Answer:
if they are similar then their sides are proportional and the following would be true:
40/30 = 48/36
reduce both sides:
4/3 = 4/3
so, yes, they are similar.
Step-by-step explanation:
Subtract 7 from -2 and 7 since 7 is currently a positive number
Your equation should now look like this:
-3x=-9
Next you have to divide by 3 on each side to get:
X=3
Answer:
the answer is 11.66
Step-by-step explanation:
because 3 cant give 0 anything 9 will make 1, 2 but 2 cant change 6
I think the answer to this is: 25q + 10d + 5n + 60 = 87
The story says that you have 1 dollar and 87 cents; 60 cents of which is pennies. So, if you’re using an equation involving quarters, dimes and nickels, the total equation should equal to 87 cents (since that dollar bill could not be broken down to cents).

x + -1.4 = 7.82
Reorder the terms:
-1.4 + x = 7.82
Solving
-1.4 + x = 7.82
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '1.4' to each side of the equation.
-1.4 + 1.4 + x = 7.82 + 1.4
Combine like terms: -1.4 + 1.4 = 0.0
0.0 + x = 7.82 + 1.4
x = 7.82 + 1.4
Combine like terms: 7.82 + 1.4 = 9.22
x = 9.22
Simplifying
x = 9.22</span>
