How is this grade 10? it's basic arithmetic. You need to learn this on your own if you have any hopes of graduating.

il do number 2

The Mackenzie river is 1183 km longer than the St. Lawrence. The sum of their lengths is 7299 km. How long is each river?


7299 Minus 1183 = 6116
6116 Divided by 2 = 3058

So the St. Lawrence is 3058 Kilometres Long (3048)
And the
Mackenzie is 4241 Kilometres Long (3048+1183)

3) The length of a rectangle is 5m more than its width. Its perimeter is 90 m. What are its dimensions?
the dimensions of the rectangle are 48x43
4) The number of frost-free days per year in Quebec City is 18 less than the number in Halifax. The total number in both cities is 292. How many frost-free days are there per year in Halifax?
k i think it is 194
5) The maximum life span of a brown bear is 10 times the maximum life span of a mouse. The sum of their maximum life spans is 33 years. What is the maximum life span of a mouse?

im not too sure but here goes

292 : 2 = 146

so now they are even
146
146
i add 9 to one and Sustract 9 to the other

so 146+9= 155 (Quebec City)
and 146-9= 137 (Halifax)

155-137=18 ^^

1) The sum of 2 numbers is 46. One number is 12 more than the other. What are the numbers?

The sum is that like Plus? or is it something diffrent lawlz

well here goes

46:2=23
12:2=6

23+6 =29
23-6=17

17+29=46,
and 29-17=12

I'd kill to have maths that easy, but grade 10, what age is that?
Like 12-14 or what?

[StealMySoda]

It's year 11. 15-16 years old.

[bryanvan]

Lol I am in grade 13 i guess then and i got really complicated math but I dont get this lol, mabye if i think more about it i will but in first sight i dont xD

[heroo]

It's year 11. 15-16 years old.

WTF?

15-16 years old get this kind of maths?

[StealMySoda]

To be honest, it's much easier to use algebra.

M=Maximum Life of Mouse, B=Maximum Life of Bear

M=x
B=10x

M+B=11x
33=11x
x=3

M=3

[DonBebek]

OMG where are u from
You call this 10th grade math
Unbelievable
I really suck at math and I'm also 16 yrs old and our math is like 10 times harder
If this is what I would be doing in some countries the I wanna move:D:D

[lmpulse]

wtf:O this is 10th grade math? im in 8th grade now, and we are doing exercises like this

[Doron]

what the ****?

why don't they make those things easy like 1+2??

**** maths. just makes us do + and -, then I'm happy...

they make stuff so hard these days, and I don't even need all that shizzle... like I would suddenly stand in a supermarket going like: hmmm.. a swiss chocolate bar is 20 cents more expensive then a bag of crisps.. together they are €1.40...

now how much do they both cost??

there are a brazillian options, yet, only 1 answer is good...

so, what the ****?
