Answer:
5,589,000
Step-by-step explanation:
5.589 x 1,000,000=
5,589,000
Using the distributive property, a(b+ c) = ab + ac. In this case, b is 30, so the blank is 30.
Step-by-step explanation:
Taking any two points through which the line passes;(-10,-3) and (-5,-1)
The equation of the line is given by
=> 5y+15 = 2x+20
=> 5y =2x+5
option C
Answer:
?? = 900
Step-by-step explanation:
Solve algebraically
let x be ball and y be cube
x + y = 100
x - y = 80
xy = ??
We can solve by elimination. Eliminate one of the variables by adding OR subtracting the entire equations. I will add.
. x + y = 100
<u>+ x - y = 80</u> y + - y = y - y = 0; The variable is eliminated
. 2x = 180 Divide both sides by 2 to isolate x
. x = 90
Substitute x = 90 into one of the equations.
x + y = 100
90 + y = 100 Isolate y by subtracting 90 from both sides
y = 100 - 90
y = 10
Find xy = ?? by substituting y for 10 and x for 90.
xy = (90)(10) = 900
Therefore the value of ?? is 900.
Square root (x + 8) -6 = x
square root (x + 8) = x -6
x^2 + 16x + 64 = x^2 -12x + 36
28x = 48
x =
