1/2 = 0.5
3/5 = 0.6
The answer: 0.46, 0.5 (1/2), 0.6 (3/5), 0.6001.
Short answer: C
Remark
Since b is all by itself in equation 2, Substitute it into equation 1.
2a + 3b = 5
b = a - 5 Put this result in equation 1. Be sure and use brackets.
2a + 3(a - 5) = 5 Remove the brackets.
2a + 3a - 15 = 5 Notice the -5 inside the brackets becomes - 15
Combine like terms on the left.
5a - 15 = 5 Add 15 to both sides
5a = 5 + 15
5a = 20 Divide by 5
a = 20/5
a = 4
So far, c is the only possible answer.
b = a - 5
b = 4 - 5
b = - 1
Answer:10
Step-by-step explanation:
H(3)=3^2+1=10
Answer:
so you add then multiply then subtract
Step-by-step explanation:
His displacement ... the distance between his start point and
his end point ... was 10 miles. But we don't know what route
he followed on the way, so we don't know how much distance
he actually walked or drove. It couldn't be less than 10 miles,
but it could be any distance more than 10 miles.
