Answer:
2 2/21
Step-by-step explanation:
11/2 ÷ 2 5/8
= 11/2 ÷ 21/8
= 11/2 × 8/21
= 88/42
= 44/21
= 2 2/21
Hence 11/2÷2 5/8 is 2 2/21
Answer:
5x+15y=85
Step-by-step explanation:
X and Y are the unknown variables, just add them to 5,(cars), and 15 (minibus)
Answer:
4n + 8 = -48
n = -14
Step-by-step explanation:
Using key words from the problem, you can set up an equation with the proper operations to solve for the variable. Product = multiplication, so the 'product of 4 and a number' = 4n. Increased = addition, so increased by 8 = 4n + 8. The word 'is' means equal to, so:
4n + 8 = -48
In order to solve for 'n', you use inverse (opposite) operations and whatever you do to one side of the equation, you do to the other:
Subtract 8: 4n + 8 - 8 = -48 - 8 or 4n = -56
Divide 4: 4n/4 = -56/4
Solve for 'n': n = -14
All you’re doing is subtracting $15.35 from $20.00. After you get the answer, add $1.25 as many times as possible before it exceeds the number you got from the first subtraction.
$20.00 - 15.35 = $4.65
$1.25 x 3 = $3.75
(Anything over $3.75 would require additional money, so you couldn’t buy any more chocolate bunnies than 3.)
You could buy 3 chocolate bunnies after purchasing 1 dozen tulips for $15.35 with the remaining $4.65 you have left.
I struggle with math myself, so I’d recommend working it out on your own instead of pasting online answers because it pays off in the end! <3
Answer:
It will give you the opposite sign.
Step-by-step explanation:
If you multiply two negatives you will end up with a positive and vice versa with positives. The same thing applies to dividing.
