Answer:
0,95
Step-by-step explanation:
Answer:
A.) x / 3 = 12 ----> x = 12(3) ----><em> </em><em>x = 36</em>
B.) 2x + 3 = 20 ----> 2x = 17 ----> x = 17/2
C.) 4/3x = 10/3 ----> x = 10/3 x 3/4 ----> x = 30/12 = 5/2
D.) -4x = -24 ----> x = -24/-4 ----> x = 6
E.) 2(x-4) = 10 ----> 2x - 8 = 10 ----> 2x = 18 ----> x = 9
F.) -0.5x + 1.1 = -2.9 ----> -0.5x = -4 ---> x = -4 / -0.5 ----> x = 8
Answer:
8.9
Step-by-step explanation:
( 4.5 + 7.6 ) - 8/2.5
PEMDAS
Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction
Let's do the parenthesis first
( 4.5 + 7.6 )
12. 1
12.1 - 8/2.5
Now let's do the division next
8/2.5 = 8 ÷ 2.5
3.2
12.1 - 3.2
Now we can subtract that
12.1 - 3.2
8.9

A)The quotient of three times some number and five
Answer:
B 4i sqrt(2)
Step-by-step explanation:
sqrt(-2) = sqrt(-1) * sqrt(2) = i sqrt(2)
sqrt(-18) = sqrt(-1) sqrt(2) sqrt(9) = 3i sqrt(2)
Add them together
i sqrt(2) + 3i sqrt(2)
4i sqrt(2)
