Answer:
Step-by-step explanation:
Perimeter = 2*(length +width)
P = 2*( x+8 + y-1)
P = 2*(x + y + 7)
P =2x + 2y + 17
1/4(8-4p) + 2p = 12
Use distributive property by multiplying 1/4 by each term inside parentheses:
2 - p + 2p =12
Combine like terms:
2 + p = 12
Subtract 2 from both sides:
P = 10
Answer:
15-12+5.5+3-8
Step-by-step explanation:
15-12=3
3+5.5=8.5
8.5+3=11.5
11.5-8=3..5
Answer:
14
Lex read 7 but Lena had to have 7 books which yea
He needs to run with approximately 6429 for a distance of 9 km
<h3>How to determine the number of strides?</h3>
The given parameters are:
Length of stride = 1.4 m
Distance for marathon = 9 km
The number of strides needed is then calculated as:
Number of stride = Distance for marathon/Length of stride
Substitute the known values in the above equation
Number of stride = 9km/1.4m
Convert km to m
Number of stride = 9000m/1.4m
Evaluate the quotient
Number of stride = 6428.57143
Approximate the estimate
Number of stride = 6429
Hence, he needs to run with approximately 6429 for a distance of 9 km
