Answer:
89
Step-by-step explanation:
1. She spent a total of 23 + 30 + 16 = 69 dollars.
2. That means she had at least 69 dollars to spend. But if it were 69 dollars, that would mean she had 0 remaining dollars because she spent it all.
3. But she had 20 dollars left after she spent the 69 dollars.
4. So that means she had 89 dollars before making the purchase
Answer:
−44.288−31.6
−3.1(6−1.2)
=
−75.888
−3.1(6−1.2)
=
−75.888
(−3.1)(4.8)
=
−75.888
−14.88
=5.1
5.1 is the answer
Step-by-step explanation:
Answer:
x = 49
Step-by-step explanation:
This is an inverse relationship and it implies that, an increase in the value of one variable results in a subsequent decrease in the value of another variable.
Given the mathematical expression and data;
y = 1/√x
y = 7 and x = 64
First of all, we would find the constant of proportionality, k;
y = k/√x
7 = k/√64
7 = k/8
k = 7 * 8
Constant, k = 56
Now, to find the value of x when y = 8
y = k/√x
Substituting the values, we have;
8 = 56/√x
Cross-multiplying, we have;
8 * √x = 56
√x = 56/8
√x = 7
Taking the square of both sides, we have;
(√x)² = 7²
x = 49
