Answer:
>
Step-by-step explanation:
First we get the same denominator by finding a common multiple.
20 is the lowest common multiple so let's use that.
9/10 will have to change so that the denominator is 20.
From 10 to 20 we have multiplemultiplied it by 2 so we will do the same to the numerator.
9 × 2 = 18.
The fraction is now 18/20.
Now 3/4 – we will get to 20 by multiplying by 5.
3 × 5 = 15
Now we can compare
18/20 and 15/20
9/10 and 3/4
I think the lowest common multiple of 12, 40, and 45, 40, and 12 would be 360
You plug the (2x-4) in for y to look like 6r-3(2x-4)=12. then when you solve and subtract the 12 from the other 12 you’re left with 6r-6x=0. divide the 6 out and the answer is r=x all real numbers.
Answer:
D. K'(-4, 8)
Step-by-step explanation:
Given the coordinate (x,y), if this coordinate is dilated by a factor of k, the resulting coordinate will be expressed as (kx, ky). Note that each coordinate is multiplied by the scale factor.
Similarly considering the coordinate K(-1, 2) according to the question. If this coordinate is dilated by a factor of 4, the resulting coordinate is expressed as;
= K'(4(-1), 4(2))
= K' (-4, 8)
Hence the coordinate of K' will be at (-4, 8)
Answer:
D) (70 + 65) + 80
Step-by-step explanation:
70 + (65 + 80) = 215
A) (70 + 65) × (70 + 80) = 135 × 150 = 20,250
B) (70 × 65) + (70 × 80) = 4,550 + 5,600 = 10,150
C) (70 × 65) + 80 = 4,550 + 80 = 5,030
D) (70 + 65) + 80 = 135 + 80 = 215
E) None of the above
