Answer:
<h2>30</h2>
Step-by-step explanation:
<h3>to understand the steps</h3><h3>you need to know about:</h3>
- system of linear equation
- word problems
- PEMDAS
first step
let's create the equation word problem
<h3>my mother's current age is four times the sum of the ages of my two sisters. After 5 years, my mother's age will be double the sum of the ages of my two sisters. What is the current age of my mother? (imaginary problem)</h3>
let's solve
let my mother's and sister's age be x and y respectively
according to the first condition,x=4y....(I)
according to the 2nd condition,x+5=2(y+5×2).....(ii)
so the system of linear equations is
x=4y
x+5=2(y+5×2)
gets from the second equation
x+5=2(y+10)
x+5=2y+20
4y+5=2y+20 (as x=4y)
2y=15
y=7.5
so the age of mother is
x=4.(7.5)
x=30
Answer:
11.33 cups
Step-by-step explanation:
240 grams of carbohydrates: x
40 x + 4 x + 26 x = 240
X = 240/70
X = 3 3/7 cups
332 grams of fats = y
0y + 13y + 70y = 332
Y = 332/83
Y = 4 cups
207 grams of proteins = z
5z + 21z + 27z = 207
Z = 207/53
Z = 3 48/53 cups
3 3/7 + 4 + 3 48/53 = 11.33 cups
