-6=-7+x
Make the variable to the left hand side and change it’s sign.
-6-x=-7
Move the constant to the right hand side and change its sign.
-x=-7+6
Calculate the sum
-x=-1
Change the signs of both sides of the equation .
X=1
If you take away the 0s you can multiply 8 and 3. sooooo
3x8=24
Answer:
65°
Step-by-step explanation:
Sum of interior angles of a triangle = 180°
⇒ m∠EAB = 180 - 90 - 70 = 20°
⇒ m∠DAG = 90 - 45 - 20 = 25°
⇒ m∠AGD = 180 - 90 - 25 = 65°
ΔADG ≅ ΔAFG
⇒ m∠AGD = m∠AGF = 65°
ΔABE ≅ ΔAFE
⇒ m∠AEB = m∠AEF = 70°
Answer:
y=2x+6 ; x+y=51
Step-by-step explanation:
assuming x is one number and y is the other -
one number (y) is 6 more (+6) than twice another (2x) -
using that knowledge we form an equation -
y=2x+6
the sum (x+y) is 51
using this knowledge we can make the equation -
x+y=51
now you have -
y=2x+6 or 2x-y=-6
x+y=51
using system of equations -
you add the equations -
3x=45
x=15
y=51-x => y=36
hope this helps!!
Answer:
Concept: Percentage Addition
- Your original price is 7.70
- It increased by 60%
- Hence you do 7.70 * .60 = x
- Whatever you get from (3) you add it to 7.70+x to get your final price
