Answer:
1) 18m²
2) 25cm²
Step-by-step explanation:
1)
- a = ½ × b × h
- a = ½ × 9 × 4
- a = ½ × 36
- a = 18m²
2)
- a = ½ × b × h
- a = ½ × 10 × 5
- a = 5 × 5
- a = 25 cm²
Convert yards to feet
1yard=3ft
times both sides by 7
7 yards=21ft
7yards 2ft, 6in is
21ft+2ft and 6in or
23ft and 6in
so from 23ft 6in to 30ft 9 in is how much?
30ft, 9in-23ft, 6in=
30ft-23ft, 9in-6in=
7ft, 3in
he was 7ft, 3in short
• y is vertically opposite to the one whose measure is 43º.
So,
y = 43º.
• x and y are supplementary angles:
x + y = 180º
x = 180º <span>– y
x = 180º </span><span>– 43º
x = 137</span><span>º.
</span><span>• z and x are vertically opposites.
So,
z = x
z = 137º<span> <</span></span>——<span><span>— this is the answer.</span>
I hope this helps. =)

Answer:

Step-by-step explanation:
multiply first equation by 4 and second by 3 respectively:

combine the equations:

divide both sides by -48:

substitute the value of y to the second equation

simplify multiplication:

cancel 12 from both sides:

divide both sides by 4

therefore our solution is
