Answer:
-17/10
Step-by-step explanation:
you have to find a common denomentaor first wich would be 10
then you have to mutiply -4/5 by 2 which would be -8/10
and then you would do regular subtraction
but since its a negative number your gonna actually add but then the final answer will be negative
-17/10
hope this helps I really suck with fractions
Well to find the values of the variables, you would have to use the Pythagorean Theorem. The Pythagorean Theorem states that a²+b²=c². A being one side of the triangle, b being the other side, and c being the hypotenuse. The hypotenuse is the slanted and the longest side of a right triangle. So let's find the the total amount of x and y. 5+7=12 Just plug in the numbers into the equation 12²+5²=c² C would equal 13. So we know that x+y=13. If we plug in 7 and 5 into the equation (solving for y) 7²+5²=c², C would equal 8.6. To find x just do 13-8.6 and we get 4.4. So we know that y=8.6 and x=4.4. Hope I helped!
Answer:
area equals to 1/2 a + b * height so I have divided 1/2 which I've taken to divide 4.4 + 3.2 which equals to 7.6 * 3 so 1/2 divide divide 7.6 is 3.8 .3.8 * 3 equals to 11.4 that's my answer 11.4 ft.

Answer:
A: 10.9
Step-by-step explanation: -2.3 is 2.3 away from zero then add the length from zero to the postive number which in this case is 8.6, therefore the equation is 2.3 + 8.6 = 10.9
