Answer:
2/4 and 3/4
Step-by-step explanation:
To make both fractions have the same denominator, multiply 1/2 by 2. 1/2 times 2 equals 2/4
It's 60 m because 2 cm is 20 mm, and if each mm is 3 m then 20*3 is 60
Let’s call the number of gallons of 30% solution “x”. If we mix together 40 gallons and x gallons of solution, we’re going to come out with a total of 40 + x gallons of that 20% solution. Mathematically, this is
40(12%) + x(30%) = (40 + x)(20%)
With the percents as decimals:
40(0.12) + x(0.3) = (40 + x)(0.2)
Simplifying, we have:
4.8 + 0.3x = 8 + 0.2x
Collecting the x terms on one side and the constants on the other:
0.1x = 3.2
And multiplying both sides by 10 to find x:
x = 32
So, you’ll need 32 gallons of 30% solution to yield 40 + 32 = 72 gallons of 20% solution.
4 - (-13) = 17

Answer:
(-6, 2) and (-7, -1) and (0, 0)
-------------------------------------------------
Explanation:
You reflected the triangle. You needed to translate the triangle.
y + 6 is to move up 6 units along the y-axis.
x - 5 is to move left 5 units along the x-axis.
Another thing, the question doesn't state was transformation to use so we are going to assume we are translating.
