Answer:
the answer would be 40
Step-by-step explanation:
Well since the first expression says 8x(40+7) the answer would be 40 that is missing
Since your splitting 47 into 40 and 7 and multiplying both of them by 8 the answer would be 40
Answer: 42
Step-by-step explanation:
Here given numbers : 28 and 63
so Mean = √x * y
let x = 28 and y = 63
<em>So mean proportion between them is:</em>
M = √63 * 28
M = √1764
M = 42
- therefore the mean proportion between 28 and 63 is 42

Answer:
a) 7(8)+9 (12)
b)7x+45
c )10 hours
Step-by-step explanation:
Hi, to answer this question we have to write an expression
The amount earned by Jason must be equal to the product of the amount he earns per hour during the week (7) and the hours worked during the week (x) ; plus the product of the amount he earns per hour during the weekend ( 9) and the hours worked during the weekend (y):
7x+ 9y
a) substitute x=8 and y=12
7 (8)+ 9 (12)
b) substitute y =5
7 x +9(5) =
7x+ 45 =
c)
Substitute y=5 and the expression must be equal to the amount he needs to buy sports equipment (115):
7x+9 (5)=115
Solving for x:
7x + 45 =115
7x = 115-45
7x = 70
x =70/7
x =10 hours
Answer:
B
Step-by-step explanation:
1/25 = 0.04 only. this is surely the anwer
2^x = 5
-> log2^x = log5
-> xlog2 = log5
-> x = log5/log2
-> x = 2.322
The approximate answer is 2.322
