Answer:
$4, and $44
Step-by-step explanation:
10% of 40 = $4
40+4=$44
just mark 4 , 44 on number line
R - 5 1/6 = 10
r - 31/6 = 10
+ 31/6 +31/6
r = 91/6
So, r = 91/6.
And, I am not sure if the second one I am doing in right or wrong, but I am just guessing.
I think you use substitution method here.
8(x-2)+9 = 14
8x-16+9 = 14
8x-7 = 14
+7 +7
8x = 21
x = 21/8
So, the answer is 21/8
HOPE THID HELPS AND I REALLY HOPE THAT THE SECOND ANSWER IS RIGHT!!!!!!
So she earns $60 per day working, but only saves $50. To solve this equation you have to multiply $50 to each day she works. If the total has to be exactly $2,000 then you must multiply 50 x 36.4 and that equals $2,000.
Your answer should be 36.4 days.
Answer:
the correct answer is a. (x = 2, y = 1, z= -2).
you can try inserting each value to all three equations and you'll see that only "a" satisfies all equations.
Step-by-step explanation:
4x+4y+3z=6
4(2)+4(1)+3(-2) = 12-6 = 6
4x + 7y + 5z = 5
4(2)+7(1)+5(-2) = 15-10 = 5
5x + 3y + 3z= 7
5(2)+3(1)+3(-2) = 13-6 = 7
now, you can clearly see that all the equations are satisified with the help of the employment of the three values x=2 , y=1, and z = -2 which makes A the correct answer.
