A) 24 ribbons
B)1/28yards
11.u have 1/2 how?
Answer:
10
Step-by-step explanation:
let x = unknown number
three times x is increased by 24
so 3x + 24
this is equal to 16 less than 7 times x
so 3x + 24 = 7x - 16
we now solve for x
3x + 24 = 7x - 16
add 16 to both sides
3x + 24 + 16 = 7x - 16 + 16
3x + 40 = 7x
subtract 3x from both sides
3x - 3x + 40 = 7x - 3x
40 = 4x
divide both sides by 4
40/4 = 10
4x / 4 =x
x=10
the unknown number is 10
4x+30=90
-30 -30
4x=60
X=15
There could be a one to all solution,One to one solution or no solution or all to one solution
