my answer is 468
2. On three consecutive passes, a football team gains 6 yards. loses 17 yards and gainbs 31 yards. Wht number represents the total net yards.
The total net years is 20 yards.
3. Solve
8x-(4x+4)=2
The solution is x=2
Amy paid $83.12 for a pair of running shoes during a 35%-off sale. What was the regular price.
The regular price was $127.90
1. and 2. are correct.
3.
8x-(4x+4)=2
8x - 4x - 4 = 2
4x = 2 + 4
4x = 6
x = 6/4
x = ?
4.
My answer is 2 cents less than yours.
i got 6/4 to
but if u divid it by to then its 3/2
1. Simplifying the expression 6[86-(94-86)]:
To simplify this expression, we need to perform the operations within the parentheses first.
Inside the parentheses, we have (94-86) which is equal to 8. So, we can replace (94-86) with 8.
Now the expression becomes 6[86-8].
Next, we can subtract 8 from 86, which gives us 78.
Now, we have 6 multiplied by 78, which is 468.
Therefore, the simplified expression is 468.
2. Finding the total net yards:
In order to find the total net yards, we need to add the gains or subtract the losses from the previous gains or losses of the football team.
Given three consecutive passes: gain of 6 yards, loss of 17 yards, and gain of 31 yards.
We can add these together:
6 + (-17) + 31 = 20
The negative sign in front of 17 represents the loss. Adding a negative value is equivalent to subtracting it.
Therefore, the total net yards are 20.
3. Solving the equation 8x - (4x + 4) = 2 for x:
First, we can simplify the expression inside the parentheses by adding 4x and 4, giving us 8x - 4x - 4 = 2.
Now we can combine like terms: 4x - 4 =2.
To isolate x, we can add 4 to both sides of the equation: 4x = 2 + 4 = 6.
Finally, we divide both sides by 4: x = 6/4 = 3/2 = 1.5.
Therefore, the solution to the equation is x = 1.5.
4. Calculating the regular price of the running shoes:
Amy paid $83.12 for the shoes during a 35%-off sale. To find the regular price, we need to reverse the discount.
First, we calculate the discounted amount by multiplying the sale percentage (35%) by the discount price:
35% of $83.12 = 0.35 * $83.12 = $29.09.
Next, we subtract the discounted amount from the sale price to get the regular price:
$83.12 - $29.09 = $54.03.
Therefore, the regular price of the running shoes was $54.03.
