Answer: In solution
Step-by-step explanation:
Well, first you need to arrange the numbers in anyway, separated by operations. I just did:
-3.78 + (-1.2y + -4.2y)
We then need to come up with the other side of the equation.
For this, I added the like terms:
-3.78 + (-1.2y + -4.2y) = -3.78 -5.4y
Then, I came up with a value for y. Y = 5
Then, I multiplied -5.4 by 5, getting -27 so,
-3.78 + (-1.2y + -4.2y) = -3.78 - 27
Again, I collected like terms:
-3.78 + (-1.2y + -4.2y) = -30.78
Now, I have my equation.
———————————————————————————————
HOW TO SOLVE THE EQUATION
-3.78 + (-1.2y + -4.2y) = -30.78
1. Add 3.78 to both sides
-1.2y + -4.2y = -27
2. Collect like terms
-5.4y = -27
3. Divide both side by -5.4
y = 5
Answer:-
-3.75 + -1.2y = -4.2y
Step-by-step explanation:
the answer would then be that y= 1.26 when solved

what iswrong with this one
He made an error in step 1. Specifically, he distributed incorrectly.
The 3(x+2) portion is not the same as 3x+2. We need to multiply that '3' by the 2 as well to get 3*2 = 6
In other words, 3(x+2) should turn into 3x+6
If you wanted, you can think of 3(x+2) as three copies of (x+2) added together like this: (x+2)+(x+2)+(x+2) = (x+x+x)+(2+2+2) = 3x+6

Mrs. Stephan took her children to pick out pumpkins. Cater picked out a pumpkin priced $20, and Isabel picked out a pumpkin priced $13. How much did Mrs. Stephan pay for both pumpkins, including 7% sales tax?
Answer:
$35.31
Step-by-step explanation:
(20+13) x (1+0.07) = 35.31
You add the price of both pumpkins together to get the price of the pumpkins before tax. Then you multiply it by (1 + 0.07) because 1 is the regular price plus the sales tax which is a percent that can be converted to decimal to 0.07. You multiply these together and get 35.31
Answer:
$35.31
Step-by-step explanation:
(20+13) x (1+0.07)

(4 to the 2th power - 8 + 2 x 10) divided ( 3 to the 2 power - 5
Answer:
7
Step-by-step explanation:
(4^2 - 8 +2 * 10) / ( 3^2 - 5)
(P) E M D A S
Solve inside of perithesis first:
((4^2) - 8 +2 * 10) / ((3^2) - 5)
P (E) M D A S
4^2 = 16 , & 3^2= 9
Plug in:
(16 - 8 + 2 * 10) / (9 - 5)
P E (M) D A S
2*10= 20
Plug in:
(16 - 8 + 20) / (9 - 5)
P E M D (A S)
in order from left to right:
16-8=8, 8+20=(28)
&
9-5=(4)
Plug in:
28 / 4
P E M D A S
28/4= 7
Answer: 7
