Answer:
c) x=1.23
Step-by-step explanation:
a =3
b=2
c=-7
use quadratic equation where
[tex] { ax}^{2} + bx + c = 0 = \frac{ - b \: + or \: - \sqrt{ {b} ^{2} - 4ac} }{2a} [/tex]
-2+/- square root of (2^2- (4×3×-7) ) all that over 2x3
square root of (2^2-(4×3×-7) )
= 9.38083152
2×3=6
-2+or - 9.38 all that divided by 6
-2+9.38= 7.38÷6
x=1.23
or
-2-9.38 all divided by 6
-2-9.38= -11.38 ÷6
x= -1.9
all in all x can't be negative meaning x=1.23

Answers
Answer:
x = -4 1/2
Step-by-step explanation:
-2x/3 + 11 = 14
subtract 11 from each side of the equation:
-2x/3 = 3
multiply both sides by 3:
-2x = 9
divide both sides by -2:
x = -4 1/2

Answers
Answer:
2, 262%, 5, 26.2
Step-by-step explanation:
Nuff said
Answer:
262%, 2/5, 26.2
Step-by-step explanation:
262% is more than 100%, therefore it is 1st.
2/5 is equal to 40%, which is greater than 26.2, but less than 262% so it is 2nd.
26.2 is less than the previous answers so it is 3rd.

Using the information that
5.2 x 67 = 348.4
write down the value of
c) 348.4 ÷ 52
Answers
Answer: 6.7
Step-by-step explanation:
We know that:
5.2*67 = 348.4
And we want to find the value of:
348.4/52 = x
So, let's return to the original equation.
5.2*67 = 348.4
Let's try to "construct" the quotient 348.4/52
The first step is to divide both sides by 5.2, then we get:
(5.2*67)/5.2 = 348.4/5.2
67 = 348.4/5.2
Now we have 5.2 in the denominator instead of 52, then we can divide both sides by 10 to get:
67/10 = ( 348.4/5.2)/10 = 348.4/(5.2*10) = 348.8/52
6.7 = 348.8/52
Then the solution to the quotient:
348.4/52 is 6.7
