Answer:
16 for Sol A and 24 for Sol B
Step-by-step explanation:
Let x = the number of ounces of Solution A
Let y = the number of ounces of Solution B
x + y = 40 y = 40 - x
.60x + .85y = .75(40)
.60x + .85y = 30 Multiply both sides of the equation by 100 to remove the decimal points.
60x + 85y = 3000
60x + 85(40 - x) = 3000
60x + 3400 - 85x = 3000
-25x = -400
x = 16 ounces
y = 40 - 16
y = 24 ounces
Answer:Linear pair and X is 23
Step-by-step explanation:
Answer:
First you right the division as a fraction
1/5x=5
then mutiply both sides of the equation by 5
x=25
Step-by-step explanation:
Complementary angles add to 90o
the other angle = x
the first angle = 3x - 4
x + 3x - 4 = 90
4x - 4 = 90
4x = 94
x = 94/4
x = 23.5
the first angle = 3*23.5 - 4 = 66.5
Answer: x=50
Explanation:-
Exterior angles of all polygons add up to 360 degrees.
So, x+20+x+40+2x+2x=360
x+x+2x+2x+20+40=360
6x+60=360
6x=360-60
.:6x=300
x=300/6
x=50
