If my caculations are correct is 6 dollars and 90 cent. please tell me if im wrong.
Answer:
A. 7*5 + 4^2 - 2^3 / 4 = 35 + 16 - 8 / 4 = 35 + 16 - 2 = 49
B. The statement of seven times five plus four squared minus 2 cubed divided by 4 is equal to 49. (or whatever your friend's teacher wants when they ask for a complete sentence).
C. PEMDAS - parentheses, exponents, multiplication, division, addition, subtraction
Note:
When remembering PEMDAS, please remember that multiplication actually isn't prioritized over division - they should be performed "simultaneously" from left to right. Same with addition and subtraction. The order is: P -> E -> MD -> AS.
Answer:
[see below]
Step-by-step explanation:
A system of equations with no solution would show parallel lines. We just have make a equation that is parallel to the original equation.
The slope of 2x + 8y = 12 is
, and it's y-intercept is
.
Since parallel lines have the same slope but not the same y-intercept, I would use
.
Any equation that has -1/4 as the slope would work.
When graphed together, they show as a system with no solution.
Hope this helps.
Answer:
4
Step-by-step explanation:
3+(-2) is the same as 3-2 which is 1. and since with multiple exponents you work from the top you have 4 to the power of 1^4. 1^4 is 1, so it's 4^1, which is 4.
First you have to estimate.
$3.98 —>$4.00
$4.19 —>$4.00
$0.79 —>$1.00
Then we need to add.
4+4+1=9
So the answer is C, $9
