How do you solve -5n-8(1+7n)=8
Answers
Let's simplify everything.
-5n-8-56n=8
Put the variables on one side and the numbers on the other.
-5n-56n=8+8
Combine like terms.
-61n=16
n=-16/61
Hope I helped! :)
-5n - 8 - 56n = 8
-61n = 8 + 8
-61n = 16
n = - 16/61
The answer is: n = -16/61 or n = -0.2623.

=> Vases costs = 3.59 dollars each
=> each total of sales tax = 1.34 dollars each
The total amount she paidis 28.50 dollars including the tax.
Simply add the price of vase and sales tax each then add.
=> 3.59 + 1.34 = 4.93
=> 4.93 * 2 = 9.86 (times 2 because there are 2 vases)
Now, subtract this with the total amount she paid.
=> 28.50 – 9.86 = 18.64
Since there are 4 glass beads, divide this by 4
=> 18.64 / 4 = 4.66 , the price of glass beads with tax.

a and b are legs
c=hypotnuse
a^2+b^2=c^2
10^2+b^2=10^2
100+b^2=100
minus 100 both sides
b^2=0
b=0
false, if you have a leg legnth 0, then they lines are right on top of each other
no cannot
To solve this problem we have to use the Pythagorean theorem. You can only use the Pythagorean theorem in Right Triangles. The longest side of the triangle is called the "hypotenuse". C² is the longest side so it is the hypotenuse . To calculate c² we have to do α² + β² = c².
Given
α² = 10
c² = 10
Solve
α² + β² = c²
α² (10²) + β² = c² (10²)
100 + β² = 100
β² = 100 - 100 = 0
Simplify
A right triangle can not have a leg that is 10 meters long and a hypotenuse that is 10 meters long.
