We have, /x+5.3/ = 2.1;
Then, x + 5.3 = 2.1 or x + 5.3 = -2.1;
x = 2.1 - 5.3; x = -3.2;
x = -2.1-5.3; x = -7.4;
The correct answer is c.
H has to be a number so that when you divide it by nine it will equal nine.
Reversing this, it would look like this.
9*9=h
h=81
Answer:
Step-by-step explanation:
8 weeks

Her speed will be affected by the speed of the river therefore her speed upstream will be 2.6-0.4 mph and her speed downstream will be 2.6+0.4mph
Therefore upstream it will take 4.4/2.2=2 hours
And downstream it will take 4.4/3=1.47 hours (3sf)
