Answer:
g = 6
Step-by-step explanation:
5.2g + 10 = 2.2g + 28 (Given)
3g + 10 = 28 (Subtracted 2.2g on both sides)
3g = 18 (Subtracted 10 on both sides)
g = 6 (Divided 3 on both sides)
To check to make sure you are correct, simply substitute your answer for g:
5.2(6) + 10 = 2.2(6) + 28
31.2 + 10 = 13.2 + 28
41.2 = 41.2
You'll know you're correct if they both equal the same. In this case, the solution works.

Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
Equality PropertiesSolving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
a + 4b = -4
a + 10b = -16
Step 2: Rewrite Systems
a + 4b = -4
Subtract 4b on both sides: a = -4 - 4bStep 3: Redefine Systems
a = -4 - 4b
a + 10b = -16
Step 4: Solve for b
Substitution
Substitute in a: -4 - 4b + 10b = -16Combine like terms: -4 + 6b = -16Isolate b term: 6b = -12Isolate b: b = -2Step 5: Solve for a
Define equation: a + 4b = -4Substitute in b: a + 4(-2) = -4Multiply: a - 8 = -4Isolate a: a = 4An official for a regional baseball league examines attendance data for teams in the league.

Which expressions are equivalent to 6a(5+d) ?
SELECT EACH CORRECT ANSWER (theres more than 1)
30a+6ad
(6a⋅5)+(6a⋅d)
11a + d
30a+(6a⋅d)
30ad
Answer:
first, second and fourth
Step-by-step explanation:
If you use distribution,
6a(5+d) is the same as
6a(5) + 6a(d)
Multiplied = 30a + 6ad
So it's the 1st 2nd and fourth choice.
1st is stated above when multiplied out and combined.
2nd is after distribution.
4th choice is basically combination of 1 and 2 where one is combined (first term) and the second one just set up to be multiplied.
It cannot be third because you are multiplying the factors and not adding so you cannot have 11a.
It cannot be last choice because you have different types of terms that cannot be combined (one with a alone and one with ad)
Answer:
(6a*5) + (6a*d)
30a + 6ad
30a + (6a*d)
Step-by-step explanation:
Hope you ace your test!

A piecewise function is represented by the graph below.
On a coordinate plane, a piecewise function has 2 lines. The first line is made up of 2 lines. One line goes from (negative 5, 3) to (negative 1, negative 1) and then goes up to a closed circle at (1, 1). The second line has an open circle at (1, 2) and then continues up through (3, 4).
What is the domain for the piece of the function represented by f(x) = x + 1?
9514 1404 393
Answer:
x > 1
Step-by-step explanation:
The open dot at (1, 2) tells you that point is not in the domain. Apparently, the piece represented by f(x) = x+1 extends to +∞ from x = 1.
the domain of the piece is x > 1
Answer:
x>1

Which equation has infinitely many solutions?
A.
-5(x + 2) = -4x- 12 - X + 2
B.
3x- 4 + 2x = 5(x-4)
c. 5(x + 7) = -5(x-7)
D
6x+ 2 - X=-2x - 2 + 7x
Answer:
A. -5(x + 2) = -4x - 12 - x + 2
Step-by-step explanation:
The equation that has infinitely many solutions will be the same on both sides.
A is the correct answer.
Simplify the equation by distributing -5 and adding like terms:
-5(x + 2) = -4x - 12 - x + 2
-5x - 10 = -4x - 12 - x + 2
-5x - 10 = -5x - 10
So, this equation is the same on both sides and will have infinitely many solutions.
A is the correct answer.
Answer:
A has infinitely many solutions
Step-by-step explanation:
Once you distribute A you get
-5x-10= -4x-12-x+2
Once you simplfy all that you get
-5x-10= -5x-10
You can check this by putting in a random number and both sides will be equal.

Suppose we want to test to see if a roulette wheel is balanced. The wheel is spun 100 time resulting in 58 red outcomes. Is this evidence that the roulette wheel is out of balance
Solution :
Here, [tex]$ \hat p$[/tex] = sample proportion of red outcomes
[tex]$ \hat p =\frac{58}{100}$[/tex]
[tex]$ \hat p$[/tex] = 0.58
So we have to test,
[tex]$H_0 : p = 0.5$[/tex]
V/S [tex]$H_a: p \neq 0.5 $[/tex]
The test statistic is
[tex]$z = \frac{\hat p - p}{\sqrt{\frac{p(1-p)}{n}}}$[/tex]
[tex]$z = \frac{0.58 - 0.5}{\sqrt{\frac{0.5(1-0.5)}{100}}}$[/tex]
[tex]$=\frac{0.08}{0.05}$[/tex]
= 1.600
P value using the z table is 0.110
So P value greater than 0.05
Therefore, there is no evidence that roulette wheel is out of balance.

7 + k/4= 9
what does k=?
Answer: k=8
Step-by-step explanation: So your equation is 7+k/4=9. Remember, the goal of this problem is to isolate the k. The first thing you should do is subtract 7 from both sides. You should get k/4=2. Then, multiply both sides by 4 to isolate the k. You should get k=8. Hope this helps!
