Answer:
My answer is = 9 cannot equal 12. There are no variables present in this equation, so what are you solving for?
Step-by-step explanation:
On the right you would use distributive property and on the left you would just simply add and subtract.
However, you cannot equal it to zero either because there are no variables nor exponents.
The perimeter of a rectangle is 36 cm. The length is 10 cm longer than the
width. What are the length and width of the rectangle?
Answer:
Below
Step-by-step explanation:
X(x+10)=36
x= -5+sqrt 61 or-5-sqrt 61

What is the quotient of 5 7 ÷ 5 14 ?
Answer:
= 57 / 514 (Decimal: 0.110895)Step-by-step explanation:
57 / 514
= 57 / 514
(Decimal: 0.110895)
And if that is not what you are looking for here:
Rewrite the equation as
x /14 = 5/ 7 . x/ 14 = 5/ 7
Multiply both sides of the equation by
14.14 ⋅ x /14 = 14 ⋅ 5 /7
Simplify both sides of the equation.
Tap for fewer steps...
Cancel the common factor of 14 .
Cancel the common factor.
14 ⋅ x /14 = 14 ⋅ 5 /7
Rewrite the expression.
x = 14 ⋅ 5 /7
Simplify 14 ⋅ 5/ 7 .
Cancel the common factor of 7 .
Factor 7 out of 14 .
x = 7 ( 2 ) ⋅ 5/ 7
Cancel the common factor.
x = 7 ⋅ 2 ⋅ 5/ 7
Rewrite the expression.
x = 2 ⋅ 5
Multiply 2 by 5 .
x = 10
Below are different ways students tried to start this problem. Which is correct?
(- 10) * (½) * (- 8)
A) (½) * - 8 = - ( - 8/16 )
B) (-10) * (½) = 5
C) -10 * (- 8) = 80
D) -8 * 2 = - 16
Answer:
C) -10 * (- 8) = 80
Step-by-step explanation:
(- 10) * (½) * (- 8)
Checking all the options
A) (½) * - 8 = - ( - 8/16 )
1/2 * - 8
= -8/2
= -4
(½) * - 8 = -4
(½) * - 8 = - ( - 8/16 ) Wrong
B) (-10) * (½) = 5
-10 * 1/2
= -10/2
= -5
(-10) * (½) = -5
(-10) * (½) = 5 Wrong
C) -10 * (- 8) = 80
-10 * (- 8)
= -10 × - 8
= + 80
-10 * (- 8) = 80 Correct
D) -8 * 2 = - 16
-8 * 2
= -16 correct but we don't have 2 in the expression so, it is wrong
The correct way to start solving the problem is C) -10 * (- 8) = 80
(- 10) * (½) * (- 8)
-10 * (- 8) = 80
80 * 1/2 = 80 / 2

how to turn a mixer number to a improper fraction
Step-by-step explanation:
1. keep the demoninator the same
2. to find the numberator, multiply the demoninator number by the whole number, and add the product of that with the numerator number.
example:
2 3/8 = 19/8
1. so, keep the denominator the same, which means that the denominator is 8
2. to find the numerator, you do:
8 times 2 = 16
16 + 3 = 19

The equation of the line is y = 2x - 2.
What is the point-slope form of a line?If m is the slope of the line that passes through the point (x₁, y₁), then the equation of the line is y - y₁ = m (x - x₁).
The graph of the line is given.
(1)
The line passes through points (2,2) and (6,10).
The slope of the line is:
m = (10 - 2)/(6 - 2)
m = 8/4
m = 2
(2)
The equation of the line with a slope of m =2 and passes through (2,2) is:
y - 2 = 2(x - 2)
y = 2x - 4 + 2
y = 2x - 2 (1)
(3)
The line passes through points (4,b) and (a,8), therefore, from equation (1):
b = 2(4) - 2
b = 6, and
8 = 2a - 2
2a = 10
a = 5
(4)
Substitute x = 0 into equation (1):
y = 2(0) - 2
y = -2
Hence, the equation of the line is y = 2x - 2.

Which of the following angles also measure 112 degrees? select ALL that apply
A. Angle 2
B. Angle 3
C. Angle 4
D. Angle 5
E. Angle 6
F. Angle 7
Answer:
Step-by-step explanation:
The answer will be c if not then a
The value of the angles are ∠2 = 68, ∠4 = 68, and ∠3 = 112.
What is an angle?The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
Supplementary angles are the angles having a sum of 180 degrees.
∠1 + ∠4 = 180
112 + ∠4 = 180
∠4 = 180 -112= 68°
Vertically opposite angles are always equal.
∠4 = ∠2
∠2 = 68
Vertically opposite angles are always equal.
∠1 = ∠3
∠3 = 112°
Therefore, the value of the angles are ∠2 = 68, ∠4 = 68, and ∠3 = 112.

Solve the equation for Y: 3x + 1/5 y equals 7
Answer:
y = 35- 15x
Step-by-step explanation:
To solve for y, first isolate the term containing y.
1/5y = 7 - 3x
Multiply both sides by 5 to cancel out the fraction.
5(1/5y) = 5(7 - 3x)
This will result in:
y = 35- 15x
Do not forget to distribute the 5 when multiplying.
The equation is now solved for y.

Isadora rents an apartment for $1,000 a month and has a year's lease.
She owns a car that is worth $14,700. She has a savings account of $4,750 and a
credit card balance of $825. What is her net worth?
Step-by-step explanation:
So let's say this is for the year and were working out the amount she spent.
She starts off with paying $1,000 for rent.
Then she owns a car that is $14,700.
Her savings account is 4,750 and Credit card balance is 825{not sure if that's what she is has to spend or if its tax so I'll do two ways}.
1,000
4,750
825
+14,700
21325
Her total would be $21,325 taking it that 875 was a tax.
if not the answer would be $20,450.
if the car does not have a tax just minus the 14,700 from either of them two numbers.
Amount of Isadora's net worth is $6,625.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To find Isadora's net worth, we need to subtract her total debts from her total assets.
So,
Her total assets.
Car worth = $14,700
Savings account balance = $4,750
So, her total assets.
= $14,700 + $4,750
= $19,450
Her total debts.
Credit card balance = $825
Monthly rent for 1-year lease = $1,000 x 12 = $12,000
So, her total debts.
= $825 + $12,000
= $12,825
To find her net worth, we subtract her total debts from her total assets.
So,
Net worth = Total assets - Total debts
Net worth = $19,450 - $12,825
Net worth = $6,625
Therefore,
Isadora's net worth is $6,625.

32 days is my final answer
Step-by-step explanation:
Leon drove from his house in Cincinnati to his sister’s house in Cleveland, a distance of 252 miles. It took him 4.5 hours. For the first half-hour, he had heavy traffic, and the rest of the time his speed was five miles per hour less than twice his speed in heavy traffic. What was his speed in heavy traffic?
Answer:
Speed in heavy traffic is 32 miles per hour
Step-by-step explanation:
Total distance = 252miles
Total time = 4.5hours = 4 hours + 30minutes
Let the speed in heavy traffic = x
distance = time * speed
First half hour
D1 = 0.5*x
The speed after the traffic = 2x - 5
D2= 4* (2x - 5)
Total distance = D1 + D2
[tex]\frac{x}{2}[/tex] + 8x - 20 = 252
[tex]\frac{17x}{2}[/tex] = 272
x = [tex]\frac{272}{17}*2[/tex]
x = 32 miles per hour
