.90x = 12
x = 12/.9 = 13 1/3
Hope this helps :D
Answer:
CVS
Step-by-step explanation:
i am pretty sure
Answer:
a = 8/12 (2/3)
b = 4/12 (1/3)
c = 6/12 (1/2)
Step-by-step explanation:
a= 1-8 = 8 numbers less than 9
b= 3,6,9,12 = 4 numbers multiple of 3
c = 7-12 = 6 numbers higher than 7
Answer:
solution of the equation are x = 3 and x = ±√3
Step-by-step explanation:
Given in the question an equation
x² / (2x-6) = 9 / (6x-18)
Step1
cross multiplication
x²(6x - 18) = 9 (2x - 6)
Step2
apply distributive law
6x³ - 18x² = 18x - 54
step3
rearrange the terms
6x³ - 18x² - 18x + 54 = 0
step4
divide by 6
x³ - 3x² - 3x + 9 = 0
x²(x-3) -3(x-3) = 0
(x-3)(x²-3) = 0
Step5
x = 3 and x² = 3
for factor x² = 3
take square root on both sides
√x² = √3
x = ±√3
Answer:
y = -5
Step-by-step explanation:
-10(-1/2y + (-7/2)) + 7y = -25
Let's first of all expand the bracket to get;
5y + 35 + 7y = -25
12y + 35 = -25
12y = -25 - 35
12y = -60
y = -60/12
y = -5
