In this case, since one equation is in the form of x=, substitution would be best for this problem. Simply plug in 4y + 8 in place of x in the second equation, solve for y, then plug that value into the first equation to find x.
Right angles will be formed because in drawing
the perpendicular lines they all form right angles
to begin with. With several more draw it will
still be the same as if you are drawing one
the answer is -right angles
The correct answer is A. x=22
Since the angles of a rectangle are right angles (90 degrees) you would set it up as 90=5x-20. Then combine like terms and solve the equation. (If you need me to show you how step by step tell me)
Answer:
16) 18.5 hours
Step-by-step explanation:
40gifts = 5hrs
40/5 = 8
8gifts = 1hr
148/8 = 18.5
In 18.5 hours, 148 gifts are wrapped.
hope this helps and is right. p.s. i really need brainliest :)
Fraction would be 30/100 and decinal would be .30 and ratio would be 30/100
