70 * 0.22 = 15.4
70 + 15.4 = $85.40
The total cost is $85.40
Answer:
The answer is -0.4
Step-by-step explanation:
First do the parentheses then multiple the answer with the number outside the parentheses.
Answer:
Step-by-step explanation:
This means the point travled to -5 on the x axis, then went down to -5 on the y axis, and then went +5 along the z axis
The top and bottom of the rectangle need to be equal and the two sides also need to be equal.
Set the equations to equal each other and solve for the letter.
Top and bottom:
3x-5 = x +1
Subtract 1x from each side:
2x -5 = 1
Add 5 to both sides:
2x = 6
Divide both sides by 2:
x = 6/2
X = 3
SIdes:
Now you know what X is replace x in the left side equation and solve:
2x-4 = 2(3) -4 = 6-4 = 2
The left side = 2, so the right side also needs to equal 2:
y-3 = 2
Add 3 to both sides:
y = 5
Answer:
Step-by-step explanation:
Given
Required
The solution
First, we equate both expressions.
Subtract x from both sides
Add 6 to both sides
Divide both sides by 3
Solve for x
To solve for y, we have:
This gives
