Answer:
x = 21/2
y = -19/2
Step-by-step explanation:
5x - 17 = 4y + 7x
5x - 7x - 4y = 17
-2x - 4y = 17
6x + 8y = - 13
-2x - 4y = 17 | ×2 |
6x + 8y = - 13 | ×1 |
-4x - 8y = 34
6x + 8y = - 13
___________+
2x = 21
x = 21/2
-2x - 4y = 17
-2(21/2) - 4y = 17
-21 - 4y = 17
-4y = 17 + 21
-4y = 38
y = -38/4
y = -19/2

Answer:
He drove 111 miles
If we were given the distance Lan drove last weekend instead off how much gas he used then we would have to find the amount of gas used by lan.
Step-by-step explanation:
Ian's car can go 185 miles on 5 gallons of gas
On 5 gallons of gas lan's car can go 185 miles
Therefore in gallon of gas lan 's car can go
185/5 = 37
So, for 3 gallons of gas lan's car can go
3 × 37 = 111
for 3 gallons of gas lan's car can go 111 miles
If we were given the distance Lan drove last weekend instead off how much gas he used then we would have to find the amount of gas used by lan.
We get that Shannon did not mix the correct shade as the ratios are not equal.
We are given that a particular shade of paint is made by mixing five parts of red paint with seven parts of blue paint.
This means that the ratio of the paints in that shade is
Red : Blue = 5 : 7.
Now, we are also given that to make the correct shade, Shannon makes 12 quarts of blue paint with 8 quarts of red paint.
Here the ratio becomes:
Red : Blue = 8 : 12
= 4 : 6
= 2 : 3
Now, since both the ratios are not equal, he did not mix the correct shade.
Therefore, we get that Shannon did not mix the correct shade as the ratios are not equal.
