Answer:
Question A is D and Question B is B
You can say
x+y=5
x=5-y
You know the value of x, put it into the next equation.
3(5-y)-7y=19
15-3y-7y=19
15-19 = 10y
-4=10y
-4/10=y
-2/5=y
Put y value back into either equation to find value of x.
x+y=5
x-2/5=5
x=5+2/5
x=27/5
Therefore, x,y = (27/5, -2/5)
Hope I helped :)
Answer: 176
Step-by-step explanation:
To evaluate the equation we have to remove the parentheses and add 15 + 17...
1/2 (11)(15 + 17) =
= 11 * 32 * 1/2
Now, we have to turn it into a fraction and multiply it...
= 
352 ÷ 2 = 176
I hope this helps!
S would be equal to 10. We’d multiply 45 by 2 to get the 90 then divide by 9 to isolate it
First would be Red Marbles Second would be Blue and last Yellow. (remember this is <em><u>not</u></em> exact)
I'm sure this is good! :D
