=3+28=31.

A two-column table with five rows. The first column, x, has the entries, negative 12, negative 11, negative 10, and negative 9. The second column, y, has the entries, 7, 11, 14, and 17.
Answer:
(A) is correct.
Step-by-step explanation:
As we know,
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
From the first graph:
The line goes through the points:
(-2, 2) and (2, 1)
y - 1 = (1-2)/(2+2)[x -2]
y - 1 = (-1/4)[x -2]
y = -x/4 + 1/2 + 1
y = -x/4 + 3/2
The constant additive rate of change = -1/4
Thus, the function shown in graph (A) has a constant additive rate of change is -1/4 option (A) is correct.

Step-by-step explanation:
e = 129° ( being vertically opposite angle )
Now ,
f + 129° = 180° ( being the angle in linear pair )
Again ,
d + 90° = 180° ( being the angle in linear pair )
d = 180° - 90°
d = 90°
☘️☘️☘️ ...
Answer:
d = 90° , e = 129° , f = 51°
Step-by-step explanation:
d and 90° are a linear pair and sum to 180° , that is
d + 90° = 180° ( subtract 90° from both sides )
d = 90°
e and 129° are vertically opposite angles and are congruent , then
e = 129°
f and 129° are a linear pair and sum to 180° , that is
f + 129° = 180° ( subtract 129° from both sides )
f = 51°
Fatima is selling cookies in a bake sale. She packages 20 cookies in 4 minutes. Describe the relationship between the amount of cookies and the time it takes to package them.
Based on the number of cookies that Fatima was able to package in a certain amount of time, the relationship between the cookies and the time it takes to package them is a single cookie is packaged in 12 seconds.
How long does it take to package the cookies?To find the amount of time it takes to package the cookies, the formula is:
= Number of minutes / Number of cookies
= 4 / 20
= 1/5
= 0.20 minutes
When converted to minutes, this is:
= 0.20 x 60 seconds per minute
= 12 seconds

A man drove 14 mi directly east from his home, made a left turn at an intersection, and then traveled 9 mi north to his place of work. if a road was made directly from his home to his place of work, what would its distance be to the nearest tenth of a mile?
If a road was made directly from his home to his place of work, its distance will be 16.6 mi.
If a man drives east from his home, makes a left turn at an intersection, and then travels north to his place of work, then the path he travels resembles the sides of a right triangle (see attached photo).
if a road was made directly from his home to his place of work, then this path will be the hypotenuse of the triangular path.
Using Pythagorean theorem, we can solve for the distance of the road.
c^2 = a^2 + b^2
where c is the distance of the road
a is the distance he travels to the east
b is the distance he travels up north
c^2 = a^2 + b^2
c^2 = (14 mi)^2 + (9 mi)^2
c^2 = (196 + 81) mi^2
c^2 = 277 mi^2
c = 16.64331698 mi
distance of the road = c = 16.64331698 mi

ZA and ZB are vertical angles. If mA = (5x +24)° and m/B= (6x - 5)°,
then find the measure of ZB.
The measure of ∠B = 189°
Here it is given that
∠A = (5x + 24)° and ∠B = (6x - 5)°
∠A and ∠B are vertical angles
Since vertical angles are always equal so
∠A = ∠B
5x + 24 = 6x - 5
add +5 on both sides, we get
5x + 24 + 5 = 6x - 5 + 5
5x + 29 = 6x
add -5x on both side, we get
5x - 5x + 29 = 6x - 5x
x = 29
Now put the value of x in 6x - 5
6 × 29 - 5 = 189
The measure of ∠B = 189°

Fill in the blanks to create an equation to represent the situation.
blank x + 2x + blank = 65
Based on the solution below, the number of people Deb can invite in order to spend a total of $65 is 5 people.
How do we use an equation to find a number?Given:
blank x + 2x + blank = 65 ............................... (1)
Where:
x = Number of people Deb can invite
First blank with x variable = 5; since Deb must pay an additional $5 for each person in the group
Second blank without x variable = 30; since Deb $30 to reserve a private karaoke room
Substituting the relevant values into equation (1) and solving for x, we have:
