<em>A(a) = 24 cm²</em>
<em>A(b) = 40.04 cm² ≈ 40 cm²</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>area formula (rectangle)</em>
<em>A = l × w</em>
<em>A(a) = 8cm × 3cm = 24 cm</em>
<em>A(b) = 5.2cm × 7.7cm = 40.04 cm² ≈ 40 cm²</em>
<em>Good luck !</em>
Answer:
Step-by-step explanation:
y-4x=6
y=6+4x, using this value in 2y-3x=4 gives
2(6+4x)-3x=4
12+8x-3x=4
5x+12=4
5x=-8
x= -8/5= -1.6, making y=6+4x become
y=6+4(-1.6)
y= -0.4, so the solution is the point
(-1.6, -0.4)
Answer:
y = x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c )
Given
3y - 3x = 21 ( add 3x to both sides )
3y = 3x + 21 ( divide all terms by 3 )
y = x + 7 ← in slope- intercept form
---------------------------------------
Slope :
---------------------------------------
y = -5x + 2
Slope = -5
---------------------------------------
y - intercept :
---------------------------------------
At (0. 3), y-intercept = 3
---------------------------------------
Equation :
---------------------------------------
y = mx + b
y = -5x + 3
---------------------------------------
Answer : y = -5 + 3
---------------------------------------
As we could "drag" these together, we could then do it the easy way.
56
+56
+56
-------
168
------------------------
Or we could also do the following:
56
3:
6
3= 18.
Carry the one.
5
3 = 15+1 (which was carried). = 16
(16+8) =
168
