Answer:
r is less than or equal to -28
Step-by-step explanation:
(-2r-9) +14 +3r ≤ 11-34
Combine like terms
1r+5 ≤ -23
Subtract 5 to isolate variable
1r ≤ -28
Divide to get r isolated
r ≤ -28
Answer:
-39
Step-by-step explanation:
you do-3 times 13 and you get -39. -39/-3 is 13
Answer:
the equation is
x - 4 = - 9
the number is
-5
Step-by-step explanation:
First, we don't know the number so we represent it with a variable like "x".
then difference simply means subtraction.
" is" simply means = ( equal to)
so the question says that difference of 4 and a number is 9 so we have x - 4 = -9
so now let's solve for x
we group liked terms and make x stand alone.
x = -9 + 4
( +4 because it crossed an equal sign)
x = - 5
we have
x = -5
so we can substitute the -5 into the equation to if its true
from the equation x - 4 = - 9
where we put -5 instead of x
-5 - 4 = - 9
Answer:
-3
Step-by-step explanation:
Distribute the -2 into (x-2.5) and it would be y + 8 = -2x + 5
Subtract 8 and it would be y = -2x - 3
Therefor your answer is -3
Answer: option B is the correct answer
Step-by-step explanation:
Candace's backyard has a flower garden that covers 40% of her backyard.
If the total area of her backyard is 450 square feet, it means that her garden covers 40% of 450 square feet.
To determine how many square feet is her flower garden, we will find the value of 40% of 450 square feet. It becomes
40/100 × 450= 0.4×460 = 180 square feet
