X + 4y = 7 as they both equal the answer. Hope this helps
A powerful way to find out is to solve the equation. Let's try that.
3 (d + 11) = 6 (d + 33)
Eliminate the parentheses: 3d + 33 = 6d + 198
Subtract 3d from each side: 33 = 3d + 198
Subtract 198 from each side: -165 = 3d
Divide each side by 3 : - 55 = d
There it is ... the solution to the original equation.
'd' has to be -55, otherwise the original equation isn't a true statement.
-55 is the ONLY number that 'd' can be. If you write in any other number
for 'd', the equation will be false.
For example, less see what the equation says when d=2 :
3(2 + 11) = 6(2 + 33)
3( 13 ) = 6( 35 )
39 = 210
Is that a true statement ? Is 39 equal to 210 ?
No. 39 and 210 are not equal. They are different.
So the equation is not true when d = 2 .
The equation is true ONLY when d = -55 .
The equation has exactly one solution.
Answer:
x = 2
Step-by-step explanation:
63x - 1 and 62x + 1 are corresponding angles and congruent, thus
63x - 1 = 62x + 1 ( subtract 62x from both sides )
x - 1 = 1 ( add 1 to both sides )
x = 2
The answer is 12y^2 + 2y - 5
The solution:
(72y^3 + 12y^2 - 30y) / 6y =
(6y)*(12y^2 + 2y - 5) / 6y = 12y^2 + 2y - 5
Answer: The product of 42 times 43 is 1,806
Step-by-step explanation:
42 and 43 are both factors, and factor x factor = product
42(factor) x 43(factor) = 1,806(product)
To check work, divide the product by one of the factors, and the result should be the other factor.
1,806(product) divided by 42(factor#1) = 43(factor#2)
-or-
1,806(product) divided by 43(factor#2) = 42(factor#1)
