x=4
Step-by-step explanation:
subtract 2 from both sides---
5x + 2 - 2 = 22 - 2
simplify ---
5x=20
Divide both sides by 5 -----
5x/5 = 20/5

x-4
hope this helps :)
<span>-2x^2-x+7=0
Variable with the highest degree's (exponent) constant, -2 is a, next variable's constant, -1 is b, the constant or number without a variable, 7 is c
using substitution put the numbers into the formula
</span>(-b±√(b^(2)-4ac))/(a^(2))
(-(-1)±√((-1)^(2)-4(-2)(7))/((-2)^(2)) simplify
(1±√(1+56))/4
1±√(57)/4 is your answer
Answer: I think it is b
Explanation:
10% of 35 is 3.5
20%= 7
50% = 17.5
25% = 8.75
10% of 250g is 25
10% of 350 is 35
10% of 205 is 20.5
10% of 305 is 30.5
lemme get the branliest
