Answer:
Step-by-step explanation:
5y and 45 are supplementary. They add to 180 degrees.
5y + 45 = 180 Subtract 45 from both sides.
<u> -45 -45</u>
5y = 135 Divide by 5
/5 /5
y = 27
2x+ 1 and 45 are vertically opposite which means they are equal.
2x+1 = 45 Subtract 1 from both sides
2x + 1 -1 = 45-1
2x = 44 Divide by 2
/2 /2
x = 22

Answer:
3. 273
4. 168
5. 189.25
Step-by-step explanation:
3. Triangle= .5 x 17 x 6 = 21
Rectangle= 18 x 14 = 252
252 + 21 = 273
4. Big rectangle (shaded)= 11 x18= 198
Small rectangle (right)= 5x4=20
Smaller rectangle (left)= 2x5=10
BR - (SR+SMR)
198-30=168
5. radius=5
Area of the circle= 25(pi)
Semi-circle= 39.25(not exact)
Rectangle= 10 x15=150
Rectangle + Semi-circle
150+39.25=189.25
It would cost $17.15 dollars. You need to divide 4500 by 42 and round up to the nearest hundredths so it would be 17 dollars and 15 cents
Step-by-step explanation:
Số gà mái: 24 : 6 x 5 = 20 (con)
Số gà cả đà: 24 + 20 = 44 (con)
=> Tỉ số giữa gà mái và số gà của đàn: 20/44 = 5/11
