let x represent blueberry pie and y blackberry pie, then
x + 2y = 53 → (1)
10x + 3y = 224 → (2)
Multiplying (1) by - 10 and adding to (2) will eliminate x
- 10x - 20y = - 530 → (3)
Add (2) and (3) term by term to eliminate x
0 - 17y = - 306
- 17y = - 306 ( divide both sides by - 17 )
y = 18
Substitute y = 18 into either of the 2 equations and solve for x
Substituting into (1)
x + 2(18) = 53
x + 36 = 53 ( subtract 36 from both sides )
x = 17
Then
the cost of 1 blueberry pie is $17 and 1 blackberry pie is $18

The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
(11)
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, 2) and (x₂, y₂ ) = (0, 3)
m = [tex]\frac{3-2}{0-4}[/tex] = - [tex]\frac{1}{4}[/tex]
The line crosses the y- axis at (0, 3 ) ⇒ b = 3
y = - [tex]\frac{1}{4}[/tex] x + 3 ← equation of line
(12)
(x₁, y₁ ) = (- 3, 1) and (x₂, y₂ ) = (4, 2)
m = [tex]\frac{2-1}{4+3}[/tex] = [tex]\frac{1}{7}[/tex] , then
y = [tex]\frac{1}{7}[/tex] x + b ← is the partial equation
To find b substitute either of the 2 points into the partial equation
Using (3, 1 ), then
1 = [tex]\frac{3}{7}[/tex] + b ⇒ b = 1 - [tex]\frac{3}{7}[/tex] = [tex]\frac{4}{7}[/tex]
y = [tex]\frac{1}{7}[/tex] x + [tex]\frac{4}{7}[/tex] ← equation of line

6/7 times 3/4 = x
IN SIMPLEST FORM
Answer:
I believe 6/7 times 3/4 in the simplest form is 9/14 because you aren't able to put anything in both of those numbers
Step-by-step explanation:
The value of x in the equation (6/7) × (3/4) = x is 9/14.
To find the value of x in the equation (6/7) × (3/4) = x.
We can simply multiply the two fractions together.
Multiplying the numerators and denominators gives us:
(6 × 3) / (7 × 4)
= 18/28
The fraction 18/28 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2.
(18/2) / (28/2)
= 9/14

A TV that usually sells for $185.63 is on sale for 25% off. If sales tax on the TV is 5%, what is the price of the TV, including tax?
Answer: A TV that usually sells for $185.63 is on sale for 25% off. If sales tax on the TV is 5%, what is the price of the TV, including tax?
178.18 x 0.25 = 44.55
178.18 - 44.55 = 133.63 = sales price
133.63 x 0.05 = 6.68
133.63 + 6.68 = 140.31 = total price

27 + 9x = 12x - 6
(Provide steps)
Answer:
Let's solve your equation step-by-step.
27+9x=12x−6
Step 1: Simplify both sides of the equation.
27+9x=12x−6
27+9x=12x+−6
9x+27=12x−6
Step 2: Subtract 12x from both sides.
9x+27−12x=12x−6−12x
−3x+27=−6
Step 3: Subtract 27 from both sides.
−3x+27−27=−6−27
−3x=−33
Step 4: Divide both sides by -3.

PLZ SHOW HOW YOU SLOVED IT! THX <3
Answer:
$1039.74 and $6039.74
Step-by-step explanation:
Ok so if this is growing exponentially and is giving 6.5% per year then you would do (5000*0.065) + 5000 which is 5325 then you would do (for year 2). (5325*0.065) + 5325 which is 5671.125. And lastly, you would do (5671.125*0.065) + 5671.125 which is 6039.74 (rounded answer).
