Answer:
a = -2
Simplifying 5 + -2(4a + 1) + 3a = 13 Reorder the terms: 5 + -2(1 + 4a) + 3a = 13 5 + (1 * -2 + 4a * -2) + 3a = 13 5 + (-2 + -8a) + 3a = 13 Combine like terms: 5 + -2 = 3 3 + -8a + 3a = 13 Combine like terms: -8a + 3a = -5a 3 + -5a = 13 Solving 3 + -5a = 13 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -5a = 13 + -3 Combine like terms: 3 + -3 = 0 0 + -5a = 13 + -3 -5a = 13 + -3 Combine like terms: 13 + -3 = 10 -5a = 10 Divide each side by '-5'. a = -2
Answer:
how many rubys are there
Step-by-step explanation:
Answer:
<h2>52500 kg</h2>
Step-by-step explanation:
Step one:
given data
mass of harvested peanuts = 14,000kg
size of land = 8-acre
Step two:
Required:
mass of harvested peanuts for a 30-acre land
let the mass be x
so, for 8-acre land the harvested mass is 14,000
hence for 30-acre land the harvested mass is x
cross multiply we have
8x=14,000*30
divide both sides by 8
x=420000/8
x=52500 kg
Answer:
{x | x ≤ -20}
Step-by-step explanation:
x + 17 ≤ -3
Subtract 17 from each side
x + 17-17 ≤ -3-17
x ≤ -20
