Answer:
Once.
Step-by-step explanation:
To find when they chirp together, we must find the LCM of the two numbers. The LCM, or least common multiple of 13 and 5 is 65. Therefore, after 65 minutes is the first time they chirp together. Then we can multiply 65 by 2 to see if they chirp a second time. 65x2 is 130, but 8AM-10AM is only 120 minutes, therefore they do not chirp together more than 1 time.
I’m not exactly sure what the question is asking, but assuming that the equation is r=10b^2, then the answer would be r=40.
Answer:
3x+3y and distributive property
Step-by-step explanation:
It is given that
Gretchen buys three bags of apples = 3X
Hayley buys three bunches of bananas = 3Y
As it is also mentioned that it first it is multiplied and then it is added
So, the expression for determining the total number of fruit pieces is
3X + 3Y
And, this expression denotes the distributive property in which we multiplied the each variable and then added it
Answer:
A roll of ribbon holds 6.75 meters. A craft club buys 21 rolls.
How many meters of ribbon did the club buy?
What is the total cost if the ribbon sells for $2 per meter?
Step-by-step explanation:
(x-3)^2+(y-2)^2=25
plug in those values for x,y to see if they satisfy the equation (=25)
