5d=17.1
d=17.1÷5
d=3.42
Hopefully this is enough work shown :)
The equations would be:
x=18+3y
x+y=54
(substitute x in the second equation with 18+3y)
18+3y+y=54
(combine like terms and solve for y)
y=9
(plug y into the second equation to find x)
x+9=54
x=45
Answer:
Nina's Garden has an area of 1.3 meters
Step-by-step explanation:
All we have to do is multiply.

Answer: 5894.2
Step-by-step explanation:
You'll want to follow PEMDAS to simplify this expression.
1.) P - Parentheses
2.) E - Exponents
3.) M - Multiplication
4.) D - Division
5.) A - Addition
6.) S - Subtraction
We'll start with what's inside the parentheses:
(2.4 × 1018) + (3.4 × 1015)
(2,443.2) + (3,451)
Now all you have to do is add the values together to get your answer!
2,443.2 + 3,451
5894.2
23.8
you round the 4 down so 8 stays as 8, if it was 23.85 then it would become 23.9
