Answer:
6
Step-by-step explanation:
Multiply 7x+3 by 2. When you get 14x+6, set equal to 90 and solve for x.
Answer:
y = -3/4 + 4
Step-by-step explanation:
use rise over run to find slope
Answer:
see the explaination
Step-by-step explanation:
let x be 3:3:5
3x:3x:5x
3x is splice cookies
3x is snickerdoodle cookies
5x is no bake cookies
where 5x is equal to 45
x is equal to 45÷5=9
so x is equal to 9
now,
3x = 3×9=27
3x = 3×9=27
5x = 45 (given)
now add all, total cookies =27+27+45
=99 cookies
so there are total 99 cookies in a cookie mix
x^2b + t = x^2e
x^2e - x^2b = t
x^2(e - b) = t
x^2 = t /(e -b)
x = √[t /(e -b)] or x = - √[t /(e -b)]
