Step-by-step explanation:
The value of the given expression at z = 5 is 45.
What is an Algebraic expression?An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.
The variable part of an algebraic expression can never be added or subtracted from the constant part.
The given algebraic expression is 3z²− 6z.
The value of the expression at z = 5 is given as follows,
3z²− 6z
Substitute z = 5 to obtain,
3 × 5²− 6 × 5
= 75 - 30
= 45
Hence, the given expression can be simplified as 45.

i need help finding n
-5n-8(1+7n)=-8
Answer:
Step-by-step explanation:
-5n-8-56n=-8 i did multiply the parenthesis
we will combine like terms
-5n-56n=-8+8
-61n=0
n=0
Answer:
n=0
Step-by-step explanation:
Remember your terms, whether it be PEMDAS / GEMS. I am going off GEMS so:
Grouping which are the parentheses; -8(1+7n) = -8-56n.
Next, combine your like terms:
-5n-8-56n=-8
-61n-8=-8
Add 8 to both sides, remember what you do to one side, you do to both sides.
-61n=0
Divide both sides by -61, your answer is 0.

Answer:
The missing angle is about 27.92°.
Step-by-step explanation:
This is a tangent equation, as there is no hypotenuse value. I'll use x as the missing angle.
tan(x) = opposite/adjacent
tan(x) = 20/38
tan(x) = 0.52631578947368421052631578947368
tan(x) ≈ 0.53
Now, we have to reverse.
tan⁻¹(0.53) = x
27.92358972 = x
x ≈ 27.92°
- 4x + y = 6

I need help on having a equations for the bunny and the cat.
Answer:
BUNNY: y = 3x + 5
CAT: y = 1x + 19
Step-by-step explanation:
Answer:
Bunny: 5 + 3y
Cat: 19 + y
Step-by-step explanation:
If we were trying to make an equation about the total number of pounds each animal weighs, we would take the current number of pounds for each animal and then add the product of the pounds they gain and the number of years.
Bunny: 5 + 3y
y - number of years
5 current pounds + 3 additional pounds * y
Cat: 19 + y
y - number of years
19 current pounds + 1 additional pound per year or just 'y'

Solve for x in the triangle below. Show your work!
2
84
Xº
Y
N
Answer:
x = 48°
Step-by-step explanation:
In the given triangle XYZ,
Sides XY and XZ are congruent.
Therefore, both the sides will be equal in measure.
By the definition of isosceles triangle,
"Opposite angles of the equal sides are equal in measure"
m∠Y = m∠Z = x°
m∠X = 84° [Given]
By the triangle sum theorem,
m∠X + m∠Y + m∠Z = 180°
84° + x° + x° = 180°
2x = 180 - 84
x = 48°
Therefore, measure of x = 48° will be the answer.

A price for pineapples is $5 for two pineapples the price for pineapple is $8 for four pineapples which store is offering the lowest price per pineapple explain your answer
Answer:
The first store
Step-by-step explanation:
Given data
Let us find the unit cost on each sale
A price for pineapples is $5 for two pineapples
Unit cost per pineapple
=5/2
=$2.5 per pineapple
price for pineapple is $8 for four pineapples
Unit cost
=8/4
=$2 per pineapple
Hence the first store offers the lowest price per pineapple $2.5

22% of the customers visiting the suit department of a certain store will purchase a suit, 30% will purchase a shirt and 28% will purchase a tie. 11% of customers purchase a shirt and a suit, 14% both a suit and a tie and 10% buy a shirt and a tie. Only 6% of customers buy all three items. Let A be the event that the customer purchases a suit, B the event that the customer purchases a shirt and C the event that the customer purchases a tie. If there are 1000 customers in the store one week, how many will purchase exactly one of these items
Answer:
If there are 1000 customers in the store one week, how many will purchase exactly one of these items
1000 CUSTOMERS*28%=280
Step-by-step explanation:
A The event that a persons buys a suit
B The event that a person buys a shirt
C The event that a person buys a tie
P(A)= 22%
P(B)= 30%
P(C)= 28%
P(AB)= 11%
P(AC)= 14%
P(BC)= 10%
P(ABC)= 6%
A u B u C Is the event that any item is bougth
AC u AC u BC Is the event that any two events occured
So the wanted probability is
P[(A u B u C )(AB u AC u BC)^c
P[(A u B u C )=P(AB)+ P(BC)+P(BC)
P[(A u B u C ) =0.22+0.30+0.28-0.11-0.14.-0.10+0.06
=0,51
0,51=+0,23+P[(A u B u C )(AB u AC u BC)^c
=0,28
1000 CUSTOMERS*28%=280

Which property allows you to write the equation −4y=−8 as the first step to solving the system of equations?
Question 3 options:
Substitution Property of Equality
Subtraction Property of Equality
Distributive Property
Division Property of Equality
The property that allows you to write the equation −4y=−8 as the first step to solving the system of equations is (a) Substitution Property of Equality
The equations are given as:
[tex]x - 3y = 1[/tex]
[tex]x + y = 9[/tex]
Make x, the subject in the second equation
[tex]x = 9 - y[/tex]
Substitute 9 - y for x in the first equation
[tex]9 - y - 3y = 1[/tex]
Collect the like terms
[tex]-y -3y =1 - 9[/tex]
Evaluate the like terms
[tex]-4y =- 8[/tex]
Hence, the property is (a) Substitution Property of Equality
