Answer:
Basically that’s saying 3 • 5 - 1 which will equal 14
Step-by-step explanation:
3•5 = 15 - 1 = 14
4x+(-3)=-2x-5
4x-3 = -2x-5
add 2x to each side
6x-3 =-5
add 3 to each side
6x = -2
divide by 6
x = -2/6
divide top and bottom by 2
x = -1/3
So you would distribute what's in the parenthesis and end up with 4x-2x-6=x+1, then you combine like terms and end up with 2x-6=x+1, now you can add 6 to both sides or subtract 1 both sides (basically anything goes for this step just make sure you apply the same thing on both sides) so I'll add 6 and continue just to show you... then you end up with 2x=x+7 then you subtract 1x on both sides to get x=7. sorry it's a lot hopefully you get it know!
Answer:
- principal: $7000
- interest rate: 3%
Step-by-step explanation:
amount repaid = principal + interest
$7840 = principal + $840
$7000 = principal . . . . . . . . subtract $840 from both sides of the equation
___
I = Prt
840 = 7000·r·4
840/(4·7000) = r = 0.03 = 3%
The principal was $7000; the interest rate was 3%.
For the first one. An equilateral triangle is one with three equal sides. An isosceles triangle is one with two equal sides. Therefore, every equilateral triangle is isosceles, but not every isosceles triangle is equilateral. So far, so book.
For the second one. Right triangles are defined as triangles that contain a right angle, where a right angle is an angle with a measure of 90°. Isosceles triangles are defined as triangles that have two sides of equal length.
