Answer:
2120 mm
Step-by-step explanation:
→ Convert 2.12 metres into centimetres
2.12 × 100 = 212 cm
→ Multiply by 10 to get into mm
212 × 10 = 2120 mm
Answer:
A. 7.5 cm
Step-by-step explanation:
3/4 = (x + 3)/(2x + 1)
3(2x + 1) = 4(x + 3)
6x + 3 = 4x + 12
2x = 9
x = 4.5
BC = x + 3
= 4.5 + 3
= 7.5 cm
Answer:
the square root of 121 is 11
180- 61= 119 degrees
A line is 180 degrees. You’ve been given part of the line, so that plus the other part has to equal 180. b and c are equal
The parts of the sum are 55 and 80.
Step-by-step explanation:
Let,
'x' be the smaller part and
'y' be the greater part of the number.
The sum is x+y = 135. --------(1)
The greater part y = x+25. ---------(2)
Substitute (2) in (1),
⇒ x+(x+25) = 135
⇒ 2x+25 = 135
⇒ 2x = 110
⇒ x= 110/2
x = 55
The smaller part is 55.
Substitute x=55 in (2)
y = 55+25 = 80
The greater part is 80.
