Answer:
The value of k = 20 for equation 2(4x+10)=8x+k to have infinitely many solutions.
Step-by-step explanation:
Given the expression
solving
We know that the equations with infinitely many solutions have the same expressions on both sides
It means the value of k can be determined by further simplifying such as
8x+20-8x = k
20 = k
Therefore, the value of k = 20 for equation 2(4x+10)=8x+k to have infinitely many solutions.
VERIFICATION:
Given
Put k = 20 in the equation
equations with infinitely many solutions have the same expressions on both sides.
This means the statement is always true.
Answer = 8/7
You add 1 to both sides
Then simplify 7+1 to 8
Divide both sides by 7
This can be solve by first solving the proportionality constant
Number electic outlets rewired is directly proportional to
time spent
4 = (1 ½)a
Let be the proportionality constant
A = 8/3
O = (8/3)(7.5)
o = 20 outlets will jamal rewired if he works for 7.5 hrs
Answer:
A
Step-by-step explanation:
Classify each of the following sums as rational or irrational.
3÷5 + √3 = Irrational can't be written as a ratio of two integer numbers.
3÷5 + √4 = 3÷5 + 2 = (3 + 2*5)÷5 = 13÷5 Rational can be written as a ratio of two integer numbers.
2÷3 + √6 = Irrational can't be written as a ratio of two integer numbers.
2÷3 + √1 = 2÷3 + 1 = (2+3)÷3 = 5÷3 Rational can be written as a ratio of two integer numbers.
2÷9 + √2 = Irrational can't be written as a ratio of two integer numbers.
2÷11 + √9 = 2÷11 + 3 = (2+11*3)÷11 = 35÷11 Rational can be written as a ratio of two integer numbers.
Hope this helps!
