Answer:
<h2>5</h2>
Step-by-step explanation:
Given the expression (8x² −15x)−(x² −27x) = ax² +bx, we are to determine the value of b-a. Before we determine the vwlue of b-a, we need to first calculate for the value of a and b from the given expression.
On expanding the left hand side of the expression we have;
= (8x² −15x)−(x² −27x)
Open the paranthesis
= 8x² −15x−x²+27x
collect the like terms
= 8x²−x²+27x −15x
= 7x²+12x
Comparing the resulting expression with ax²+bx
7x²+12x = ax²+bx
7x² = ax²
a = 7
Also;
12x = bx
b =12
The value of b - a = 12 - 7
b -a = 5
Hence the value of b-a is equivalent to 5
1 yard=3 feet so 100 yard=300 feet
Answer:
x + y = 162 and x = 2y - 6
Step-by-step explanation:
Let the total wins be x
Let the total loss be y
If a baseball team's total wins and losses for one season is 162, this can be expressed as;
x + y = 162 ....... 1
If the number of wins is 6 less than 2 times the number of losses, this is expressed as;
2 times the number of losses = 2y
6 less than 2 times the number of losses = 2y - 6
Now, If the number of wins is 6 less than 2 times the number of losses this is expressed as;
x = 2y - 6 .... 2
Hence the required system of equation are;
x + y = 162 and x = 2y - 6
Answer:
Without them, there would have been no United States of America.
The Founding Fathers, a group of predominantly wealthy plantation owners and businessmen, united 13 disparate colonies.
They fought for independence from Britain and penned a series of influential governing documents that steer the country to this day.
All the Founding Fathers, including the first four U.S. presidents, at one point considered themselves British subjects.
But they revolted against the restrictive rule of King George III outlining their grievances in the Declaration of Independence, a powerful call for freedom and equality.
They won a stunning military victory over what was then the world’s preeminent superpower.
