nico works in a lab and needs 30 liters of an 18% acid solution. He has two bottles of the same acid, one as a 10% and the other as a 25%.solution write and solve a system of equations and decide how many liters of the 10% solution and a 25% solution Nico should mix together to have 30 of an 18% solution

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

where is the diagram? shown below where? ?
