Answer:
x = 60
Step-by-step explanation:
to solve this simple expression, you will collect the like terms and then evaluate for the value of x
<u>solution</u>
8.4 + 0.18x =0.32x
8.4 = 0.32x - 0.18x
8.4 = 0.14x
divide both side by the coefficient of x
8.4/0.14 = 0.14x/0.14
60 = x
x = 60
to check if the answer is correct put the value of x = 60 into the question and check if the right handside is equal to the left handside.
8.4 + 0.18x =0.32x
8.4 + 0.18 × 60 = 0.32 × 60
8.4 + 10.8 = 19.2
19.2 = 19.2................................................................................ proved
What is the chance of pulling a mechanic
T=months so if you have 7 months you would plug 7 in for (t)
making the equation g(7) = 2(7)
Answer:
ΔABC is not a right- angled triangle
Step-by-step explanation:
Given AB = 8, BC = 5
Then AC = 22 - (8 + 5) = 22 - 13 = 9 cm
Using the converse of Pythagoras' identity
If the square of the longest side equals the sum of the squares of the other 2 sides then triangle is right.
AC² = 9² = 81
AB² + BC² = 8² + 5² = 64 + 25 = 89
81 ≠ 89, hence ΔABC is not right- angled
