Answer: 84
Explanation:
Total for 5 tests = 80 x 5 = 400
Total for 4 tests = 84 + 75 + 81 + 76 = 316
5th score = 400 - 316 = 84
Answer:
x ≥6
Step-by-step explanation:
Given the product:
√(x-6)*√(x+3)
The function has to be defined if x ≥0
Hence;
√(x-6)*√(x+3)≥0
Find the product
√(x-6)(x+3)≥0
Square both sides
(x-6)(x+3)≥0
x-6≥0 and x+3≥0
x≥0+6 and x ≥0 - 3
x ≥6 and x ≥-3
Hence the required inequality is x ≥6
Simply double 12 (times by 2), then subtract 5 from your product.
12 x 2 = 24
24 - 5 = 19

Answer: 30 months
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
Matthew's saving account money (1500) must be equal to the product of the amount he pays per month for the app subscription (20) and the number of months (x); plus the product of the amount he pays per month for the Italian restaurant subscription (30) and the number of months (x).
1500= 20x+30x
Solving for x:
1500=50x
1500/50 =x
30 months =x

A1/27 = A2/39 =>
A2 = A1*39/27
A2 = 711×39/27
A2 = 1027 m^2
