Use the exchange rate £1 = $1.36 to convert $68 into £.

Step-by-step explanation:

2(x+7)=72 no, because this only changes the value on the right side. so this equation is not about the same equality anymore.

x+7=18 yes, because both sides were transformed by the same operation (division by 2). the equality is still maintained.

2x+7=36 no, because 2x+7 is NOT equal to 2(x+7). resolving 2(x+7) is 2x+14.

x+14=36 no, because again, x+14 is NOT equal to 2(x+7).

(2×x) + (2×7) = 36 yes, because the left side is a valid transformation of 2(x+7).

2x+14=36 yes, because the left side is a valid transformation of 2(x+7).

Step-by-step explanation:

if the value of (a) is negative, then (b) being greater than 1 would make the answer smaller. if (a) is positive, then (b) would have to be greater

Answer:

greater than 1

Step-by-step explanation:

must be greater than 1.

WHY?:

a is possitive = +a

b can't be negative or zero

if b is equal to 0

then a * 0 = 0

0 is lesser than one

Step-by-step explanation:

convert 40 minutes to hours

[tex] \frac{40 \: minutes}{1} \times \frac{1 \: hour}{60 \: minutes} = \frac{40}{60} = \frac{2}{3} hour[/tex]

multiply to find the number of cars per hour

[tex] \frac{2}{3} \times \frac{6}{1} = \frac{12}{3} = 4 \: cars \: per \: hour[/tex]

multiply again

[tex]4 \times 4 = 16[/tex]

Answer:

12

Step-by-step explanation:

The value of x is -(5 + 3√2).

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

7- 3√2-x=12

Now solving

7- 3√2-x=12

Subtract 7 from both side

7- 3√2-x - 7 =12 - 7

- 3√2-x = 5

Now, add 3√2 both side

-3√2 -x + 3√2 = 5 + 3√2

-x= 5 + 3√2

x= -(5 + 3√2)

Hence, the value x is -(5 + 3√2).

0.5+0.75+0.3=1.55

Answer:

Step-by-step explanation:

Let's assume that the length of a side of Allison's room as x

So, Lindsey's room = x + 3

If Lindsey's room needs 225 sq. feet of carpeting, then   x + 3 = [tex]\sqrt{225}[/tex]

So, x + 3 = 15

Therefore, x = 15 - 3 = 12 ( So, Allison's room has a side of length 12)

Therefore, the carpeting needed = 12 × 12 = 12² = 144 sq. feet

Step-by-step explanation:

Answer:

x = 1/9(b)

Step-by-step explanation:

Step 1: Subtract 6x from both sides.

Step 2: Subtract b from both sides.

Step 3: Divide both sides by -9.

Therefore, [tex]x = \frac{1}{9}b[/tex].

Answer:

A) You would use the two points that are closest to the graphed line

(2,7) and (8,13)

B) Slope = change in Y over the change in X:

Slope = (13-7) / (8-2) = 6/6 = 1

Slope = 1

c) Point slope is written as y -y1 = m(x-x1) where m is the slope y1 is the first Y value and x1 is the first x value.

Equation is: y-7 = x-2

d) To rewrite y -7 = x-2 in slope intercept form, you need to isolate y.

To isolate Y add 7 to both sides:

y = x +5

Step-by-step explanation:

The equation of line which passes through point (-7,-2) and having slope 3 is y = 3x + 10.

What is Algebraic expression ?

Algebraic expressions are numbers expressed using letters or alphabets without specifying their values. Algebra taught us how to express unknown values using letters such as x, y, and z. There can also be a single value that is placed before and multiplied by a variable in an algebraic expression in addition to these letters, which are called variables.

Here, it is given that line passes though point (-3,1) and having slope of 3.

Now, Let us find the equation of the line using point-slope equation of line :

(y-y₁) = m(x-x₁)

Substituting all the values in above equation to get the equation of line :

(y-1) = 3(x-(-3))

y -1 = 3x + 9

y = 3x + 9 + 1

y = 3x + 10

Therefore, the equation of line which passes through point (-7,-2) and having slope 3 is y = 3x + 10.
