Answer:
10x > 60
Step-by-step explanation:
The unknown here is the number which is multiplied by 10, so let that be x.
We know that this number is greater than 60. So put the greater than sign.
The answer in true hope this helps
Answer:
Step-by-step explanation:
area of the triangle
A=1/2 *b*h
A=1/2*2/5*6/5=6/25
Assume we need to add x litters.
So we are going to mix x liters (25% saline) and and 3 liters (10% saline).
In total we are going to have a x+3 litters (of 15% saline).
a. of the x liters, 25/100x=0.25x is saline. so we have 0.25x liters saline.
b. of the 3 liters, (10/100)*3=0.1*3=0.3 liters is saline.
c. of the x+3 liters, (15/100)(x+3)=0.15(x+3)=0.15x + 0.45 liters is saline
equalize:
0.25x + 0.3 = 0.15x + 0.45
0.25x - 0.15x = 0.45 - 0.3
0.1 x =0.15
x=0.15/0.1= 1.5 (liters)
Answer: 1.5 liters
The picture is exponential
