Jim's piano lessons are 30 minutes
longer than Suzanne's clarinet
lessons, Suzanne's clarinet lessons
are one-third the length of Pedro's
guitar lessons. If Pedro's guitar
lessons are 60 minutes long, how long
are Jim and Suzanne's lessons?
Answer:
Suzanne's lessons are 20 minutes long.
Jim's lessons are 50 minutes long.
Step-by-step explanation:
Jim's lessons = 30min longer than Suzanne's lessons
Suzanne's lessons = 1/3 of Pedro's lessons
Pedro's lessons = 60min
First, you need to find Suzanne's lesson time because her lessons are linked to Pedro's. Since you know Pedro's lesson is 60 minutes long and Suzanne's are a third of that you do: 60/3. Which is 20. So you know Suzanne's lessons are 20minutes long.
Next, since you know Suzanne's lessons are 20minutes long and Jims are 30mins longer than Suzanne's you do: 20+30. Which equals 50minutes. So, Jim's lessons are 50minutes long.

The product of the Expression is 3/ (a-2).
What is Expression?In mathematics, an expression is a phrase that has at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression's structure is as follows:
(Number/variable, Math Operator, Number/variable) is an expression.
We have,
(2a - 7)/ a x (3a²)/ (2a² -11a + 14)
Now, simplifying the expression as
(2a - 7)/ a x (3a²)/ (2a² -11a + 14)
= (2a - 7)/ a x (3a²)/ (2a² -7a - 4a + 14)
= (2a - 7)/ a x (3a²)/ a (2a -7) -2 (2a- 7)
= (2a - 7)/ a x (3a²)/ (a- 2)(2a-7)
= 3a² / a(a-2)
= 3/ (a-2)
Thus, the product is 3/ (a-2).

y + 2 = 1/2 (x - 4)
Answer:
y = ½x - 4
Step-by-step explanation:
Given the linear equation in point-slope form, y + 2 = ½(x - 4):
To transform the equation into its slope-intercept form, y = mx + b:
y + 2 = ½(x - 4)
Distribute ½ into the parenthesis:
y + 2 = ½x - 2
Subtract 2 from both sides:
y + 2 - 2 = ½x - 2 - 2
y = ½x - 4 ← This is the slope-intercept form.

What is (5,3) and (6,7) in point slope form
Answer:
4
Step-by-step explanation:
( x1, y1 ) = ( 5, 3 )
Here,
x1 = 5
y1 = 3
( x2, y2 ) = ( 6, 7 )
Here,
x2 = 6
y2 = 7
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope = ( 7 - 3 ) / ( 6 - 5 )
= 4 / 1
Slope = 4
Answer:
(y−3)=4(x−5)
Step-by-step explanation:
Point slope form is defined by the formula [tex]y-y_{1}=m(x-x_{1})[/tex]
First, you find the slope using the slope equation [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]. (7−3)/(6−5)=4. Then you plug it back into the point slope form equation, and also plug in the points from y1 and x1.
This is also y=4x−17 in slope-intercept form or −4x+1y=−17 in standard form.
4(a+x)-b=16 solve for the variable x (pls help me)
Answer:
x = [tex]\frac{16+b-4a}{4}[/tex]
Step-by-step explanation:
4(a + x) - b = 16 ( add b to both sides )
4(a + x) = 16 + b ← distribute parenthesis on left side
4a + 4x = 16 + b ( subtract 4a from both sides )
4x = 16 + b - 4a ( divide both sides by 4 )
x = [tex]\frac{16+b-4a}{4}[/tex]

could someone help me with this question including a full explanation? thank you have a great day.
Step-by-step explanation:
just think about the basic formulas for area and perimeter of rectangles, and what pieces of information we already have directly.
area = length × width
perimeter = 2×length + 2×width = 136 m
=> length + width = 68 m
then we know
length = 2×width + 8
this we use as substitute in the simplified perimeter equation :
2×width + 8 + width = 68
3×width + 8 = 68
3×width = 60
width = 20 m
and therefore
length = 2×width + 8 = 2×20 + 8 = 40+8 = 48 m
and now we can calculate the area :
area = length×width = 48×20 = 960 m²
please consider that for a length or distance we use m (or other length units), for and area then m². for a volume then m³. as a basic unit for an area is a square. and for a volume a cube.
