Answer:
x<13
Step-by-step explanation:
1. Move variable [x] to left-hand side and change its sign
Move constant [10] to the right-hand side and change its sign
10>x-3
-x+10>-3-10
2. Calculate the difference [-3-10]
-x>-3-10
-x>-13
3. Change the signs [-x>-13] on both sides of the inequality and flip the inequality sign
x<13
4. Solution
x<13
Answer:
-4
Step-by-step explanation:
8+4y= -8
4y= -8 -8
4y= -16
divide both sides by the coeffient of the variable. in this case divide both sides by 4
y=-4
Answer:
105 cc of 7% solution
245 cc of 17% solution
Step-by-step explanation:
If x = volume of 7% solution, and y = volume of 17% solution, then:
x + y = 350
0.07x + 0.17y = 0.14(350)
Solve with substitution:
0.07x + 0.17(350 − x) = 0.14(350)
0.07x + 59.5 − 0.17x = 49
10.5 = 0.10x
x = 105
y = 245
