you had $430 but you are spending $8 each day which algebraic expresion describes this situation where d represents the number of days
Answer: 430-8d
Step-by-step explanation:
you start with 430 dollars and you spend 8 a day. you multiply 8 by the number of days and subtract that from 430.
The algebraic expression that describes the situation is 430 - 8d.
Given,
You have $430 but you are spending $8 each day.
We need to find the algebraic expression that describes this situation where d represents the number of days.
What is an algebraic expression?An algebraic expression is an expression which is made up of variables and constants.
Find the algebraic expression.
Total amount = $430
Amount spend each day = $8
Let the number of days be denoted by: d
If $8 is spent daily then 8d represents the amount spent for d days.
Now,
$430 is the amount from which the money has to be spent so,
430 - 8d is the required algebraic expression.
Thus the algebraic expression that describes the situation is 430 - 8d.

Can someone Please! <3
Answer:
A= D , B=C
SO; angle D =102
A+B = 180
C+D=180
C+102=180 —> C = 180-102 = 78
So; C=78 , D=102I hope I helped you^_^
Answer:
angle C = 78
angle D = 108
Step-by-step explanation:
the measure of angle A is 102
To find the measure of angle C
let Angle C be x
102 + x = 180 (linear pair)
x = 180 -102
x = 78
angle C = 78
angle B = 78 (vertically opposite angles are equal)
angle D = 108 (vertically opposite angles are equal)

the measure of the angles of a triangle are shown in the figure below. solve for x.
Answer:
[tex]\boxed {\boxed {\sf x= 12}}[/tex]
Step-by-step explanation:
We are asked to solve for x. We are given a triangle and all 3 angles are labeled. We know that the sum of the angles in a triangle must be 180 degrees. Therefore, the given angles: 81, 57, and (2x+18) must add to 180. We can set up an equation.
[tex]81+57+ (2x+18)= 180[/tex]
Now we can solve for x. Begin by combing like terms on the left side of the equation. All the constants (terms without a variable) can be added.
[tex](81+57+18)+2x=180[/tex]
[tex]156+2x=180[/tex]
We will solve for x by isolating it. 156 is being added to 2x. The inverse operation of addition is subtraction. Subtract 156 from both sides of the equation.
[tex]156-156+2x=180-156 \\2x=180-156 \\2x= 24[/tex]
x is being multiplied by 2. The inverse operation of multiplication is division. Divide both sides by 2.
[tex]2x/2= 24/2 \\x= 24/2 \\x=12[/tex]
In this triangle, x is equal to 12.
Answer:
x° = 12°Step-by-step explanation:
❁ Hello! ❁
The sum of the measures of the angles of a triangle is 180°.
81° + 57° + (2x + 18)° = 180°
138° + (2x + 18)° = 180°
(2x + 18)° + 138° = 180°
2x + 18° = 180° - 138°
2x + 18° = 42°
2x = 42° - 18°
2x = 24°
x° = 24° ÷ 2
x° = 12°
Success! ☺️

12. Find three consecutive even integers such that
the sum of the smallest integer and twice the
median integer is 20 more than the largest
integer.
Answer:
10, 11, 12
Step-by-step explanation:
Hi there!
Let x be equal to the smallest integer.
Let x+1 and x+2 be equal to the consecutive integers.
We're given that:
⇒ smallest integer + 2 × middle integer = 20 + largest integer
Construct an equation:
[tex](x)+2(x+1)=20+(x+2)[/tex]
Combine like terms:
[tex](x)+2(x+1)=20+(x+2)\\x+2x+2=20+x+2\\3x+2=22+x\\2x=20\\x=10[/tex]
Therefore, the smallest integer is 10.
This makes the consecutive integers 11 and 12.

Answer:
12 minutes.
Step-by-step explanation:
If it took 1.5 minutes to run 1/8 of a mile, you need to multiply both numbers by 8 (whole number) to get your answer.
a. 1/8 × 8/1 = 8/8 or ONE WHOLE MILE
b. 1.5 × 8/1 = 12
The mile is fractioned into 8 parts, multiply by 8 to get a whole mile.
The difference of a positive integer and an integer that is greater than it
Answer: Positive integers are all the whole numbers greater than zero: 1, 2, 3, 4, 5, ... . Negative integers are all the opposites of these whole numbers: -1, -2, -3, -4, -5, …. ... If an integer is greater than zero, we say that its sign is positive. If an integer is less than zero, we say that its sign is negative
so 8 9 10 is positive and -8 -9 -10 is negative
they cancel each other out like 8+-8 = 0 and -8+4=-4

Year 8 maths Finding the rule using a table of values
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, a) and (x₂, y₂ ) = (1, b)
m = [tex]\frac{b-a}{1-0}[/tex] = b - a
y = (b - a)x + c
(a)
with coefficient of x being b - a
(b)
The line crosses the y- axis at (0, a ) ⇒ c = a
y = (b - a)x + a

Included sides AE and BE need to be given as congruent to prove that triangle AEC is congruent to triangle BED by the Angle-Side-Angle (ASA) Congruence Theorem.
According to the Angle-Side-Angle (ASA) Congruence Theorem, if two angles and an included side of a triangle is congruent to corresponding two angles and an included side of another triangle, both triangles can be proven to be equal or congruent to each other.
We are know the following from the given image:
<AEC = <BED (vertical angles are congruent)
<EAC = <EBD (congruent angle)
This implies that two angles (<AEC and <EAC) in triangle AEC are congruent to two corresponding angles (<BED and <EBD) in triangle BED.
Therefore, to prove that both triangles are congruent by ASA, we need to be given that the included sides AE and BE are congruent.

Answer:
Step-by-step explanation:
MO bisects ∠LMN.
⇒ ∠LMO = ∠NMO
⇒ ∠LMN = 2 * ∠LMO
6x - 28 = 2* (x +34)
6x - 28 = 2*x + 2*34
6x - 28 = 2x + 68
Add 28 to both sides
6x = 2x + 68 + 28
6x = 2x + 96
Subtract 2x from both sides
6x - 2x = 96
4x = 96
Divide both sides by 4
x = 96/4
x = 24
∠LMO = x + 34 = 24 + 34 = 58
∠MNO = ∠LMO
∠MNO = 58°
