Answer:
a. 60
b. -32
c. 3598
d. -6
Step-by-step explanation:
all you have to do is plug in the numbers that are given to you for the missing variables and then solve it regularly.
6×7+2×3
5×(-18)÷3-2
(6×10)^2-10÷5
(1-3)(1+2)
Answer:
54ab
Step-by-step explanation:
the only two factors of 54ab^2 and 54ab is 1 and 54ab and the greatest of that would be 54ab.
The answer is -10 because when u plug in -2 for x u get 4(-2)=-8 then -2+-8=-10
Answer:x = -9, y = -7
Step-by-step explanation:
Equation 1) -x + 4y = -19
Equation 2) -3x + 3y = 6
Multiply ALL of equation 1 by 3 so that both equations include -3x in it.
1) 3(-x + 4y = -19)
Simplify.-3x + 12y = -57 → equation 3
Now, subtract equation 3 from equation 2.
-3x + 12y = -57
(-)-3x + 3y = 6
Simplify.
9y = -63
Divide both sides by 9.
9y ÷ 9 = -63 ÷ 9
Simplify.
y = -7
Now that we have the value for y, simply plug in -7 for y into equation 1.
1) -x + 4y = -19-x + 4(-7) = -19
Simplify.-x - 28 = -19
Add 28 to both sides of the equal sign.
-x - 28 + 28 = -19 + 28
Simplify.-x = 9
Divide both sides by -1.x = -9
Now we know that : x = -9, y = -7
To check our work, simply plug in -9 for x and -7 for y into equation 1.
1) -x + 4y = -19-(-9) + 4(-7) = -19
Simplify.
9 - 28 = -19-19 = -19
Therefore, x = -9, y = -7
Hope this helped! :)
