Answer:
120 peas did Julia have to start with
Step-by-step explanation:
As per the statement: The ratio of Julia’s peas to Vlada’s peas was 3:2
Let the number be x;
Then;
Julia have number of peas to start with= 3x and Vlada's have number of peas start with = 2x
Also, it given that Julia gave 15 peas to Vlada, she still had 10 more peas than Vlada.
⇒ 3x - 15 = 2x + 10 + 15
3x -15 = 2x + 25
Add 15 both sides we get;
3x = 2x + 40
Subtract 2x from both sides we get;
x = 40
Number of peas Julia have = 3x = 3(40) = 120
and
Number of peas Vlada have = 2x = 2(40) = 80
Therefore, Julia have to start with 120 peas
Answer:
8 ejercicios
Step-by-step explanation:
De acuerdo a la información dada, puedes plantear las siguientes ecuaciones:
x+y= 45 (1)
7x-1y= 19 (2)
x= ejercicios que resolvió bien
y= ejercicios que resolvió mal
Primero, puedes despejar x en (1):
x= 45-y (3)
Segundo, debes reemplazar (3) en (2):
7(45-y)-1y=19
315-7y-1y= 19
315-8y= 19
315-19= 8y
296= 8y
y= 296/8
y= 37
Tercero, debes reemplazar el valor de y en (3) para encontrar x:
x= 45-37
x= 8

Answer:
Hello!
After reading your question I have calculated the correct answer to be:
47.22
Step-by-step explanation:
The way I solved this equation was I first split the equation into two parts.
I took the two whole numbers, being "34" and "12", and made their own equation:
"34+12=?"
And then I took the two partial numbers "0.98" and "0.24" and made their own equation:
"0.98+0.24=?"
I then solved both equations:
"34+12= 46"
"0.98+0.24= 1.22"
And added those two solutions together to come up with the final solution:
"46+1.22= 47.22"
Hope this helped!
