I think it’s the second one please correct me if I’m wrong not perfect at this
Answer:
1.488
Step-by-step explanation:
Let x be the price of a veggie wrap and y be the price of an apple.
2x + 3y = 6.24 [EQUATION 1]
3x + 2y = 6.64 [EQUATION 2]
[You need 2 equations for this question because there are 2 unknowns, the prices of a veggie wrap and an apple.]
[You can use elimination or substitution to calculate the equations. I'll just use elimination]
ELIMINATION:
[EQUATION 1 * 3] - [EQUATION 2 * 2]:
(2x + 3y)*3 - (3x + 2y)*2 = (6.24*3) - (6.64*2)
6x + 9y - 6x - 4y = 18.72 - 13.28
5y = 5.44
y = 1.088
[since y is the price of an apple and NOT a veggie wrap, you still need to find x]
sub (substitute) y = 1.088 into [EQUATION 1]
2x + 3(1.088) = 6.24
2x = 6.24 - 3.264
x = 1.488
An apple costs 1.088 and a veggie wrap costs 1.488.
Answer:
w = 48
w = 196
Step-by-step explanation:
Width = w
Length = l = 4 + 4w
Use the values for length and width above along with the given value for perimeter in the formula for perimeter.
P = 2l + 2w
488 = 2(4 + 4w) + 2w
488 = 8 + 8w + 2w
488 = 8 + 10w
488 - 8 = (8 + 10w) - 8
480 = 10w
(480)/10 = (10w)/10
48 = w
w = 48
The width is 48 yards. Use this value to solve for length.
l = 4 + 4w
l = 4 + 4(48)
l = 4 + 192
l = 196
The length is 196 yards.
Answer:

Step-by-step explanation:
Answer:
The answer is
<h2>
</h2>
Step-by-step explanation:
f(x) = 6x² + 3
To find the inverse of the function above equate it to y
That's
f(x) = y
So we have
y = 6x² + 3
Next interchange the variables that's x becomes y and y becomes x.
x = 6y² + 3
Next make y the subject
<u>Subtr</u><u>act</u><u> </u><u>3 </u><u>from</u><u> both sides</u>
That's
6y² + 3 - 3 = x - 3
6y² = x - 3
<u>Divide both sides by 6</u>
That's
<h3>
</h3>
<u>Next find the square root of both sides</u>
<h3>
</h3>
We have the final answer as
<h3>
</h3>
Hope this helps you
