(7x+40)+(6x+43)=180 x? Z?
[tex](7x + 40) + (6x + 43) = 180\\7x + 40 + 6x + 43 = 180\\7x + 6x = 180 - 40 - 43\\13x = 97\\x = \frac{97}{13}[/tex]
I'm not sure what you mean by Z but x is [tex]\frac{97}{13}[/tex]

Solve for g.
C=1/2gq
Answer:
[tex] g = \frac{2c}{q}[/tex]
Step-by-step explanation:
[tex]c = \frac{1}{2} gq \\ 2c = gq \\ \huge \red{ \boxed{ g = \frac{2c}{q} }}[/tex]
Answer:
g = 2C/q
Step-by-step explanation:
C * (2) = 1/2gq * (2)
2C / q= gq / q
2C/q = g

Which statement about the graph is true? 7 6 5 2 3 2 1 1 2 3 4 5 6 7 8 x O The graph shows a proportional relationship because it is a line, and the difference between each point is the same. The graph shows a proportional relationship because it is a line, and each x-value isha multiple of 2. O The graph does not show a proportional relationship because each point written as a ratio gives a different value.
Answer:
I think but it can also be the first one

Answer:
[tex]\boxed{k = -6}[/tex]
Step-by-step explanation:
[tex]13 +\frac{k}{3} =11[/tex]
→ Multiply everything by 3
[tex]39 + k = 33[/tex]
→ Minus 39 from both sides to isolate k
[tex]k = -6[/tex]
A ____ is written as an if-then statement A.conjecture B.counterexample C.conditional D.negation
Answer: C
Definition of a conditional:
A conditional statement is a statement that can be written in the form “If P then Q,” where P and Q are sentences. For this conditional statement, P is called the hypothesis and Q is called the conclusion. Intuitively, “If P then Q” means that Q must be true whenever P is true.
Can anybody please help me out with this problem I would really appreciate it so much . Please and thank you
"Supplementary" angles add up to 180°.
Opposite angles are supplementary, so . . .
(12x - 4) + (19x - 2) = 180°
Clear the parentheses: 12x - 4 + 19x - 2 = 180°
Add up all the x's on the left side: 31x - 4 - 2 = 180°
Add up the plain old numbers on the left side: 31x - 6 = 180°
Add 6 to each side: 31x = 186°
Divide each side by 31 : x = 6°
Well ! Now that you know that x = 6° . . .
Angle EPC is (12x - 4)°
That's (12·6 - 4)°
Which is (72 - 4)°
Which is 68°

. When the process of solving a linear inequality results in the variable being eliminated with a false statement remaining, what does this mean about the solution set of the inequality?
Answer:
No Solution
Step-by-step explanation:
When we solve linear inequalities using any one the methods such as
1) Elimination or
2) Substitution
And we get the variable eliminated with a false statement remaining, this means there is no solution.
In other words the solution does not exist or the solution is not possible in the given range or the values given are false.
But when the values are true we get a solution for the variable solved.
In the elimination method we eliminate the same terms by addition or subtraction after making them equal.
And the substitution method requires putting the values of one variable in place of another.

If 9 (x) = – 5x2 – 4x + 19 find f (–3)
Answer:
- 14
Step-by-step explanation:
[tex]f(x) = - 5 {x}^{2} - 4x + 19 \\ plug \: x = - 3 \\ f( - 3) = - 5 {( - 3)}^{2} - 4( - 3) + 19 \\ f( - 3) = - 5 \times 9 + 12 + 19 \\ f( - 3) = - 45 + 31 \\ f( - 3) = -14[/tex]

$20,000 was invested in a 3-year simple interest money market account. After 3 years,
the account balance was $32,000.
What was the interest rate for the account?
Step-by-step explanation:
Amount = principal + S. I.
S. I. = p * t * r / 100
32000 = 20000 + 20000 * 3 * r / 100
12000 = 600 r
r ( Rate of interest) = 20 %
Of 150 goldfish in the fish pound, 27 are red. What percentage of goldfish are red?

4x + y = 2
I need to solve the literal equation for y.
Answer: y=2−4x
Step-by-step explanation:
When solving for y in this problem(4x+y=2) we need to get y by itself in the equation. To do this we need to move 4x over to the right side of the equation. To do this we subtract, 4x from both sides of the equation.
