8 x 3.10 = 24.80
She spent $24.80 all together
Answer:
500
Step-by-step explanation:
5000 divided by 10
The solution for v-9v+49=-2(v-7) is or 5.83(decimal form)
<u>Solution:</u>
Solving right hand side: multiply -2 with terms inside the bracket
v - 9v + 49 = -2v + 14
Move the terms from right hand side to left hand side. On moving a negative signed number from RHS to LHS, it becomes positive signed number.
Similarly, moving positive signed number from RHS to LHS, it becomes negative signed number.
v - 9v + 49 + 2v - 14 = 0
v -9v + 2v + 49 - 14 = 0
-8v + 2v + 49 - 14 = 0
-6v + 35 = 0
-6v = -35
Negative sign on numerator and denominator cancels each other
v = 5.83
