Answer:

x = 4

y = 11

Step-by-step explanation:

Set your formula as follow:

2x+3=3x-1 -> 2x+3-3x=-1 -> -x+3 = -1 -> -x=-4 -> x=4

now substitute x for 4 in the following

y-2=2(4)+1 -> y-2=8+1 ->y-2 = 9y -> y=11

A shopper purchased 4 tables and 2 chairs for $200 and 2 tables and 7 chairs for $400. What is the cost of each table and each c

I am Lyosha [343]

4t+2c=200
2t+7c=400

I will solve for c in terms of t first
4t+2c=200
2c=200-4t
c=100-2t

Then I will substitute this in for c in the second equation to make it single variable
2t+7c=400
2t+7(100-2t)=400
2t+700-14t=400
300t=12
t=25
Tables cost $25 each

Plug t back into one of the ORIGINAL equations to find the cost of chairs
4(25)+2c=200
100+2c=200
2c=100
c=50
Chairs cost $50 each

Hope this helps! :)

Parallel lines x and w are cut by transversals z and y and form 4 angles at each intersection. Where line x intersects with line

ale4655 [162]

Answer:

$m\angle 1 =105^\circ\\m\angle 2 =75^\circ$

Step-by-step explanation:

The diagram is drawn and attached below.

From the diagram

$m\angle 2 =75^\circ $ (Alternate Angles)$

$m\angle 1+ m\angle 2 =180^\circ $ (Sum of angles on a straight line)\\m\angle 1+75^\circ =180^\circ\\m\angle 1 =180^\circ-75^\circ\\m\angle 1 =105^\circ$
