Answer:
(5c-9-a)/3
Step-by-step explanation:
1. subtract a from both sides to isolate the variable and its coefficient
5c-9-a = 3b
2. divide both sides by 3 to isolate b because 3b/3 = b
(5c-9-a)/3 = b
Answer:
C
Step-by-step explanation:
A proportional graph is a line. Every line has a slope. The slope is found by subtracting two points as a ratio. The line has points (0,0) and (2,6).
6-0 = 6
2 -0 = 2
The ratio is vertical over horizontal so 6/2 = 3.
The equation is y = 3x.
Step-by-step explanation:
π= 3.14
Given
Circumference = 12.56 units
First calculating radius
so 2πr = 12.56
2 * 3.14 * r = 12.56
6.28 r = 12.56
Therefore r = 2 units
Now calculating Area
Area = πr²
= 3.14 * 2²
= 12.56 square units
Answer:
5.9 × 10⁻¹⁶
Step-by-step explanation:
To solve this, you need to convert one of the two numbers to the same power of ten as the other. We can do that by multiplying the first number by 10:
6.7 × 10⁻¹⁶ - 8.2 × 10⁻¹⁷
= 67× 10⁻¹⁷ - 8.2 × 10⁻¹⁷
= (67 - 8.2) × 10⁻¹⁷
= 58.8 × 10⁻¹⁷
= 5.9 × 10⁻¹⁶
Note that we're rounding to the nearest tenth, as the original numbers given were as well.
Answer:
The correct graph answer is A.
Step-by-step explanation:
Let
c ----> the total cost to rent a set of hand tools
h ----> the number of hours for the rental
we know that
The linear equation that represent the problem is equal to
---> this is the equation of the line into slope intercept form
where
the slope m is equal to
m=$2 per hour
b=$2 ---> the y-intercept (the value of c when the value of h is equal to zero)
therefore
The correct graph is A.
B. C. and D. are incorrect
