Answer:
Step-by-step explanation:
Let the numbers be x and y
<u>Three times the first number minus two times the second number equals -7:</u>
<u>The second number equals one less than negative three times the first number:</u>
<u>Substitute y in the first equation and solve for x:</u>
- 3x - 2(-3x - 1) = -7
- 3x + 6x + 2 = -7
- 9x = -9
- x = -1
<u>Find the value of y:</u>
- y = -3(-1) - 1
- y = 3 - 1
- y = 2
The numbers are -1 and 2
Answer:
0.65g
Step-by-step explanation:
Decay rate = 50%
Decay rate = 0.5
where Ao = initial amount at start, k = rate of decay or growth, t = time, e = euler's number and A = value at time 't'
Ao = 4.8
t = 88/44 = 4
k = 0.5
substitute these values in the equation

Answer:
Milk: 2 cups
Flour: 5 cups
Sugar: 4 cups
Step-by-step explanation:
(First divide all ingredients by 2)
Milk: 3 -> 1.5
Flour: 5 -> 2.5
Sugar: 6 -> 3
(Next, multiply all by 4)
Milk: 1.5 -> 6
Flour: 2.5 -> 10
Sugar: 3 -> 12
(Divide by 3)
Milk: 6 -> 2
Flour: 10 -> 5
Sugar: 12 -> 4
