Answer:
No. of sweets Sue has = (18-x) -5
No. of sweets Tony has = (18+x)/2
Step-by-step explanation:
Sue has sweets = 18
Tony has sweets = 18
Sue give Tony sweets = x
Sweets left for Sue = 18 - x
Sweets for Tony = 18 + x
Sue eats 5 sweets = (18-x) -5
Tony eat half of his sweets = (18 +x)/2
No. of sweets Sue has = (18-x) -5
No. of sweets Tony has = (18+x)/2
10 and 4
4 - 2 = 2
10 + 2 = 12
Answer:
122.5
Step-by-step explanation:
Use the area formula for a trapezoid (attached below as an image):
A = area in sq cm
a = top base
b = bottom base
h = height
Correspond the correct values with the variables:
a = 14
b = 21
h = 7
A = 1/2 * (14 + 21) * 7
A = 1/2*(35)*7
A = 17.5 * 7
A = 122.5 sq cm
