Just use the equations x + y= 47 and 2x + 4y=138 to solve
Answer:
The answer is 30.66, mark me as brainliest
Answer: A. 75
Step-by-step explanation: Hope this help :D
Evaluate for x=10
(4)(10)+5(10−3)
(4)(10)+5(10−3)
=75
Answer:
Only the second equation is an identity
Step-by-step explanation:
<u>Note that </u>
<u>You can confirm it: </u>
<u>Therefore</u>
<h2>
It is not an Identity</h2>
<u>Let's the second one</u>
In this case, we already performed the calculations, so it is true. It is an Identity.
0.6 = 0.60
0.58 is 2 smaller than 0.6, so 0.6 is bigger
20% = 1/4 = 20, £80 + £20 = £100
20% = 1/4 = £600 - £20 = £580
