Step-by-step explanation:
If 3ml of water = 1 part milk
12ml of water = x
3x=12
3x/3=12/3
Cancelling out by 3
x=4
Therefore she will need 4 part milk to make the recipe.
It’s D , -16.2
you replace X with -142 and get -0.2 (142 + 223)
Answer:
9 - b = ? 9 - 8 = 1 So, your answer is 1.
Step-by-step explanation:
Answer:
25
Step-by-step explanation:
You need to reverse the operations given that 60 is equal to (2x+10)
so first you would subtract 10 from 60 that would equal 50. that divide by two to get 25.

Answer: A) 4^9</h3>
The rule you use is
a^b * a^c = a^(b+c)
The base stays the same at 'a' the whole time. We add the exponents. If the bases were different on the left hand side, then we cannot use this rule.
In this case, a = 4, b = 6, c = 3.
4^6 * 4^3 = 4^(6+3) = 4^9
