Answer:
x = -1
Step-by-step explanation:
1/4 (4x - 4) = -2(6x + 7)
1x - 1 = -12x - 14
13x = -13
x = -1
Answer:
36 millimeters
Step-by-step explanation:
From Pythagoras theorem, the square of the hypotenuse is equal to the sum of the square of the two other legs
In mathematical terms;
a^2 = b^2 + c^2
Let a represent the hypotenuse = 39 mm and the length of one leg, say c, is 15 mm
Slotting in the values of a and b
39^2 = b^2 + 15^2
1521 = b^2 + 225
collect like terms
1521 - 225 = b^2
1296 = b^2
Take the square root of both sides
36 = b
Therefore b = 36 mm
Answer: 1.8
Step-by-step explanation:
Answer: $2184
Step-by-step explanation:
2.8% interest annaully
Deposit $6500
Annaully interest
2.8% x $6500 / 100
= $182
Interest after 12 years.
Principal x Rate x Time/100
= $6500 x 2.8% x 12 /100
= $2184
