For which equation is g = 0 not the solution?
12 g = 0
3 g = 30
g + 8 = 8
9 g = 0
Answer:
3g = 30
Step-by-step explanation:
Well, lets check each one to see if any leaves g = 0
12g = 0 (Given)
÷12 ÷12 (Get "g" on its own)
g = 0 (0 ÷ 12 = 0)
We know it is not this one since g = 0
3g = 30 (Given)
÷3 ÷3 (Get "g" on its own)
g = 10 (30 ÷ 3 = 10)
This is our answer since g = 10 in this equation, and not g = 0 we know that this is our equation.
Just in case, I will do the other options just not as in-depth!
g + 8 = 8
-8 -8
g = 0
9g = 0
÷9 ÷9
g = 0

Marissa had a $25 gift card for Roosters on Oxford. Each morning she purchases her $3 vanilla latte. Write an equation in slope- intercept form where y represents the amount of money on the card, after x visits.
Answer:
Y=3/1x+25
Step-by-step explanation: I believe this is correct. I was doing this a while ago so I might have it wrong. Y Is the money on the card, m, or 3/1 is the slope. B is the Y-intercept, which is 25.

Answer:
3
Step-by-step explanation:
The unit rate is a rate with 1 in the denominator. The unit rate for this equation would be how much money he makes in one hour. So, to find the unit rate plugin 1 for r and solve for g. One times three (1*3) is equal to 3; therefore, that is the unit rate.

The Pythagorean Theorem is a^2+b^2=c^2. In this case. a=10, b=y, and c=2+y.
So, [tex](2+y)^{2}=10^{2}+y^{2}[/tex].
(b)
Using the equation (2+y)^2=10^2+y^2, solve for y.
(2+y)^2=10^2+y^2Square it, 4+4y+y^2=100+y^2Subtract y^2, 4+4y=100Subtract 4, 4y=96Divide by 4, [tex]y=24[/tex].There is a 3 out of 20 chance that you can win a game. How many "wins" would you predict if you played the game 50 times?
Answer:
7.5
Step-by-step explanation:
The probability of winning = 3 out of 20 ;
P(winning) = 3/20
Predicted Number of winnings if game is played 50 times ;
P(winning) * number of games played
(3 /20) * 50
0.15 * 50
= 7.5
Predicted Number of winnings = 7.5

What is Percentage?The percentage formula is used to calculate the amount or percentage of anything in terms of 100. Percentage indicates "per hundred" in its most basic form. The percentage formula is used to express a number between zero and one. It is a number that is expressed as a fraction of 100. It is represented by the sign% and is mostly used to compare and find ratios.
Given:
The percent for Video Game= 25%
and, percent for Research = 5%
So, 25% of 30 = 25 / 100 x 30 = 7.5
5% of 30 = 5/100 x 30 = 1.5
So, the the number of hour spend on more on Video game
= 7.5 - 1.5
= 6 hour

Answer:
x = 36 degrees
y = 48 degrees
Step-by-step explanation:
The two given triangles are congruent
Hence, we can say that the interior angles are equal
We shall use the angle markings on each of the triangles
Using the markings, we can see that y is 48 degrees
Now, let us find the last angle measure of the first triangle
Mathematically, the sum of angles in a triangle is 180
Thus;
108 + 48 + A = 180
A = 180 - 48 - 108
A = 180 - 156 = 24
Now, the measure 2x-y is equal to this;
Hence;
2x -y = 24
2x = 24 + y
we have that y = 48
2x = 24 + 48
2x = 72
x = 72/2
x = 36 degrees
