Answer:
The river is 3.15 feet deep.
Step-by-step explanation:
First let's recognize what we need to find: the depth of the river
We know last year the river was 4.2 feet deep, but it dropped 25%. This means we also need to find how much it dropped. To find this, we need to know what 25% of 4.2 is. Write an equation for this.
y = 25% of 4.2
y = 0.25 • 4.2
y = 1.05
This means that the river dropped 1.05 feet. To know its depth now, we need to subtract 1.05 from 4.2. Write an equation for this.
d = 4.2 - 1.05
d = 3.15
The river is 3.15 feet deep.
Hope this helps!
Answer:
525
Step-by-step explanation:
Answer:
x = 18
Step-by-step explanation:
5/6x = 15
Multiply each side by 6/5 to isolate x
6/5 * 5/6 x = 15 *6/5
x = 15/5 *6
x =3*6
x = 18
It’s B, you go down 3 times from p and went over to the left 4 times and 3+4 =7
