Answer:
v = 15/7, or 2.14
Step-by-step explanation:
Find a common denominator, or multiply both denominators by each other, and well as the numerator.
v/5 = 3/7 can be written as 7v/35 = 15/35
multiplying both sides with 35, we are left with 7v = 15
v = 15/7, or 2.14
. The answer is 21.
Step-by-step explanation:
A dilation means that a shape is expanded or shrunk by a scale factor. The scale factor is 4, so all the points are multiplied by 4 to reflect this expansion.
A reflection over the y-axis means that the y-values in the points change their sign from positive to negative, and vice versa.
Therefore, the points will become the following:
A''(12,-12), B''(-4, -12), C''(-16,-4), D''(0, -4)
This new shape will be similar to the original shape, since it shares the same shape, but not the same size.
The answer is A.
Answer:
I'm having a hard time with this, I keep confusing myself but hopefully this example will help at least to get an idea:
"12 cm
Explanation:
We're pouring 12 litres of water into a container that is 40cm long and 25cm wide. Let's see how big the bottom of the container is:
40cm×25cm=1000cm2
1 litre of water fills 1000cm3, and so it would rise 1 cm (we divide the volume of the water by the surface area to arrive at the height):
1000cm31000cm2=1cm
12 litres of water can then be seen to rise 12 cm:
12×1000cm31000cm2=12cm"
1/2x + 1/3y = 3
Well, because every answer choice isn't in fraction form, simply multiply EVERYTHING by 6 :)
6(1/2x + 1/3y = 3)
Simplify.
3x + 2y = 18
So, our LAST answer choice is correct.
~Hope I helped!~
