Answer:
y=6 x=8.49
Step-by-step explanation:
Since angles p and r are 45deg QP and QR are the same length.
the pythagorean theorem states that a^2+b^2=c^2.
so 6^2+6^2=72
the square root of 72 is 8.49.
so x or c = 8.49
Answer:
the point is now (2,2) because down is y and right is c
Answer:
28
Step-by-step explanation:
let the missing number be x
x÷2+49=2¼x
49=9/4x-x/2
lcm=4
9x-2x/4
49=7x/4
49×4=7x
196=7x
divide both sides by 7
196/7=x
therefore 28=x
<em><u>Question:</u></em>
At the market, 5 light bulbs cost $9. How much do 7 light bulbs cost?
<em><u>Answer:</u></em>
Cost of 7 bulbs is $ 12.6
<em><u>Solution:</u></em>

Find the cost of 1 bulb
Cost of 1 bulb is found by dividing the cost of 5 bulbs by 5
Thus cost of 1 bulb is $ 1.8
<h3><u>Find the cost of 7 bulbs:</u></h3>
Thus cost of 7 bulbs is $ 12.6
