Find the area of each parallelogram a equals base height 11 in 9 in​
Paul [167]

Answer:

Area of the parallelogram is 99 inch²

Step-by-step explanation:

We are given that,

Base of the parallelogram = 11 inches

Height of the parallelogram = 9 inches

Since, we know,

Area of a parallelogram = Base × Height

So, we get,

Area of the parallelogram = 11 × 9 = 99 inch²

Hence, the area of the parallelogram is 99 inch².

Solve the simultaneous equations<br> 2x+y=5<br> 5x+3y=12
Bezzdna [24]

Answer:

x=3 and y= -1

Step-by-step explanation:

Step 1: Solve2x+y=5 for y:

2x+y=5

2x+y+−2x=5+−2x(Add -2x to both sides)

y=−2x+5

Step 2: Substitute−2x+5foryin5x+3y=12:

5x+3y=12

5x+3(−2x+5)=12

−x+15=12(Simplify both sides of the equation)

−x+15+−15=12+−15(Add -15 to both sides)

(Divide both sides by -1)

x=3

Step 3: Substitute3forxiny=−2x+5:

y=−2x+5

y=(−2)(3)+5

y=−1(Simplify both sides of the equation)

Answer:

x=3 and y=−1
