Answer:
where is the expression? please provide an expression.
It would be the second fifth and sixth one
Answer:
EF = 26
Step-by-step explanation:
From the question, we have that arc EF and arc CD are equal
what this indicates is that the line that bounds these arcs too will be equal
Hence, CD equals EF
Thus;
9x-1 = 41-5x
9x + 5x = 41 + 1
14x = 42
x = 42/14
x = 3
Recall;
EF is 41-5x
EF = 41-5(3)
EF = 41-15
EF = 26
The total hours Suzette biked was 2.5 hours and she ran for 1.5 hours
Let x = total hours Suzette ran.
Let y = total hours Suzette biked
The equation to solve the question will be:
x + y = 4 ....... equation i
6.5x + 14y = 44.75 ........ equation ii
From equation i, x = 4 - y ....... iii
Put the value of x into equation ii
6.5x + 14y = 44.75
6.5(4 - y) + 14y = 44.75
26 - 6.5y + 14y = 44.75
Collect like terms
-6.5y + 14y = 44.75 - 26
7.5y = 18.75
Divide through by 7.5
7.5y/7.5 = 18.75/7.5
y = 2.5
Since x + y = 4
x + 2.5 = 4
x = 4 - 2.5
x = 1.5
Suzette ran for 1.5 hours
In conclusion, the total hours Suzette biked was 2.5 hours and she ran for 1.5 hours.

Answer:
Step-by-step explanation:
If x is an odd integer, the next greater odd integer is x+2. The product is said to be 63, so the equation is ...
x(x +2) = 63
__
The equation can be rewritten as ...
(x +1)² = 64
x = -1 ±√64 = -1 ±8
The positive solution is x=7, so the positive set of integers is {7, 9}.
The negative solution is x=-9, so the negative set of integers is {-9, -7}.
