Answer:
Ok ill get back to you when I figure it out so see you in 5 minutes!
Answer:
Thomas has 45
Emma 30+45=75 pound
Step-by-step explanation:
Ratio is 3/5
Tomas receives x money
Emma receives x+30
3/5=x/30+x
3(30+x)=5x
90+3x=5x
90=5x-3x
90=2x
x=90/2=45
Thomas has 45
Emma 30+45=75 pound
45/75=3/5
j^3
_______
4^2 h^4
when you have negatives, you want them to be positive. To do that you need to convert it into a fraction
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.
