Answer:
G= 1/6p -15
Step-by-step explanation:
Let's solve for g.
p=6g+90
Step 1: Flip the equation.
6g+90=p
Step 2: Add -90 to both sides.
6g+90+−90=p+−90
6g=p-90
Step 3: Divide both sides by 6.
6g/6 = p−90/6g
=1/6p−15

Can someone explain how to work this out please ?
Answers
Answer:
x=4
Step-by-step explanation:
f(x) = (x-2)^5 +3
Let f(x) = 35
35 = (x-2)^5 +3
Subtract 3 from each side
35-3 = (x-2)^5 +3-3
32 = (x-2)^5
Take the fifth root of each side
32 ^ (1/5) = (x-2)^5^ 1/5
2 = x-2
Add 2 to each side
2 +2 = x-2+2

Answers
Answer:6:45
Step-by-step explanation:
Answer:
x = 30
Step-by-step explanation:
a ratio is just a fraction
9:45 = 9/45
6:x = 6/x
now you have 9/45 = 6/x
cross multiply:
9 * x = 45 * 6
9x = 270
divide both sides by 9
9x/9 = 270/9
x = 30

The Nguyen family is traveling cross-country, driving 300 miles each day. Let 2 represent the number of days in the trip and let y represent the total number
of miles driven.
Write an equation to model their trip.
Enter the correct equation in the box.
Answers
Step-by-step explanation:
y = Total number of miles driven
= Number of days * Number of miles per day
= (x) * (300).
Therefore the equation is y = 300x.
When x = 2, y = 300(2) = 600.
The Nguyen family drove 600 miles during the 2 days.
How many cubic centimers of water can this paper cone cup hold?
Answers
Answer:
B: 48π cubic centimeters
Step-by-step explanation:
A: 216π cubic centimeters
B: 48π cubic centimeters
C: 144π cubic centimeters
D: 192π cubic centimeters
Volume of the paper cone cup = 1/3πr²h
Diameter = 8 cm
Radius, r = diameter / 2
= 8 cm / 2
= 4 cm
Height, h = 9 cm
Volume of the paper cone cup = 1/3πr²h
= 1/3 × π × 4² × 9
= 1/3 × π × 16 × 9
= (1 × π × 16 × 9) / 3
= 144π / 3
= 48π cm³
Volume of the paper cone cup = 48π cm³

solve the system by substitution y=x-8 y=2x-14
Answers
Answer:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:
(6,-2)
Equation Form:
x=6,y=-2
Step-by-step explanation:
The value of x is 6 and y is -2.
What is Substitution Method?The algebraic approach to solving simultaneous linear equations is known as substitution method. The value of one variable from one equation is substituted in the second equation in this procedure, as the name implies.
When a variable (or set of letters) in an algebraic statement is substituted, its numerical value is used instead.
Given:
y=x-8..................(1)
y=2x-14.................(2)
Substitute the value of y from equation (1) to equation (2), we get
x-8 = 2x- 14
2x - x = -8 + 14
x = 6
and, y= x-8
y= 6-8
y= -2.
Hence, the value of x is 6 and y is -2.

Solve for x:
7x = 105
Answers
Answer:
X=15
Explanation: You have no like terms to combine and are at the last step of the algebraic equation. So, you would divide 7 on both sides. 7 by 7 cancels it out and 105 divided by 7 equals 15. Hope this helps ^-^.
The solution to the equation 7x = 105 is x = 15.
We have the equation: 7x= 105
To solve for x in the equation 7x = 105, we need to isolate x on one side of the equation.
Divide both sides of the equation by 7:
(7x)/7 = 105/7
Simplifying:
x = 15
Therefore, the solution to the equation 7x = 105 is x = 15.
