Answer:
Problem 13: yes
Problem 14: no
Step-by-step explanation:
Problem 13:
Plug the values of x and y to solve.
-23 = -7(5) + 12
-23 = -35 + 12
-23 = -23
The values are equal, so the coordinates <u>do</u> solve the equation. It's a yes.
-----------------------------------------------------------------------
Problem 14:
Plug the values of x and y to solve.
-9 = -7(-3) + 12
-9 = 21 + 12
-9 = 33
The values are not equal, so the coordinates <u>do not</u> solve the equation. It's a no.
hope this helps :)
Answer:
1 1/30 gallon
Step-by-step explanation:
Can A = 1/3 gallon
Can B = 1/5 gallon
Can C = 1/2 gallon
Total paint Neil has = Can A + Can B + Can C
= 1/3 + 1/5 + 1/2
The lowest common multiple of 3, 5 and 2 is 30
= (10+6+15) / 30
= 31/30
= 1 1/30 gallon of paint
Neil has a total of 1 1/30 gallon of paint
A+b = c+d
a+b = 770/2 ( a+b+c+d = 770)
a+b = 385
c+d = 385
a+b+a-b = 385+49
2a = 434
a = 434/2
a = 217
a-b=49
217-49= b
b = 168
c+d+c-d = 385+211
2c = 596
c = 596/2
c = 298
c-d = 211
c-211= d
298-211 = d
d = 87
Therefore, a=217, b=168, c=298, d=87
Answer:
1/1296
Step-by-step explanation:
Assuming that the probability of rolling a number is the same (1/6), all we have to do it multiply 1/6 by 4 (the number of times you roll the dice).
So 1/6 * 1/6 * 1/6 * 1/6 is just 1/6^4 and 6^4 is 1296.
Therefore the probability of rolling a 6 4 times in a row is 1/1296.
F/3 + 22 = 7
subtract -22 to both side
f/3 = 7-22
f/3 = -15
multiply by 3
f = -45
