Answer:
Option 1.
Step-by-step explanation:
The given equation is

To solve the given equation for x, first we need to use distributive property.
Using Distributive property we get

Now we need to add -2(-4)+4 on left side and 3(1)+1 on right side.
It is given that Maricella begins by adding –4 + 4 on the left side of the equation and 1 + 1 on the right side of the equation.
She was incorrect because the multiplication that takes place while distributing comes before addition and subtraction in order of operations.
Therefore, the correct option is 1.
You'd likely find this problem easier if you'd write these two numbers on separate lines, one above the other:

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!
The answer is 93 It’s 1209 divided by 13 not 13 divide by 1209 ;) hope this helps ! Because when we’re dividing the number get smaller and when we multiplying the number gets bigger , have a nice day !
