Hello!
You have to find what a and b are
3a + 4a = 14
b + 6b = 21
Lets do a first
3a + 4a = 14
Combine like terms
7a = 14
Divide both sides by 7
a = 2
Now lets do b
b + 6b = 21
Combine like terms
7b = 21
Divide both sides by 7
b = 3
Put a and b into the third equation
7( 2 + 3) =
Do what is in parenthesis first
7(5) =
Multiply
35
The answer is 35
Hope this helps!
18=1,2,3,9,18
37=1,37
48=1,2,3,16,24,12,4,6,8,48
Prime no. is a number that is divisible only by itself and 1
So, here 37 is a prime no.
18 and 48 are composite no.s
So you've got a cartesian plane, right? There are two coordinates here. Plot the first one ((3.4)) first. the '3' is on the x axis and the '4' is on the y axis. Go 3 across until you get to 3. and then go 4 up. Put a dot there.
Next, also plot the second one. To do this, go to 3 on the x axis, and then go down until you get to -7 on the y axis. Plot your point with a dot. Then, join the dots up, and hopefully, it'll be a linear relationship!
