Let x be the number of 52 cent stamps that Sally has and let y be the number of 34 cent stamps that she has.
Then,
52x + 34y = 1150 --- (1)
Also, she has six more 34 cent stamps than 52 cent stamps.
Therefore, y = x + 6
(1) becomes
52x + 34(x + 6) = 1150
52x + 34x + 204 = 1150
86x + 204 = 1150
86x = 1150 - 204
86x = 946
x = 11
and y = 11 + 6 = 17
Hence, Sally has eleven 52 cent stamps and seventeen 34 cent stamps.
Answer:
Yes , the number should be even and divisible by 5 and then it can be divisible by 10 as well
Answer:
x+6=y and 3x=12
Step-by-step explanation:
Let x be the distance traveled by Bryan and let y be the distance traveled by Sam then the first equation would be:
x+6=y (x plus 6 is equal to y, Bryan's distance plus 6 is equal to Sam's distance) and the second one is:
3x=12 (3 times x is 12, 3 times the distance travelled by Bryan is 12)
So our statements/equations are:
x+6=y and
3x=12 (we dont write this as x=4 as it asks us to give the statements we got from the information given, we only start simplifying once it tells us to solve)
Do -4 times 3.2 and then do the same thing plzzz help me with a question now plzzz I all give you 100 points
Answer:
Step-by-step explanation:
Subtraction is not commutative. For example, 4 − 7 does not have the same difference as 7 − 4. The − sign here means subtraction.
However, recall that 4 − 7 can be rewritten as 4 + (−7), since subtracting a number is the same as adding its opposite. Applying the commutative property for addition here, you can say that 4 + (−7) is the same as (−7) + 4. Notice how this expression is very different than 7 – 4.
