Answer:
y=10
Step-by-step explanation:
2y+3+9y-7+7y+4=180
18y=180
y=10
Answer:
-⅖
Step-by-step explanation:
We need to simplify the given equation and find out the value of a , as ,
=> 3(a-1)+31-11a = 4(2a+3)
=> 3a -3+31-11a = 8a + 12
=> -8a -28 = 8a + 12
=> 16a = -28-12
=> 16a = -40
=> a = -2/5
<h3>
• Hence the value of a is -⅖ .</h3>
I have this picture and I hope it helps. the equation should be kilogram divided by 1000 (I think). Hope this helps. God bless you! have a good day!
Answer:
The scale factor of the following dilation is, 0.5
Step-by-step explanation:
The rule of dilation with scale factor k is given by:

As per the statement:
Given the following dilation:
(10, 0) → (5, 0) .....[1]
We have to find the scale factor.
Using the above rule we have;

Now compare this with equation [1] we have;
(10k, 0) = (5, 0)
⇒10k = 5
After solving we get;

Therefore, the scale factor of the following dilation is, 0.5
