Answer:
$2.20
Explanation:
For every mile $0.20 is charged
The base fee is $2.00
If you travel 1 mile, you get charged $0.20 along with the base fee of $2.00
2.00 + 0.20 = 2.20
Answer:
2+4y
Explanation:
The height of the tree increases by 4 feet per year, so we know to multiply 4 by the number of years to find its height. The initial height of the tree is 2, so we add 2 to 4y.
Example: The height of the tree in 6 years
2+4y
2+4*6
=2+24
=26
I hope this helps!
Answer:
x = 8
y = -3
Step-by-step explanation:
Multiply the first equation with (-2)
(-2) * (x - 4y) = 20
-2x + 8y = -40 now find the sum of it with second equation
2x + 5y - 2x + 8y = 1 - 40 add like terms (2x will eliminate -2x)
13y = -39 divide both sides by 13
y = -3
Now we can use this to find the value of x
x - 4y = 20 rewrite the equation using the value we found for y
x - 4(-3) = 20 multiply (-4) and (*3) (product will be positive because we are multiplying two negatives)
x + 12 = 20 subtract 12 from both sides
x = 8
Answer:
If scale factor of any object is ![\[x\]](https://tex.z-dn.net/?f=%5C%5Bx%5C%5D)
then all dimensions multiplied by .
Step-by-step explanation:
• The dimensions of Jessica’s room is given that is 10 ft and as the mentioned above , scale factor multiplied with dimensions to give the actual dimensions.
• Therefore new dimensions of Jessica’s room is ![\[10.(2)=20ft\]](https://tex.z-dn.net/?f=%5C%5B10.%282%29%3D20ft%5C%5D)
