Answer:
A su mamá
= 2937 pesos
A su hermano
= 1566.4 pesos
El resto para ella
= 3328.6 pesos
Step-by-step explanation:
El número total de pesos que cada uno consiguió se calcula como:
Su madre
= 3/8 del total
= 3/8 × 7832
= 2937 pesos
Su hermano
= 1/5 del total
= 1/5 × 7832
= 1566.4 pesos
Sí misma
= El resto
= 7832 - (2937 + 1566,4)
= 7832 - 4503.4
= 3328.6 pesos
Answer:
x = .87, or when approximated to a fraction, 27/31
y = -3.67, or when approximated to a fraction, -1287/350
Step-by-step explanation:
Lets start by rewriting out our equations
2x + 7y = -24
18x + y = 12
Lets solve for a y value; the second equation is easiest, as the y value has no coefficient (the number that is multiplied times a variable). To do this, lets move the 18x to the other side. Now our two equations look like:
2x + 7y = -24
y = -18x + 12
Next, lets plus the second equation into the first equation in regards to y.
2x + 7(-18x + 12) = -24
Now, lets solve!
2x -126x + 84 = -24
Then, combine your terms!
-124x = -108
Divide by (-124)!
x = -108/-124
x = 27/31
Now that we know x, lets plug this back in to the first equation to find y!
2(27/31) + 7y = -24
1.74 + 7y = -24
7y = -25.74
y = -3.67, or when approximated to a fraction, -1287/350
