Answer:
3: x = 3 4: y = 8
Step-by-step explanation:
Problem 3:
Because of the lines on each side of the rhombus, that shows you that all of those lines are congruent with each other, meaning they are all the same length. So since one side equals the other, you can equal one of the equations on one side to another equation on another side. EX: x+5 = 3x-1. And then you solve that through multi-step equations.
Problem 4:
Just like on Problem 3, due to the little dashes going through the sides of the rectangle, the sides are congruent (the same length) as one another. Except the sides with one dash are not congruent with the sides with two dashes. But if you equal 2y and y+8, then you can solve that through multi-step equations again and get y = 8 since they are congruent with each other (due to the singular dashes running through their sides).
Hope this helped!
Answer:
16
Step-by-step explanation:
Perimeter = distance round the shape
2y + 11 + y + 3 +3y - 2 + 10 = 58
Collect like terms
2y + y + 3y = 58 - 11 - 3 + 2 - 10
6y = 36
y = 36/6
y = 6
Length PQ = 3y - 2 = 3(6) -.2 = 18 - 2 = 16
Answer:
James still owes 1,261 dollars after 12 months
Step-by-step explanation:
<u>Second attempt :P</u>
James currently has 215 dollars, every month for 12 months, he deposits 45 dollars into his account
215 + 12 x 45
215 + 540 =755
Now we know how much money James will have after 12 months, we need to find out how much he will owe.
James has to pay 168 per month for 12 months
168 x 12 = 2016
After 12 months the total amount James owes will be 2,016 dollars.
He makes 755 for the whole 12 months
2,016 - 755 = 1,261
James still owes 1,261 dollars after 12 months
Answer: y = -5/6 x - 1
Step-by-step explanation:
The slope is -5/6, which is why x = -5/6. The - 1 is so the line on the graph will pass through (0,-1) and (-6,4).
