You have $75 and need to buy 9 books at the bookstore and each book costs d dollars.
Write an algebraic expression to represent the amount of money left over.
Answer:
75-9d
Step-by-step explanation:
Hello,
The Answer to the question is 75-9d let me explain why,
you are asking, how much money is leftover. For me to get that I need to know that for every book it cost "d" dollars.
You know you have $75, and you need 9 books, we don't know how much they cost but we don't really need to.
75 - 9d
75 is the total. You need to subtract it by how many books your buying, 9.
The books are d amount of dollars, so we put 9d so that we know that for every 1 book it cost d amount so technically 9 is the amount of books times d, how much 1 book costs
Hope you can understand, I was having some trouble finding a way to explain it so my bad.
Also, I haven't done that in a while so sorry if I'm wrong

Figure D'EFG' is a dilation with center (0,0) of figure DEFG. What is the scale factor? Enter your answer in the box.
ILL GIVE BRAINLIST BUT PPLEASE HELP
Step-by-step explanation:
To work out the scale factor, divide one of the sides from the larger shape from the smaller shape so:
15/6 = 2.5
So your scale factor would be 2.5
And to check this, multiply 2.5 by 6 and u should get 15, so you know it is correct! :)

Matrix A has 2 rows and 3 columns whereas matrix B has3 rows and 2 column
Can AB be multiplied? Can BA be multiplied? Give the reason
Step-by-step explanation:
for any matrix multiplication number of columns of first matrix should be equal to number of rows of second matrix.
For AB
A has 3 columns and B has 3 rows so it matches . Hence can be multiplied.
For BA
B has 2 columns and A has 2 rows it also matches so can be multiplied

How do you find the height of a parallelogram without the area of it?
Answer:
See: https://brainly.in/question/12682555
Step-by-step explanation:
The link provided will take you to a differently worded explanation from another user.
You may see the "slant" referred to as a "hypoteneuse", as the shape created by the line of height(or altitude) is a right triangle. Given the base of the triangle and the "slant" or "hypoteneuse", format the equation (a²+b²=c²)-where a represents the height(altitude), b represents the base, and c represents the slant(hypoteneuse)- to fit your needs:
c²-b²=a². From this point, find the square root(√) of a. If it cannot be simplified further, then (√a) is your solution.
Lanu draws a rectangle that is 10 inches wide and 20 inches
long. Which rectangle described below has the same area?
F 5 inches wide and 25 inches long
G 8 inches wide and 25 inches long
H 15 inches wide and 15 inches long
J 15 inches wide and 25 inches long
Answer:
G
Step-by-step explanation:
A 10 x 20 inch rectangle has an area of 200 square inches. Therefore, we must find the rectangle that is also 200 square inches.
The formula of finding the area of a rectangle is multiplying width times length.
F) 5 * 25 = 125
G) 8 * 25 = 200
H) 15 * 15 = 225
J) 15 * 25 = 375
Therefore, rectangle G has the same area, since it is also 200 square inches.
Given that the random variable X = number of days a student sleeps in during the week, what is the correct notation for the probability that a student will sleep in at least 3 days?
Answer:
X > 3/7Step-by-step explanation:
X > 3/7
We know that the student sleeps in at least 3 days, but we don't know what the exact number is, we use an inequality where X is greater than or equal to 3 out of the 7 days.

Answer:
32
63
Step-by-step explanation:
m<BCA=180-148-32 Subtract 180-148 b/c x<BCA is along the straight line ACD. A straight line will have an angle of 180 degrees.
m<CAB=180-32-85=63 All triangles have angles which add up to 180 degrees. Subtract 32 and 85 from 180 to get 63.
Step-by-step explanation:
148 + x = 180
x = 180 - 148
x = 32
Find m<CAB basically means find the measure of the angle of A ( m<A )
m<B + m<A + x = 180
85 + m<A + 32 = 180
117 + m<A = 180
m<A = 180 - 117
m< A = 63, so m<CAB = 63
And m<BCA means find the measure of angle C(m<C) or as we did it earlier as x, which is the same thing.
So m<BCA = 32

2. Classify the angle as acute, obtuse, right or straight.
O acute
O obtuse
Oright
straight
HELP ASAP
Answer:
Please include the details of the angle
Step-by-step explanation:
When the angle is 93 degrees, the the angle is a obtuse angle. option B is correct.
Given that the measure of angle A is 93 degrees, we can classify the angle as follows:
Angle A = 93 degrees
We know that if angle is less than 90 degrees, it is acute.
if angle is greater than 90 degrees, it is obtuse.
if angle is equal to 90 degrees, it is right angle.
Since the angle measures greater than 90 degrees, it falls within the range of an obtuse angle.
Therefore, the correct classification for angle A is obtuse.

6x + 6y=-6
5x + y=-13
Answer:
(-3, 2)
x=-3, y=2
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation. and thats how you get your answer :)
The value of x is -3 and value of y is 2.
The given equations are:
6x + 6y=-6 ..(1)
5x + y=-13...(2)
From equation (2)
y=-13+5x..(3)
Plug in equation in equation (1):
6x + 6(-13+5x)=-6
6x-78+30x=-6
24x=-72
Divide both sides by 24:
x=-72/24
x=-3
Now put x=-3 in equation (2):
5(-3) + y = -13
-15 + y = -13
y = -13 + 15
y = 2
Hence, the value of x is -3 and value of y is 2.
