Answer:
-26= -9x + 10
-26 - 10= -9x
-36=-9x
-36:(-9)=x
4=x
Step-by-step explanation:
1. you pass +10 to the left in minus
2. you resolve what you've got on the left
then you pass the multiplying -9 to the left dividing
Answer:
2500pi^2 units
Step-by-step explanation:
Circumference = pi * diameter
Circumference = pi * 100
Radius = diameter/2
Radius = 50
Area = pi * radius^2
Area = pi * 50^2
Area = pi * 2500
Area = 2500pi^2 units
Answer:
3.6 qt. and 2.4 qt respectively
Step-by-step explanation:
Let x be x% of 50% saline solution. And (100-x%) be the percentage of 60% saline solution.
54=x*(50/100)+(100-x)*(60/100), solving it we will get x=60%. So we need 3.6 qt. of 50% saline solution and 2.4 qt. of 60% saline solution
Answer:
Step-by-step explanation:
3/7x=33
multiply each side by 3/7
x=99/7
x=14.142
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!!!!!!
