Answer:
x=3 e y=4
Step-by-step explanation:
x/2=6/y=27/18
...
x/2=27/18
18.x=2.(27)
18x=54
x=54/18
x= 3
...
6/y=27/18
27y=6.(18)
27y=108
y=108/27
y=4
I think the answer is b 0.2(20)
Answer:
−28r−28
Step-by-step explanation:
−4(7r+7)
=(−4)(7r+7)
=(−4)(7r)+(−4)(7)
Answer:
For the first blank box, it would be 2, and for the second blank box, 40
Step-by-step explanation:
As we are told, we need 3 sticks of butter for every 24 cookies. We can make this simple by figuring out how many cookies we can make with one stick of butter.
To do this is easy: 24 divded by 3 = 8
So 8 cookies per stick of butter
16 cookies would be 2 sticks of butter (as 8 x 2 is 16, and there's 8 cookies per butter stick)
and with 5 sticks of butter, we do (5 x 8 ) which equals 40
Hope this helped !
The area of a triangle is determined by the formula: Base x Height * 1/2
You'll need to assign a base to the triangle. Based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). The distance between any two numbers is found by just subtracting them. Here, you should subtract the x values to find the distance of this side.
2 - (-2) = 4.
So the distance (aka the length of the base) is 4. The height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). We should subtract the y values this time to find the height/distance.
4 - 1 = 3
So the height is 3.
Base = 4
Height = 3
