A. An Algebraic Expression
Step-by-step explanation:
Since we have no equal sign in the problem, we know that it is an expression. An equation has an equal sign and another value so we can simplify to find the value of whatever variable we are working with. We also know that it is not anything numerical because we are working with variables. With this information we will see that the correct answer is A.

7+6(-8x-7)=3(-6x+8)+1
Answer:
x = -2
Step-by-step explanation:
7 - 48x - 42 = - 18x + 24 + 1
-35 - 48x = -18x + 25
-48x +18x = 25 =35
-30x = 60
x = -2
Answer:
-2
Step-by-step explanation:
7+6 (-8x-7)=3 (-6x+8)+1
7-48x-42= -18x+24+1
-48+18= 24+1-7+42
-30x=60 then divide the two sides with -30

If a gas tank can hold 30 gallons, how many gallons does it contain when it is three-fifths full?
Answer:
3/5 of 30 = (3/5)*30
3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/5
3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/5
3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/53/5 of 30 = 18
3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/53/5 of 30 = 18So when the tank is 3/5 full, there are 18 gallons in the tank.

Answer: a= [tex]g+2 / 2[/tex]
Step-by-step explanation:
g= -2 + 2a
>> -2+2a=g ( side change )
>> -2+2a +2 = g+2 ( adding 2 both side)
>> 2a = g+2
>> 2a /2 = g+2 /2 ( divide by 2 both side)
>> a= g+2 /2
What is the measure of the largest angle?
Answer:
90°
Step-by-step explanation:
The angles of a triangle have a sum of 180°.

Express the edge length of a cube as a function of the cube's diagonal length d. Then express the surface area and volume of the cube as a function of the diagonal length.
a. A function for the edge length of a cube is L(d) = _________________
b. A function for the surface area of a cube is Ald) = _____________
c. A function for the volume of a cube is V(d) = ________________
Answer:
Step-by-step explanation:
If L is the length of a side, the longest diagonal in the cube is
d = √(L² + L² + L²) = √(3L²) = L√3
meaning
a) L(d) = d/√3 = ⅓d√3
b) A(d) = 6(L(d))² = 6(⅓d√3)² = 6(⅟₉d²(3)) = 2d²
c) V(d) = (L(d))³ = (⅓d√3)³ = ⅟₂₇d³3√3 = ⅟₉d³√3

A pool charges $7 for 2 daily pool passes.
Which table could represent the situation?
Answer:
Therefore, membership of the pool will be less expensive until number of visits to the pool is one fourth of the membership.
Option B is the table which could represent the given situation.
What is a linear equation?A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.
According to the question
A pool charges $7 for 2 daily pool passes.
Using the linear equation y = mx + b
Substitute x = 2, y = 7
[tex]7 = 2m + b[/tex].....(1)
Substitute x = 4, y = 14
[tex]14 = 4m + b[/tex] .....(2)
Using elimination method
Subtract equation 1 from 2
[tex]14 - 7 = 4m - 2m + b - b[/tex]
[tex]7 = 2m[/tex]
[tex]m=\frac{7}{2}[/tex]
Substitute m = [tex]\frac{7}{2}[/tex] in equation 1
[tex]7=2(\frac{7}{2} )+b[/tex]
b = 7 - 7
b = 0
Substitute b = 0 in equation 1
7 = 2m
Similarly
14 = 4m
21 = 6m
28 = 8m
Hence, Option B is the table which could represent the given situation.
