Answer:
60 and 38
Step-by-step explanation:
let the two numbers be X and Y
X + Y = 98-----------(1 )
X - Y = 22-----------(2)
using elimination method, subtracting equation (1) from equation (2)
X - X = 0
+Y -(-Y) = Y + Y = 2Y
98 -22 = 76
2Y = 76
dividing bothsides by 2
2Y/2 = 76/2
Y = 38
substitute Y = 38 into equation (1)
X + 38 = 98
X = 98-38 = 60
therefore, the two numbers are 60 and 38
Her fuel tank is not empty. She added 3/4 gallon of fuel and used 2/4 which still leaves 1/4 gallon left. If she had only put 1/2 a gallon, it would have been empty.
Answer:
0.9km
Step-by-step explanation:
Given that:
Sonya's resolution = walk 2.5 km daily
Total distance walked on Tuesday = 4 times around a running track
1 lap = 0.4 km
Hence, total distance by walking 4 times around track :
0.4km * 4 = 1.6km
Additional kilometers Sonya needs to walk:
2.5 - 1.6 = 0.9 km
Answer:
(x+6)
Step-by-step explanation:
because you have ( x+6) on bottom of the first equation and on the top on the second equation
Midpoint (m) = (x₁ + x₂)/2 , (y₁ + y₂)/2
= (3 - 11)/2, (-5 + 1)/2
= -8/2 , -4/2
= -4 , -2
distance (d) = √[(x₁ - x₂)² + (y₁ - y₂)²
=√ [(-4 - (-2))² + (-2 - 4)²
= √[(-2)² + (-6)²]
= √[4 + 36]
= √40
= 2√10
