You minus 7 on both sides and you are left with y=2 because 7-9 = 2
Answer:
A 175/979 = M
Step-by-step explanation:
Si Matusalén vivió 979 años y Abraham vivió 175 esto quiere decir que abraham vivio menos años que Matusalén.
Por lo que la fracción va a tener que ser menor que 1 ya que al multiplicarla por la edad de Matusalén nos tiene que dar la de Abraham.
Tenemos que encontrar una fraccion que multiplicada por 979 nos de 175.
979 * X = 175
Tenemos que despejar la x y encontraremos el valor de la fraccion.
979 * X = 175
X = 175/979
Nos fijamos si se puede simplificar, no se puede asique este es el resultado final.

Answer:
2525
Step-by-step explanation:
1. Draw a block diagram to illustrate the different types of chocolate bars. (In this diagram, the creamy chocolate bars are shown as orange blocks, the milky chocolate bars as blue blocks and the white chocolate bars as red blocks.)
2. Since the number of creamy chocolate bars was 5 times the number of milky chocolate bars, we can replace one orange block (creamy) with 5 blue blocks (milky).
Since the number of white chocolate bars was 715 more than the number of milky chocolate bars, we replace one red block with one blue block + 715.
3. Looking at the block diagram, find the number of milky chocolate bars (blue block)
4250 – 715 = 3535
7 blue blocks = 3535
1 blue block = 3535 ÷ 7 = 505
The number of milky chocolate bars made was 505.
4. Calculate the number of creamy chocolate bars.
The number of creamy chocolate bars was 5 times the number of milky chocolate bars = 5 × 505 = 2525
Answer:
x = variable (a symbol, usually a letter, representing possible inputs)
4 = constant (numbers that stand alone and have a fixed value)
3 = coefficient (number multiplied by variable)
