Answer the answer is A
thank you have a good day
Step-by-step explanation:
Answer:
1 × (3x + 2y = 12)
2 × (4x - y = 5)
3x + 2y = 12
+ (8x - 2y = 10)
= 11x = 22
divide both sides by the coefficient of 'x' (11)
Therefore x = 2
put (x = 2) in equation 1
3(2) + 2y = 12
6 + 2y = 12
2y = 12 - 6
2y = 6
divide both sides by the coefficient of 'y'(2)
Therefore y = 3
-10x+y=4
u just need to plug in values of x in function to get y values
x=-2
-10(-2)+y=4
20+y=4
y=-16
-10x+y=4
x=-1
-10(-1)+y=4
10+y=4
y=-6
-10x+y=4
at x=0
-10(0)+y=4
y=4
u are getting y values according to x values
y=-16 at x=-2
y=-6 at x= -1
y=4 at x=0
next u can find
Answer:
$68.44 will be the total bill.
Step-by-step explanation:
18/100 = .18
58 x .18 = 10.44
58 + 10.44 = 68.44

Answer:
c = 208.8
Step-by-step explanation:
a.
<em>To solve for C, you need to get the variable on one side of the equation and the numbers on the other side of the equation.</em>
b.
<em>You need to move the 7.2 to the other side. So, </em><em>multiply</em><em> both sides by 7.2, because it's being divided, so multiplying will cancel it out.</em>
c:
<em>Then, multiply 7.2 by 29. (The * symbol means multiply)</em>
d. c. = 208.8 <em>The answer is 208.8, which is rounded to the tenths place.</em>
Hope this helps! I tried to explain it in detail. :)
