Answer/Step-by-step explanation:
A. (7 x 10) = 70
(3 x -15) = -45
70 + -45 = 25
B. (2 x 10) = 20
(8 x -15) = -120
20 + - 120 = - 100
C. (5 x 10) + ( 5 x -15) or 5 x (10 + -15)
5 x 10 = 50
5 x -15 = -75
50 + -75 = -25
pleeaseeeeeeeeeee hellpppppp

How is an inequality different from an equation? Give a real-world scenario in which you would write an inequality rather than an equation.
HELPPPPPPPPPPPPPPPP PLEASEEEEEEEEE
Answer: An equation is a mathematical statement that shows the equal value of two expressions while an inequality is a mathematical statement that shows that an expression is lesser than or more than the other. An equation shows the equality of two variables while an inequality shows the inequality of two variables.
Step-by-step explanation: Hope this helps! :D
one scenario can be that if you have less than or equal amount of money only then you can buy a certain thing......e.g : if price of a game is 40....then i should have money equal to or more than fourty to buy the game......
money>=40

Standard to Slope Intercept Form.
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

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.

What does each variable in the Slope-Intercept Form equation represent?
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.

Round to a one-digit arithmetic fact. Estimate the quotient.
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

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 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

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
