Answer:
78Explanation:
acb − (a + d)
a = -2b = 3c = -12d = -4= (-2) (-12) (3) - (-2 + -4)
Parenthesis: (-2 + -4) = -6
= (-2) (-12) (3) - (-6)
Simplify (-2) (-12) (3): 72
72 - (-6)
78if a=−2 , b=3 , c=−12 , and d=−4 for expression acb−(a+d) then its value is 78.
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is acb−(a+d)
a times c times b minus a plus d
The values of a, b, c and d are given.
In the given expression a,b,c and d are variables and plus and minus are operators
a=−2 , b=3 , c=−12 , and d=−4 .
Substitute these values in expression acb−(a+d)
(-2)(-12)(3)-(-2+(-4))
When minus is multiplied two times we get positive, if three times we get negative
72-(-2-4)
72-(-6)
Seventy two plus six
72+6
Seventy eight
78
Hence if a=−2 , b=3 , c=−12 , and d=−4 for expression acb−(a+d) then its value is 78.

Prompt: Sasha wants to go to the department store this Saturday for the big sale. She has saved $45, received $75 from birthday gift cards, and will receive $125 on Friday from work. Her mother reminds Sasha of the $39 she owes her for the last pair of jeans. Sasha also needs to put $50 in her savings. The sale has $40 jeans at 20 percent off and T-shirts on sale for 3 for $15.99. How many pairs of jeans and T-shirts can Sasha purchase? Show or explain how you got your answer.
Answer:
Step-by-step explanation:
Given that :
Inflow for Sasha = $(45 + 75 + 125) = $245
Outflow = $(39 + 50) = $89
Amount shasha can spend on sale :
$(245 - 89) =$156
T- shirt sales = 3 for $15.99
Pair of Jeans = (1 - 0.2) = 0.8 * $40 = $32
3 pairs of jeans
12 T-shirts at 3 for $15.99
3 jeans = 3 * $32

Answer:
m∠3 = 78
Step-by-step explanation:
Okay, since a triangle has 3 sides, we only need to find the measure of m∠3.
A triangle is made up of 180 degrees, so we can make an equation with 180 as what the equation is equal to.
Since m∠1 = 70, and m∠2 = 32, we will add those together with a variable x,
70+32+x=180
70 plus 32 is 102.
102+x=180
To get 102 to the other side we need to do the opposite of addition, which is subtraction.
180-102=78
So the answer is 78.

Quadrilateral ABCD is similar to quadrilateral A'B'C'D'. Select all statements
that must be true.
there is 4 opinion in the photo
Answer:
Option 1, 2, and 4 are correct. Option 3 is incorrect.
We can conclude that the ratios →
A'B'/AB = A'C'/AC AD/A'D' = BC/B'C' AB/CD = A'B'/C'D'are true.
What is similarity of triangles?Two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor.
Given is Quadrilateral ABCD is similar to quadrilateral A'B'C'D'.
If Quadrilateral ABCD is similar to quadrilateral A'B'C'D', then we can say that all the sides and diagonals will be resized by the same scale factor of [K]. So, we can say that -
A'B'/AB = A'C'/AC is true
AD/A'D' = BC/B'C' is true
AB/CD = A'B'/C'D' is true
BD/B'D' = C'D'/CD is false.
Therefore, we can conclude that the ratios →
A'B'/AB = A'C'/AC AD/A'D' = BC/B'C' AB/CD = A'B'/C'D'are true.

Answer:
C (.35) on edge2021! :)
Step-by-step explanation:
for this problem we use the formula P(X = k) = (n over k)p^k(1-p)^n-k and in this case,
k = 5
n = 6
p = .90
and (n over k), n choose k, is calculated by (n! / k!(n-k)!) or just look up "6 choose 5" and you'll figure out that it's equal to 6.
so you end up with P(X = 5) = 6(.90)^5(1-.90)^6-5 which will give you .35 when put in a calculator.
