247 is equal to 200+40+7.
358 is equal to 300+50+8.
To find the answer, add 200+300=500.
40+50=90
7+8=15
500+90+15=605
The answer is 605.
Answer:
if the other lines are parallel or not.
Step-by-step explanation:
Answer:
This is a -29.6% change
Step-by-step explanation:
To find the percent change, use the percent change equation.
(New - Old)/(Old) * 100 = Percent Change
(126 - 179)/(179) * 100 = Percent Change
-53/179 * 100 = Percent Change
-.296 * 100 = Percent Change
-29.6% = Percent Change
5x + 6y = 7 SUBSTITUTION METHOD
2x + 2y = 4
5x + 6y = 7 Solve for either x or y in 1 of the 2 equations.
- 6y - 6y
-----------------------
5x = -6y + 7
----- ------ ----
5 5 5
x = -6/5y + 7/5
2(-6/5y + 7/5) + 2y = 4 Substitute the expression you got for x or y into
-12/5y + 14/5 + 2y = 4 the other equation.
-2/5y + 14/5 = 4
- 14/5 - 14/5
------------------------------
-2/5y = 6/5
-------- --------
- 2/5y - 2/5y
y = -3
5x + 6(-3) = 7 Plug in the value you got for y in step 2 into the
5x - 18 = 7 equation that you didn't use.
+ 18 + 18
------------------
5x = 25
--- -----
5 5
x = 5
(x,y) ⇒ coordinate
(5,-3) ⇒ final answer
