10 × 8 = 80 squared feet
(wall space)
5 × 3 = 15 squared feet
(area of the window)
80- 15 = 65 squared feet
(the amount of area she will be painting on)
Given equations : Equation A: 4y -3x =16 and
Equation B: -x-8y =3.
We are given a<em> point (-5,0.25) plugging it in first equation</em>
4(0.25) -3(-5) =16
1+15 =16.
16 =16 <em>: Satisfies first equation.</em>
Plugging (-5,0.25) it in second equation.
-(-5)-8(0.25) =3.
5 - 2 = 3.
3=3 <em>: Satisfies first equation.</em>
<h3>Therefore, they are the only values that make both equations true.</h3>
Answer:
x = -5
Step-by-step explanation:
6x + 10 = 4x
2x = -10
x = -5
5 1 and 8 only one side is negative
Answer:
619.5cm2
Step-by-step explanation:
Based on what you defined as the parallel sides been 26cm and 33cm and the height been 21cm.
Hence the are of trapezium is half sum of the parallel sides × height.
Expressed mathematically we have:
1/2( 26 +33) × 21 = 1/2 ( 59) × 21 = (59×21)/2= 619.5cm2
