Answer: Maria payed $58.00 for her jacket BEFORE tax.
Step-by-step explanation:
To find the answer to this question, we must first multiply 72.50 by 0.20. After doing so, we get 14.5 (this is the sale money). Finally, we subtract $72.50-14.5 to get out answer, 58 dollars.
2(x^2+5)=60 to 2x^2+10=60
distributive property (a(b+c)=ab+ac)
2x^2+10=60 to 2x^2=50
property of equality or something like thht (a=a and b=b, so a-b=a-b) and also
addative inverse (a+-a=0) (added -10 to both sides)
2x^2=50 to x^2=25
propery of euality and multiplicative inverse (a times 1/a=1) and one produce property (1 times a=a)
x^2=25 to x=+/-5
property of equality and something else
Answer:
slope=2
I think that you can use demos it is a calculator just put the point and you get the answer
Answer: 4. 78,020,008 4. Seventy-eight million, twenty thousand, eight
5. 20,011,012 5. 20,000,000 + 11,000 + 12
6. 50,000 7. 900 8. 70,000,000 9. 30,000,000
Step-by-step explanation:
The measures of two angles have a sum of 90º if and only if the angles are complements.
if the angles are complementary they have to equal 90 otherwise they are not complementary
