A. x= -1
B. there are infinitely many solutions
C. x= 1
D. x = -7/13
Solve the equation for the indicated variable.
Answer:
Option A
Step-by-step explanation:
[tex]D=3ef^2\\[/tex]
we need to make e the subject of the formula so here goes,
On the right side 3 is being multiplied by ef^2 so when it moves to the left side it will divide
[tex]\frac{D}{3}=ef^2[/tex]
now f^2 is also being multiplied by e on the right side so when it moves to the left side it will divide
[tex]\frac{D}{3f^2}=e\\\\[/tex]

Solve for x given 16 = 2x + 2( 4+ x)
Answer:
x=2
Step-by-step explanation:
16=2x+2(4+x). First distribute the 2 into the parenthesis (4+x):
16=2x+8+2x. Now combine the like terms:
16=4x+8. Now to get 4x by itself, subtract 8 to the left:
8=4x. Solve for x by dividing by 4:
2=x

8x + 10y = 70
Please answer!
ANSWER:
y=-4/5x+7
Subtract 8x from both sides of the equation.
10=70y −8x
Divide each term by 10 and simplify
cancel the comman factor to Cancel the common factor.
which is 10
Divide y by 1
Simplify
70 -8x
y= --- + --------
10 10
write in y=mx+b form
so it y=-4/5x+7
A number n is less than or equal to -7 or greater than 12.
Inequality: [ ] or [ ]
Graph the inequality.
Answer:
N ≤ -7 N > 12
Step-by-step explanation:
The inequality for the given statement is n≤-7 or n>12.
The given statement is a number n is less than or equal to -7 or greater than 12.
What is an inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values.
Now the inequality for the given statement is n≤-7 or n>12.
Graph for the obtained inequality is plotted, given below.

Compare the quotient to the estimate
Evaluate the expression using mental math and the division algorithm.
Answer:
The given expression for the division is 23,529/23
Evaluating the expression using mental math gives;
23,529/23 = (23,000 + 230 + 230 + 23 × 3)/23 = 1000 + 10 + 10 + 3 = 1,023
Evaluating the expression using the division algorithm states as follows;
When an integer a is divided by another integer n, then we can find the numbers q and r such that a = b·q + r and a/b = q + r/b, where, b > 0, and 0 ≤ r ≤ b
Where;
q = The quotient
r = The reminder
Therefore, we have;
23,529 = 23×q + r
Given that 23 × 1029 = 25,529, we have
23,529 = 23 × 1029 + 0
Therefore, q = 1029, and r = 0

what is the nth term for 8, 16,26,38, 52, 68, 86
The missing term is 106.
Step-by-step explanation:
The given sequence are:
8, 16, 26, 38, 52, 68, 86, ?
To find, the missing term =?
The pattern follow:
Previous number + 8, Previous number + 10, Previous number + 12, Previous number + 14, Previous number + 16, Previous number + 18,.....
16 = 8 + 8 = 16
26 = 16 + 10 = 26
38 = 26 + 12 = 38
52 = 38 + 14 = 52
68 = 52 + 16 = 68
86 = 68 + 18 = 86
Similarly,
? = 86 + 20 = 106
Hence, the missing term is 106.

Answer:
15
Step-by-step explanation:
[3(9)-(-3)]/2
30/2=15
Answer:
Your answer should be 15.
Step-by-step explanation:
3 times 9 is 27. When you subtract a negative number they combine to sign to be a + so you would get 30 since you would be adding 3. You would then divide 30 by two to get 15! <3
a triangle has the side 7+x and a side of 15 find the other side
Answer:
x = 8
Step-by-step explanation:
Well, you didn't specify if it was an isosceles triangle or if it was equal or anything so we're going to assume it is.
So since both sides are equal 7+x=15
7(-7)+x=15(-7)
x=8
Plug in 8 as x to check
7 + 8
15
Which would equal the other side.

Solve the following inequality.
-4(1 - 5a) > -124
Answer:
a>−6
Step-by-step explanation:
−4(1−5a)>−124
Step 1: Simplify both sides of the inequality.
20a−4>−124
Step 2: Add 4 to both sides.
20a−4+4>−124+4
20a>−120
Step 3: Divide both sides by 20.
20a/20> −120/20
a>−6
