Answer:
a = 40
Step-by-step explanation:
This is a multi-step equation using the distributive property and rational coefficents (fractions). The first step is to complete the distributive property on both sides of the equation and multiply each term in the expression in parenthesis by the constant on the outside. (3/4 x 2a) - (3/4 x 6) +1/2 = (2/5 x 3a) + (2/5 x 20). When we multiply and simplify, we get 3/2a - 9/2 + 1/2 = 6/5a + 8. Next step is to combine like terms: 3/2a - 8/2 = 6/5a +8. We then need to isolate the variable by using inverse operations: 3/10a = 12, then solve for 'a' by multiplying both sides by the reciprocal (10/3) to get a = 40.
Answer:
Step-by-step explanation:
Given
Required
Determine the total number of markers
First, we need to determine the ratio of black to blue such that
Multiply the ratio by 5
By direct comparison:
The above shows that:
So:
Multiply both sides by 8. Then divide both sides by 3. Answer is 8/3
Answer:
B. 9.7 in.
Step-by-step explanation:
We have been given an image of a triangle. We are asked to find the value of x.
We will use area of triangle formula to solve our given problem.
Taking square root of both sides we will get,
Therefore, the value of x is 9.7 inches and option B is the correct choice.
