Zoee: Here's a case where parentheses are badly needed to clarify this post. I am unsure of whether you mean 4*sqrt(9)/2x, or 4*sqrt(19/2)/ x or something else.
All I can do here is work backwards from the given possible answer "sqrt(9x)". That could be simplified to "sqrt(9)*sqrt(x)", which equals 3*sqrt(x). Not very helpful.
So, Zoee, at this point I recommend that you share an image of the original problem. Could you take and share a screen shot? Only with the original problem in mind could I help you meaningfully as you try to express the problem and its possible solutions.
Answer:
25
Step-by-step explanation:
see picture for work!
Answer:
<u>Subtract 1 from both sides</u>
<u>Divide both sides by 3</u>
To solve these, plug in the x values into the equations and solve for y.
For the first box, you would substitute x for -2:
y=2(-2)+5
y=-4+5
y=1
Just do the same thing for the rest of the boxes and you'll be good. In the last two boxes in the second problem, you can choose what you want x to be. Hope this helps.
Answer:
d) 5 lollipops each and 3 left over
Step-by-step explanation:
To find out how many each of them get, you need to find the total amount of lollipops to be shared equally.
Total No. of lollipops = 3 + 5 + 7 + 4 + 9
= 28
No. of lollipops each of them get = 28 ÷ 5
= 5 R3
(To find the remainder of something, you have to know how much is the quotient (which is 5 in this case), multiply it by the divisor (which is also 5 in this case) then minus that number from the total (which is 28 in this case) )
Additional working:
5 × 5 = 25
28 - 25 = 3 (remainder)
