Answer:
x = -2 u got this
Step-by-step explanation:
-7x = 4x + 22
-11x = 22
x = -2
Easy bro
To solve the system of equations by substitution, solve one equation for one variable and substitute the expression into the other equation. In this case, solve the first equation for y, then substitute that value of y into the second equation. Solve for x and substitute the value back into the first equation to find y. The solution to the system of equations is x = -2 and y = 14.
To solve the system of equations by substitution, we need to solve one equation for one variable and substitute that expression into the other equation.
In this case, we can solve the first equation for y:
y = −7x
Now we substitute this value of y into the second equation:
−7x = 4x + 22
Next, we solve this equation for x:
−7x - 4x = 22
-11x = 22
x = -2
Finally, we substitute this value of x back into the first equation to find y:
y = -7(-2)
y = 14
Therefore, the solution to the system of equations is x = -2 and y = 14.

June spent 20$ on ice cream.
Answer:
4
Step-by-step explanation:
she should have only spent 4 dollars. she spent a total of 40$ and 10%of that was on ice cream. to figure that out divide 40 by 10 percent since it is a fair ratio of 100% you will get 4.
For every 3.3 km rock is buried, the pressure placed upon it increased 0.1 Giga pascals.
We need to find the pressure placed on that rock at 16 km.
Let us divide 16 km by 3.3 first to find the number of 0.1 Giga pascals would be there.
16/3.3.
On dividing 16 by 3.3, we get 4.8485.
In order to find the number the pressure placed on that rock, we need to multiply 0.1 by 4.8485, we get
0.48485 Giga pascals.
