Answer:

G) 16.6

Step-by-step explanation:

We can use the pythagoriam theroem to solve the problem

a^{2} + b^{2} = c^{2}

a^{2} + 7^{2} = 18^{2}

a^{2} + 49 = 324

a^{2} = 275

a = 16.6

What value of a makes the solution to the equation 5x-10=3x+a equal to 12
Illusion [34]

Answer:

a=-1.2

Step-by-step explanation:

5x-10=3x+a=12

let's first find x:

5x-10=12

add 10 to both sides:

5x=22

divide both sides by 5:

x=4.4

now that we know what x is, we can plug it back into the equation to find a:

3*4.4+a=12

first, simplify both sides:

13.2+a=12

then, subtract 13.2 from both sides:

and our answer is: a=-1.2

If a recipe calls for 0.800 kg of flour , about how many ounces of flour does it need? (1lb=16 oz, 1 lb = 0.454 kg )
stiks02 [169]
For this case we must take into account the following conversions of units:
 1lb = 16 oz
 1 lb = 0.454 kg
 Applying the conversion of units we have:
 (0.800) * (1 / 0.454) * (16/1) = 28.1938326
 Rounding off we have:
 28.2 oz
 Answer:
 
it needs 28.2 oz of flour
